US 2026/0074925 A1 · PACKET FORWARDING METHOD AND APPARATUS, AND SYSTEM

Abstract

A packet forwarding method and apparatus. A first network node located at a boundary between a first network domain and a second network domain receives a first packet from the first network domain, where the first packet includes a first packet header that matches the first network domain, and the first packet header includes a first slice identifier that indicates a first network slice. The first network node obtains a second packet based on the second network domain and the first packet, where the second packet includes a second packet header that matches the second network domain, the second packet header includes a second slice identifier that indicates a second network slice, and the second packet header is different from the first packet header. The first network node sends the second packet in the second network domain based on the second slice identifier.

Dependent claims

A packet forwarding method, applied to a first network node located at a boundary between a first network domain and a second network domain, wherein the method comprises:

receiving, by the first network node, a first packet from the first network domain, wherein the first packet comprises a first packet header that matches the first network domain, and the first packet header comprises a first slice identifier that indicates a first network slice;
obtaining, by the first network node, a second packet based on the second network domain and the first packet, wherein the second packet comprises a second packet header that matches the second network domain, the second packet header comprises a second slice identifier that indicates a second network slice, and the second packet header is different from the first packet header;
and
sending, by the first network node, the second packet in the second network domain based on the second slice identifier.

1 more element

A packet forwarding apparatus, used in a first network node located at a boundary between a first network domain and a second network domain, wherein the apparatus comprises:

a memory storing instructions;
and
a processor coupled to the memory to execute the instructions to:
receive a first packet from the first network domain, wherein the first packet comprises a first packet header that matches the first network domain, and the first packet header comprises a first slice identifier that indicates a first network slice;
obtain a second packet based on the second network domain and the first packet, wherein the second packet comprises a second packet header that matches the second network domain, the second packet header comprises a second slice identifier that indicates a second network slice, and the second packet header is different from the first packet header;
and
send the second packet in the second network domain based on the second slice identifier.
