<p>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.</p> |
