A model of path fault recovery of MPLS VPN and simulation
Shumei Li, Hai-ying Liang · 2011
This paper puts forward a model of path fault recovery of MPLS VPN, which is DR-PFR(Double Recovery-Path Fault Recovery), for the failure on the path of MPLS VPN. DR-PFR can solve the failures in both the working path and the backup path. Experiments show that under the condition of using the resources effectively, when the network fails, DR-PFR can enable the network recover timely and effectively reduce the impacts on users.
