Protocol for Forwarding Policy Configuration (FPC) in DMM
draft-ietf-dmm-fpc-cpdp-02.txt
Abstract
This specification supports the separation of the Control-Plane for
mobility- and session management from the Data-Plane. The protocol
semantics abstract the configuration of Data-Plane nodes and applies
it between a Client function, which is used by an application of the
mobility Control-Plane, and an Agent function, which is associated
with the configuration of Data-Plane nodes, according to the Data-
Plane rules issued by the mobility Control-Plane. The scope of the
rules comprises traffic description and treatment of packets in terms
of encapsulation, IP address re-writing and QoS. Additional protocol
semantics are described to support the maintenance of the Data-Plane
path.
