在建立新连接时执行许可控制机制以确定是否应当许可该连接。准入取决于是否可以支持该新连接的QoS（服务质量）以及是否可以维持现有连接的QoS。已经设计了各种准入控制来提高网络利用率。然而，利用率优化是唯一的目标，具有不同的QoS要求的连接之间存在严重的不公平性，即，大带宽连接几乎没有被接纳。一个好的接纳控制不仅要达到高的利用率，而且要达到好的公平性。本文提出了四种新的基于测量的接纳控制，即数量保证，带宽段，半分区，和请求保持。仿真结果表明，我们提出的算法实现了更高的利用率和公平性比的测量和算法，目前已知的最公平的算法。
An admission control mechanism is performed while establishing a new connection to determine whether that connection should be admitted. Admittance depends on whether the QoS (quality of services) of this new connection can be supported and whether the QoS of the existing connections can be maintained. Various admission controls have been designed to improve network utilization. However, utilization optimization is the only goal, serious unfairness occurs among connections with different QoS requirements; that is, large-bandwidth connections are hardly admitted. A good admission control should achieve not only high utilization but also good fairness. This paper develops four novel measurement-based admission controls, namely, number guarantee, bandwidth segment, half partition, and request holding. Simulation results indicate that our proposed algorithms achieve a higher utilization and fairness than does the measure sum algorithm, presently the fairest known algorithm.
