Routing Packet Flows Along An Optimized Path

摘要

Routing a packet flow in a communication session includes facilitating a communication session between a first endpoint and a second endpoint. A packet flow from the first endpoint is received at a transient anchor of a visited network. The transient anchor establishes whether the packet flow is to be routed along an optimized path according to one or more routing rules. The packet flow is sent to the second endpoint if the packet flow is to be routed along the optimized path. The packet flow is forwarded to a permanent anchor of a home network if the packet flow is not to be routed along the optimized path.
