Title: Fast rerouting method in mpls network
Inventor: JU YEONG DO
IPC: H04L45/50
Filed: 2000-11-22
Abstract: PURPOSE: A method for a fast rerouting in a multi-protocol label switching network is provided to make a rerouting of a traffic possible at a high speed by minimizing a packet loss for a protection and a recovery of a multi-point to point LSP(Label Switched Path) in an MPLS(Multi-Protocol Label Switching) transmission network. CONSTITUTION: A back up LSP must be pre-established for embodying a high speed rerouting function of a multi-point to point LSP, that is, for minimizing a packet loss when a trouble is generated. The back up LSP comprises two path segments. The first path segment consists of a point to multi-point reverse anycast tree for making an egress LSR of a multi-point to point LSP to be protected into a root and going back a composition link of the multi-point to point LSP to the reverse direction and reaching to an ingress LSR. The second path segment is an ER(Explicitly Routes)-LSP created from an ingress LSR to an egress LSR and not including a composition link of a multi-point to point LSP to be protected. In a packet transmission to an anycast tree, one packet transmitted by a root is transmitted to only one place of many leaf nodes although a packet is transmitted to only one path. In case that a trouble is generated a link between an LSR6 and an LSR8, the LSR6 performs a loopback of a traffic stream in the reverse direction for flowing toward a reverse anycast tree.
