ABSTRACT:
A system and associated method for optimizing media data in signaling stream of a network system. A client subscribed for a presence service sends a signaling message embedding media data in an Extensible Markup Language file. An optimizer gateway in the network system intercepts the signaling message, extracts and keeps the media data, replaces the media data in the signaling message with a reference pointer to the media data, asynchronously processes the media data, retransmits the media data to another client subscribing to the presence service, or reinstate the media data from the reference pointer to the media data.
