Abstract
The invention provides a broadcast request response method based on DHCP protocol customization, a system and a terminal thereof. The method comprises the following steps of receiving a broadcast request sent by a client; filtering a client MAC address carried by the broadcast request, matching the client MAC address with a MAC address stored in a database; and after matching is successful, responding to the broadcast request, and after the matching is failed, sending prompt information to a client. By using the broadcast request response method based on the DHCP protocol customization, the system and the terminal thereof, a defect that an existing response method based on a DHCP protocol, which is used to process the broadcast request, possesses poor customization performance and flexibility is overcome; and a technical problem that a lot of network resources are consumed because a DHCP message is sent to a client which does not match with the MAC address in the prior art is solved. A DHCP server receives the broadcast request, verifies that the MAC address does not match and does not reply a DHCPOFFER package so that network resource consumption is reduced.
Description
Technical field
The present invention relates to communication technical field, is the modification for DHCP protocol, matched according to the MAC Address of broadcast request
A kind of response mode, more particularly to a kind of broadcast request response method, system and terminal customized based on DHCP protocol.
Background technology
DHCP (Dynamic Host Configuration Protocol, DHCP) is a local
The procotol of net, is worked using udp protocol, mainly has two purposes：Automatically divide to internal network or Internet service provider
With IP address, to user or internal network manager as the means that all computers are made with central management.DHCP has 3 ends
Mouthful, wherein UDP67 and UDP68 is normal DHCP service port, respectively as the clothes of DHCP Server and DHCP Client
Business port；No. 546 ports are used for DHCPv6Client, rather than DHCPv4, are serviced for DHCP failover, and this is to need
The service especially to open, DHCP failover are for doing " two-node cluster hot backup ".
In prior art, based on response method of the DHCP protocol when broadcast request is processed as shown in figure 1, the method bag
Include：Dhcp client sends broadcast request into LAN, and Dynamic Host Configuration Protocol server end receives the broadcast request, and responds the broadcast
Request, distributes IP, gateway, mask, rental period etc. to client.
Inventor has found in the course of the study, the response in prior art based on DHCP protocol when broadcast request is processed
The customization of method and motility shortcoming, still respond in the case of MAC Address is unmatched, unmatched to MAC Address
Client sends the caused a large amount of consumption of network resources of DHCP message.
The content of the invention
Present invention is primarily targeted at provide it is a kind of based on DHCP protocol customize broadcast request response method, system and
Terminal, to overcome the customization of the existing response method based on DHCP protocol when broadcast request is processed and lacking for motility shortcoming
Fall into, in solving prior art, the caused a large amount of consumption of network resources of DHCP message are sent to the unmatched client of MAC Address
Technical problem.
