Abstract
The invention relates to methods and apparatus for regulating traffic in a Broadband Integrated Services Digital Network (B-ISDN). Terminal adapters interface between terminals and the B-ISDN. Whenever a first terminal wishes to transmit a data message to a second terminal, the source adapter, connected to the first terminal, allocates transmit bandwidth for the transmission of the message and sends a request message to a destination adapter, connected to the second terminal, for checking availability of and allocating receive bandwidth. The data message is sent only if bandwidth has been allocated on both ends. Overflow traffic is throttled at the adapters before it enters the network, thereby reducing the number of data cells lost because of the limited storage of the network.
