Abstract: This article discusses the Server Load balancer technology and load allocation strategies used by distributed network servers, and implements the Server Load balancer gateway on FreeBSD Based on Network Address Translation, it is applied to our Internet
When developing large network applications, sometimes a server cannot meet the requirements of the client. In this case, you can only add servers to solve the problem, that is, use multiple servers to balance the network load. By using network load balancing, multiple servers are published to the network with one IP ad

But if the site has an average of more than 200 requests per second, then the problem is: This is already the best Web server, what should I do? The same scenario applies to the database. To solve this problem, we need to understand the principle of "load balancing".

To improve server performance and workload, enterprises usually use DNS servers, network address translation, and other technologies to achieve multi-server load balancing, many of them use several servers to achieve Load Balancing

The interaction between the DHCP Client and the DHCP Server involves both broadcast packets and unicast packets (used during renewal, we know that the general Server Load balancer equipment implements Load Balancing for unicast packet data, so the pure DHCP Clien
