Summary

Recommendation ITU-T Y.2082 specifies the architecture for relay function (RF), in support of application layer routing optimization for performance improvement and network address translation (NAT)/firewall traversal in the environment of distributed service networking (DSN) as described in Recommendation ITU-T Y.2080.

Application layer routing optimization means the usage of application layer relays to change the route of data packets. Considering the case that the default transport layer route is congested, better performance can be achieved through application layer routing optimization.

The main objectives of this Recommendation are to specify:

������������ Functional entities of RF

������������ Information flows related to RF

������������ Reference points related to RF.
