摘　　要：通过考察QoS需求和网络路由之间的相互关系,发现满足各种不同QoS业务传输需求的先决条件是网络需要提供可以实现并发分流传输的差异化的传输资源。当前网络采用的单下一跳路由机制只能提供单一的传输资源,两者之间存在不可调和的矛盾。这是制约当前各种QoS方案通用化的根据原因。结合多下一跳路由可提供大量并行传输资源的先决条件,文章提出了一种能够在网络层普适上层各种业务传输需求的新型QoS通用解决方案,它可以实现真正意义上的区分服务,为网络运营商的差别收费提供理论依据。With analyzing relation of the current QoS schemes and routing mechanisms, this paper points out the base of satisfying the need of different QoS operation is the differences of transport re- course. There is contradiction between the need of QoS and single-next-hop routing mechanism. Then we get the conclusion that the single-next-hop routing mechanism is the most important reason that affects the universal of QoS schemes. Based on the character of network layer＇ s multi-next-hops mechanisms, this paper proposes a new QoS scheme that achieves the purpose of general processing of the transport operation, and realizes distinguishing service in deed. Then ISP gain charge accord- ing to this scheme.
