Virtualization Mapping Algorithm For Heterogeneous Resources

Network virtualization technology has the very big significance for studying the development of the network. Network virtualization technology infrastructure providers and Internet service providers to separate, allows multiple operators can share the same public the underlying physical network infrastructure, each have their own share of the allocation of resources, virtual network different virtual network can use different network protocols, different network operators can provide a variety of innovative business applications. From another point of view,network virtualization technology provides an experimental platform, can be used to verify the actual physical network environment and the performance of the management system; It can make all kinds of heterogeneous network can run in parallel and independently, and their respective virtual network, test validate their performance. It also effectively solves the network architecture of the bottleneck problem.In this paper, the relevant virtualization technology and heterogeneous resources oriented virtualization mapping algorithm is studied, the main research work and results including, First of all, is a systematic study about the development of network virtualization technology and the network virtualization technology widely attention.And further study of the virtual network mapping technology, including the request by the virtual network to the underlying physical link mapping algorithm of node and link mapping algorithm. Firstly analyzes the existing limitations of the nodes in the network virtualization mapping algorithm, then proposed the HITS algorithm, HITS algorithm using authority and hub for the two values to reflect the topology. The authority of the node degree is affected by neighbors hub nodes, and the hub nodes are affected by the authority of the neighbor node, the two measures influence each other, the authority of a node and the hub degrees will be reflected on the whole topology. Through simulation implements the algorithm of node mapping, lays the foundation for reasonable allocation of resources as a whole. Mapping stage, the link and the link mapping stage, this chapter mainly introduces the shortest path algorithm, path integral algorithm. Path segmentation algorithm by path integral approach,mainly to a virtual distribution of bandwidth on the link to the different physical path, greatly enhance the utilization of resources in this way.Through the simulation, on the basis of the node mapping, map to find the right link. When link mapping, through node weight,mapping can be better to seek the appropriate link.
