Problems solved by technology

This method puts a lot of pressure on the core device DHCP-Server that has already undertaken a large number of user authentications, especially when a core device goes down and a large number of new users come online. Each new user sends a DHCPdiscover message, and the DHCP-Server must poll the address pool. Once, causing DHCP-Server performance bottleneck
As a result, a large number of new online users in the entire network cannot obtain dynamic IP addresses and authentication correctly in real time

Embodiment 1

[0047] This embodiment is applied in an Ethernet multi-ring protection technology ERPS ring network composed of 2N+1 core devices, wherein one core device is used as a redundant backup machine for all other core devices, and other Two sets of 2N core devices form N hot standby groups. Each hot standby group has two pairs of VRRP groups. The two core devices in the hot standby group are the master devices of the two pairs of VRRP groups. Each VRRP The group is configured with a virtual gateway address, the redundant standby machine is configured with a real gateway address, and one of the hot standby groups is configured as a DHCP server, and each gateway is configured with an address pool, and N is an integer greater than 1. This embodiment provides a The processing flow of the deployment method of network device load balancing is as follows: image 3 shown, including the following steps:

Embodiment 3

[0077] This embodiment provides a system 40 for realizing load balancing of network equipment, as shown in the appended Figure 6 As shown, it includes: Ethernet multi-ring protection technology ERPS ring network composed of 2N+1 core equipment, in which one core equipment is used as a redundant standby machine for all other core equipment, and other 2N Every two sets of core devices form N hot standby groups. Each hot standby group has two pairs of VRRP groups. The two core devices in the hot standby group are respectively the master devices of the two pairs of VRRP groups. Each VRRP group Configure a virtual gateway address, the redundant standby machine configures a real gateway address, wherein a hot standby group is configured as the DHCP server 41, and each gateway is provided with an address pool, and N is an integer greater than 1;

[0078] The DHCP server 41 is configured to receive the DHCP request sent by the client and carry the virtual gateway address information ...

Abstract

An embodiment of the invention provides a method, a system and a DHCP server for realizing load balance of network equipment. The method , the system and the DHCP server are applied in an Ethernet ring protection switching (ERPS) ring network which is composed of (2N+1) sets of core equipment. The method comprises the following steps of receiving a DHCP request which is transmitted by a client and carries virtual gateway address information that corresponds with a VRRP group by the DHCP server; when the total number of the IP addresses which are already distributed to an address pool that corresponds with the virtual gateway address information does not reach a threshold, performing feedback of the IP address to the client according to the address pool which corresponds with the virtual gateway address information; and when the total number of the IP addresses which are already distributed to the address pool that corresponds with the virtual gateway address information reaches the threshold, performing feedback of the IP address to the client according to the address pool which corresponds with real gateway address information. Therefore problems of performance bottleneck of the core equipment and incapability of realizing real-time networking of new users are settled.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method, a system and a DHCP server for realizing load balancing of network equipment. Background technique [0002] In recent years, with the rapid development of Internet technology, informatization construction is no longer limited to fixed places, and mobile places such as transportation vehicles also have great potential and markets, such as subways, trains, and buses. As a fast, comfortable, and large-capacity new type of transportation, the subway has become a part of the life of metropolitan groups, and the multi-functional needs of the masses for the subway have become increasingly prominent. Especially with the popularization of smart phones, people have a serious dependence on the public network. Therefore, the digital construction of the subway is imminent and has become the living needs of the vast majority of people. The network experience anytime, anywhere a...
