Design And Implementation Of Virtualization Platform Control Framework Based On Software Defined Networking

Today,computer network technology not only combined with people's daily lives more and more closely,but also be an important means of support for many industries.However,the traditional tightly coupled architecture of network is becoming a bottleneck in development of network in recent years.The gradual rise of Software Defined Networking(SDN)technology innovation has brought new vitality for network innovation.However,before deploying any new technology and applications,it must be tested and verified.So,building a certain scale and real and can be controlled experimental platform has become an important way for a future network technology exploration and research.The purpose of this paper is to provide users with network innovative experimental platform.Firstly,study the current development situation of SDN Experiment Platform,understanding of combinetion with the situation virtualization and SDN technology,Furthermore,proposed the design of own test platform control framework,and complete the following tasks:Firstly,implemented the Web application platform.It provides a unified entrance,and provides resources visualization capabilities,experimental operations and deployment in the form of interactive pages.Secondly,designed and realized the resource scheduling module,support the custom settings topology,realization of the resources available control based on the resource visualization,allowing users to apply slice approach to resource partitioning,on-demand experiment the Internet.Design the foundation slice(Base-Slice)provide users with"plug and play" network services.Thirdly,designed and implemented network virtualization tools.Analysis and combined with existing virtualization platform technology,based on a customized network structure,through to the underlying link and port reuse,implemented support for multiple users,guaranteed traffic between users isolated from each other without disturbing each other,and to achieve a dynamic set of network bandwidth adjustment function,improve the utilization of network resources;Lastly,completed SDN virtualization platform control-framework in campus network deployment,and the function of the system performance test to verify the correctness of the system design.
