Abstract
The present invention concerns a transmission bandwidth sharing system and provides, in particular, a transmission bandwidth sharing apparatus used in an ATM exchange for sharing one CBR bandwidth on an ATM line among a plurality of ATM terminals in a multimedia network or the like. The CBR bandwidth sharing apparatus comprises a bandwidth management table for registering bandwidth and information relating to the bandwidth for each identified CBR bandwidth, a bandwidth sharing management table for registering, for each identified CBR bandwidth, one or more terminals that use the bandwidth for CBR communication and information relating to the one or more terminals, and a signal transmission timing management table for registering valid signal transmission timings of the registered terminals for each identified CBR bandwidth. Based on the bandwidth information and terminal information, the CBR bandwidth sharing apparatus allocates a timing in an invalid signal transmission period of one of the registered terminals for use as a transmission timing of a valid signal from another one of the registered terminals, thereby enabling a plurality of CBR communication connections to be established by sharing the identified one CBR bandwidth.
