Multi-link Access Campus Network Optimization Strategies For External Services

Campus network is regarded as the application of the network technology in education, change the traditional idea of the teaching of school education in varying degrees, and pass educational information construction, promoting every work of the school to reach a new high. The networking of campus has already become the basic construction project of the school progressively,become and weigh the education information of a school and modernized important sign.Do campus network construction well,construct modernized education enviroment,is the important contenr of the education modernization, it is aslo the important component of forming the modernized school system.Now, University adopt many pieces of chain insert school this under the background of network generally,campus network foreign service quality reached a kind of ideal state,each chain is uneven in load, different user visit school service pace difference relatively loud, The common network address leans towards development waiting for the reason to restrict campus network little in the school.So, On the basis of combining the real work and doing a large number of investigations, through adopting relevant technology and method,for example, NAT switch technology, technology of load balancing, consult relevant ripe system models.For instance distinguish the model of serving,CDNmodel,thus reach and optimize the foreign service quality of campus network., Purpose to promote teaching, scientific research and management level.This subject has recommended many chains to inser under the enviroment of campus network, current situation analysis of the foreign service quality of campus network, and put forward the corresponding solution on chain tactics link. On the overall design phase of system optimization, consult XXYJY model,set up the thought of optimizing, optimize the step clearly. In system optimization fully consider design original intention and characteristic of campus network of many chains,set the starting point studied free on the strategy at exit especially,use the technology of the dynamic domain name,technology of load balancing, CDN consults models,compare with every chain load situation and different extranet user visit the service situation in the school optimize.This system has several creative achievements and theories。At first, apply CDN model to campus network, increase the network framework with new one storey between service of existing campus network and student's user, release the contents of websites to edge of network most close to users, use the family to make the necessary content differ nearby, solve the congested state of Internet network, improve the response speed that users visit websites. Secondly, dispose DNS service under different environments, make campus network ask, realize to outside visit of user intelligence distinguish and accomplish key business redundant and spare. Lastly, Overall application of the technology of load balancing in campus network, consult the riper load balancing algorithm, realize the load balancing of chain.
