Design And Implementation Of Traffic Scheduling Scheme For DCI Networks

With the rapid development of Internet technology,more and more enterpris es have established their own data centers,and the data center is responsible for the organization of the core data in the enterprise.Normally the enterprise will establish many data centers,and through the data center network(Data Center Interconnect,DCI)of the multiple data centers are connected,so the data center network in the data center communication plays a very important role.Since twenty-first Century,the explosive growth of information between the enterprise data center transmission data volume gradually increased,then the data center network is facing many new problems: the complex network management is hard,low bandwidth utilization and difficult to implement automation control.Aiming at the problem of traditional data center network,this article analyzes the problem of traditional data center network,and the use of software defined network to design and implement flow scheduling scheme for data center network scenarios.The main contents of this paper include three aspects.First,b ecause of the characteristics of the data center network data transmission there is sudden and periodic,using strategic management to solve the difficult problem of temporary scheduling,and the strategy management includes strategy and link time strategi es.Second,selecting the way to achieve business by using the Dijkstra algorithm,Yen algorithm,to achieve the main contents include according to the routing constraints,according to the priority and seize the main path,and the path choice after the ne xt to the path for the maintenance and management.Third,multi label network management,The difference between MPLS(Multi-Protocol Label Switching,MPLS)network and traditional network is the traditional IP network based on IP packet forwarding,multi label network is forward by the label,so it can save time for parsing IP data message and lookuping route table,the label management in the network how to achieve label distribution and recovery of this paper will also discuss in this article.Also after the completion of the implementation scheme in the data center network,some test cases are also introduced in this paper,design a number of test cases,the analysis of the test results can know that the performance of the network has been improved,effectively reducing network congestion and improve bandwidth utilization rate.
