Medianet Media Awareness enables the network to become application and rich-media context aware end to end. Media Services Proxy is one of the techniques to detect different types of endpoints, media and application types (Telepresence, video surveillance, desktop collaboration and streaming media) in order to deliver the best experience.
Media Services Proxy Components
Media Services Proxy, an IOS technology, uses light weight deep packet inspection techniques to snoop standard based signaling protocols. It uses a variety of standard signaling protocols (SDP, H.323, H.245, RTSP, mDNS, etc.) to learn about the characteristics of endpoints and applications from legacy systems.
Once the endpoints and application types are known, MSP can apply a number of services on behalf of the endpoints and flows. For example, MSP detects a video surveillance camera, it applies Auto Smartports by automatically configuring the switch port for a camera to significantly simplify deployment. When MSP detects the flow type, it can apply QoS or bandwidth reservation on behalf of the flow. More importantly, MSP can share flow attributes amongst network nodes thereby allowing policies to be applied end to end.
Where to find Media Services Proxy today
Media Services Proxy is best positioned at user edge (e.g. access switch) and resources edge (e.g. internet edge). MSP is first introduced in IOS 03.03.00.SG.151-1.SG on Cisco Catalyst 4000 series switches and in IOS 15.2(3)T on ISR-G2 routers. Over time, more products will be implementing Media Services Proxy.
