With CAPEX accounting for only 20% of the cost of a network, it is important to look beyond initial expenditures and consider TCO and the business value a network can provide. A third-party TCO comparison of a Cisco network versus other vendors illustrates that Cisco can deliver a 13% better TCO even before business benefits, such as network uptime and employee productivity are considered. Further, the Cisco Borderless Network Architecture acts as a platform for service delivery, allowing your IT organization to say “yes” to business and revenue-enhancing opportunities.

Chicago-based real-estate management company Equity Office ran all its voice and data traffic over a 40-branch office network via a MPLS WAN, costing some $400K per year. But when poor peak-time performance drew complaints from end users, it switched to technology that delivers more bandwidth at half the cost, delivering a 10-month ROI. The new WAN blended DSL, cable, fiber and Ethernet over copper in a single local network via WAN virtualization from Talari Networks,

WAN bandwidth, or the lack thereof, is the single largest contributor to poor application performance in branch offices resulting in reduced productivity and the inability of IT to implement their entire strategy. This is especially acute as applications are increasingly centralized in data centers and video traffic starts to dominate flows all of which put more pressure on the WAN. A new approach to wide area networking takes advantage of virtualization concepts. WAN virtualization promises to reduce WAN cost and increase performance. If your WAN utilizes T1 MPLS links at $300/month or higher and ADSL between $10-$15/ month, then you can benefit significantly from WAN virtualization as it offers 3 to 4 times the bandwidth at lower cost and in the process eliminates WAN design constraints limiting IT business leaders. Keith Morris of Talari Networks joins me to discuss WAN Virtualization. I have first-hand knowledge of how good this solution works; if you fit the above profile, then listen up.

Having a plan to transition to IPv6 has moved way up in the priority list of IT projects for IT leaders as 2011 was officially the year we ran out of IPv4 unallocated addresses and not having IPv6 could cut-off corporations and applications from accessing the internet. In addition employees en masse are “BYOD” or bring your own device meaning smartphone and tables to work increasing the number of devices on the network significantly. These devices and their applications are driving support of both IPv4 and IPv6 as many mobile devices are now set for IPv6 as the default. As dual stack IP v4/v6 is the best practice, the real challenge lies within the domain name service or DNS. Infloblox has developed a range of solutions to automate the transition to IPv6 by supporting both addressing schemes. Tom Coffeen, Chief IPv6 Evangelist at Infoblox talks about solutions to automate the transition to IPv6. It’s one of our best IPv6 discussions.

The enterprise data center has undergone several major transformations since the introduction of computing as a corporate resource. The computing platform has evolved from main frame computing, to client server, to Internet-based computing, and now we sit on the precipice of the next major data center transition—the evolution to a fully virtualized data center. Each transition saw the cost of computing driven down and the importance of the network elevated. Each phase allowed organizations to increase the efficiency of their data center operations and improve asset utilization, ultimately leading to a better experience for end-users. This white paper provides a perspective on the rise of network value as it acts as the backplane for the virtualized data center and provides design recommendations.

The cloud model isn’t about transforming IT. It’s about reinventing the way organizations do business. Organizations in every industry, regardless of size or geography, are embracing cloud computing as a way to reduce the complexity and costs associated with traditional IT approaches. Organizations that approach cloud in a tactical fashion risk adding complexity and inefficiency (not to mention security exposure) due to fragmentation, redundancy and operating silos. Conversely, organizations that embrace cloud strategically—from a business as well as IT perspective—can capture new business value through innovation, flexibility, speed, integrity and security—while reducing cost and complexity.

To deliver the cloud’s full business value, cloud-enabled data centers require speed, flexibility, cost-effective operation and scalability. This paper discusses the technical and business requirements of cloud computing, focusing on the networking layer of the cloud.

