IP SLA Video Operation Part 2 – How to use it? When to use it?

Last week, we introduced the new IP SLA Video Operation tool to assess the readiness of a network by generating synthetic traffic to mimic real applications. When you use IP SLA VO to generate simulated RTP traffic between two sites, you can use the medianet Performance Monitor feature to measure the performance of this synthetic traffic across the network. You can also use Mediatrace to discover the network elements on the paths between the two sites. For each network element discovered in the network path, Performance Monitor can collect metrics to detect potential capacity bottlenecks and proactively identify quality issues.

In addition to the obvious use for pre-deployment assessment, many enterprises understand that the network and applications are constantly changing so it is necessary to do continuous assessments. For example, after a major scheduled network maintenance or upgrade during non-business hours, you can use IP SLA VO to simulate real application traffic and assess the impact of the network changes to minimize potential business disruption or even downtime. Another example is prior to an important event, you can use IP SLA VO to stress test the network and verify that it can handle the rich media traffic without impacting existing application performance.

Whether you are doing an initial assessment for a new deployment, an expansion to an existing deployment, or ongoing operations, IPSLA VO, Performance Monitor and Mediatrace are effective tools to identify and proactively resolve rich media problems across the  network. Put this handy tool in your toolbox and you will like it.

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.
