Usage Guidelines

Extreme Networks GlobalPx Content Director
ª
is a DNS-based Internet trafÞc-management system.
This system allows you to take advantage of network and server resources regardless of their location
on the Internet or your Intranet. As you add points of presence (POPs, clusters of one or more Px-series
switches) to a network, GlobalPx Content Director monitors server loads and network response
latencies, distributing client requests to the POP that it determines will deliver the best performance.
GlobalPx Content Director improves client access performance and reliability by leveraging dispersed
network resources.
The GlobalPx Content Director transparently directs clients and client DNS servers to the most
appropriate POP to satisfy client requests. Typically, the physically closest POP is the one that gives the
fastest response. However, this is not always the case. The GlobalPx Content Director scheduler routes
requests to the optimal POP. The scheduler is a separate program that runs on a Windows or Solaris
machine. When the scheduler is in use, virtual services are not automatically used by the scheduler. You
must issue this command for any virtual service that you want to be used by the scheduler. You must
also conÞgure the service in the scheduler itself. For more information, see the GlobalPx Content Director
Installation and User Guide.
You must use the build command to commit the conÞguration changes made by this command.
