LOGIC LINK CONNECTION SERVER

摘要

PROBLEM TO BE SOLVED: To switch an ATM connection of an ATM adaptive layer AAL-2 packet to other ATM connection in a sub ATM cell level such as logic link connection(LLC) by bundling again the ATM adaptive layer AAL-2 packet in the case that a plurality of sources and a destination are included in connection among a plurality of termination nodes. SOLUTION: An LLC server 200 bundles again two LLC packets according to two transfer tables each denoting each direction of communication and the packets are divided into two, which arrives at an adaptor TAB205 and outputs from an adaptor TAS215. Each column of the transfer tables maps a specific virtual channel connector(VCC) and a CID through a specific port to a channel IDCID in VCC, then the LLC server 200 bundles again a payload of the LLC packet arrived in the TAS205 into a new LLC packet with a new CID and gives the new LLC packet to a proper port on a designated VCC to switch the packets.
