The SDL Forum is held every 2 years and is one of the most important open events in the calendar for anyone from industry and academia involved in system design languages and modelling technologies. It is a primary conference for discussion of the evolution and use of these topics. The most recent innovations, trends, experiences and concerns in the field are discussed and presented. System and software modelling, specification, and analysis of distributed systems, embedded systems, communication systems, and real-time systems are addressed.
The SDL Forum Society that runs the Forum is a non-profit organization established by language users and tool providers to promote the Specification and Description Language (SDL), Message Sequence Charts (MSC) and related system design languages (including but not limited to UML, ASN.1, TTCN, SysML and URN), to provide and disseminate information on the development and use of the languages, to support education on the languages and to plan and organize the "SDL Forum" series and events to promote the languages.


In the last few years, we have witnessed a new level of convergence in the networked digital ecosystem. A large variety of embedded devices are becoming connected. The ever growing number of heterogenous devices connected demands highly available, scalable, secure and mobile services from the telecommunications and computer networks side. The complexity of network services on the other side is increasing at the same time. There are several emerging standards on this field, followed by numerous implementations. This result in time pressure both in standard implementations and product development cycles. So specification, design, validation, configuration, deployment and maintenance of such products are complex tasks. Thus, high quality modeling of these new systems with system design languages is essential.
