podcast_3_artworkIn 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?

podcast_2_artworkAs 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 Defines A Performance Management Layer

podcast_1_artworkNetScout’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 Systems Catalyst 6500 Sup2T VSS Throughput Performance

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.

Catalyst 6500 Sup2T Network Virtualization via MPLS/VPLS Performance

November 30th, 2011

Network virtualization, or the ability to divide a physical network into multiple logical networks with unique attributes, is a design that has grown in popularity as IT business leaders have sort ways to segment their network with different attributes for different user groups. This is popular in healthcare, education, travel and other industries. Network virtualization can be implemented either in IP, and/or MPLS. In addition connecting the Catalyst 6500 directly to service provider MPLS networks is another popular design; therefore we test throughput performance for both scenarios here.

For active-active data center operation, disaster planning and load balancing are best practices when connecting data centers via MPLS or VPLS. VPLS layer 2 connected data centers deliver LAN-like service over the campus and/or wide area network. Layer 2 connectivity is important as server-server communications expect layer 2 connectivity as most applications have been designed with this assumption. For connecting more than two data centers, VPLS offers mesh connectivity. Data centers connected via VPLS look and act as if they are on the same LAN. Therefore, we test that VPLS throughput performance rates are equally high performance in this scenario as MPLS.
