In a fireside chat format, recorded recently at CiscoLive with Steven Shalita, Vice President of Marketing at NetScout we discuss how NetScout fits into the Cisco Application Centric Networking ecosystem and free discussion on the pros and cons of the major industry changes taking place. We chat about organizational models to optimize service delivery, why end-user experience has become such a high priority metric and how to measure it, how do to improve the success of rolling out new services, why should the network professionals care about application performance and how does Software Defined Networking (SDN) and Function Virtualization (NFV) change things?
As the transition to open networking technologies progresses, NetScout seeks to add value by minimizing disruption and preserving excellent user experience by being a bridge between the old and the new worlds of open networking. At the Open Networking User Group or ONUG Spring hosted by Citigroup in New York City, IT business leaders discussed their transitioning to open networking technologies such as network virtualization or overlays, software-define WAN and LANs, linux based tools to automate the configuration and change management of networking, storage and servers, OpenStack, white box based underlays and much more. While no two firms are at the same point of transition, what was very clear is that all are in transition. Recorded recently at CiscoLive with Steven Shalita, Vice President of Marketing at NetScout we discuss how NetScout can bridge the transition from today’s networks to the new world of open networking.
NetScout’s business focus is on providing performance management that spans applications to network stack. To control application performance an automated way to create of an application dependency map that spans applications, compute, storage and networking across data center, campus and WAN. An application dependency map enables cross-functional application troubleshooting and performance optimization. This is the Holy Grail of IT as it enables business resiliency and lowers OpEx. NetScout is in an optimal space to deliver this value. We’ll find out how they are approaching performance management in this Lippis Report podcast, recorded recently at CiscoLive with Steven Shalita, Vice President of Marketing at NetScout.
Cisco Launches Industry’s Broadest Networking Programming Environment with Its New Nexus® 9000 Product Line
Today’s networks are restricted to configuration programming via CLI, but what if applications can call upon network resources automatically or if application developers are provided access to network state, topology, performance and other information? How might applications change and user experience improve? How may a networking programmable environment enable automated provisioning, orchestration and management? Could a programmable network enable a new era of IT and an industry of network aware applications just when the Internet of Things is starting to emerge? The Cisco Nexus® 9000 product line provides a wide range of programming options through an enhanced version of the Nexus Operating System (or NX-OS) that ranges from APIs to direct programming via its built-in Linux BASH environment, RPC, RESTful APIs, JSON, Python etc. I’m joined by Bradley Wong, Distinguished Engineer, Technical Marketing at Cisco, as we review the Cisco Nexus programming environment, its programming options provided to developers, use cases and potential industry impact.
Duration: 14 minutes 4 seconds
To understand the depth of the Cisco Nexus® 9000 programming environment, Lillian Quan, Technical Marketing Engineer at Cisco, demonstrates the richness of this new platform. We start with standard CLI comments then move to the Nexus API environment that generates JSON or XMP code. We then utilize this code to demonstrate automation of repetitive network engineering task via Splunk and real-time graphic of network data via Graphite to create a NOC dashboard. After watching this video, network engineers will want to enroll in a Linux course while DevOps will finally be able to use familiar tools to access network data and information.

Cisco Nexus® 9508 Sets New High Performance Latency Test Result Record of 1.6 to 3.5 microseconds Spine Switch Populated With 288-40GbE Ports
While most companies announce products long before first customer ship with long road maps of when product features are available, Cisco’s Nexus® 9508 is ready now. The independent and open industry Lippis/Ixia team test the Nexus® 9508 at 288-40GbE capacity for layer 3 unicast plus IP multicast latency and congestion management via RFC 2544, 3918 and 2889, respectively. This test is a new industry record as no other data center switch has been tested at 288 40GbE ports. What are really impressive are the results and the engineering achievement of the Cisco team. I’m joined with Bradley Wong, Distinguished Engineer, Technical Marketing, at Cisco, as we review the Cisco Nexus® 9508 test methodologies and results.

