-4 switch stores a source IP address that matches the selected server and a connection table associated with the source TCP port. The layer-4 switch then forwards the connection request to the server. All subsequent packets are reinjected and forwarded between the client and the server until the switch discovers a session. When layer-4 switching is used, the access can be connected to a real server to meet user-defined rules, for example, the number of connections on each server is equal or the

In fact, as early as more than 10 years ago, also in the harbor to do four layers of exchange, he has been concerned about load balancing, but the market capacity is relatively small. After 2010 years, the domestic market capacity began to rise, almost to 1.5 billion of the scale, at the same time, a number of mainstream players i

Such programs typically use a specific runtime library, such as an MPI library designed for scientific computing.HPC clusters are particularly well suited for computing jobs where large amounts of data are communicated between compute nodes in a calculation, such as the intermediate results of a node or the results that affect other nodes.Common cluster hardware and softwareCommon open source Cluster software is: lvs,keepalived,haproxy,nginx,apache,heartbeatCommon business cluster

Server Load balancer is a technology that implements Load Balancing through an algorithm. In layman's terms, requests are uniformly distributed to devices,Server Load balancer will receive all requests in a unified manner, and then distribute these requests to the server Load balancer group according to the configured algorithm.All members to achieve balanced allocation of requests (loads.F5 is a brand of Server Load balancer. Its position is similar to that of Nokia's mobile phone brand.Apart f

Install and configure Nginx in LinuxApplication scenarios For a large website, Server Load balancer is an eternal topic. As its name suggests, Server Load balancer distributes loads to different service units, ensuring service availability and fast response, provide a good user experience. With the rapid development of hardware technology, more and more Server Load balancer hardware devices are emerging, such as F5 BIG-IP, Citrix NetScaler, and Radware
