All URL requests come in to a single, virtual IP address. Using Resonate's Resource-based Scheduling technology, Dispatch is the first solution to use all information contained in a URL request to make intelligent scheduling decisions. The Dispatch Scheduler matches the requested resource with the set of servers capable of responding. Once the set of appropriate servers has been identified, a configurable load-balancing policy is used to select the least busy server among the set. Since Dispatch can match the specific resources being requested with servers that are capable of responding, Web masters can functionally segregate Web content across servers and optimize performance.
Dispatch can also schedule requests to servers regardless of their location.
Servers can be located across networks and departments making Dispatch an ideal DSM solution for Electronic Commerce sites with resources located behind firewalls and for intranets with servers and content distributed throughout the corporation. Critical Web content can be replicated across servers for high availability where needed. Dispatch provides immunity to server failures by recognizing when a server has failed and dynamically directing traffic to other servers capable of responding. Resonate Dispatch also includes a Java-based Manager to simplify administration of the site. The Dispatch Manager can run on any Java-capable machine located anywhere on the network.
