Load-Balancing MethodAs one NAS machine reaches its optimal handling capacity, subsequent requests are sent to another NAS machine with duplicate application components. With multiple servers handling requests, response time increases.
|
Per Component |
The Per Component value maintains response-time statistics for each application component. |
Per Server |
The Per Server value calculates response time for the entire server. |
When a Netscape Application Server evaluates itself, it then broadcasts the information. This broadcast is sent to a multicast IP address and port number held in the registry.
By listening for the broadcasts of other NAS and considering its own information, a NAS creates a load-balancing table. This table is under constant reconstruction as information is updated and processed.
Server Load |
The hardware resources of the machine that houses the Netscape Application Server are evaluated. The four components evaluated are CPU, memory, Disk I/O, and number of requests in the queue. |
Application Component Criteria |
There are four criteria for Application Component performance:
