摘要
分析当前新一轮科技革命和产业变革背景下城域网(Metropolitan Area Network,MAN)中不同用户的特征和对网络的需求,给出了通过引入边缘云将部分计算能力下沉到更靠近用户的地方,提供网络的灵活定制和确定性服务保障,满足不同场景和用户需求的建议。通过探讨当前城域网的现状,指出在现网引入边缘云时存在的主要问题,提出一种利用光交叉连接技术构建波长资源池来实现光电协同、灵活弹性连接的面向云网融合的全光城域网架构,最后介绍了基于此构架的边缘云业务承载方案。
This paper analyzes the characteristics of different users in Metropolitan Area Network(MAN)and their demands on the network under the background of the new round of scientific and technological revolution and industrial transformation,and gives some suggestions to sink some computing power closer to users by introducing edge cloud,so as to provide flexible customization and deterministic service guarantee of the network and meet the needs of different scenarios and users.By discussing the current situation of MAN,this paper points out the main problems existing in introducing edge cloud into the existing network,proposes an all-optical MAN architecture for cloud network convergence by using optical cross-connect technology to build wavelength resource pool to realize photoelectric cooperation and flexible connection,and finally introduces the service bearing scheme of edge cloud based on this architecture.
