SYSTEM AND METHODS FOR COMPRESSING MESSAGE HEADERS

摘要

An MPLS router operable for labeled switch path (LSP) operation defines a compression index for identifying a decompression context between other MPLS LSP routers. The compression index allows a multipoint-to-point link between MPLS routers, thereby avoiding an exhaustive mesh of point-to-point links between each of the MPLS routers. The originator ID identifies each of the multipoint originating endpoints at a common destination, and maintains the context of each compressed header to match incoming compressed headers to the corresponding header values. The originator ID, typically the IP address of the originator, operates as the compression index on the multipoint-to-point connection, operable to distinguish multiple originators of the multipoint-to-point connection and provide header compression for each.
