利用RSVP隧道高效实现INTERNET的服务质量请求

在ＩＮＴＥＲＮＥＴ上应用ＲＳＶＰ时，新增通信量和时空开销问题是ＲＳＶＰ研究的关键问题之一。文中提出了利用ＲＳＶＰ隧道和ＱｏＳ请求聚合体解决此问题的方案，核心内容是：ＱｏＳ请求聚合体代表多个具有指定特征的ＲＳＶＰ会话消息，隧道段的路由器的ＲＳＶＰ模块对聚合体会话消息设置软状态而不理会构成聚合体的单个会话消息、构成聚合体的每个一ＲＳＶＰ会话消息被封装后以普通数据包形式通过隧道段。

ACHIEVING QoS REQUEST EFFICIENTLY FOR THE INTERNET BY USING RSVP TUNNEL

Extra traffic as well as overhead of time and space produced by RSVP entities is one of the key problems in RSVP implementation in a Internet environment. A scheme is put forward to solve this problem through RSVP tunnel and QoS request aggregation in this paper. The essential idea of the scheme is as follows: an aggregation represents a number of messages of RSVP sessions with specific character, The RSVP module of router in a tunnel segment set soft states for the aggregation's message and do nothing for individual messages of RSVP sessions, each message of RSVP session are encapsulated and propagated through the tunnel. RSVP tunnel and QoS request aggregation are defined and their construction are studied. The procedure of forwarding messages of different classes are described. Comparison and evaluation show that QoS requests can be achieved in an efficient way by using this scheme.
