Method to provide dynamic internet protocol security policy service

摘要

A mobile node may roam away from its home network to a foreign network. The mobile node may communicate using the Mobile Internet Protocol, and it may use Internet Protocol security to communicate with its home network. A foreign agent on the foreign network and a home agent on the home network may dynamically link a policy to be used for a Internet Protocol security session between the foreign agent and the home agent. The foreign agent and the home agent may dynamically create a filter to be used for the Internet Protocol Security session.
