网络割接是对正在使用的线路、设备进行操作,将会直接影响到上面承载的业务,网络改造中最关键的一步就是网络割接。 网络割接又叫网络迁移,是指运行网络物理或者逻辑上的更改。网络改造中最关键的一步就是网络割接。
1:为了网络运行所以对线路进行割接,和服务器定时维护一样
2:性能提升,设备的更新
3:线路扩容或者说重新调整环网的树模式
4 :光路用光纤连接新老设备。
5 :数据电路割接用专用的数据电线来连接新老传输设备端子
通常,业务运行网络要求24小时不间断,而割接一般都是对正在使用的线路、设备进行操作,所以网络割接将会直接影响到上面承载的业务,这种割接一不小心就会造成业务应用的中断。如何制定最完善的割接方案、如何实行最完美的割接、如何规避割接中的风险、如何减少乃至消除对业务系统的影响,这些都是大家在割接前需要详细考虑的事情。
前期的准备工作一旦做得不好,割接中可能会遇到很多意想不到的问题导致割接失败,甚至无法回退到割接前的状态。
制定详细的割接方案
许多网络割接不是一步就能完成的,通常会分为很多次小的割接,这时候就需要一个总体的割接方案和许多具体的割接方案一起组合来描述整个过程。
割接方案不但是描述割接中需要进行的各项任务,还包含各项任务的时间表,所以相关的内容是需要各个配合部门、单位共同讨论通过的。
对于割接中的具体割接步骤,不能仅仅是空言无补,特别是牵涉到App版本的改变这种协议上有较大更改的情况,通常需要搭设模拟环境进行模拟割接测试。任何App都很难避免Bug(漏洞),网络起初的稳定运行不能说明在App版本改变、协议逻辑改动后依然能稳定运行。例如美国的一个大运营商就曾发生过路由器App版本大规模升级后几个小时后业务中断的情况。所以割接前的模拟测试是验证割接方案可行性的一个严谨的步骤,严格的测试有助于减少这方面的风险。
