A method, a unit and a computer program product for providing topology awareness information within an IP network includes a central node and a plurality of routers, wherein the probe is implemented in a router within the IP network and the probe belongs to a topology awareness system, that includes: elements for obtaining and maintaining relationship with other probes within the IP network, elements for collecting information about other network elements e.g. routers and switches, elements for communicating topology information with the central node of the topology awareness system, and elements for obtaining information concerning local resources on the router where the probe is implemented.

Method for providing topology awareness information within an IP network

A system, method, and apparatus for increasing the efficiency of the compression of a communication protocol for use over bandwidth limited communication links. One aspect of the present invention provides for the sharing of context information between a compressor and decompressor at each communication entity in a communication system. As a result, context information will be shared for each channel pair. In another aspect of the present invention, multiple communication sessions between communication entities may share the same context information for the compression and decompression of communication messages.
