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.

Lippis Report 207: The Killer SDN Applications: Network Virtualization and Visualization

April 8th, 2013

nicklippis.jpgAt the last Open Networking User Group (ONUG) meeting in Boston organized with partner Fidelity Investments, it became very clear that there are two killer SDN applications: network virtualization and visualization. Some argue that network virtualization used for VM-VM networking is not an SDN technology, but I beg to differ. Sure, there are closed and open approaches to network virtualization, but over the next business cycle, the integration of OpenStack and OpenFlow will make it clear that network virtualization is an SDN application, especially as it’s extended to physical networks. The second killer app is network visualization—that is, the ability to monitor network traffic and tweak application performance.   At ONUG Rich Groves, Principal Architect at Microsoft presented his SDN based approach to network visualization he designed with Big Switch Networks, cPacket, IBM, Arista and other suppliers that everyone is now using.  Why is network visualization an SDN killer app? Because it uses SDN technology, and most importantly, lowers the capital cost significantly from existing network visualization approaches while also delivering an entirely new level of self-server flexibility. Companies, such as Big Switch Networks, Gigamon, Arista, Cisco, NetScout, Ixia/Anue, cPacket and others, are now positioning their network visualization offers within an SDN context and for good reason. In this Lippis Report Research Note, I focus on network visualization as an SDN killer app.
