摘要： A data transmission method is provided. The method is used to transmit multiple data packets, and includes the following steps. Multiple acquired data packets are mapped to different sessions according to data header information of the data packets, in which each session corresponds to one or more data packets. A data packet is encapsulated into a session message, in which the encapsulated session message includes a session identifier of the session corresponding to the one or more data packets. Multiple session messages belonging to the same session are transmitted to a next network node through at least two tunnels in link layer.

摘要： A binding/unbinding processing method, system and apparatus are disclosed. The binding processing system includes: an Internet Protocol (IP) edge node and an Access Node (AN). The IP edge node is configured to: monitor received Dynamic Host Configuration Protocol (DHCP) messages, after monitoring a specific DHCP message, forward the specific DHCP message to all ANs corresponding to bound links, where the specific DHCP message is a DHCP ACK or DHCP REPLY message. The AN is configured to: receive the specific DHCP message sent by the IP edge node, parse and obtain an IP or Media Access Control (MAC) address carried in the specific DHCP message, and bind a port of the AN to the IP or MAC address according to the obtained IP address or MAC address. The present disclosure implements the binding/unbinding of an AN port to/from an IP or MAC address in inter-AN binding scenarios.
