Recommendation ITU-T H.248.64 has in scope ITU-T H.248 media gateways with connection models using only IP-based ITU-T H.248 streams/terminations. The different modes of IP packet forwarding (in the ITU-T H.248 bearer path) are described. This Recommendation further defines an ITU-T H.248 package for discriminating such modes and protocol elements for the so-called IP router forwarding method. Further ITU-T H.248 packages provide capabilities for service enhanced packet forwarding with respect to the support of additional network address translation.
