| Abstract | During the past decade, we have witnessed the deployment and evolvement of broadband networks and mobile networks growing at an unprecedented pace, which has enabled many new applications and services, ranging from IPTV to telepresence, from interactive online games to cloud computing, and from mobile video streaming to mobile social networks. This imposes many challenges and leads to the rising demand for many aspects of computer networks and communications, including greater network bandwidth, more reliable and secure network connection, more optimal resource allocation across the network, more efficient cross-layer network architecture design, and higher quality of service and experience by consumers. The twentieth International Conference on Computer Communication Networks (ICCCN) is one of the leading international conferences for presenting novel ideas and fundamental advances in the fields of computer communications and networks. It covers a very wide range of topics including next-generation computer network architectures and protocols (broadband, sensor networks, optical and grid networking, wireless ad hoc networks, mesh networks), network algorithms and performance evaluation, content networking and multimedia delivery technologies, network security and privacy, as well as Internet applications and services. In 2011, the main conference attracted a record 452 submissions of which 134 high quality regular papers (also a record) were accepted for presentation. In view of the success of ICCCN 2011, this special issue on the advances in communications and networking is dedicated to this conference. We invited the authors of the very top papers to submit full journal papers by extending the conference version with a substantial amount of new content, including new analytical and experimental results and more thorough discussions. These extended papers, to appear in two issues of the journal, have been separately reviewed to ensure that they have met the journal’s standards. In the following, we briefly summarize the papers included in this special issue. Design of efficient network algorithms is one of the fundamental issues in computer networking. There are five papers in this area addressing the analysis, measurement, and simulation tools for evaluating the behavior and performance of complex communication networks. In “Scalable network emulation - the NET approach”, A. Grau, K. Herrmann, and K. Rothermel develop a Network Emulation Testbed (NET) system which is able to achieve high scalability by combining efficient node virtualization and adaptive virtual time. In “Authenticated quality-of-service signaling for virtual networks”, R. Bless, M. Röhricht, and C. Werle present a Virtual Link Setup Protocol (VLSP) that is designed as a modular extension to a standardized state-of-the-art signaling protocol suite. They use these signaling protocols to ensure an authenticated on-demand setup of virtual links with the establishment of Quality-of-Service guarantees in the underlying substrate. Redundancy detection is widely used in the storage, management, and transmission of digital content. In “Low-overhead dynamic sampling for redundant traffic elimination”, E. Halepovic, C. Williamson, and M. Ghaderi propose a dynamic sampling algorithm for redundant content detection algorithm, which is self-configuring and can precisely match the specified sampling rate. Furthermore, it offers byte savings comparable to the static algorithm, with very low additional processing overhead. In “Performance isolation in network and computing systems with multiple inputs”, J. Brassil proposes a novel analytical measure of performance isolation for shared resource systems serving multiple traffic flows or computing workloads. By basing the proposed isolation measure on well-known results from network calculus, he demonstrates how isolation metrics can be calculated for flows traversing both individual system elements and networks of those elements. Proactive failure management is a crucial technology to characterize system behaviors and forecast failure dynamics in the cloud. In “Ensemble of Bayesian predictors and decision trees for proactive failure management in cloud computing systems”, Q. Guan, Z. Zhang, and S. Fu present an unsupervised failure detection method using an ensemble of Bayesian models, which achieves high true positive rate and low false positive rate for proactive failure management based on experiments in an institute-wide cloud computing system. Although new wireless network technologies and video delivery mechanisms such as IEEE 802.11 (Wi-Fi) and the 3G and 4G cellular systems are becoming strong alternatives to their wired counterparts, reliable communication in wireless networks is still very challenging and critical. In “Prioritized information recovery for wireless link-layer communication” S. Soltani and H. Radha develop Prioritized Automatic Code Embedding (PACE) link-layer protocol to achieve preferred data recovery order across connections, while maintaining stable and reliable data flows over wireless networks. The area of computer communications and networking being so broad, we can only cover a limited number of papers in this special issue. However, these papers have addressed a good range of topics from network architecture to algorithms, emulations, and security, from the study of multimedia delivery architecture to biometrics. We hope these papers included in the special issue will provide readers with insight into the state-of-the-art technologies, challenges, and trends concerning next generation network architectures, protocols, applications, and services. We also hope they can be a catalyst for further research in improving communications and networking through scientific and technological innovation. We thank all the authors for their high-quality contributions to this special issue. We would like to send our sincere thanks to the staff at the JCM Academy Publisher for their efficient job in handling the manuscripts. Our genuine gratitude also goes to the Associate Editor-in-Chief of the JCM Journal of Communications, Dr. Haohong Wang, for his assistance with this special issue.