Access Control List or ACL are important tools in the configuration and customization of network attributes, especially with the Catalyst 6500. In the Catalyst 6500 upgrade with Sup2T, the TCAM has been both increased and its architecture improved. For ACL, a major concern was the lack of visibility of TCAM overflows when new ACL scripts were submitted, disrupting network operation. Therefore, Cisco developed the ACL Dry Run and ACL Atomic Commit to mitigate this scenario. To verify ACL improvements, we use ACL Dry-Run to assure that the TCAM would not overflow, and then implement the changes safely with ACL Atomic-commit; assuring no network interruption. It’s a great short video that verifies how useful these new tools are in ACL management.

During the week of October 31, 2011, the Lippis Report tested Cisco System’s new Catalyst 6500 with Supervisor 2T or Sup2T for performance, upgradability, control and scalability at Ixia’s modern iSimCity laboratory in Santa Clara CA. By all counts, Cisco’s upgrade of the Catalyst 6500 via its new Sup2T, is its most ambitious and thoughtful yet for the venerable platform. The Sup2T is a major upgrade to the most widely-deployed switching platform in campus and data center networking. It’s the new Catalyst 6500’s network services that deliver most of the value, which is partially found in the Sup2T’s Policy Feature Card or PFC that increases NetFlow monitoring and a new TCAM design offering improved Access Control (ACL), Quality of Service design options, encryption security and many other features. This Lippis Report test verifies many of Cisco’s performance and upgradability claims. While it’s impossible to test all of the Catalyst 6500’s new 200-plus features with the Sup2T, we rather focus on a select few that will have the widest impact on IT business leaders’ product acquisition decision process.

MACsec encryption has become increasing popular and important to campus network design, but previous switch performance degraded when encrypted traffic was passing through it. Here we show that the catalyst 6500 does not suffer a performance degrade while MACsec traffic is passing through it. We tested the Catalyst 6500 via the cPacket Networks cTap 10G passive probe to verify traffic flows were either MACsec encrypted or unencrypted. We found that there is no material difference in throughput performance, other than 802.1ae encryption key overhead, thanks to 16 additional bytes per packet. The cPacket passive probe also measured line rate throughput performance. This is a great short video that verifies how the old encryption performance penalty is now gone.

For IPv4 and IPv6, dual stack implementations are most popular where desktops and mobile devices run both IPv4 and IPv6, therefore, the network infrastructure needs to support both equally at high performance. IPv6 performance has not been on par with IPv4 until now. To demonstrate how the Catalyst 6500 upgrade with Sup2T has improved IPv6 performance, we measure IPv4 and IPv6 unicast and bidirectional traffic performance via RFC 2544. IP Multicast traffic has been on the rise, thanks to the increased use of video services within the enterprise. Therefore, we test IP Multicast performance via RFC 3918 on the new Catalyst 6500 Sup2T to stresses its packet replication ASIC built into the 6908-10G line cards. We find that the new Catalyst 6500 delivers equal Ipv4 and Ipv6 performance; a 2x increase from the Sup720 for IP unicast, bidirectional and multicast forwarding.

One of the most impressive network design options available on the Catalyst 6500 is the use of VSS. Connecting two Catalyst 6500s equipped with Sup2Ts creates a virtual switch, adding each switch’s performance while operating as a single switch thus eliminating spanning tree in favor for active-active links. We configure two Catalyst 6500s via VSS. We measure throughput performance to verify that VSS throughput rates are equally high performance as the MPLS and VPLS scenarios. Check out the two-Catalyst 6500 configurations we deployed for this test.

During the Lippis Report test of the Cisco Systems Catalyst 6500 at Ixia’s iSimCity we perform an upgrade from Supervisor Engine 720 to 2T. What IT business leaders are looking for are incremental network upgrades with minimal disruption. Therefore, we swap out Sup720 for Sup2T and bring up existing service modules and line cards. Remember that line cards represent the largest investment in switching equipment, so we’ll demonstrate that older line cards interoperate at high performance when the new Sup2T replaces the Sup720. We find that the upgrade process is easy and smooth with compatibility of line cards, configuration code, service modules, transceivers and chassis.

