    • PROBLEM TO BE SOLVED: To provide a packet transfer apparatus and method for transferring MPLS multicast packets over an Ethernet by using the MPLS (Multi Protocol Label Switching) label. SOLUTION: The packet transfer apparatus includes: a database 30 for storing address information for transferring MPLS multicast packets; a discrimination section 20 for discriminating whether or not a received packet is the MPLS multicast packet when receiving the packet from the other node, and discriminating whether or not the address of the packet is present in the database 30 when the received packet is the MPLS multicast packet; a packet processing section 40 for determining a node which is to be transmitted to the MPLS multicast packet whose address is present in the database 30 and for assigning an MPLS label in accordance with the address of the determined node; and a mapping section 50 for mapping the assigned MPLS label to an Ethernet target place MAC (Medium Access Control) address of the packet.

    • PROBLEM TO BE SOLVED: To provide an MPLS network and a mobile IP application method in the MPLS network, wherein an additional label-tunnel is set, in addition to an internal label between border routers, thereby carrying out packet transmission between a mobile node and a mating node. SOLUTION: In the mobile IP application method in the MPLS network, when the mobile node is moved from a location of a first border router to a location of a second border router, a label is allocated using the label-tunnel configured, by stacking a label doubly between the first border router and the second border router, and the second border router includes label mapping information, based on the allocated label in a register demand message and transmits it to the first border router, whereby a transmission/reception stage of a message related to the register and label allocation is reduced, the overhead generated in the network is reduced, and the load on managing a large amount of label forwarding table entry is decreased.

    • 要解决的问题:为了在MPLS网络中提供MPLS网络和移动IP应用方法,其中除了边界路由器之间的内部标签之外,还设置附加标签隧道,从而在 移动节点和配对节点。 解决方案:在MPLS网络中的移动IP应用方法中,当移动节点从第一个边界路由器的位置移动到第二个边界路由器的位置时,使用配置的标签隧道分配标签, 通过在第一边界路由器和第二边界路由器之间双重堆叠标签,并且第二边界路由器基于在寄存器请求消息中分配的标签来包括标签映射信息,并将其发送到第一边界路由器,由此发送/接收 降低了与注册和标签分配有关的消息阶段,减少了网络中产生的开销,减少了管理大量标签转发表项的负载。 版权所有(C)2007,JPO&INPIT
