service primitive

Quick Reference

In a network layered architecture, when one layer requires another layer to carry out a service, the communication between the layers is carried out by service primitives. There are four categories of primitives: those that request a service, those that inform an entity that an event has occurred, those that represent responses to a service request, and those that confirm that the data associated with a request has arrived. So, for example, a layer that sends an email requests that the email is sent, is informed that this has taken place, receives data about the event, and responds to the event by signalling to another layer that the event has been successful.
