接纳控制解决的问题是一个网络资源连接请求是否可在不影响其它连接的基础上被接纳，同时协调不同的连接请求之间如何进行响应、如何分配带宽、如何控制时延。而网络演算是网络系统进行性能分析的工具，主要通过到达曲线和服务曲线来实现，本文对基于网络演算的接纳控制算法进行研究，主要从有保证的网络服务质量和较高的网络资源利用效率角度进行，首先对网络演算的定义和实现工具作了简介，然后概括了现有的接纳控制模型并对其性能优劣进行了分析，最后对基于网络演算的接纳控制算法进行了实现。%Whether a network resource connection request can be accepted without affectingother connections is an issue theadmission control deals with.It also tackles response coordination among differentconnection requests, bandwidth allocation, and delay control. Network Calculus is a network system performance analysis tool, achieved through arrival curveandservice curve.This paper studies admission control algorithm based on network calculus, with guaranteed network service quality and high network resource efficiency being its focus. It firstly introduces the definition and the implement tools for network calculus, goes on withtheexisting admission controlmodels and theirperformance advantages and disadvantages, and concludes with the realization of admissioncontrolalgorithm based onnetwork calculus.
