Two network entities allocate the performance of encryption and compression algorithms amongst each other in a controlled and coordinated manner so as to avoid unnecessary duplication of encryption and compression at different protocol layers and an associated waste of CPU power. For example, a first network entity performs both encryption and compression at the IP layer, and instructs the second network entity to disable PPP-layer encryption and compression. In a wireless networking example of the invention, the first network entity is a home agent (e.g., a router) for a wireless communications device and the second network entity is a foreign agent (e.g., a network access server) providing network access for the communications device. The foreign agent terminates a Point-to-Point Protocol (PPP) session with the communications device, but implements (or does not implement) PPP-layer compression and encryption algorithms under the supervision and control of the home agent.
A method of controlling compression of data exchanged between two different network entities and a communications device, wherein said two different network entities comprise a first network entity and a second network entity comprising a foreign agent for said communications device, wherein said first network entity and said foreign agent comprise a processing unit capable of performing at least one data compression algorithm on said data, the method comprising the steps of:
A method of controlling encryption of data exchanged between two different network entities and a communications device, wherein said two different network entities comprise a first network entity and a second network entity comprising a foreign agent for said communications device, wherein said first network entity and said foreign agent comprise a processing unit capable of performing at least one encryption algorithm on said data, the method comprising the steps of:
A method for controlling implementation of Internet Protocol (IP) and Point-to-Point Protocol (PPP) encryption and compression algorithms, the method implemented in a system comprising a home agent and a foreign agent coupled to a network and terminating a PPP session with a communications device over said network, comprising the steps of:
