The invention relates to Connection Admission Control (CAC). In response to a connection request received from a traffic source, a set of input data is specified and when necessary a set of results is calculated by means of the input data. A total capacity requirement is then estimated on the basis of said set of results and the capacity requirement of existing connections. In order to obtain a connection admission control which can be flexibly adapted to the various constantly changing network environments, the sets of input data and the corresponding sets of results relating to previous requests are stored in a cache. When a new connection request arrives, a similar set of data is searched for in the cache. When it is found, the stored set of results is used directly for estimating the total capacity, and the calculation is omitted. |
