摘要:

SDN(软件定义网络)和NFV(网络功能虚拟化)技术已成为当前的研究热点。vCPE(虚拟用户驻地设备)的主要思路是将原来的CPE一分为二,保留原有用户侧CPE的二层功能,而将三层功能以及业务处理功能上移至云平台中。采用此方法,不仅可以简化原有CPE实体网关设备,降低用户操作维护的难度,同时也可降低上门服务概率,并为用户提供增值服务。研究了vCPE中用户侧CPE如何与网络侧云平台建立连接的问题。通过采用VxLAN和NvGRE技术,在实现用户侧CPE与云平台建立二层通信的同时,对现有海量CPE的改动较小。

Abstract:

SDN and NFV technology have aroused more and more attention. The main idea of vCPE is to split the CPE into two parts and to make the L3 functions up to the network. Through this method, CPE can be simplified and the difficulty for subscribers to operate and maintain CPE can be reduced. For operators, vCPE can reduce the probability of on-site service, and can provide value-added services for subscribers. The problem of connection between the CPE and the cloud platform was studied. By using VxLAN and NvGRE, the L2 connection between CPE and cloud platform could be established, and at the same time, the change to existing huge CPEs was small.
