Recommendation ITU-T Y.2082 specifies the architecture for relay functions (RF), in support of application layer routing optimization for performance improvement and NAT/Firewall traversal in the environment of 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 compared to default transport layer route.
The main objective of this Recommendation is to specify
Functional entities of RF.
Information flows related to RF.
Reference points related to RF.
