A Research on the Distributed BGP Protocol for the Dual-Layer Distributed Controller

Abstract

Emergence and development of cloud computing, mobile Internet, and other relative technologies speed up the reform process of data center. The increasing demand on internet band width, diversity of Internet businesses, and Individualization of service delivery, etc. are imposing higher demands on the new-generation data center. Faced with the increasingly complicated Internet environment, traditional IP-based data center Internet structure has gradually exposed its limitations. In order to adapt to future Internet businesses, people engaged in this industry hold a mainstream opinion that “it’s time to give creative thinking over the basic structure of the Internet and adopt new design concept of the” and begin to pose high requirements on the features and functions of the future Internet system and structure. In recent years, emergence of software defined network (SDN) has provided a direction for development of future Internet. The idea of SDN originates in the Clean Stater4J Project, and with the in-depth development and research of technologies, the SDN structure has gone out of the laboratory and successfully stepped into the industrial circle. Having received wide recognition from both the academic and the industrial fields, the industrialization process of SDN and the standardization process of relative technologies have been pushed forward.
