Avaya VTCPD Features
The Avaya VTCPD process facilitates communication between application programs
(PeriProducer) and one or more external hosts.
The PeriProducer applications see the Avaya VTCPD daemon as a resource, with a
configurable name. The applications use the PeriProducer resource blocks to provide
the GET, FREE, SEND RESOURCE, and RECEIVE RESOURCE functions. The
following table correlates specific VRAM code to PeriProducer blocks:
The external hosts see the Avaya VTCPD daemon as a configurable host resource and
communicate through the daemon’s TCP/IP or UDP connections.
The Avaya VTCPD daemon can connect with one or more external hosts and
accommodates a wide variety of application requirements and host configurations.
The daemon can also be used to monitor the elapsed time on any outstanding request
and also provides a timing utility for applications.
One limitation is that a Avaya VTCPD daemon can run only one protocol at time. It
can connect to several hosts using the same protocol, but if a new protocol is required
another Avaya VTCPD process must be started for the new protocol.
Configurations Include:
• Connection to multiple VMST processes
• One or more connections to a single host
• Multiple connections to multiple hosts
• Connections to (yet-to-be-specified) hosts and port numbers
• Multiple Avaya VTCPD daemons with one or more hosts (one connection per
line)
Avaya VTCPD can also be configured to automatically switch to a secondary host, in
the event of a primary host failure.
