Network service header (NSH) metadata-based end-to-end multimedia session identification and multimedia service optimization

摘要

A classifier node in a service function chaining system receives a media stream from an endpoint device. The media stream is associated with a media session between the endpoint and at least one other endpoint. The classifier node determines a service function path for the media stream. The service function path includes an ordered list of service functions to process the media stream. The classifier node determines a session identifier for the media stream and encapsulates the media stream with a Network Service Header. The Network Service Header includes an indication of the service function path and a metadata header with the session identifier.
