An identification based network link backup method

Abstract


in order to solve the problem of network link failure or link congestion, this paper proposes an identifi cation based link
backup method, which uses the identification network to carry out collaborative backup of links, formulates the link level through the
network identifi cation mechanism, divides the routing characteristics through the link level, and calculates the link level through the link
backup protocol between routers. When the high priority link fails or the link congestion occurs, the low priority link can be used for
routing; When the transmission rate of a single link decreases, the low priority link can also be enabled. So as to achieve network load
balancing and maximize link utilization. Through mini net simulation, the experimental topology is built and verifi ed. The results show that
this method can quickly repair the link failure, quickly switch the link, reduce the network interruption delay, when the high priority link
failure or congestion, it can quickly establish the route update, and quickly recover, so as to achieve the purpose of network load balancing.
