The Problems in QoS Routing
QoS中的路由问题

The next-greneration high-speed networks are expected to suppot a wide range of delay-sensitive multimedia applications. They need a different routing algorithm from the conventional one. The goal of the new algorithm is twofold: (1)satisfying the QoS requirements for every admitted connections,and(2)achieving global efficiency in resource utilization. Thus,most of problems in QoS routing area have multiple constraints which make them NP-Hard. Until now,the generally effcient algorithm has not been found. In this paper,we pose two algorithms for PCPO problems common in QoS communication,and analyze respective characteristics and uses.
