Abstract

See full text

This invention relates to a method and system for a collision free insertion and removal of circuit-switched channels in a self-adaptive transmission data structure carrying different classes of packet-switched traffic on a slotted Local Area Network (LAN). This network may have bus or ring topology. The different classes of traffic are asynchronous traffic (packet-switched), synchronous traffic (packet-switched, time sensitive), isochronous traffic (circuit-switched), and signalling on demand. The inventive self-adaptive transmission data structure permits an economic, flexible and bandwidth efficient integration of these different classes of traffic.
