User satisfaction is the ultimate metric for performance evaluation of rich media services. The only way to be sure of delivering highest quality of experience is by actually measuring quality of experience. Therefore, it is not surprising that most IT managers identify application performance as their single most critical problem.
Many traditional performance monitoring solutions are delivered as appliances. Although an increasing number of solutions are deployed on virtual machines or in some cases cloud offerings are available, there are nevertheless ongoing administrative overhead. Monitoring is best done pervasively unless you already know in advance where all the problems are going to be. Deploying these traditional monitoring solutions typically only provide partial view as it is not possible to deploy probes everywhere.
With IOS Performance Monitor, first made available in IOS 15.1(3)T, we introduced a new innovative approach to performance monitoring. A Cisco network element is embedded with native monitoring capabilities. It can collect packet loss, jitter, delay and response time information for performance evaluation of data, voice and video services. This approach effectively turns every network element as probe providing the most extensive visibility because all the flows must go through the network. This approach eliminates the need for deploying flow data collection solutions external to the network devices which would lead to increased costs for data collection and operation expense. Now, network managers can continue to leverage their Cisco IP network assets, resulting in substantial savings.

In the first part of this blog we discussed the transition from unified communications to pervasive video and the use of service discovery mechanisms and auto-registration.
Over time, the use of service discovery and registration protocols will become pervasive across rich media endpoints to simplify and automate deployment. It provides the foundation by which applications can then automate other aspects of configuration on the endpoints. One example would be to have a set top box not only automatically discover and register to its nearest content server but also to provide other information such as location to enable the automatic selection and streaming of the right content for that particular set top box. Network service discovery and registration provides the basic infrastructure to enable a fully automated application deployment; achieving true plug and play deployment.

We’re already seeing the beginnings of the transition from unified communications to pervasive video. Companies are not only starting to leverage video to enhance their communication experience but also they are finding new and innovative ways to leverage video to improve business operation and improve customer interaction. You only have to walk into a retail store or get on public transport to see video being used at the heart of the customer experience. As video becomes more ubiquitous this will drive two trends that impact how video endpoints and applications are deployed.
The first is the need to simplify deployment of those IP enabled endpoints. Deploying large numbers of video endpoints, often in a diverse range of locations and by personnel who are not skilled in IT and network deployment. We’ve already seen enhancements in earlier versions of medianets that enable devices such as surveillance cameras and digital media players that enable the installer to plug the devices in and have the network configuration automatically applied to the switch port. This simplifies the network configuration but challenges still remain in configuring the endpoint or application to connect to and register to application services. To address this issue, there are a number of service discovery mechanisms that can enable a newly deployed endpoint or application to automatically discover and register to its application server.

It’s been a few weeks from this year’s US Cisco Live event, and we are energized from the excitement and resonance from our partners and customers. Also a little bit exhausted (see what was going on).
This year we saw the build out of the visibility pillar of the medianet architecture. With features like performance monitor, mediatrace, and IPSLA Video Operation, we have added very powerful tools existing cisco tool chest (think regular IPSLA, NetFlow, etc.) to aid in the deployment and maintenance of rich media applications. There were also a number of management solutions from our CDN partners (CA Technologies, Cisco, SevOne, ActionPacked and Plixer) ready to exploit these features.
The week started on Thursday night (4 days before the event) with the enablement of the cat3750s and ISRs in the Cisco Live production network with the mediatrace and performance monitor feature. There were a number of media endpoints in the network this year ranging from IP Video Surveillance Cameras, IP phones, to Cisco TelePresence equipment. In fact, the Cisco TelePresence Content Server (TCS) was performing a pilot at cisco live where 46 sessions were recorded leading to 111 GB of video content. Medianet performance monitor was monitoring the audio and video traffic generated from the C90 and stored at the TCS. The video surveillance setup consisted of over 50 cameras (HD and SD) storing over 10 terabytes of data. Medianet performance monitor was also analyzing the video traffic here for anomalies. Fortunately, nothing bad occurred on this portion of the network but we were ready to identify and fix it quickly!
