Absrtact: This paper discusses the load balancing technology and load allocation strategy used by distributed network server, and realizes load balancing gateway on FreeBSD based on network address translation, which is applied to our Internet network server, and distributes

with Apache + mod_jk + Tomcat to achieve Tomcat The load balancing of the clusterIf there is a problem, you can use the CMD CD in the Apache installation file under the bin, run the httpd file, the error message will be printed out.The problem I have here is that the Include conf/mod_jk.conf cannot load the configuration file (this is the problem in English trans

Cache cluster system. It differs from the LBLC Algorithm in that it maintains a ing from a target IP address to a group of servers, while the LBLC algorithm maintains a ing from a target IP address to a server. The LBLCR scheduling algorithm maps "popular" sites to a group of Cache servers (server sets). When the request load of the "popular" site increases, the Cache server in the set is added, to process the increasing

hash scheduling algorithm.In the actual application, the source address hash schedule and the target address hash schedule can be used together in the firewall cluster, they can guarantee the unique entrance of the whole system. 9, shortest expected delay (shortest expected delay scheduling) abbreviation SED based on the WLC algorithm, illustrateABC three machines weigh 123 respectively, and the number of connections is 123,name if you use the WLC al

1 Initial knowledge Lvs:linux Virtual Server 1.1 LVs is whatLVS is the short name of Linux virtual server, which is a free software project initiated by Dr. Zhangwensong, and its official site is www.linuxvirtualserver.org. Now LVS is already part of the Linux standard kernel, Prior to the Linux2.4 kernel, the LVS had to be recompiled to support the LVS function module, but since the Linux2.4 kernel, the various functions of LVS have been built-in, without any patching of the kernel, and the fun

device in front of the cluster to achieve traffic distribution.Load Balancing (Balance), which means that load (work tasks, access requests) are balanced and distributed across multiple operating units (servers, components) for execution. is the ultimate solution for high-performance, single-point-of-failure (high availability), scalability (horizontal scaling).This article is the first article on

Four common methods for server load balancing in enterprisesIn order to improve the performance and workload of the server, enterprises usually use the technology of DNS server, network address translation and so on to realize multi-server load balancing, especially the Internet web sites of enterprises outside, many o

, thus providing the efficiency of the cache cluster system.　　5, the target address hash dispatch (Destination Hashing scheduling)The target Address hash schedule (Destination Hashing scheduling) algorithm is load balanced against the destination IP address, but it is a static mapping algorithm that maps a destination IP address to a server through a hash function.The target address hash scheduling algorithm first finds the appropriate server from a s

the policy, add the Snat policy, the source interface is the intranet port, the service pool references the service pool created in the previous step, the rest defaults, and the policy is started after completion.Port mappings:1, create service pool, type Select server, fill in the server IP, port to be mapped2, add the policy, the type is Dnat policy, the source address is 0 destination address for the external network IP, select the port, the extranet interface and reference the service pool
