공통선 신호방식에서의 DAR(Dynamic Adaptive Routing)방식과 FSR(Flood Search Routing)방식의 성능평가

Performance Evaluation of DAR(Dynamic Adaptive Routing) and FSR(Flood Search Routing) Methods in a Common Channel Signaling Scheme

In this paper, we hve compare the performance of DAR(Dynamic Adaptive Routing) with that of FSR(Flooding Search Routing) to select an adequate routing protocol in circuit-switched networs. As a performance factor, we have considered call setup time, which is the key factor of performance evaluation in circuit switched networks. We have evaluated the performance of two methods in grid topology circuit-switched networks using a commn channel signaling scheme, as application examples. As results, FSR method shows better performance than DAR method under light traffic load, when the number of links by which call has passed increases, but DAR method represents better performance than FSR method under heavy traffic load or large networks because of redundant packets.