There is a fundamental shift occurring in network engineering skill set requirements as open networking and Software-Defined Networking technologies continue their rapid deployments. DevOps will have a larger role in network purchases. New network designs are emerging, thanks to virtual overlays, white box networking, Linux-based network-programming tools, OpenFlow based pSwitches and vSwitches, etc. The CCIE skills set is being augmented with SDN skills and know-how. To keep competitive and relevant in the networking industry job market, you need SDN skills. ONUG Academy offers five tutorials taught by the experts who are deploying and developing open networking/SDN standards plus technology, including:
T1: Understanding and Deploying Virtual Networks by: Srini Seetharaman, Technical Lead for SDN at Deutsche Telecom
T2: Getting Started with OpenFlow Deployments by: Brent Salisbury, University of Kentucky
T3: Integrating OpenFlow and OpenStack by: Rob Sherwood, Open Networking Foundation Chair of Architecture and Framework Working Group
T4: Understanding White Box Networking Architecture and Economics by: JR Rivers, Co-Founder and CEO of Cumulus Networks
T5: Writing SDN Applications on Popular Controllers by: Matt Davy and Chuck Black, Tallac Networks
These tutorials and instructors were defined and handpicked by the ONUG Board, respectively, who are sending their networking, virtualization and DevOps teams, so should you. Here’s a 3-minute video on why you should enroll in ONUG Academy.
Pablo Espinosa, Director of Data, Video and Voice Network Infrastructure at GAP Inc plus ONUG founding member shares his hope of what Software-Defined Networking will enable at GAP Inc via video with the IT executives at the first Open Networking User Group or ONUG. Northbound APIs need to unlock automated orchestration, idle server and network capacity needs to be accessed and put to work and network configuration needs automation.
At Ixia’s iSimCity I sat down with Renuke Mandis, Technical Marketing Engineer at Extreme Networks to discuss the problem of VM moves not only between racks, but also between Layer 3 boundaries, which is a much harder problem to solve. Extreme Networks demonstrates how to extend VMs across Layer 3 boundaries using VPLS.
At Ixia’s iSimCity I sat down with Michael Francini, System Engineer/Technical Marketing Engineer at Arista Networks to discuss the problem of VMs joining, moving and being deleted from an Ethernet fabric. Michael demonstrates how Arista’s VM Tracer interacts with VMware’s Vcenter to provide administrative views to both network and virtualization operations groups and most importantly auto provision Arista’s Software-Defined Cloud Network to support VM joins, moves and deletes.
To show how Avaya’s VENA supports VM dynamics we demonstrate Avaya’s Virtualization Provisioning Service management tool that integrates into VMware’s vCenter to provide an end-to-end view of the virtualized Data Center, including VMs, physical hosts, and network devices across both physical and virtual environments. We put this to the test at iSimCity and with the help of Jeff Cox Solutions Architect and Elmer Balino Product Verification Test Engineer at Avaya. The goal is measure the level of difficulty to join, move and remove VMs from the Avaya VENA fabric.
At Ixia’s iSimCity we test Brocade’s VCS for the level of ease associated with how the VCS fabric supports virtualized data centers with Viral Vimawala Brocade, Technical Marketing Engineer. Thanks to VCS’s distributed intelligence VM moves are easily supported with the fabric providing auto-provisioning to support the new VM location.
At Ixia’s iSimCity I sat down with Jeff Cox Solutions Architect from Avaya to discuss Avaya’s approach to Ethernet Fabric design with its Fabric Connect solution. We were testing Avaya’s VSP 7000 Top-of-Rack Switch for the Data Center, in the industry’s first test of Ethernet Fabric technologies.
Nick Lippis describes the Layer 1, 2 and 3 multipathing test created to demonstrate Brocade VCS’s ability to join a switch into a fabric, create a trunk by simply connecting switches with multiple cables, evenly distributed hashing between a large number of links in a LAG and how multiple layer 3 gateways evenly share traffic load for layer 2 extension. These sets of test are the most telling about how easy it truly is to build a Brocade VCS fabric. Jeevan Sharma Manager Technical of Marketing at Brocade joins Nick Lippis as they dive into Brocade’s Active-Active feature set.
