嵌入网SCP过载控制模型与算法的研究

Study on Overload Control Model and Algorithm for SCP in Embed Intelligent Network

嵌入网的SSP是设在端局,其业务流量比较大.在嵌入网中直接使用为叠加网设计的SCP过载控制算法会由于部分SSP过载而使SCP过载控制算法的性能下降.针对这种情况,首先定义了一种嵌入网的排队模型,然后根据这个排队模型设计了一种基于网络的SCP过载控制模型和算法.理论分析和实验结果表明该算法能够有效地对SCP和SSP的过载进行控制.

The SSPs of embed Intelligent network （EIN） are placed in local telecom office with tremendous service flow. If we use the overload control algorithm of SCP designed for OIN in EIN directly, it will cause partial SSP in EIN overload, and bring down the overload control algorithm of SCP＇ s performance. After defining a queue model of IN, this paper brings forward a model and an algorithm of overload control for EIN based on network. The theoretical analysis and experiment prove that it can efficiently prevent SCP and SSP from overload.
