Packet forwarding method, apparatus, and system, and computer-readable storage medium

A packet forwarding method, wherein the method comprises:

• generating, by a service node, a first message, wherein the first message comprises a computing power resource level of an application service deployed in the service node;
• and
• sending, by the service node, the first message to a first device,
• wherein
• each of the first messages further comprises an application service identifier of the application service deployed in the corresponding service node and an Internet Protocol (IP) address of an instance of the application service deployed in the corresponding service node, or
• each of the first messages further comprises an anycast IP address corresponding to the application service deployed in the corresponding service node.

A packet forwarding apparatus, applied to a first device, wherein the apparatus comprises:

• at least one processor;
• and
• one or more memories coupled to the at least one processor and configured to store instructions for execution by the at least one processor, the instructions, when executed by the at least one processor, cause the apparatus to:
• receive a packet sent by a second device, wherein the packet comprises indication information and an application service identifier;
• determine a target service node based on the indication information and the application service identifier, wherein a service capability of the target service node matches the indication information, and a target application service corresponding to the application service identifier is deployed in the target service node;
• and
• send the packet to the target service node,
• wherein the instructions, when executed by the at least one processor, further cause the apparatus to:
• receive a first message sent by any service node in the plurality of service nodes, wherein the first message comprises a computing power resource level of an application service deployed in the any service node.
