Abstract: 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.

Abstract translation: 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。

Abstract: Example data transmission methods, devices, and systems are disclosure. One example data transmission method includes receiving, by an Ethernet device, an Ethernet packet, where the Ethernet packet carries a first packet header check bit used to perform a check on forwarding information of the Ethernet packet. A check on the forwarding information of the Ethernet packet is performed based on the first packet header check bit, and forwarding behavior of the Ethernet packet is determined based on a check result of the forwarding information of the Ethernet packet. A check is performed on the forwarding information, for example, a destination MAC address, of the Ethernet packet, and the forwarding behavior of the Ethernet packet is determined based on the check result.

Abstract: The present disclosure relates to operation, administration and maintenance (OAM) data transmission methods and apparatuses. One example method includes obtaining, by a first node, a first data flow of a client. The first node inserts an OAM data block in the first data flow of the client to obtain a second data flow of the client, where the OAM data block is a 64B/66B code block that carries OAM data. The first node distributes the second data flow of the client to at least one slot of a channel corresponding to the client.
