Why Monitor Video Services?
Video service delivery validation & troubleshooting
End users associate poor video quality with poor network service
– Validation via monitoring will lead to earlier identification of issues and greater confidence in network
– Video is sensitive: early detection of network issues that may affect all traffic
Network may not be the problem!
– PC/mobile device based applications
Contractual SLAs need to be validated
– Violations may incur punitive costs

Dedicated Protocol Analyzers
Wireshark and other protocol analyzers are great – Detailed analysis for variety of protocols at deep level
Dedicated probes are expensive to deploy pervasively – Operator has to make difficult judgment calls on where the problem is going to be– before it
happens
Can be challenging after the fact- need on-site trained personnel.

Dynamic Monitoring with Mediatrace
Mediatrace discovers and queries L2 and L3 nodes along a flow’s path
Gathers system resource, interface and flow specific (perf-mon) stats – For performance monitor: dynamically configures monitoring policy (if needed) 5-tuple +
intervals etc. match static policy).
Consolidates information into a single screen
Allows for easy comparisons of device behavior – Which interface dropping packets? – Where is DSCP getting reset?
Can be requested by remote device
Automatically (based on thresholds) via EEM script
Let mediatrace do the walking for you!

MSI Management
MSI provides a REST-based API to manage endpoints that support MSI – http(s)://<IP>/msi/
Using this API, an authorized management station can: – query for device, user, flow metadata monitor performance
– Initiate mediatraces & results
– Subscribe to event and notifications
– Manage thresholds

But:
– IPSLA VO traffic is of type RTP, so can be analyzed by perf-mon
– perf-mon can be enabled by mediatrace to analyze RTP traffic
– mediatrace can perform fault-isolation on IPSLA VO traffic
– * Cisco Prime Collaboration Manager can run and visualize mediatrace on IPSLA VO traffic

4. Localize problem using Collab Manager and Mediatrace
