Separation of Control and User Plane for Proxy Mobile IPv6
RFC 7389, “Separation of Control and User Plane for Proxy Mobile IPv6”, is a Proposed Standard document published in October 2014 by R. Wakikawa, R. Pazhyannur, S. Gundavelli, C. Perkins. The canonical text is published by the RFC Editor.
Abstract
This document specifies a method to split the control plane (CP) and user plane (UP) for a network infrastructure based on Proxy Mobile IPv6 (PMIPv6). Existing specifications allow a mobile access gateway (MAG) to separate its control and user plane using the Alternate Care-of Address mobility option for IPv6 or Alternate IPv4 Care-of Address option for IPv4. However, the current specification does not provide any mechanism allowing the local mobility anchor (LMA) to perform an analogous functional split. To remedy that shortcoming, this document specifies a mobility option enabling an LMA to provide an alternate LMA address to be used for the bidirectional user-plane traffic between the MAG and LMA. With this new option, an LMA will be able to use an IP address for its user plane that is different than the IP address used for the control plane.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
