Proceedings of the 1st International Workshop on Worst-case Traversal Time

Willkommen in Wien, and welcome to WCTT 2011, the First International Workshop on Worst-case Traversal Time. The aim of the WCTT workshop is to gather together scientists and practitioners from both academia and industry to discuss methods for analysis of bounds on the traversal time in networked systems, multihop being a mandatory requirement. Traditionally, many tools and techniques have been available for computing worstcase bounds in multihop systems (e.g., Network Calculus, Real-Time Calculus, trajectory approach, event-based methods, formal methods, etc.), all exhibiting strong points. This provides a strong potential for cross-fertilization, which is what this workshop is aimed at. The WCTT workshop is held in conjunction with the 32nd IEEE Realtime Systems Symposium (RTSS). Realtime Systems are in fact becoming more and more networked systems, and the real-time research community is showing a growing interest in the topics dealt with in WCTT. We believe that this synergy is a winning one, as it gathers in the same place both the demand and the supply for solution methods to worst-case problems. In its first edition, WCTT has received nine submissions, which have gone through a blind review process. Each submission has received three reviews, and following a discussion, the TPC accepted eight papers. The workshop has been made possible thanks to the joint effort of many people, to which we are deeply thankful. Enrico Bini, workshop chair at RTSS, has been a valuable guidance throughout the whole setup process. Our TPC members have shown great commitment, and have helped us to gather what we believe to be an interesting program by providing excellent feedback to the authors. Finally, we want to thanks authors for submitting papers, and all of you for participating. We hope that you find the program stimulating and informative.
