Building Method Based On Integrated Logic Bearer Network Load

After decades of development, internet has a profound impact on the people’slives and made a great contribution to social progress. But the increasing number ofnetwork users, large numbers of the new network business emerging, makingtraditional business-oriented network architecture is difficult to adapt to the needs ofthe development of the Internet, pointing that based on reconfigurable router, usingvirtualization technology, one of the development trend of future network is buildinga service-oriented integration bearer network.In this paper, firstly according to the limitations of the existing node mappingalgorithm, the paper propose minimum node load priority mapping algorithm. Thealgorithm uses the node memory load as the parameter of busying. By calculatingphysical load strength of node, selecting physical nodes that have a minimum loadand remaining resources to accept the mapping. Experimental results show that thealgorithm can get higher utilization of resources and the success building rate thanthe greedy node mapping algorithm when build logical carrying network. Then,taking into account the K short path link mapping is prone to bottleneck link, thepaper propose a link mapping algorithm which is based on link load balancing. Thealgorithm uses occupied bandwidth as the parameter of busying, calculating thedegree of link load balancing to determine link mapping, and based on the algorithmpropose a logic carrying network building method based on the load balancing. Theexperimental results show that the method can get not only higher resourceutilization and the success building rate, but also makes a more balanced networkload, avoiding the bottleneck resources appear. Making physical network can meetmore of the follow-up network construction requests. At last, the paper presents theimplementation of a logical bearer network, analysis the logic bearer network buildrequest, presents the basic model build request, the structure of domain mappingtable,building network request build process and preliminary design build logicalbearer network platform module.