Just as 10 Gigabit Ethernet (GbE) is going through widespread
deployment in the data center, the discussion has now shifted to even
higher speed interconnects—namely 40 GbE and 100 GbE
By IBM

In July 2006, the Institute of Electrical and Electronics Engineers (IEEE) Higher Speed Study Group was formed to look into the next evolutionary step after 10 Gigabit Ethernet (GbE). In the past, Ethernet speeds would increase by a factor of 10. However, the next generation jump from 10 GbE to 100 GbE has proven to be a technological challenge. Some within the IEEE group felt that 100 GbE made sense for communication service providers and other backbone network providers, but not as a next step for servers—it was simply more speed and expense than would be needed for the near future. While the IEEE initially planned to standardize only on 100 GbE as the next step after 10 GbE, server vendors initiated a push in early 2007 to include 40 GbE in the standard, with the rationale that the effort used to develop 40 GbE would be used for the development of 100 GbE.

In July 2007, the IEEE 802.3ba study group was named, and it is the first standard to include two different Ethernet speeds—the 40 Gbps rate for local server applications, and the 100 Gbps rate for internet backbone—to serve both market needs. In June 2010, the official 802.3ba standard was ratified, opening the field to higher performance in server systems and components, data centers, network storage and systems, high-performance computing (HPC) clusters, data centers, carriers, and the like. This paper provides perspective on the placement and use of 40 and 100GbE.

It can be easy to forget how much depends on the enterprise network—until you have to tell the VP of sales that he can’t use his iPhone on the corporate network because the appropriate security controls aren’t in place. Or you must tell the CIO that expanding the virtualization initiative to include business-critical applications will severely tax bandwidth. The truth is, nearly everything in modern businesses is dependent on the enterprise network, and every decision you make is based on whether the network can handle it. This paper takes a look at a common pitfall in IT circles that can have a serious impact on the IT decision maker’s ability to say “yes” to new business initiatives. It also offers recommendations for IT organizations that wish to act as business enablers.

Simplified and optimized service orchestration maximizes the return from a virtualized computing environment
By Avaya

This white paper discusses Avaya’s approach to Data center Networking from a fabric perspective. Virtualization within the data center is now taken for granted, with some declaring that ‘Cloud Computing’ will be the choice of most enterprises and that applications and information will become commodities. Experience has proved one thing; the data center of the future cannot be built on the technology of the past. General-purpose products, outmoded techniques, and legacy designs cannot be re-packaged as ‘data center-ready’. Ethernet is readily available, cost-effective, extensible, and – as the 40/100 Gigabit developments prove – scalable.

A third-party business consulting firm analyzed the total cost of ownership (TCO) of Cisco enterprise customer networks, and contrasted that TCO to “good enough” networks from other networking vendors. Key findings:
1) TCO is a better metric than CapEx to assess network cost because it considers the full impact on IT spend, including CapEx, services, labor, bandwidth and energy.
2) The Cisco Borderless Network Architecture can deliver up to 13% better TCO than a “good enough” network, offering compelling value for the strategic Cisco investment.
3) Even if architectural benefits are discounted in the analysis, Cisco is, at most, a 7% TCO premium over other vendors due to IT labor savings and extended product lifecycles from Cisco solutions.
4) The single biggest benefit of Cisco’s architectural approach is labor savings. Labor constitutes 50% of TCO and Cisco delivers 5% to 10% labor savings driven by unified wired and wireless and embedded security.
5) A quality network delivers business benefits beyond TCO, including improved network uptime, higher user productivity and a lower threat of security breaches.

