Abstract:
1. A method of carrying out connection admission control in a communications network, the method comprising the steps of receiving connection requests from traffic sources, in response to a connection request received from a traffic source, determining a request-specific set of input data, calculating a set of results by means of said set of input data, said set of results indicating a capacity requirement of said traffic source, estimating a total capacity requirement on the basis of said set of results and the capacity requirement of existing connections, and deciding on the acceptability of said connection request on the basis of the estimated total capacity requirement, wherein the method further includes the steps of in response to said calculation, storing said set of input data and the corresponding set of results into a cache, in response to said determination, searching in the cache for a set of data similar to the request-specific set of input data, and using the stored set of results for estimating the total capacity when a similar set of data is found from the cache, whereby the calculation of the set of results is omitted when a similar set of data is found.
