Abstract:
Internet has been developing for more than three decades ago. Considering its popularity, ubiquity and scale, it causes immense difficulty for other networks with different architectures to be deployed or even get adequately evaluated. This paper introduces a core/edge separation based architecture model, which allows core networks with various architectures to coexist, enables end users to choose whichever core network at will, and simplifies the design, deployment, operation and management of edge networks. In this model, Carrier Grade Ethernet, which is still on-going evolving, is selected as transport technology in the edge networks. A radically new approach called Bridging Virtualization is used to form a convergent access platform to these different core networks for end users. Besides the increasing flexibility for the edge transport carriers, this model also improves end users’ independence from the access provider. Moreover, it makes it possible the execution of network convergence step-by-step and can be used to realize it in the edge first. Finally, we apply this architecture model to design the campus networks of Tsinghua University, analyze its pros and cons and make some conclusion.
