[0003] Here's how a network load balancer works:

[0004] The network load balancer first receives the request from the client;

[0005] Then, the network load balancer will distribute the request to multiple servers according to certain strategies;

[0006] Finally, the server processes the client's request and returns the processing result to the client. The network load balancer can improve the overall performance and reliability of the network and is an important part of the network infrastructure.

[0007] In order to prevent dust from forming inside the existing load balancer, filters are installed on the outside of the air inlet and outlet for heat dissipation of the load balancer to prevent dust from entering.

During the later maintenance process, the filter set on the inside needs to be replaced. The load balancer needs to be pulled out of the rack for a distance for replacement, which is rather troublesome. Therefore, a network load balancer is proposed to address the above problem.
