Network Dispatcher Load BalancingAvailability is crucial to handling Internet traffic. Slow responses or refused connections create unsatisfied users. Network Dispatcher has superior high availability, scalability, AND load balancing. The first generation of Web traffic load balancing, called round-robin DNS, had a domain name server (DNS) rotating traffic among a hard-coded list of IP address for Web application servers. This balancing is hardly optimal, since the DNS round-robin treats all the requests as equal, and does not take into account the availability of the servers and the workload on them. DNS also doesn't provide the ability to differentiate by port. Network Dispatcher is the next generation of server load balancing software. It can direct TCP/IP session requests to different servers belonging to a group of servers, automatically finding the optimal server to handle the request. Network Dispatcher also offers content-based routing, where requests are routed to specific servers depending on the content of the URL request. For HTTP traffic, this is accomplished by using Caching proxy. Rules-based BalancingRules-based balancing uses rules, and a set of servers among which to load balance, if the rule is obeyed. You can use this to fine-tune when and why packets are sent to which servers. Network Dispatcher reviews any rules you add from first priority to last priority, stopping on the first rule that it finds to be true, then load balancing the content between any servers associated with the rule. Network Dispatcher provides the following types of rules:
Balancing maximizes your hardware resources. Network Dispatcher provides a powerful, flexible, and scalable solution to peak-demand problems with Web servers. If this information is not displaying correctly, ensure your browser supports HTML 4.0 and Java applets, and is configured correctly. |
