The recompute interval works similarly. The server's recompute interval is 100ms.
Continuing with the example, the bandwidth gets recomputed periodically every
100 milliseconds. The calculation is based on the amount of traffic as well as the
metric interval.
At time 0 seconds, the bandwidth is calculated for the first time. The total traffic is
zero, divided by the metric interval of 30 seconds, gives a bandwidth of zero.
At 1 second, the bandwidth is calculated for the 10th time (1000 milliseconds/ 100
milliseconds). The total traffic is 5000 bytes, which is divided by 30 seconds. The
bandwidth is 5000/30 = 166 bytes per second.
At 30 seconds, the bandwidth is calculated for the 300th time. The total traffic is
5000 bytes, which is divided by 30 seconds. The bandwidth is 5000/30 = 166 bytes
per second.
At 32 seconds, the bandwidth is computed again for the 320th time. The traffic is
now 0 (since the one connection that generated traffic is too old to be counted),
divided by 30, gives a bandwidth of 0 bytes/second.
Setting Up Quality of Service
To configure the quality of service settings for a server instance or a class of virtual
servers, you need to configure the settings in through the user interface. To actually
enforce your quality of service settings, you must also set up Server Application
Functions (SAFs) in your
To configure quality of service, follow these steps:
From the Server Manager, click the Monitor tab.
1.
Click Quality of Service.
2.
A page appears listing general settings for quality of service, followed by a list
containing the server instance as a whole and each class of virtual servers.
To enable quality of service as a whole, click Enable.
3.
By default quality of service is disabled. Enabling quality of service increases
server overhead slightly.
Choose the Recompute Interval.
4.
The recompute interval is the number of milliseconds between each
computation of the bandwidth for all servers, classes, and virtual servers. The
default is 100 milliseconds.
