基于SDN框架的网络资源定价策略

针对网络中用户集中提出资源请求所造成资源负载过重和网络拥塞的问题，提出一种基于SDN架构的网络资源定价策略。首先，分析用户的需求和消费模式，确定资源交易模型。其次，结合现货消费模式和计划消费确定预约机制下资源动态定价策略模型。最后，根据所提出的资源定价策略，对资源价格进行实例仿真，结果表明，通过价格刺激用户提前预约资源，结合每个用户的信任度与消费习惯给出相应的优惠价格，可以有效地避免用户集中获取网络资源。

Network resource pricing strategy based on SDN framework

A network resource pricing strategy based on SDN framework was proposed to solve the problem of resource overload and network congestion caused by resource requests in the network.Firstly,the user’s needs and consumption patterns were analyzed,and the resource transaction model was determined.Secondly,combined with the spot consumption model and plan consumption,the reservation mechanism under the resource dynamic pricing strategy model was determined.Finally,according to the proposed resource pricing strategy,the resource price was simulated,the results show that by stimulating the user to reserve resources in advance and combining the trust degree and consumption habits of each user with corresponding preferential prices,it is possible to effectively avoid the users from obtaining network resources in a centralized manner.
