Abstract
According to an example of a method for forwarding a packet, a ESGW device decapsulates a received downstream data packet to obtain a downstream IP data packet when a destination MAC address of the downstream data packet is an MAC address of the ESGW device; determines a matching ARP entry of an IP address of a target user terminal based on the destination IP address of the downstream IP data packet to obtain a session ID of the target user terminal; determines a length field of a PPPoE header by a microcode, and obtains a pre-stored fixed-value field of the PPPoE header from a data storage area; encapsulates the downstream IP data packet into a downstream PPPoE data packet based on the session ID, the length field, and the fixed-value field, and forwards the downstream PPPoE data packet through an egress port of the matching ARP entry.
