Abstract
Various methods and apparatus are directed to, among other things, an access node which is used in providing enhanced functionality and fault tolerance in a system which distributes home agent functionality between a home agent control node and a tunneling node, referred to herein as a home agent tunneling node, which performs packet forwarding under direction of the home agent control node. The distributed home agent approach is enhanced in some embodiments to provide redundancy of home agent control nodes and/or home agent tunneling nodes. Thus, in accordance with some embodiments if a home agent control node fails, the secondary home agent control node can take over the home agent control function. Various embodiments describe various methods, apparatus, and/or messages in addition to system configurations, which can be used to maintain primary and secondary home agent control and facilitate a rapid transfer of functions between primary and secondary nodes.