The problems of network configuration changes required when virtualization operations managers need to move a VM between subnets are well documented. There are virtual networking options to solve this problem such as building very large flat networks, tunneling between subnets, and now a standard approach called VXLAN. VXLAN is a special encapsulation mechanism that runs between virtual switches and enables VMs to be deployed and moved on or between any server within the network. VXLAN requires no changes to the underlying IP addressing architecture and should require no major changes to installed infrastructure in the data center. Ken Duda Founder and Vice President, Software Engineering at Arista Networks joins me to discuss VXLAN, the first major protocol of virtual networking.

VMWARE VXLAN is a new network technology developed by VMware that enables stateful VM mobility across traditional L3 routed boundaries. This enables more freedom and flexibility in matching workloads to computing power. By enabling a larger, and essentially flatter network while building on top of proven models for stable scaling of networks such as routing and equal-cost multipath forwarding, VXLAN enables any workload to be provisioned on any virtualized host, anywhere in the network that is IP reachable. No longer do routed topology decisions restrict workload mobility.

If you are a VMware and network administrator who is building virtualized networks with more than 250 VMs or want to stretch a virtual machine farm across two data centers or two or more routed domains with full workload portability, then you need to read this white paper.

Organizations of all sizes are transitioning to virtualization technology at a dramatically increasing rate. Conducted between September and December 2010, Gartner’s annual survey of 2,014 CIOs collectively responsible for $160 billion in IT spending in 50 countries across 38 industries found that “Currently, 3% of CIOs have the majority of IT running in the cloud or on SaaS technologies, but over the next four years CIOs expect this number to increase to 43%.” The motivation for adopting the new technology is enticing: increased flexibility, decreased workload for internal IT departments, faster access to on-the-fly infrastructure needs, increased worker productivity, and significant capex cost reductions. Despite this worldwide trend across all industries, most organizations will fail in the conversion process to these new technologies, thanks to complexity. This white paper explains how network automation calms complexity allowing IT business leaders to reap the rewards of dense virtualization deployment.

As data centers scale to support thousands of servers, IT managers are seeking better ways to network those servers while reducing costs and power consumption. Moreover, in large-scale data center cluster environments, inter-node communication bandwidth is increasingly becoming the main bottleneck. Compute nodes located across different physical switches may not have full bandwidth in a conventional hierarchical network design of interconnected switches. The solution is a distributed core architecture based on low-cost, high-capacity switches. This paper describes the use of Force10 Network’s® Z9000™ core switching system in a distributed core architecture to address these issues.

Consider how central and critical the capabilities that the network provides are to business goals. In all other areas of the company, business leaders look to strategic thinking and innovation to pull the company ahead of its competitors. Why should the network be any different? The allure of the tactical is always present in any business. A “good-enough-for-now” network may solve some of the problems of today, but does it set up businesses to solve the problems of tomorrow? When the network fails to adapt to the challenges of the future, the business follows the same path. Taking a strategic approach to the network is not just a good idea. It makes business sense. This white paper argues the strategic importance of the corporate network to achieving business objectives.

In the quest to build a data center network that is flat, fast and fault tolerant, the networking industry has served up a new two-tier architecture made up of Top-of-Rack or ToR server connecting switches and highly dense Core switches. Core switches connect ToR devices. The key question is how best to provide switch connectivity to deliver a lossless, high performance, low latency fabric that supports virtualization mobility. The answer is found in Multi-Chassis Link Aggregation Group or MC-LAG, Transparent Interconnection of Lots of Links or TRILL and/or Shortest Path Bridging (SPB). Dhritiman Dasgupta, Director of Product Marketing for Fabric and Switching Technologies at Juniper Networks, discusses its QFabric approach and why TRILL’s hair pinning method to inter-VLAN routing is a poor approach.

