  • Abstract This paper proposes a new approach to support restoration of Label Switched Paths (LSP) set up in the MPLS network. The proposed scheme tries to establish all possible bypass tunnels according to the maximum bandwidth between two LSR around the protected Label Switched Router (LSR). The proposed scheme uses the idea of the maximum bandwidth between two LSRs and establishes the bypass tunnels passing through the critical links which will affect the maximum bandwidth between two LSRs. All of LSPs affected by a LSR failure or a link failure can choice a bypass tunnel fit its QoS constraints to reroute. This paper also compares the different between the proposed bypass tunnel and link disjoint bypass tunnel. The simulation result show that the proposed approach has better packet loss in rerouting and can allow more affected LSP to reroute compare to RSVP and efficient Pre-Qualify. The proposed bypass tunnels have better performance than link disjoint bypass tunnels.
