Research And Application Of Campus Network Virtualization Technology For Cloud Computing

The campus network in vocational colleges has finished the coverage of the teaching area, office area, training experimentation area, life service area and so on; digital communication equipment, servers and other resources in campus network, providing a strong guarantee for the college teachers and students in teaching, management, training, research, learning, life and other aspects. But, with the expansion of college scale and the restriction of the traditional network technology, on the one hand, the college should continue to invest in expensive servers and other hardware devices; on the other hand, the information sharing degree is low in each department, and the information island is easy to form; and the low resource utilization at servers and other resources in different departments. Therefore, the campus network's management appear many problems,such as difficult, low efficiency and high cost.Virtual machine(VM),which is based on the virtual machine and the simulation and abstraction of the underlying hardware device, generates the independent function. Virtualized technology is the foundation and core technology of cloud computing infrastructure-as-a-service (IaaS), which solves the disadvantages of traditional campus network.In this paper, invested the current situation of vocational school network, analysised the existing problems of the campus network, the campus network virtualization technology in-depth researched, gave a upgrade from existing campus network virtualized technology to cloud computing infrastructure-as-a-service (IaaS). Selected H3C CAS products of cloud computing virtualization management platform, realized the construction of a higher vocational campus network computing virtualization, network virtualization, storage virtualization platform to build, deploy, manage and other projects. The main work of this paper is as follows:I presided over a vocational college construction projects of carrying out the " based cloud computing campus network virtualized platform (IaaS)". Researched on the key technology of campus network cloud computing and virtualization. Completed the work of vocational campus network virtualization platform planning, construction, virtual resource deployment and management operation. Through the cloud management platform, in the light of creating, modify, templating, clone, migration operation,completed the added 6 servers's campus network virtualization resource deployment, the server utilization rate increased to more than 70%, the cost decreased by 50%,the virtual machine's creation and management, computing resource's virtualization deployment, created the VSwitch, configured the switch IRF 2, and also completed the work for adding 2 new cloud core switches and 6 cloud access switches network resource, made the network management more simple, created the shared memory and shared file system, deployed the added 3 new capacity IP storage devices SAN 72TB's structurestorage resource virtualization, made the average disk utilization increased greatly. Realize the campus network virtualization resource management, cloud services and system testing work; In the light of the creatation, modification, template, cloning, migration and other operations, compled the VM management. Used EVB technology, completed VM traffic and edge management, For the organization and the administrator of the CAS, the creation of the user, complete the allocation of cloud service resources, etc. Developed cloud management platform virtualization resource monitoring and virtual machine testing work.In this paper, completed the virtual deployment and application of the campus network. Through the infrastructure virtualization platform cloud deployment, Effectively solved the problems such as low efficiency of server, information island and so on, improved the reliability and flexibility of the operation of the campus network equipment,made the campus network more intelligent and easy to use,had a very important significance to realize the education informationization in Higher Vocational Colleges.
