Abstract

See full text

The real-time aspects of keep-alive generation are removed from the dynamic routing protocol (DRP) application and are embedded within a Unix-based operating system, which is programmed by DRP. A keep-alive control provides the ability to create a keep-alive message and a timeout interval on a TCP socket. Each socket can have an independent keep-alive message and timeout interval. A keep-alive message is sent whenever the TCP socket sends no normal user output for a duration exceeding the timeout interval. A timeout interval is normally specific in seconds and a keep-alive message is user definable and must not exceed a predetermined length in bytes. System calls are used to set the timeout interval and keep-alive message independently. Both a timeout and a keep-alive message must be set before the timeout becomes active.