Cloud computing is an emerging computing model that promises a new era of flexibility and control in providing data center resources. In the cloud model, data center managers can mix and match computing, storage, and networking resources to provide an agile and highly flexible resource for customer applications. To realize the full potential, this paradigm requires open, standardized interfaces between data center layers of compute resources, the network, and storage elements. While the industry has moved toward open computing and storage layers over the past few years, networking has remained largely proprietary. Force10’s Open Cloud NetworkingSM framework is intended to unlock the network layer so data center operators can get the most out of their data center architectures and, in turn, get the most out of their cloud deployments.

Cloud computing is gaining customer attention at a fascinating pace. An Infonetics research report published in early 2011 noted a significant increase in customers’ interest in cloud computing between 2009 and 2010—most of respondents indicated interest in 2010, up from only 10% in 2009. Many studies have concluded that software as a service (SaaS) and infrastructure as a service (IaaS) are leading the way in adopting cloud computing. Meanwhile according to an April 2011 Forrester report, the third largest cloud category, platform as a service (PaaS) is predicted to surpass IaaS to become the second largest cloud category by 2014. But according to Forrester, security is one of the top barriers to cloud computing. This white paper details an approach to secure cloud computing to mitigate threats and increase its adoption.

Although line shipments for IP telephony have outstripped TDM for some time, many organizations have not yet fully replaced their TDM phones. In fact, only 17% of companies have fully deployed the technology, and the bulk of those are small and midsize businesses. Larger organizations have rolled out the technology in a spotty manner where the TDM system is end-of-life, or other tactical reasons. IT organizations are evaluating the economics, plus desktop IP phones investment when people increasingly rely on mobile devices and soft clients.

Many others are re-evaluating the market as they solidify unified-communications plans and once again contemplate go-forward strategy for IPT. Will they use the same vendor(s)? Will they shift to a hosted- or managed-services model? And what is the true business case? Understanding the true costs is crucial to a successful business case—and a cost-effective implementation.

Today’s data center networks are under tremendous pressure. Not only are they growing geometrically to keep pace with rapidly escalating business demands, support new application architectures and virtualized environments, and improve the overall user experience, they are expected to do so more efficiently and more cost-effectively than ever before.

The problem lies in the fact that, while everything else in the data center (applications, storage, servers) has evolved over time, the network architecture itself has not. Rather than evolve, the data center network has instead become extremely complex. This
complexity prevents the network from scaling properly, restricting available resources and limiting the ability to virtualize the data center. The Juniper Networks 3-2-1 Data Center Network Architecture delivers a strategy for simplifying the data center by flattening the existing multilayer tree structure to improve overall performance as well as the user experience.

The data center is undergoing tectonic shifts with virtualization the primary cause. Everything is moving faster within the data center—moving at the speed of virtualization—putting centers into a state of transition from physical to virtual, which can be long, complex and messy. At the same time, security models remain largely static, anchored by physical security devices. Not only does this put the organization at greater risk, it also puts in jeopardy the core benefits of virtualization. To address this, organizations need a security architecture delivering agile security and supporting the physical infrastructure, the virtual infrastructure, and all the transitional states in between the two. This requires a new security model seamlessly integrating existing security controls for physical infrastructure with comparable security controls for the virtual infrastructure. This new model requires virtualization security.

IT business leaders are being confronted with a choice: either embrace users’ freedom or liberty to choose a mobile endpoint and applications that they deem appropriate to support their work, or dictate a limited number of supported mobile endpoints and applications in which employees must choose? At the center of this decision are security concerns and control as the number of mobile endpoints connecting into enterprise networks skyrocket. A larger secondary effect is that employees are downloading low cost (99 cents to $4.99) mobile applications, which is changing the mix of corporate application portfolios without IT visibility but user request for support. At the same time, video communications is expanding throughout the enterprise and the endpoints it supports. IT business leaders can avoid this difficult choice and offer users freedom to choose the mobile endpoint and applications of their liking, and still maintain security and control by deploying a Borderless Network. In this industry white paper, we review market dynamics shaping mobile computing plus video communications and how a Borderless Network offers user choice, IT management control and in the process, a more productive and agile workforce.

