The policy agent is a component in the TCP/IP stack that enforces policy
decisions regarding network resources, including access, connection load
balancing, and message prioritization. The TPF policy agent provides
the following functions:
- Connection load balancing by using the TPF Domain Name System (DNS)
server. See Domain Name System Support for more information.
- Packet filtering to verify that a particular remote client attempting to
access a TPF application is allowed to access that application. See Internet Security for more information about TCP/IP packet filtering firewall
support for the TPF system.
- Quality of service (QoS) support for differentiated services. See TCP/IP Network Services Database Support for more information about support for differentiated
services in the TPF system.
