PCT No. PCT/GB94/02648 Sec. 371 Date Nov. 14, 1996 Sec. 102(e) Date Nov. 14, 1996 PCT Filed Dec. 2, 1994 PCT Pub. No. WO95/17061 PCT Pub. Date Jun. 22, 1995A method of controlling acceptance of a call by a network node in a communication network having a required quality of service includes the steps of determining an infimum of a function of the probability of the node being overloaded if the call if accepted and determining from that infimum the effective bandwidth of the calls to the node if that call should be accepted and determining a corresponding quality of service. The corresponding quality of service is then compared with a quality of service that is required for satisfactory operation of the network. If the quality if maintained or exceeded then the call is accepted for the node.
