摘要
文中提出了一种新的以时间作为目的地序号来解决路由环路的方法。其主要思想是对消息项序号的重新设计,添加时间(Time Of Day,TOD)信息,避免因为节点休眠重启或者路由超时删除时,路由消息项序号重新计数引发的重复广播过期路由消息项的问题。按照路由更新的原则,选择消息项序号最新的消息项,从根本上解决了路由消息循环传输的问题,确保在任何时刻网络中都不会存在路由消息循环和暂态路由环路。
This paper describes a new method for solving the looping problem with time-of-day as the destination sequenced number. The main concept is to re-design the sequenced number of message and add time-of-day information to this sequenced number,thus to avoid transmitting the overdue routing information in virtue of restarting after dormancy or deleting the overtime routing information,which would result in the problem of recounting the sequenced number of message. Thus the looping transmission in routing message distribution is solved completely,and no existence of routing-message looping and transient routing loops at any time in the network is guaranteed.
