TCP/IP Connections

The trusted host and Policy Server communicate across TCP/IP connections. The number of available TCP/IP connections between the trusted host and Policy Server is determined by the available sockets for the Policy Server's authorization, authentication, and accounting ports.

The number of sockets per port controls the number of simultaneous threads accessing the Policy Server from the Web server. Each user access request is handled by a separate Web server thread, which requires its own socket. The Web server maintains a pool of threads for requests and only creates a new one when there are no more available threads. As traffic increases, the number of sockets per port needs to increase.

There are several settings that affect the TCP/IP connections between the trusted host and the Policy Server.

Note: More information about these values and how you may have to adjust the values as your SiteMinder environment grows exists in the Policy Server Administration Guide.
