The 5^th International Conference on Queueing Theory and Network Applications (QTNA 2010) was held at Beijing Jiaotong University in Beijing, China, on July 24-26, 2010. It is a continuation of the series of successful conferences - QTNA2006 (Korea), QTNA2007 (Japan), QTNA2008 (Taiwan), QTNA2009 (Singapore). The theme of QTNA2010 is “Enhancing the coherence between theory and applications”. QTNA2010 is a conference for the dissemination of state-of-the-art research and its applications in networks and related issues. The aim of the conference is to bring together researchers, scientists and practitioners from the world to identify important and challenging problems and issues in the area of queueing theory and network applications and work together to discover feasible solutions for these problems. The conference will cover all the key topics in queueing theory, communication networks and other related areas. It will provide an in-depth representation of theory and practice in these areas. Each submission should promote queueing theory or related techniques, and demonstrate a relationship between theory and its application; any topic that satisfies these two requirements would be of interest.   
      The Co-Chairs of Organizing Committee are Professor Jinting Wang from Beijing Jiaotong University and Wuyi Yue from Konan Univ., Japan. The Co-Chairs of Steering Committee are Professors Bong Dae Choi (Korea), Yutaka Takahashi and Wuyi Yue (Japan).
