firewall load balancing

Recent projects have encountered a firewall load balancing needs, take out and discuss with you. Users in the project procurement of 4 domestic well-known brands of high-end firewall, originally intended to use the firewall itself cluster way to achieve the

, many networks were designed to rotate domain names, that is, one domain name corresponds to multiple servers. As a cheap solution, domain Name rotation can solve some server load problems. However, this load balancing method has many limitations: it cannot be based on the load of each server, send user service reques

In a network with Network Load Balancing (NLB) deployed, when a customer initiates a connection request against an NLB virtual address, NLB determines the NLB node for the customer service through some NLB algorithm, usually determined by the client source address at which the request originated. Before the NLB node changes, for a customer, it will always be serviced by a corresponding NLB node. Integrated

lower-level settings, usually more efficient, but with limited application scope; The seven-tier model requires more resource loss and is theoretically more powerful than a four-tier model, and today's implementations are more based on HTTP applications.Four, load Balancing Technology Program DescriptionThere are many different load

and is theoretically more powerful than a four-tier model, and the implementation is now more based on HTTP applications.Four, load Balancing Technology Program DescriptionThere are many different load balancing techniques to meet different application requirements, from the device objects used in

domain name ); Third, when one or more servers in the network load balancing are unavailable, the service will not be interrupted. When the Network Server Load balancer automatically detects that the server is unavailable, it can quickly re-assign Client Communication to the remaining servers. This protection can help you for critical businessProgramProvides u

we are talking about Load balancer, sometimes called a four-tier load balancer or seven-tier load balancing device, sometimes called a four-layer switch or seven-layer exchange. The four-layer load balancing device mainly analyzes

What is LVS??? Let's start with a brief introduction to LVS (Linux Virtual Server), which is actually a cluster (Cluster) technology that uses IP load balancing technology and content-based request distribution technology. The scheduler has a good throughput rate, transfers the request evenly to the different server execution, and the scheduler automatically shields off the server's failure, thereby forming
