基于双边市场多归属结构的SDN资源管理机制

现有IP网络在近几十年创新不足,软件定义网络(SDN)也许是下一轮的网络技术革命,并将带来巨大的市场潜力。从SDN架构出发,通过分析OpenDaylight项目和双边市场理论,提出了基于双边市场多归属结构的SDN资源管理体系结构和一种扩展的FPM多平台选择算法。在仿真测试中,主要通过单双平台在不同资源分配策略下的任务完成时间和代价来说明该体系的优势,由此实现了SDN中资源的合理分配,并提高了网络的可靠性。     

ForCES网络中的资源调度算法和经济模型(英文)

Resource scheduling algorithm for ForCES(Forwarding and Control Element Separation) networks need to meet the flexibility,programmability and scalability of node resources.DBC(Deadline Budget Constrain) algorithm relies on users select cost or time priority,then scheduling to meet the requirements of users.However,this priority strategy of users is relatively simple,and cannot adapt to dynamic change of resources,it is inevitable to reduce the QoS.In order to improve QoS,we refer to the economic model and resource scheduling model of cloud computing,use SAL(Service Level Agreement) as pricing strategy,on the basis of DBC algorithm,propose an DABP(Deadline And Budget Priority based on DBC) algorithm for ForCES networks,DABP combines both budget and time priority to scheduling.In simulation and test,we compare the task finish time and cost of DABP algorithm with DP(Deadline Priority) algorithm and BP(Budget Priority) algorithm,the analysis results show that DABP algorithm make the task complete with less cost within deadline,benifical to load balancing of ForCES networks.
