中心局网络重构

Central Office Re-Architectured Network as Datacenter

中心局是运营商最重要的业务资产,是离用户最近的网络设备的"家",装载了大量的新老接入设备。传统的电信机房是一种"黑盒子"解决方案,运营商被迫捆绑于某一设备供应商,造成设备种类繁多、运维成本居高不下、更新升级困难的窘境。网络就是信息高速公路,传统的网络只是信息的传输者,今天的网络除了作为信息的传输者,更重要的还是信息的存储库和信息的源泉,由此带来了网络架构的变革,这种变革从引入数据中心开始。传统的网络因业务而生并随之固化,缺少弹性和开放性;未来的网络则是包容万物的,计算无处不在,软件定义一切,连接随手可及,宽带永无止境,数据融入智慧。于是,必然要引入第三个关键词:重构。本文侧重于中心局网络的重构,业界称之为CORD,重点解读三个应用场景:R(Residential)-CORD面向家庭住宅场景、M(mobile)-CORD面向4G/5G移动网络、E(Enterprise)-CORD面向政企用户场景。可以畅想,某一天我们重返中心机房,一切都是陌生的,原来的设备都被肢解了,机房变成了云化的数据中心。这就是电信业正在发生的一次剧变,这种剧变才刚刚开始。

Firstly,the central office is regarded as the most important asset of operators,and is the closest buildings to the users.It accommodates a lot of network equipment,from quite earlier old to the newest ones.Traditionally,it takes a " black box" solution,and operators are so forced to bind their solutions to the venders,which causes a large variety of equipment types,high operation and maintenance costs,and hard to upgrade.Secondly,the network is really the information superhighway,and traditionally,it provides transformation of information across the world.Today,however,except for information transportation,what is most important,it also acts as repository and source of information with the emergence of data center inside the network.The traditional network is established and so fixed to some given services,and is so lack of flexibility and openness.The future network will be an all-round player,which will integrate with ubiquitous computing,software defined hardware,being readily accessible,with continuous increasing bandwidth,everything connected,and even intelligence everywhere.Therefore,it needs to introduce the third key words:re-architecture.Herewith this presentation will focuses on the Central Office Re-architectured network as Datacenter,which is called as CORD as an open project.Typically,it has three application scenarios:R(Residential)-CORD with fiber access,M(mobile)-CORD for 4 G/5 G,and E(Enterprise)-CORD for industry.Let’s imagine that,one day in the near future,when we return to the central office,everything is changed.All the traditional equipment have been disaggregated,and all are re-architectured as data center.This is the undergoing telecommunications transformation and will be evolved for a quite long period.
