METHOD AND METHOD FOR MULTIPLEXING A FRAME, RELAY SYSTEM, AND FRAME-RELAY SYSTEM HAVING MULTIPLEXED VIRTUAL CIRCUITS FOR PROVIDING INTEGRATED DATA MANAGEMENT

摘要

There is provided a multiplex transmission line and method for providing thorough data management through a single frame trunk line of a relay network using a frame relay network capable of relaying frames having associated flags. This circuit includes (1) a logical channel generation line for designating first and second headers to be associated with each relayed frame via a channel flag and a first and a second logical channel over a single frame relay virtual circuit, and ) Inserts a channel flag and a second header in each frame of the second data stream that coincides with the channel flags and inserts the first header only in the frame of the first data stream so that the first and second logical channels And a multiplexer for associating the frames of the first and second data streams with the first and second logical channels, respectively, which can be multiplexed via a single frame relay virtual circuit, wherein one of the frames of the first data stream The frame does not reduce the overhead of the multiplexed transmission line to the first header.
