Abstract The dependence is formed between different function entities due to service request. The concept named “adjacent resources” is proposed according to the dependence and the NGN’s flatter architecture than the traditional telecommunication network. A distributed algorithm for overload control is presented, which is based on the proposed concept. It throttles the request at the logical adjacent resources. The algorithm can effectively handle with the overload control issuing from SIP fork or load balance scenarios. The mechanism can improve the network effective throughput by throttling the service request as soon as possible, which satisfies with the overload control requirements presented in the ETSI TISPAN draft.
