IOS Performance Monitor – A powerful tool for negotiating SLA with your Service Provider
The only way to be sure of delivering highest quality of experience is by actually measuring QoE of real traffic. In IOS 15.1.3T, we introduced a new embedded monitoring capability to collect packet loss, jitter, delay and response time information for performance evaluation of data, voice and video services. The feature is called IOS Performance Monitor. (See yesterday’s blog on User Traffic Analysis by Medianet performance Monitor.)
In December of last year, Cisco IT was running a medianet pilot program for the new IOS performance monitor feature as their ongoing effort to provide high quality and improved services to end users. The pilot was designed to support 50 remote sites equipped with the ISR-891 routers. Two of the pilot sites were small Cisco offices and the remaining was home offices. I was lucky enough to be selected for the pilot.
The IOS Performance Monitor feature was enabled on the ISR-891 router. It was configured to monitor voice, WebEx (data, voice & video), Movi desktop video and Tandberg videoconferencing traffic. After two weeks of continuous monitoring, I was told by Cisco IT that I do not have a reliable internet service provider. Consistently, I was experiencing 10% of packet loss. Sometimes I wondered why I was not heard on the phone. I was never happy with my internet provider but for the first time, I have proof. Armed with this new data, I’m determined to ask for 10% rebate from my internet provider since they were dropping 10% of the packets anyway. Wish me luck!
I realized as a result of this pilot that the Performance Monitor capability could be a powerful tool for enterprises to negotiate their service level agreements with their service providers. The capability provides visibility into the network and measures their SLA with the Service Provider.
