Patent number: 10110555Abstract: A method applicable to a commonest application scenario, the method includes: an AR receives a first packet sent in a unicast manner by a CGN. The first packet includes information for indicating Restart announce, the first packet's source address is the CGN's address, and the first packet's destination address is the AR's address; AR changes the first packet's destination address to an address of a CPE connected to the AR, to obtain a second packet, where the AR and the CPE are connected by using a Layer 2 network, and the CPE's address is a multicast address; and the AR sends the second packet. The method is used for quickly informing, after the CGN restarts or undergoes an active/standby switchover, the CPE that an exception occurs, for example, the CGN restarts or undergoes an active/standby switchover, so that a CGN has relatively small load when recreating NAT mapping.Type: GrantFiled: November 29, 2016Date of Patent: October 23, 2018Assignee: Huawei Technologies Co., Ltd.Inventors: Min Zha, Jing Huang, Zhongjian Zhang

Patent number: 9577930Abstract: Embodiments of the present invention relate to a method for determining a multicast path, a method for receiving a data packet, and a router. The method for determining a multicast path includes: receiving, by a multicast address translation router, a first multicast join request packet, where the first multicast join request packet is an IPV4 packet, or the first multicast join request packet is an Internet Protocol version 6 IPV6 packet and a multicast address of the first multicast join request packet is an IPV6 multicast address obtained by performing Internet Protocol version translation on an IPV4 multicast address; and determining a shorter path between a first path and a second path. The multicast address translation router may determine the shorter path between the first path and the second path, thereby implementing a method for selecting a shorter path from the paths of different network types, which improves multicast efficiency.Type: GrantFiled: July 31, 2014Date of Patent: February 21, 2017Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventor: Zhongjian Zhang
