Configuring NameServers : Configuring fault tolerance and load balancing : Load balancing

Load balancing

If you specify a priority weight factor for each Unified Broker instance, the NameServer distributes the connection requests proportionately, thus balancing the load. For example, suppose that an Inventory service is supported by WebSpeed brokers WS1, WS2, and WS3, which have weight factors of 20, 20, and 60, respectively. The selection algorithm used by the NameServer guarantees that WS1 and WS2 are selected 20% of the time and WS3 is selected 60% of the time.
Note: You do not assign application services or weight factors to NameServers, but rather to Unified Broker instances. Each Unified Broker instance passes its weight factor and list of application service names to its controlling NameServer when it registers with the NameServer.
