Abstract: A method for sharing a backup path in a MultiProtocol Label Switching (MPLS) network, a label switching router (LSR) for setting a backup path in an MPLS network, a system for setting a backup path in an MPLS network, and a recording medium therefor are provided. The method includes the steps of acquiring link configuration information of links included in a working path when the working path is set between a source node and a destination node, and allocating bands for a backup path using the link configuration information when the backup path is set between the source node and the destination node. In the method, an optimal band is allocated to each of links included in a backup path by calculating a band using information, which is obtained during setting of a working path, about at least one other working path sharing links with the working path when the backup path is set, thereby efficiently managing network resources without wasting them.

Abstract: PURPOSE: A multicast service method in an MPLS(Multi Protocol Label Switching) network is provided to eliminate the consumption of resources due to path establishment by making all groups share a previously established LSP(Label Switched Path), instead of forming a distribution tree for each group. CONSTITUTION: A BSR(BootStrap Router), the highest priority node among RP(Rendezvous Point) nodes, broadcasts an integrated, certified bootstrap message to the RP nodes periodically, and the RP nodes broadcast bootstrap messages to their respective LERs(Label Edge Routers)(101). Subscriber terminals transfer join messages to RP nodes through LERs respectively. The LERs and the RP nodes get to a group data forwarding state and a multicast forwarding state respectively by the transmitted join messages(102). If a packet is received from an arbitrary subscriber terminal to an adjacent LER(103), the LER analyzes the header of the received IP packet(104). Based on RP information delivered from the bootstrap message, the LER transfers the packet to an RP node appointed to service a group specified as the destination of the packet(105). The RP node reproduces the transferred multicast data packet as much as the number of LERs to which the members of the group are connected and delivers them to the LERs through an LSP(106). Each LER reproduces the delivered packet as much as the number of group members in an external network and delivers them to the subscriber terminals(107).

Abstract translation: 目的：提供MPLS（Multi Protocol Label Switching，多协议标签交换）网络中的组播服务方式，通过使所有组共享先前建立的LSP（Label Switched Path，标签交换路径）来消除路由建立造成的资源消耗，而不是形成分布树 每组。 规定：RP（Rendezvous Point）节点中最高优先级节点的BSR（BootStrap Router）周期性地向RP节点广播一个综合认证的引导消息，RP节点将自举消息广播到其各自的LER（Label Edge Routers） （101）。 用户终端分别通过LER将消息传递到RP节点。 LER和RP节点分别通过发送的加入消息（102）获得组数据转发状态和组播转发状态。 如果从任意用户终端接收到分组到相邻的LER（103），则LER分析所接收的IP分组（104）的报头。 基于从引导消息传递的RP信息，LER将分组传送到被指定为服务于指定为分组的目的地的组（105）的RP节点。 RP节点再现传输的组播数据分组，与组中成员所连接的LER的数量一样多，并通过LSP将其传递给LER（106）。 每个LER将传送的分组与外部网络中的组成员的数量一样再现，并将它们传送到用户终端（107）。

CONSTITUTION: A subscriber interface setup unit(46) sets a subscriber interface on a front of an ingress forwarding engine(41) or on a back of an egress forwarding engine(44). An LSP setup unit(47) for a high reliable MPLS-VPN sets an internal channel for LSPs in a switch(45). The subscriber interface setup unit(46) comprises as follows. An MPLS-VPN service packet determiner determines packets for receiving an MPLS-VPN service.

Abstract: PURPOSE: A method for sharing a backup path in an MPLS(Multi Protocol Label Switching) network is provided to assign an optimal band amount by using information on other shared working paths when calculating a necessary band during backup path setting, thereby efficiently managing network resources. CONSTITUTION: A path calculator of a starting LSR(Label Switching Router) calculates a working path LSP1(Label Switched Path1)(S701). The path calculator transmits a path setup request message to a signaling unit to request a path setup(S702). The signaling unit designates each LSR as explicit routes, and transmits a label assignment request message to an intermediate LSR(S703). Each LSR attaches an ID of a working LSP to the label assignment request message, and transmits the message to a next intermediate LSR(S704). A destination LSR creates a label mapping message including working LSP information inserted by each LSR, and retransmits the created message to the intermediate LSR(S705). The intermediate LSRs transmit the label mapping message in opposite direction, and transmit the message to the starting LSR(S706).
