f5 load balancing algorithms

Load balancers are often referred to as four-tier switches or seven-tier switches. The four-layer switch mainly analyzes the IP layer and the TCP/UDP layer to achieve four-layer flow load balancing. In addition to supporting four-tier load balancing, the seven-tier switch al

This blog reposted from: http://blog.csdn.net/u014649204/article/details/25115039 The design of the balancing algorithm directly determines the performance of the cluster in load balancing. Poor design of the algorithm will lead to load imbalance in the cluster. The main task of the general

division based on the current load status of the system is called dynamic load balancing. Load imbalance is mainly caused: The iteration size of some algorithms is not fixed, but the iteration size can be obtained during compilation; The iteration size of some

will be the request for this service IP all directed to Dr, and Dr received the packet according to the scheduling algorithm, to find the corresponding realserver, Change the destination MAC address to Realserver's Mac and send it to this realserver? At this point, the Realserver receives this packet, it is equal to receive the packet directly from the client, the processing is returned to the client directly? Because Dr wants to change the two-layer header, So the DR and Realserver must be in
