This algorithm can be used for QoS-based route computaion for ATM PNNI and Internet protocols such as QoS OSPF. Acommunication network containing links with multiple QoS metrics is modeled as a graph with multiple weights associated with its edges. This method takes a metric(e. g. cost)as the optmization target and another metric(e. g. delay)as a constraint. This algorithm is guaranteed to find a nearly optimal path satisfying the given comstraint if such a path exists. The algorithm is very efficient and its computational complexity is O(n2).展开更多

The algorithm is OIL (Older Is Leader) algorithms for Peer Group selection, and the method is the DOO (Distributed object-oriented) method for HDOS (Hierarchy Distributed-Object System), PNNI systems and IP(Internet Protocol) networks. Based on the specifications from ATM forum, and the creative ideas from Distributed System realization, this paper studies and analyzes the private ATM network environment. The OIL algorithm and the DOO method are both for PNNI routing protocol. Through the PNNI simulation, the availability and robustness are proved for the above two improvements.展开更多

With the analysis of QoS service in ATM networks and broadband IP networks, it gave a requirement based strategy for QoS service application with Fuzzy language evaluation principles. The requirement parameters are chosen according to the WANT/COST rule, and a fuzzy set is constructed to realize the fuzzy determinant. The simulation results show that it is useful to evaluate the QoS service in broadband networks, and to effectively simplify the access protocols and solve the billing issues in broadband networks.展开更多
