IP SLA Video Operation – A powerful tool to mimic the real traffic demands on your network

With video increasingly becoming part of how you collaborate, you need to consider the impact of this incremental video on your network. Video brings many new challenges in order to meet user expectations for a flawless quality of experience. So is your network ready for rich media?

IP SLA video operation answers this question by synthetically generating traffic  mimicking real application traffic. The ability to generate realistic RTP stream similar to real life Cisco TelePresence allow you to stress the network and assess the demands these applications will impose on your network. Each type of media application can be expressed for the synthetic media generation system by media application profiles that contain personalities which incorporate characteristics such as bit rate, burst sizes, inter-packet-gaps, etc. These application profiles allow, for example, a catalyst switch to simulate the video playout from multiple places in the network. There may be multiple personalities based on different software versions or configurations of the media application. Cisco will make a set of comprehensive media application profiles available for download. IP SLA video operation, an enhancement to IP SLA, was announced on April 6, 2011 at ISC West in Las Vegas and is first introduced in IOS 12.2(58) SE on Cisco Catalyst 3750 and 3560 series switches. Over time, more products will be implementing this new operation.

The foundation of an effective video experience is the converged network which must deliver consistent quality to achieve seamless quality of experience. It is a critical first step to perform the up-front assessment to establish a baseline for successful rich media  deployment. IP SLA video operation is a useful tool for network readiness assessment. Next week, we will share with you different scenarios how a network operator uses the tool.
