Server load balancing devices use Predictor technology and advanced configurable application combinations to achieve the expected flow distribution results. The Predictor technology is the lower layer technology, which uses the statistical allocation method to divide the data flow of the arrival server.Further enhancements enable SLB to forward traffic based on higher-level HTTP protocol information.

) connections are the opposite, each connection is identified by the Server Load balancer IP (MIP: mapped IP) and a random port. That is: MIP: randomport-> realserverip: 80 In this case, the Server Load balancer acts as a client and its port is limited by the maximum number of TCP/IP Ports 64 K (65536). Therefore, you can only create a server connection (server connnections) of up to 64 K ). The bottleneck is likely to occur on the server connection of the Server Load balancer. In this case, how

However, it is not possible to define rules freely, and it is troublesome to change a mapped IP or machine failure, and there is a problem with the delayed DNS entry.5.
