Downstream packet sending and forwarding method and apparatus

A downstream packet forwarding method, comprising:

• receiving a downstream packet sent by a core switch, wherein the downstream packet comprises a source medium access control (MAC) address, wherein the source MAC address indicates a downstream forwarding path of the downstream packet, and the source MAC address further indicates a priority of a terminal device;
• determining, based on the source MAC address, an egress port corresponding to the downstream packet;
• and
• sending the downstream packet through the egress port, wherein the sending the downstream packet through the egress port comprises:
• placing the downstream packet into a forwarding queue corresponding to the priority;
• and
• sending the downstream packet through the egress port according to the forwarding queue.

A downstream packet sending apparatus, comprising:

• a non-transitory memory storage comprising instructions;
• and
• one or more hardware processors in communication with the non-transitory memory storage, wherein the one or more hardware processors execute the instructions to:
• configure a downstream forwarding path of a downstream packet for a terminal device;
• generate a source medium access control (MAC) address based on the downstream forwarding path, wherein the source MAC address indicates the downstream forwarding path, wherein a most significant byte in the source MAC address represents a type of the source MAC address, a second most significant byte represents a priority of the terminal device;
• and
• send the downstream packet to a forwarding switch, wherein the downstream packet comprises the source MAC address.
