Communication network control method and apparatus
First Claim
1. Apparatus for controlling acceptance of a call from a first network node to a second network node over a transmission path between the nodes, said apparatus comprising:
- memory for holding a database of activity distributions for particular classes of calls;
means for classifying the call;
means for selecting from the database a distribution appropriate to that class;
means for determining a current load on the transmission path due to calls of that class;
means for generating a posterior activity distribution from the selected distribution and current load; and
means to reject or accept the call on the basis of the posterior distribution.

Abstract
A communication network includes a number of network nodes linked together by transmission paths. A network manager controls acceptance of calls onto transmission paths by classifying an incoming call and selecting from the database an appropriate mean to peak bit rate distribution. This selected distribution is then used with the monitored transmission path load to determine a posterior distribution which reflects the load. The decision to accept or reject the call is made on the basis of the posterior distribution by a call acceptance algorithm considering the effective bandwidth for example.
