Abstract

An ATM communication system having DBA, comprising storage means for DBA traffic, which storage means includes dedicated storage means for ABR traffic, the system being such that ABR bandwidth requests are allocated after all other DBA
bandwidth allocations have been satisfied, means being provided for interrupting an ABR transmission, before a bandwidth allocation within which the said ABR transmission is included has been fully used, for the transmission of other higher priority DBA traffic.
