The TCP/IP network services database contains information about TCP/IP
server applications such as name, port, and protocol. This information
is used by the getservbyname and getservbyport TCP/IP
socket APIs, which allow you to retrieve the socket application port by
passing the name and vice versa.
The TPF system supports an extended network services database.
TCP/IP network services database support allows you to:
- Define quality of service (QoS) properties, including a differentiated
services codepoint value for outbound messages.
- Define a weighting factor to allow messages for each application to be
weighted differently when using data collection.
- Note:
- The TCP/IP network services database is not a replacement for the Internet
daemon. The application definitions in the TCP/IP network services
database are independent from the definitions in the Internet daemon
configuration file (IDCF); therefore, you need to define an application
in both places if you want the Internet daemon to manage the application and
if you want to also collect statistical data for the application. See Operator Procedures for the Internet Daemon for more information about the Internet daemon and the
IDCF.
