RSVP协议上的ELSD代价分配方案

本文讨论ＲＳＶＰ协议（资源保留协议）在多点播送分布树环境下的ＥＬＳＤ代价分配方案，问题是，当一个数据流在多个接收者之间共享时，如何在使用者之间分割充的网络代价，根据ＲＳＶＰ协议所能建立的三种不同的资源保留类型，本文分别给出了简单ＥＬＳＤ和加权ＥＬＳＤ两种不同的代价分配方案，以求得在接收者之间公正，合理地分配代价，达到制约使用者合理使用资源的目的。

ELSD COST ALLOCATION ON RSVP

This paper discusses cost allocation in the context of distributed multicast tree on the protocol of RSVP(resource ReSerVation Protocol). The question we discuess is:when data flows are shared among many receivers,how to split the network cost of data flows among the users. According the resource reservation styles that the RSVP can establish,this paper proposes two scenarios of cost allocation: the simple ELSD and the weighted ELSD, in order to allocate the cost among the receivers fairly and reasonably,so that the network resource can be used among the users rationally and efficiently.
