This paper presents the experimental results in applying formal methods to an industrial protocol for constraint-based path computation, called Path Computation Element Communication Protocol (PCEP). A number of major activities in model-based testing are included in the experiments from modeling to test generation where PCEP is described in the IF language and a number of tools are used for validation, verification, and test generation. As a result, some errors and ambiguities have been found in the PCEP standard specification. Copyright © 2011 John Wiley & Sons, Ltd.
