一类链路调度器的统一随机服务曲线研究

随着基于通信网络的业务应用不断的增加，已有的通信网络因所需负载的业务流种类的增加而需改进或提升服务性能。新设计出来的通信网络需为其所负载的业务数据流提供新的Qos服务保证．这要求寻找某种方法对计算机通信网络中的网络构成单元或其组合进行建模与性能保证分析。通信链路调度器网络构成单元对通信网络所能提供的Qos保证影响尤其突出．基于网络演算对这类通信网络构成单元及其组合进行服务保证分析，首先便是寻找这类网络构成单元的紧致性服务曲线。

Research on Unified Random Service Curve of a Link Scheduler

As the business applications based on communication network continue to increase, the existing communication network has to improve or enhance its service performance due to the increase of its loaded traffic flow types. Newly designed communication network has to provide new Qos service guarantee for its loaded traffic data flow, which requires us to find certain method to build a model for computer communication network construction units or their combinations, as well as to carry out the performance guarantee analysis. The particularly prominent influence upon Qos guarantee provided by communication network comes from the construction units of communication link scheduler network. When we analyze service guarantee of the communication network construction units and their combinations based on network calculus, the first thing is to find the compactness service curve of the network construction units.
