Arrangement for regulating traffic in a high speed data network.

摘要

The invention relates to methods and apparatus for regulating traffic in a Broadband Integrated Services Digital Network (B-ISDN) 30. Terminal adapters 20,21 interface between terminals 10,11 and the B-ISDN 30. Whenever a first terminal 10 wishes to transmit a data message to a second terminal 11, the source adapter 20, connected to the first terminal, allocates transmit bandwidth for the transmission of the message and sends a request message to a destination adapter 21, 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.
