Title:
PROXY, SESSION KEEP ALIVE DETECTION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2009/024098
Kind Code:
A1
Abstract:
A proxy is provided, which includes: session keep alive detection conversion
processing unit, for conversion between the first session keep alive detection
supported by the first session communication peer and the second session keep
alive detection supported by the second session communication peer. Another
proxy is also provided, which includes session group keep alive detection processing
unit, for being middle proxy of session group keep alive detection between session
group communication peer and session communication peer. Accordingly, the
session keep alive detection method and system based on two proxies are also provided.
The conversion between different session keep alive detection mechanisms is
realized, and the execution of session group keep alive detection decreases
the packet communication flows in session keep alive detection.
