| Abstract(in English) | In this paper, We propose a methodology in MPLS(Multi Protocol Label. Switching) technology that will allow us to design pathways in real time, for the purpose of controlling the communication quality of IP-VPN(Dedicated Virtual IP Network) which is widely used for BtoB communications. The conventional MPLS technology specifies the accommodating network after designing the pathway in a centralized manner when configuring the communication pathway called LSP(label switched path). There has, however, been an element of concern on large scale carrier/commercial networks, as switching the communication pathway requires returning to Head End and recalculating it, if a problem occurs to a node in the configuration. The proposed methodology uses all LSP information that the node which propagates (transmit link information and the like to routers in the network) LSA in the MPLS network terminates, and distributes it to each node which will result in a real time pathway design. The DSCP (Diffserv Control Point) value shall be allotted to the Label value and Exp value so as to control the communication quality. This methodology, therefore, will enable us to specify the path depending on the network load and the usage status in a distributed manner on each node instead of returning to Head End and reconfiguring the pathway in the MPLS network. It will also enable us to control the communication quality by End to End to configure a detour path in a distributed manner. |
