Abstract


Campus network size and network traffic is gradually expanding variety of applications are endless , single education network access has been unable to meet the bandwidth needs of the teachers and students to access network resources . In order to increase the export bandwidth and link redundancy , all colleges and universities to access other ISP (Internet Service Provider) to meet the increasing demand for bandwidth . Foreign visit after the multiple links belonging to multi- export gateway . Brings multi - ISP link access bandwidth to meet , but if there is no reasonable link options , park users still can not get high-quality service . The optimal choice of export gateway load balancing to achieve multi- ISP link the campus network is of great significance . Commercial export gateway load balancing products , but unable to meet the different needs of different application environment , and therefore need to design targeted export gateway load balancing scheme . But do load balancing scheme for link status , and server status link selection , this article is primarily designed a scheduling method based on the remaining capacity of the new link , and tested in the simulation environment of the campus network through the data collected to verify the feasibility of the new method . The main work of this paper are as follows: first , the analysis of the existing campus network multi - export gateway technology , introduced the background of this study , the research status at home and abroad , the main contents . Second, it introduces the concept of load balancing , clustering , load balancing defined several common load balancing algorithm . Linux network architecture and routing system . Third, the proposed new export scheduling method . Build a simulation campus network environment , and the new method is tested in a simulated environment , through the collection of data to verify the feasibility of the new method . Linux network architecture and routing cache proposed route cache optimization to improve the cache hit rate and can indirectly improve foreign access speed .
