摘要

软件定义网络（SDN）架构给网络带来了卓越的灵活性和可管理性。为了给新型SDN技术与应用提供大规模可行性验证试验床与试点部署平台，提出了依托于CERNET的层次化跨区域SDN 异地验证示范网络试验系统的总体架构，建设了9个城市、13个节点的SDN验证示范核心网与包含3个数据中心的接入网，并对基于SDN的vCPE智能专线业务、IPv4/IPv6过渡技术、流量监控调度应用和数据中心应用进行验证与示范。

Abstract

SDN architecture could bring excellent flexibility and manageability to the network.In order to provide a large-scale verification testbed and a pilot deployment environment for SDN-based new technologies and applications

a hierarchical and cross-regional SDN verification and demonstration system over CERNET was proposed

and a SDN verification and demonstration core network consisted of nine cities and thirteen nodes and an access network containing three data centers was built.Based on this system

several SDN-based technologies and applications such as CPE virtualization line service

IPv4/IPv6 transition technology

traffic monitoring and scheduling application and data center applications were deployed

verified and demonstrated.
