Design And Implementation Of Virtual Network Mapping System Based On ONOS Framework In SDN Controller

With the rapid progress of network technology,it has led to the technological innovation at the bottom of the network,and gradually gave birth to a variety of new network technologies,such as network interaction based on the Internet of things,the Internet,and cloud platform data processing.There is also information data analysis and so on.However,with the in-depth use of users,the network infrastructure is not flexible enough.In order to solve this problem effectively,we introduced a method of using software to set up the underlying network —— SDN(Software Defined Network).In this paper,network virtualization mapping based on SDN is taken as the research goal.It mainly includes the following two aspects.(1)by analyzing the current research on network virtualization mapping algorithm,we can objectively find out its advantages and disadvantages,and find ways to improve the disadvantages.In this paper,nodes are used to make better use of network resources in some areas they manage,and an algorithm for virtual mapping operation in their regions is proposed.This scheme can significantly improve the success rate of mapping,and greatly improve the benefits of the network.(2)the research on network virtualization can not be separated from ONOS control.(2)the research on network virtualization can not be separated from the control of network.Performance analysis of the controller,the performance of the controller mainly depends on its overall architecture.The performance of ONOS is tested when it is developed,and then the architecture of virtual network mapping is designed and completed,and the architecture is also tested.There are two aspects of this architecture,one is an extensible forwarding architecture,which makes it possible to configure routing technology flexibly in ONOS,and to provide routing services to the outside world.Another aspect is the virtual network mapping architecture,which helps the virtual network to complete the mapping.What is implemented here is a technique with two-stage mapping,in which the forwarding rack is used in the link mapping phase The road finding service provided in the construction.At present,the discussion of ONOS is very popular,but the use of the controller in our country is still very limited.The discussion in this paper will be helpful to the theoretical basis of ONOS and the research of platform application.In this paper,the area aware network mapping technology is derived from the network virtualization mapping technology,which can increase the collection rate of virtual Internet mapping request and the long-term profit rate of the lower physical network.
