Abstract
A method of detecting proximity between a media proxy and a client uses a proximity probe to query a plurality of media proxies, forcing the media proxies to respond to a proximity server. The proximity server uses an algorithm to determine which media proxy is closest to the client based on the responses. In an alternate embodiment, the same sorts of proximity probes may be used to determine if two media endpoints have a direct connection such that they may bypass a media proxy.
