Comparative study on the user-controlled ISP switching for big data transmission in multi-isp-connected campus Network

Abstract

Most universities offer a low-speed commercial Internet for basic research and a separate high-speed R and E network for research requiring hundreds of tera-byte-class big data transmission. However, from a researcher's perspective, there is a limit to the use of high-speed network services provided by the R and E network because they basically have to choose one of them through a congested campus network. Therefore, for big data transmission, researchers should build separate optical networks inside the campus network for the connection of high-speed R and E network, or ask campus network managers to ensure bandwidth equal to most of the internal network bandwidth. Furthermore, campus network managers usually configure campus network to use commercial Internet. He/she manually provides R and E network connection as a request comes from user. This paper presents a new user-centered multi-ISP service method that enables users to efficiently overcome the current problems of IP routing, where dynamic changes to their ISP are not possible in nature. To overcome these problems, Fine-granule convergence of routing-related technologies is newly developed to provide user-oriented ISP switching.
