From IPv4 to IPv6: the case of OpenH323 library

We discuss our experience form porting the OpenH323 platform to IPv6. We briefly discuss the structure of the platform, and we present the various problems we faced and choices we made, regarding the easiest approach to the porting procedure, the compatibility with earlier, IPv4-only versions of the platform, the existence of tools that could aid us with the porting task and the verification of results. We believe that the results of our effort can serve as guidelines for other similar projects and we present a general methodology which might be applicable to similar porting projects.
