System and method for traversing metadata across multiple network domains at various layers of the protocol stack

摘要

An inter-networking system and method that provides for access control identifier (ACI) metadata utilization for the life of a session even on unknown networks being traversed, allowing for ACI metadata utilization, reutilization, and modification in both the send and receive paths (bi-directional), and allowing for metadata transport over network segments requiring that ACIs be embedded at different layers of the communications stack.
