Simple Protocol

Abstract

This is a small toy example describing a simple protocol by which a sender can transfer a number of packets to a receiver. The communication medium may loose packets and packets may overtake each other. Hence, it may be necessary to retransmit packets and to ignore doublets and packets that are out of order.

The example illustrates how the results of a lengthy simulation can be recorded for later inspection and analysis. One way is to use the "Save Report" command, a second to add "reporting places", a third to use an output file, and a fourth to use charts.

The example is a modified version of a timed CP-net presented in Sect. 5.5 of Vol. 2 of the CPN book.
