C H A P T E R 2 Prioritization and Policy Groups

Target Response Time Exceeded

Upon noticing a break in the target response time threshold, the

SA8250 scans the policy group’s active service and server pools for

shared resources. In this example, both the HTTP and HTTPS

services use Server 3. To provide the greatest server resources for the

highest priority service, shared resources are eliminated from

subordinate service pools (although each service will always have at

least one point of fulfillment). For example, in the figure above, new

HTTP connections are no longer sent to Server 3 in an effort to

guarantee the target response time for HTTPS. Server 3 will again

serve HTTP when target response times are met.
