In tranditional ip network, only the “ best effort ” service is provided, but the quality of service can not be guaranteed. though the interserv, deffserv and mpls are presented afterward to guarantee the qos for the ip network. but as a layer network, the realization of the qos function need span different layers ( such as rsvp protocol ) in the ip network, which may result in the function iterance and chaos
多媒體和實時業務的出現要求網路能夠提供足夠的qos保證，在傳統的ip網路中只能提供「盡量傳輸」的服務而不能保證服務質量，后來提出的綜合服務模型（ interserv ）以及區分服務模型（ deffserv ）以及mpls技術保證了ip網路上的服務質量，但由於ip網路是層次結構的網路，因此對qos的支持需要跨層（如rsvp協議） ，這就可能引起功能的重復和混亂，而微通信元系統是無層次結構的網路系統，就克服了這些的問題，變得簡單，效率更高。 -
In chapter 3, two novel scheduling algorithms are put forward to supporting qos according to bin packing problem. bhps arriving are sent to different queues according to their outport, in each ourport queue, bhps are classified by their priorities and scheduled as a batch. the simulation results shows that ffd and bfd not only can provide qos effectively, but also can improve the average loss function
