heal.abstract	The provision of novel multimedia services in broadband networks through intelligent network (IN) technology is a promising solution that guarantees fast deployment of new services and minimum changes to already operating networks. In this architecture, the broadband service control point (B-SCP) is the main actor in the processing of complex IN service requests. This centralized approach which is reflected in the multiplicity of tasks undertaken by the B-SCP in a broadband IN architecture, can easily lead to network performance degradation. Therefore, the presence of a congestion control mechanism operating at the level of calls is considered essential in order to protect the network nodes from overload conditions and to attain high levels of network performance. In this paper, we propose an adaptive congestion control mechanism (ACCM) which is able to guarantee the desirable quality of service under overload conditions. The proposed mechanism gradually reduces the message transmission rate from the source node to the destination node when overflow conditions have been detected, taking as feedback the buffer capacity state of the destination. Results, obtained by simulation show that the proposed ACCM improves the network performance by maximising the number of established calls and reducing the number of rejected calls.
