The Research Of Sdn Resource Management Mechanism Based On Software Defined Price

Nowadays, information network is facing a variety of new challenges, software-defined network which has a strong ability to adapt to the dynamic is becoming the focus of attention.Software Defined Network is a new network architecture proposed by clean slate research group of the Stanford University.Its core is the separation of data planes and network device control plan.It can directly control the flexibility of network traffic through control equipments program.OpenDaylight is one of the most promising open source framework of SDN currently, OpenDaylight has been almostly achieved the establishment of an open, programmable and controllable reference frame through jointing open community developers, project management and open source code.The paper proposes SDN resource management mechanism based on Software Defined Price combining the concept of multi-homed architecture of bilateral market in economics and OpenDaylight architecture,and does a more in-depth discussion and research about the relevant technology in this mechanisms.Firstly,the paper introduces the research status and the future development trends of software defined network in detail, and makes a comparison between software defined network’s technology in the domestic and foreign. Secondly, proposes Multi-Agent price negotiation module based on the open source project OpenDaylight, and embeds the module into OpenDaylight architecture which made the main framework of OpenDaylight based on Multi-Agent. Thirdly,researching bilateral market in economic and applying multi-homed structure of bilateral market to SDN resource management mechanism by using interdisciplinary,and using multi-homed structure of bilateral market to build SDN resource management architecture through the main framework of OpenDaylight based on Multi-Agent,and proposes SDN resource management mechanisms based on the software-defined price and the corresponding resource selection procession. Fourthly, in this SDN resource management mechanism, the paper puts forward the concept of Software Defined Price(Software Defined Price,SDP).In SDP, the paper pricing the resource by combining mutil-Agent model,and proposes a dynamic resource price selection algorithm based on Game Theory.When allocating resource, the paper distributes resource using greedy allocation strategies and order allocation strategies on single or double platform.Finally, through simulation comparison on single platform and double platform under greedy allocation strategies or order allocation strategies, we can get a conclusion as follows:Whether on task completion cost or finish time, double platform has more advantages than single platform both under greedy allocation strategies and order allocation strategies, which illustrates the superiority of SDN resource management architecture based on Software Defined Price.
