Problems solved by technology

[0020] As can be seen from the above scheme, in order for the DHCP client to obtain a dynamically allocated IP address from the DHCP server through the DHCP relay, the DHCP relay and the DHCP server need to perform multiple communication interactions, resulting in the DHCP client receiving the IP address from the DHCP server through the DHCP relay. Obtaining a dynamically assigned IP address takes too long and is inefficient

Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail by giving specific embodiments and referring to the accompanying drawings.

[0045] In the present invention, in order for the DHCP client to obtain the dynamically assigned IP address through the DHCP relay, the DHCP relay and the DHCP server only perform one communication interaction, and the DHCP client is filled with more than one gateway IP address configured by the DHCP relay. In the configuration request message of the client, send it to the DHCP server. After receiving the configuration request message, the DHCP server determines which gateway IP address the gateway IP address of the subnet to which the DHCP client belongs to is the gateway IP address filled in the configuration request message according to the information of the DHCP client carried in the configuration request message. The DHCP client is a...

Abstract

The invention discloses a method for DHCP (dynamic host configuration protocol) relay to request IP address for DHCP client end, comprising: A. DHCP relay receives configuration request message sent by DHCP client end by broadcast, and adds above one gateway IP address or network segment address to the configuration request message and then sends the message to DHCP server; B. DHCP server determines gateway IP address or network segment address of the subnetwork the DHCP client end belongs to, by the added gateway IP address or network segment address in the request message, and allocates an IP address in a corresponding address pool to the determined gateway IP address or network segment address to the DHCP client end and transmits the allocated IP address through the DHCP relay to the DHCP client end. And the method only requires the DHCP relay and DHCP server make one communication interaction in the course that the DHCP client end obtains dynamic allocated IP address by DHCP relay, saving time and raising efficiency.

Description

technical field [0001] The invention relates to a technology for a Dynamic Host Configuration Protocol (DHCP) server to assign an IP address to a DHCP client, in particular to a method for a DHCP relay to request an IP address from a DHCP server for a DHCP client. Background technique [0002] With the expansion of network scale and the improvement of network complexity, the configuration of the network becomes more and more complicated, and the problems that the location of the client changes and the number of clients exceeds the assignable Internet Protocol (IP) addresses often occur. In order to solve the above problems, DHCP technology has emerged. A server using DHCP technology (hereinafter referred to as the DHCP server) can dynamically allocate IP addresses to DHCP clients currently connected to the network, so that the DHCP clients currently connected to the network can pass the assigned The IP address receives the service of the network. [0003] The early DHCP pro...
