Problems solved by technology

[0005] The main purpose of the present invention is to provide a broadcast request response method, system and terminal customized based on the DHCP protocol, to overcome the lack of customization and flexibility of the existing response method based on the DHCP protocol when processing broadcast requests, and to solve the existing problems. There is a technical problem that a large amount of network resources are consumed due to sending DHCP packets to clients whose MAC addresses do not match.

Embodiment 1

[0054] refer to figure 1 , figure 1 A flow chart of an embodiment of a broadcast request response method based on DHCP protocol customization provided by the present invention is shown. It includes: step S110, step S120 and step S130.

[0055] In step S110, the broadcast request sent by the client is received.

[0056] Specifically include: a DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) server responds to a DHCP DISCOVER packet sent by a client in a broadcast manner.

[0057] As a preferred embodiment, the client sends a PXE (preboot execute environment, pre-boot execution environment) request in a broadcast manner, and the PXE request carries a DHCP DISCOVER packet; the DHCP server captures the DHCPDISCOVER packet.

[0058] In step S120, the MAC (Media Access Control or Medium Access Control) address of the client carried in the broadcast request is filtered.

[0059] include:

[0060] Filter the client MAC address in the DHCP DISCOVER ...

Embodiment 2

[0070] refer to image 3 image 3 A structural block diagram of an embodiment of a broadcast request response system 200 based on DHCP protocol customization provided by the present invention is shown. include:

[0071] The receiving module 21 is configured to receive the broadcast request sent by the client.

[0072] The filtering module 22 is configured to filter the client MAC address carried in the broadcast request. and.

[0073] The matching module 23 is configured to match the MAC address of the client with the MAC addresses stored in the database, respond to the broadcast request after the matching is successful, and send prompt information to the client after the matching fails.

[0074] Further, refer to Figure 4 , the receiving module 21, comprising:

[0075] The DHCP server receiving unit 211 is configured to respond to the DHCP DISCOVER packet sent by the client in a broadcast manner.

[0076] As a preferred embodiment, the client sends a PXE (preboot exec...

Embodiment 3

[0094] refer to Figure 9 , Figure 9 A structural block diagram of an example of a customized broadcast request response terminal 300 based on the DHCP protocol provided by the present invention is shown. It includes the system 200 described in any one of the second embodiment.

[0095]Embodiment 3 of the present invention receives the broadcast request sent by the client; filters the client MAC address carried in the broadcast request, and matches the client MAC address with the MAC address stored in the database; Broadcast request, the technical solution of sending prompt information to the client after the matching fails, overcomes the lack of customization and flexibility of the existing response method based on the DHCP protocol when processing broadcast requests, and solves the mismatch of MAC addresses in the prior art The client sends a DHCP message to cause a large amount of network resource consumption. The broadcast request received by the DHCP server checks that...

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 [0001] The invention relates to the technical field of communication, is aimed at modifying the DHCP protocol, matches a response mode according to the MAC address of the broadcast request, and in particular relates to a broadcast request response method, system and terminal customized based on the DHCP protocol. Background technique [0002] DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) is a LAN network protocol, using the UDP protocol to work, there are two main purposes: to automatically assign IP addresses to internal networks or network service providers, to users or internal network administrators As a means of centrally managing all computers. DHCP has 3 ports, among which UDP67 and UDP68 are normal DHCP service ports, serving as service ports of DHCP Server and DHCP Client respectively; port 546 is used for DHCPv6Client, not for DHCPv4, and serves for DHCP failover, which requires special The enabled service, DHCP fa...
