Abstract
Admission control s oftware i s used t o make accept or deny decisions about incoming s ervice requests to avoid overload. Existing media streaming s oftware
includes only limited support f or admission control by allowing for predefined static rules. Such rules limit for example t he number of requests that are allowed to enter the s ystem during a certain time or define thresh-olds concerning the utilization l evel of a single resource such as network bandwidth. In media s treaming appli-cations, however, the bottleneck resource (CPU, Disk I/O, network bandwidth, etc.) might change over time depending on the current demand for different types of audio or video files. This paper proposes a m odel for adaptive admission control i n t he presence of multiple scarce resources. Opportunity costs for a service r equest are determined at the m oment of an incoming r equest and compared to the r evenue of a r equest i n order to make an accept/deny decision. Opportunity costs are based on resource utilization, service r esource require-ments, expected future demand for s ervices, and the r ev-enue per accepted service. The m odel allows rejection of service r equests early to reserve capacity required to perform future service r equests with higher revenues. We describe a number of experiments t o illustrate the benefits of adaptive admission control m odels over static admission control rules.
摘要 接纳控制软件是用来接受或拒绝决定输入的服务请求软件，从而避免过重的负担。现有的流媒体只支持有限的软件，其中就包括接纳控制软件。接纳控制软件使用他们预先定义的静态的规则。这种规则限制例如静态数据要求在一定时间内都不准进入系统，或定义有关阈值利用水平的一个单一的资源，如：网络带宽。然而，流媒体应用的瓶颈资源(CPU，磁盘I / O，网络带宽等) 依靠目前的需求可能会随时间改变为不同类型的音频或视频文件。本文提出了一种新的模型自适应接纳控制，在他面前的数倍稀缺的资源按机会成本来确定服务请求是当前请求，对照收入请求形成一个接受/拒绝的决定。机会成本是基于资源利用、服务资源需求预计未来需求与收入接受的服务。该模型允许拒绝服务请求过早的备用容量来完成未来服务请求与更高的收入。我们描述了一系列实验现象，说明了在静态的接纳控制模型的自适应的接纳控制规则的好处。
