Explanation

Media Services Proxy (MSP) uses a variety of standard signaling protocols (Session Description Protocol [SDP], Session Initiation Protocol [SIP], H.323, H.245, Real Time Streaming Protocol [RTSP], multicast DNS [mDNS], etc.) to learn about the characteristics of endpoints and applications from legacy systems, allowing sharing of flow attributes among network nodes and allowing existing endpoints and applications to be augmented by the Cisco intelligent network while the transition to "smart" endpoints is in progress. MSP is a software feature available in Cisco IOS Software recommended to be positioned at the network access layer. When endpoints establish audio and video calls, the MSP identifies theendpoint attributes by sniffing the signaling and associating these attributes with the endpoint. It then provides services on behalf of the endpoint; for instance, generation of metadata, that can be used by downstream network nodes. medianet/solution_overview_c22-654289.html
