ABSTRACT:
When bandwidth in an ATM network is controlled so as to increase in accordance with a user request, there is a considerable delay from the occurrence of the request until the bandwidth is actually changed; and there is therefore a need to control the traffic flowing in ATM network transmission paths faster and more flexibly. There is also a need to decrease the probability of overbooking occurring when deciding whether or not to accept a bandwidth change request. Route information that includes information relating to residual bandwidth is therefore collected in advance by subscriber switches that serve terminals. In response to a request from a user, a subscriber switch alone replies rapidly. During this process, the fact that there are a plurality of bandwidth change requests within the same residual bandwidth measurement period, is considered and a portion of the measured residual bandwidth is held for other bandwidth change requests. This enables the delay to be shortened. In addition, it is sufficient if the functions corresponding to the plurality of protocols employed by users are provided at and only at the subscriber switches which directly serve those users, whereby the hardware configuration of the transit switches etc. can be simplified. In addition, bandwidth can be allocated with high precision.
