Connection Brokering

Connection Brokering directs client connection requests to the least-laden Siebel Server operating the desired component. Connection Brokering is an optional service of the Siebel Gateway that uses the Resonate Central Dispatch product to distribute (load-balance) Web-client connection requests from the Web server across multiple Siebel Servers. Only Web client requests to the Siebel Application Object Manager (such as the Call Center Object Manager) and Interactive Assignment Manager can be load-balanced by Resonate Central Dispatch.

NOTE:  Batch mode or background mode components are not load balanced by Resonate Central Dispatch. Nor are Mobile Web client connections distributed by Resonate Central Dispatch.

Impact of Failure

When the Resonate Central Dispatch Scheduler fails, current Web client user connections making use of the Scheduler will be interrupted immediately. No new Web client user sessions can be established to Siebel Servers. Although no immediate interruptions will occur to the Siebel Enterprise itself, no Web client users will be able to access the Siebel Enterprise using Resonate Central Dispatch.

High-Availability Solution for Connection Brokering

Two servers are specified as Resonate Central Dispatch Schedulers—one acts as the Primary Scheduler and the second acts as the Secondary Scheduler. The Primary Scheduler always listens on the Virtual IP (VIP) address and distributes traffic unless it at some point becomes unavailable, at which point the Secondary Scheduler takes over listening on the VIP and distributes traffic.

Resource Requirement for Connection Brokering

The Connection Broker/Resonate Central Dispatch Scheduler does not generally require many resources even when there is a heavy user load. Routing modules reside in the kernel layer or network driver layer.
