Problems solved by technology

[0004] In the DHCP relay anycast scenario, multiple relay devices present the same IP address to the DHCP service side, so the response message may be sent to other relay devices, and the other relay devices send the response message to the sending address request message The relay device of the message will cause the forwarding path of the response message to be detoured

Embodiment Construction

[0053] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0054] In order to facilitate the understanding of the embodiments of the present application, the concepts of the nouns involved are firstly introduced below:

[0055] DHCP is a protocol for dynamically managing and configuring client IP addresses (such as IPv4 addresses, IPv6 addresses, etc.).

[0056] Anycast is to assign an IP address to hosts in different physical locations on the same network, and packets sent to this host are routed to the "nearest" host by the network.

[0057] DHCP relay anycast scenario, in this scenario, the client accesses multiple relay devices, and the IP addresses of the access sides of the multiple relay devices are the same; multiple relay devices present one The device, that is, the IP address ...

Abstract

The invention provides a method and device for sending a response message, computing equipment and a storage medium, and belongs to the technical field of network communication. The method comprises the steps that a network device receives a response message sent by a DHCP service device, wherein a destination address of the response message is a first IP address of a relay device, and the relay device establishes a communication connection with a client; the network device determines a first next hop address in a plurality of next hop addresses corresponding to the destination IP address of the response message, wherein the first next hop address is a first tunnel endpoint IP address of the relay device and being different from tunnel endpoint IP addresses of other relay devices of a target anycast group to which the relay device belongs, and each relay device in the target anycast group establishes a communication connection with the client; and the network equipment can forward the response message to the relay equipment according to the first next hop address. By adopting the method and the device, the detour condition of the response message can be reduced.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a method, device, computing device and storage medium for sending a response message. Background technique [0002] The Dynamic Host Configuration Protocol (DHCP) is a protocol for dynamically managing and configuring the client Internet Protocol (IP) address. The IP address includes the fourth version of the Internet Protocol (Internet Protocol Version 4th, IPv4 ) addresses and Internet Protocol Version 6th (IPv6) addresses. With the expansion of network scale and the development of network technology, the application of DHCP is becoming more and more extensive. DHCP can be applied to the DHCP relay anycast (relay anycast) scenario. In this scenario, the client accesses multiple relay devices (that is, gateway devices), and the IP addresses of the access sides of the multiple relay devices are the same. Yes, multiple relay devices present one device ...
