Traffic scheduling method, apparatus, device, storage medium, and program product

A computer device, comprising:

• a memory and a processor, wherein the memory and the processor communicate with each other, the memory has computer instructions stored therein, and the processor executes the computer instructions to thereby execute a traffic scheduling method comprising:
• in response to a domain name resolution request of a business application, forwarding the domain name resolution request to a central domain name system, wherein the domain name resolution request carries a target domain name of the business application, the central domain name system is configured to forward the domain name resolution request to a target egress gateway corresponding to the target domain name, and the central domain name system is preconfigured with gateway information of egress gateways corresponding to a plurality of domain names;
• receiving a first target network address and a gateway address of the target egress gateway that are fed back by the central domain name system, wherein the first target network address is obtained by the target egress gateway by sending the domain name resolution request to a corresponding first domain name resolution server for domain name resolution;
• performing network address translation on the first target network address to obtain a virtual network address;
• and
• performing data transmission based on the virtual network address, the gateway address, and the first target network address.

A non-transitory computer-readable storage medium, wherein the computer-readable storage medium has computer instructions stored thereon, and the computer instructions are used to cause a computer to execute a traffic scheduling method comprising:

• in response to a domain name resolution request of a business application, forwarding the domain name resolution request to a central domain name system, wherein the domain name resolution request carries a target domain name of the business application, the central domain name system is configured to forward the domain name resolution request to a target egress gateway corresponding to the target domain name, and the central domain name system is preconfigured with gateway information of egress gateways corresponding to a plurality of domain names;
• receiving a first target network address and a gateway address of the target egress gateway that are fed back by the central domain name system, wherein the first target network address is obtained by the target egress gateway by sending the domain name resolution request to a corresponding first domain name resolution server for domain name resolution;
• performing network address translation on the first target network address to obtain a virtual network address;
• and
• performing data transmission based on the virtual network address, the gateway address, and the first target network address.
