摘要： This application discloses a method for obtaining a network slice. The method includes: receiving, by a control device, a slice request sent by a user, where the slice request includes an identifier, and the identifier is used to identify an isolation level of a slice requested by the user; obtaining, by the control device, an isolation type of the slice based on the identifier; and creating, by the control device, a network slice based on the isolation type of the slice and a resource topology, where the resource topology is used to describe a network topology and isolation capabilities of N elements in the network topology, the N elements include at least one of a node and a link, N is an integer greater than or equal to 1, and the network slice includes a node and a link that are required for implementing the slice.

摘要： 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.

摘要： 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.

摘要翻译：一种适用于最常应用场景的方法，所述方法包括：AR接收由CGN以单播方式发送的第一分组。第一个分组包括用于指示Restart announce的信息，第一个分组的源地址是CGN的地址，第一个分组的目的地址是AR的地址; AR将第一个分组的目的地址改变为连接到AR的CPE的地址，以获得第二个分组，其中AR和CPE通过二层网络连接，CPE的地址是组播地址; AR发送第二个报文。该方法用于在CGN重新启动或进行主备倒换之后快速通知发生异常的CPE，例如，CGN重新启动或进行主备倒换，使得CGN的负载相对较小重新创建NAT映射。
