Description / Abstract:

In scope of this Recommendation are ITU-T H.248 IP media gateway TCP-based bearer interfaces. Such an ITU-T H.248 MG provides various functions for processing of TCP/IP packets, TCP payload data and is involved in functions related to TCP protocol control information (based on TCP header flags). This Recommendation focuses primarily on the aspect of TCP connection control, which comprises the establishment and release of TCP bearer connections.

The Recommendation considers: – connection models with a single or multiple TCP bearer connection endpoints within an ITU-T H.248 context;

– establishment, through-connection and release behaviour in case of end-to-end TCP bearer connections across two ITU-T H.248 TCP terminations ("a so-called ITU-T H.248 TCP media stream");

– different ITU-T H.248 control models.

Further, this Recommendation provides information on existing ITU-T H.248 tools with respect to other TCP support functions.
