基于优先级的云平台视频配置网络算法

Cloud Platform Video Network Configuration Algorithm Based on Priority

为解决云视频配置网络不能满足用户需求、不能保证服务质量以及用户使用成本高等问题,设计基于优先级的视频配置算法。利用视频受欢迎程度算法和分布式控制法解决视频网络中面临的资源消耗问题和副本配置问题。根据会员用户和非会员用户区分用户请求的优先级,会员用户比普通用户享有更高的资源优先使用权,即可以优先使用。利用网络上常见的团购策略帮助需要高视频质量但资金有限的用户解决消费成本问题,参与团购的用户越多,享受的优惠越高。

In order to solve the problem that the cloud video configuration network could not meet the needs of users,guarantee the quality of service and cost lowly,video configuration algorithm based on Priority was designed.The video popularity algorithm and distribut control method was used to solve the problem of resource consumption and replica configuration in the video network.The priority of user requests is distinguished according to member users and non member users.Member users had higher priority to use resources than ordinary users.The common group buying strategies on the network was used to help users who needed high video quality but had limited funds to solve the problem of consumption cost.The more users participate in group buying,the higher the discount they could enjoy.
