基于多播前缀和流行度感知的区间缓存接纳控制策略
Multicast Transmission Prefix and Popularity Aware Interval Caching Based Admission Control Policy
摘要：
接纳控制是多媒体服务器中的一个关键组成部分，它将允许客户端仅在资源可用时才使用资源。众多内容服务机器面临的问题是过载，当有太多客户端需要服务时，服务器往往会变慢。用于多媒体服务器的准入控制算法负责确定是否可以在不违反系统中现有请求的QoS要求的情况下接受新请求。通过在同一对象上的两个连续请求之间的间隔中仅缓存和流式传输数据，可以直接从缓冲区缓存中为以下请求提供服务，而无需磁盘操作并且在请求的截止日期内。一种基于流行度感知的Prefix区间缓存的接纳控制策略[3]通过考虑多媒体对象的不同流行度来扩展区间缓存。流行对象的多播传输的前缀缓存方法有效地利用了硬盘和网络带宽，并增加了被服务的请求的数量。
英文摘要：
Admission control is a key component in multimedia servers, which will allow the resources to be used by the client only when they are available. A problem faced by numerous content serving machines is overload, when there are too many clients who need to be served, the server tends to slow down. An admission control algorithm for a multimedia server is responsible for determining if a new request can be accepted without violating the QoS requirements of the existing requests in the system. By caching and streaming only the data in the interval between two successive requests on the same object, the following request can be serviced directly from the buffer cache without disk operations and within the deadline of the request. An admission control strategy based on Popularity-aware interval caching for Prefix [3] scheme extends the interval caching by considering different popularity of multimedia objects. The method of Prefix caching with multicast transmission of popular objects utilizes the hard disk and network bandwidth efficiently and increases the number of requests being served.