The movement on the part of enterprises to adopt a Cloud-based service model combined with the growing interest on the part of IT organizations to provide an internal SLA (Service Level Agreement) for the services they provide creates tremendous opportunities for Communications Service Providers or CSPs. The primary opportunity is for CSPs to offer a wide range of network centric solutions that are supported by an SLA. CSPs are in a unique position to offer these solutions because, unlike the Internet, the Next Generation Networks (NGNs) that CSPs have deployed are capable of providing contracted levels of availability, delay, jitter and packet loss. This paper provides three recommendations for CSPs to capture Cloud-based service revenues.

Private clouds describe an architecture in which servers and networks in the data center can rapidly respond to changing demands, by quickly scaling compute capacity and connecting that server capacity where it is needed. The technology underlying this fluidity is server virtualization, which by now has been established as a reliable and essential core technology for most data centers. Five critical networking technologies are needed to build a private cloud network:

• Up to 1.28Tbps of line-rate, loss-less bandwidth
• Single-wire networks for data and storage with DCB support
• Support for thousands of virtual ports
• Virtual machine awareness
• Extremely low power requirements

This white paper details a cloud network architecture that incorporates these five success factors.

Today, virtualization, cloud computing and high frequency trading place new demands on the system network fabric to deliver non-stop, ultra low-latency traffic flows. This traffic is increasingly “east-west” in nature to enable machine-to-machine communications versus the “north-south” traffic that characterizes conventional client/server and Web-based application environments. To deliver this east-west traffic using the most efficient flows, large flat networks are becoming increasingly popular. These flat Layer 2 networks eliminate extra hops to decrease latency, do not block any paths across the network, and are simple to configure. Such flat networks are built with large numbers of inexpensive top-of-rack switches, scale horizontally by simply adding more switches, and enable VLANs to span across a data center to provide larger server pools for virtualization. TRILL or TRansparent Interconnection of Lots of Links is fundamental to IBM’s approach and is explained in this white paper.

Other reseach and analysis firms seem to see IBM’s acquisition of BLADE Network Technologies (BLADE) as a competitive response to
Hewlett-Packard’s acquisition of 3Com and Cisco’s entry into the blade server business, but there’s much more to this deal than competitive dynamics. Clabby Analytics believes that data center virtualization is accelerating, and the demand for more I/O per server is on the rise. Additionally, networks are converging around a single Ethernet wiring plant. These industry changes are the true driving factors in this deal.

As IT operations become more complex, it steals productivity. Unchecked complexity slows down new applications from being deployed or virtualized, elongates troubleshooting, stresses operational staff, creates compliance vulnerabilities and shrinks IT operational budgets. All IT departments seek to manage this complexity inflation before it impacts business processes. One of the largest drivers of complexity inflation is the growing rate of “IP addresses and network change management requirements.” The fact is that IT business leaders must deploy dynamic IT solutions to enable their businesses to support flexible business processes to address market dynamics. Without automated tools to facilities change management, complexity inflation simply eats up IT operations. In this Lippis Report podcast, I talk with Steve Garrison, Vice President, Marketing for Infoblox, about solutions to tame complexity inflation with automated IP address management and network change management.

Deploying network services in virtual data centers is extremely challenging. Traditionally, such Layer 4 through 7 services relied on intrusive, inline deployment and static network topologies. They were thus completely at odds with highly scalable virtual data center designs with mobile workloads, on-demand virtual machine (VM) provisioning, and strict service-level agreements (SLAs).

Cisco® Unified Network Services (UNS) addresses all of these problems by creating a framework for multiple services that can be configured and provisioned on demand, dynamically, to suit the service needs of enterprise applications and cloud users. This dramatically reduces network management overhead, allowing for a much more agile data center and business while providing improved application performance and a secure infrastructure. Cisco UNS comprises Cisco’s industry-leading solutions for virtual data centers that deliver.
