Application of BFD in the communication IP network
Ying Tang · Electronic Design Engineering · 2012
The communication IP network as the real-time data transmission carrier,requires the capacity of quickly detecting trouble in the link of communication between two systems,and quickly switching to the backup link,in order to guarantee the incessantly transmission of real-time date.Based on the study of BFD and according to the problems which occurred in application of the communication IP network,deploys BFD to realize switching between VRRP master and backup in milliseconds,and automatically changing to backup route from main route in static-routing protocol using single hop detection or multi hop detection,increasing the reliability of the network.
