Point to multi-point connection - forming virtual chain of connections in self-routing ATM coupling field

摘要

The method involves connecting signalling and data cells, including information to be transmitted, and a connection information preamble according to the ATM exchange principle. Transceivers (GP) are connected to the ATM field (ASN) via connector modules (KAM). One transceiver (GP0) broadcasts at least one signalling cell for carrying out connection to the other transceivers (GP1..GPn). Depending on the information in the cell, characteristic information for the connection routes is stored in two tables (TAB1, TAB2). The data cells from the first transceiver (GP0) are transmitted to the group of other transceivers (GP1..GPn). The data cells are duplicated in the first transceiver (GP1) of the group and are transmitted to successive transceivers in the group via the ATM coupling field (ASN). This process is continued through the transceivers until the last transceiver (GPn) in the group is reached. ADVANTAGE - Carries out connections without limiting system dynamics. Connection route information, also at end of virtual chain kept to minimum.
