DYNAMIC PROBABILITY-BASED ADMISSION CONTROL SCHEME FOR DISTRIBUTED VIDEO ON DEMAND SYSTEM

机译:点播系统中基于动态概率的分布式视频访问控制方案

摘要

The dynamic probability admission control policy (10) for distributed video provides a method that decides in a Video on Demand (VOD) system which content requests can be admitted and which requests should be rejected to maintain Quality of Service (QoS). Requests for popular and expensive movies should not be rejected on the behalf of unpopular movies to generate more revenue. The dynamic probability admission control policy (10) combines a shared resource admission control (18) and a class-based admission control (14, 16). Moreover, dynamic probability is used to access shared resources, such as ports and bandwidth. A nonlinear dynamic probability function is used for allocation of ports/bandwidth. The dynamic probability admission control policy (10) improves performance of all the request classes, as well as overall system performance.
