Title: Method for VPN CoS Providing in BGP MPLS VPN Network
Inventor: KIM GWANG RYEOL
IPC: H04L12/50
Filed: 2002-05-20
Abstract: PURPOSE: A method for providing a VPN(Virtual Private Network) CoS(Class of Service) in a BGP(Border Gateway Protocol) MPLS(Multi Protocol Label Switching) VPN network is provided to offer a VPN service to support low-delay connection and low-loss connection without the necessity of an additional TE(Traffic Engineering) function by displaying the connection quality of a VPN site by using the top 2 bits of a VPN label allocated to identify the VPN site. CONSTITUTION: When a new VPN group is created and added to a PE(Provider Edge) router, an operator selects one among the connection qualities of the new VPN group(S10). Based on the selected connection quality, the PE router sets the top 2 bits of a VPN label allocated as a low-delay service display bit and a low-loss service display bit and creates a VPN label(S12). The PE router transmits routing information for the new VPN group and the created VPN label to the opposite PE router through an update message(S14). Receiving the update message(S16), the opposite PE router checks the top 2 bits and judges whether the low-delay service display bit is set as '1'(S18). In case that the low-delay service display bit is set as '1', the opposite PE router judges whether an MPLS LSP(Label Switched Path) to support a low-delay service exists(S20). If the low-delay MPLS LSP exists, the opposite PE router establishes the connection with the low-delay MPLS LSP so that VPN services can be provided to the new VPN group through the low-delay MPLS LSP(S22).
