Cisco Enhances VXLAN: Eliminates IP Multicast Requirement, integrates virtual services via vPath plus connects to legacy networks

Listen to the Podcast

May 27th, 2013

Han_Yang_Cisco_Enhances_VXLAN_Eliminates_IP_Multicast_Requirement_integrates_virtual_services_via_vPath_plus_connects_to_legacy_networksCisco introduced enhancements to its VXLAN implementation in the Nexus 1000V virtual switch that overcomes the requirement for IP Multicast. In addition Cisco is integrating vPath to VXLAN for service insertion that stitches virtual services into VXLAN overlay tunnels. Network services might include virtual firewalls, application delivery controllers, WAN optimization, network monitors, etc. A final VXLAN challenge that network teams are facing is how to integrate VXLAN into legacy networks and with existing physical networks, appliances and the enterprise WAN. We’ll hear if Cisco has any solutions to get around this issue as well. Han Yang of Cisco joins me to discuss VXLAN, without multicast and with vPath, and how it can be used to deploy virtual network overlays.

Extreme Networks Addresses Scale Issues with its Open Fabric Software-Defined Networking

Listen to the Podcast

January 14th, 2013

No matter where an IT architect looks they are confronted with scaling issues and many times one solution creates another problem.  To address increasing VM density many are expanding broadcast domains with flatter 2-tier architectures only to get bogged down in broadcast issues.  To scale virtualized networks the industry offers VXLAN, but that moves L2 scaling into a multicast-scaling problem.  Software-Defined Network and in particular OpenFlow offers a good approach for provisioning and control but introduces flow oriented architecture scaling issues of its own.  I discuss scaling challenge with Shehzad Merchant Chief Technology Officer at Extreme Networks.

Duration: 10:24 minutes

Lippis Intro/Analysis @ : 00:10 sec

Question 1

@ 1:35 sec: Shehzad: Let’s first start with Extreme’s view of 40 and 100GbE.  How is Extreme incorporating it and why?

Question 2 @ 3:50 sec: Forwarding table architecture and size define logical networking scale.  Extreme recently introduced UFT or Unified Forwarding Table.  What is it and how does it work?

Question 3 @ 6:35 sec: Extreme has partnered with Big Switch Networks to address network visualization scale via its Big Tap and Big Virtual Switch.  Can you talk to this solution?

Question 4 @ 8:51 sec: Can you sum up all the initiatives that Extreme has under way to deliver on its Open Fabric architecture for clo

ud-scale networking?

This document provides an overview of how VXLAN works. It also provides criteria to help determine when and where VXLAN can be used to implement a virtualized Infrastructure. Arista, Broadcom, Intel, VMware and others developed the VXLAN specification to improve scaling in the virtualized Data Center.

The Changing Face of Data Centre Networks

By Quocirca

UK analyst firm, Quocirca, describes why fast and intelligent system networks, such as IBM’s, are of critical importance for the smarter data centre. As networking technology has standardised around Ethernet, the perception has grown that it has also commoditised. However, as technical architectures evolve to keep pace with the impact of virtualisation, cloud computing and high-performance workloads, the needs around networking are also changing. This is driving data centre operators to understand how recent performance advances and standards-based innovations in system networking infrastructures can meet the performance, scalability and agility requirements of today’s data centres.

Embedded DWDM and Distance Extension Solution

By Arista Networks

Data center operators are expanding data centers to deliver virtualized and cloud-based services including business continuity and disaster recovery solutions. These additional service and availability requirements lead to increased bandwidth and greater distances between geographically dispersed data center sites. As new services are added, data center environments that were once fiber-rich can quickly run out of fiber and find the associated cost for adding more fiber to be prohibitively expensive. Cost-effective embedded DWDM and distance extension solutions can reduce complexity, operating costs and enable a rapid delivery of new services. Find out how by downloading this whitepaper.

Renato Recio, IBM Fellow & System Networking CTO

There are a growing number of options to make data center networking more flexible. One option is the use of Edge Virtual Bridging or EVB, which has been standardized in project IEEE 802.1Qbg and championed by IBM, HP, Brocade, QLogic, Emulex and many others. This approach extends the Virtual Ethernet Bridge or VEB sometime called Virtual Ethernet Switch (VES) used by hypervisors to connect VMs to the data center network. Renato Recio, IBM Fellow & System Networking CTO joins me to discuss IBM’s approach to virtual network infrastructure overlays and in particular its support for Edge Virtual Bridging.

December 5th, 2011

By Zeus Kerravala, Senior Vice President and Distinguished Research Fellow

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.

Lippis Report 179: New Design Principles in Campus and Data Center Networking: In the Age of the Next Gen Catalyst 6K with Supervisor 2T

September 26th, 2011

By all counts, Cisco’s upgrade of the Catalyst 6K via its new Supervisor 2T, or Sup2T, is its most ambitious and thoughtful yet for the venerable platform. The Sup2T is a 2 Terabit (Tb) platform that triples the previous Sup720 performance. Thanks to the support of Virtual Switching System (VSS), the platform allows two 2 Tbps switches to combine into a single 4 Tbps virtual switch. The Sup2T is a major upgrade to the most widely-deployed switching platform in campus and data center networking in the industry. But while these performance numbers are impressive, it’s the new Cat6K’s network services and pricing that deliver most of the value. From a services’ point of view, the Cat6K stands alone.

Lippis Report 178: Nearly 2 Years after HP Buys 3Com for $2.7B, It Has Very Little to Show for IT: Can HP Make It in Networking?

September 12th, 2011

Back in November of 2009, I wrote Lippis Report Research Note 136 titled “HP Plans to Acquire 3Com Accelerating a New IT Convergence Era.” In that Research Note, I wrote

“When 3Com is fully integrated into HP what kind of networking revenue and market share can HP gain? ProCurve + 3Com is approximately $2B of revenue now. With the existing product lines can HP generate $5B, $10B or more of network revenue over five years? Time will tell.”

Well after nearly two years, HP Networking or HPN’s North America (NA) layer 2/3 Ethernet switch market share by revenue is nearly the same, bouncing between 5% and 6.1%, according Dell’Oro, with HPN’s Q2CY11 NA switch revenue share being down to 6%. Considering HPN’s limited results after significant investments in sales, channels and marketing, including its “proof-of-concept” plus “A Catalyst for Change” Cisco Trade-in program, not to mention engineering investment, the question is can HP make it in networking? We attempt to answer that question in this Lippis Report Research Note.
