Abstract

A packet multiplexer capable of realizing the optimization of a communication path automatically, without requiring a user to explicitly specify for it, is disclosed. The packet multiplexer is formed by a plurality of first communication interfaces for terminating a plurality of C-plane and U-plane pairs on one side of the packet multiplexer, a second communication interface for terminating a single C-plane and a plurality of U-planes on another side of the packet multiplexer, a connection interface for multiplexing the C-plane and U-plane pairs terminated at the first communication interfaces into the single C-plane and the plurality of U-planes terminated at the second communication interface, and a control unit for controlling multiplexing of U-planes by the connection interface according to signaling through C-planes, such that a cut-through is made within the packet multiplexer between two U-planes terminated at the first communication interfaces that form a loop.
