The Eleventh International Conference on Networking and Services (ICNS 2015), held between May 24-29, 2015 in Rome, Italy, continued a series of events targeting general networking and services aspects in multi-technologies environments. The conference covered fundamentals on networking and services, and highlights new challenging industrial and research topics. Ubiquitous services, next generation networks, inter-provider quality of service, GRID networks and services, and emergency services and disaster recovery were also considered. IPv6, the Next Generation of the Internet Protocol, has seen over the past years tremendous activity related to its development, implementation and deployment. Its importance is unequivocally recognized by research organizations, businesses and governments worldwide. To maintain global competitiveness, governments are mandating, encouraging or actively supporting the adoption of IPv6 to prepare their respective economies for the future communication infrastructures. In the United States, government’s plans to migrate to IPv6 has stimulated significant interest in the technology and accelerated the adoption process. Business organizations are also increasingly mindful of the IPv4 address space depletion and see within IPv6 a way to solve pressing technical problems. At the same time IPv6 technology continues to evolve beyond IPv4 capabilities. Communications equipment manufacturers and applications developers are actively integrating IPv6 in their products based on market demands. IPv6 creates opportunities for new and more scalable IP based services while representing a fertile and growing area of research and technology innovation. The efforts of successful research projects, progressive service providers deploying IPv6 services and enterprises led to a significant body of knowledge and expertise. It is the goal of this workshop to facilitate the dissemination and exchange of technology and deployment related information, to provide a forum where academia and industry can share ideas and experiences in this field that could accelerate the adoption of IPv6. The workshop brings together IPv6 research and deployment experts that will share their work. The audience will hear the latest technological updates and will be provided with examples of successful IPv6 deployments; it will be offered an opportunity to learn what to expect from IPv6 and how to prepare for it. Packet Dynamics refers broadly to measurements, theory and/or models that describe the time evolution and the associated attributes of packets, flows or streams of packets in a network. Factors impacting packet dynamics include cross traffic, architectures of intermediate nodes (e.g., routers, gateways, and firewalls), complex interaction of hardware resources and protocols at various levels, as well as implementations that often involve competing and conflicting requirements. Parameters such as packet reordering, delay, jitter and loss that characterize the delivery of packet streams are at times highly correlated. Load-balancing at an intermediate node may, for example, result in out-of-order arrivals and excessive jitter, and network congestion may manifest as packet losses or large jitter. Out-of-order arrivals, losses, and jitter in turn may lead to unnecessary retransmissions in TCP or loss of voice quality in VoIP. With the growth of the Internet in size, speed and traffic volume, understanding the impact of underlying network resources and protocols on packet delivery and application performance has assumed a critical importance. Measurements and models explaining the variation and interdependence of delivery characteristics are crucial not only for efficient operation of networks and network diagnosis, but also for developing solutions for future networks. Local and global scheduling and heavy resource sharing are main features carried by Grid networks. Grids offer a uniform interface to a distributed collection of heterogeneous computational, storage and network resources. Most current operational Grids are dedicated to a limited set of computationally and/or data intensive scientific problems. Optical burst switching enables these features while offering the necessary network flexibility demanded by future Grid applications. Currently ongoing research and achievements refer to high performance and computability in Grid networks. However, the communication and computation mechanisms for Grid applications require further development, deployment and validation. The conference had the following tracks: Multi-technology service deployment and assurance CLOUD/GRID Networks and Services Emerging Network Communications and Technologies Next Generation Networks and Software Defined Networking The conference also featured the following symposium: • CONNET 2015, The International Symposium on Advances in Content-oriented Networks and Systems Similar to the previous edition, this event attracted excellent contributions and active participation from all over the world. We were very pleased to receive top quality contributions. We take here the opportunity to warmly thank all the members of the ICNS 2015 technical program committee, as well as the numerous reviewers. The creation of such a high quality conference program would not have been possible without their involvement. We also kindly thank all the authors that dedicated much of their time and effort to contribute to ICNS 2015. We truly believe that, thanks to all these efforts, the final conference program consisted of top quality contributions. Also, this event could not have been a reality without the support of many individuals, organizations and sponsors. We also gratefully thank the members of the ICNS 2015 organizing committee for their help in handling the logistics and for their work that made this professional meeting a success. We hope ICNS 2015 was a successful international forum for the exchange of ideas and results between academia and industry and to promote further progress in the area of  networking and services. We also hope that Rome, Italy provided a pleasant environment during the conference and everyone saved some time to enjoy the historic beauty of the city.

During the last twenty five years the fields of computer networks and data communications advanced rapidly in diverse parts of communications and computer industry, covering a wide spectrum that encompass local area networks, wireless networks, satellite communications, high-speed data transfer networks, etc. Two decades ago, few people had access to a network. Nowadays, computer communication has become an essential part of our infrastructure. Almost, every business enterprise, large or small, schools, at all grade levels from elementary to postgraduate , federal, state, and local-government offices, and even the entire industry, is using computer networks in order to provide the users with instantaneous access to information located in all places around the world. Today, the Internet has grown into a production communication system that reaches millions of people in all countries of the world. Doubtlessly, data communications and networking represent the fastest growing technologies nowadays. This book gives a broad view of the basic principles in data communications and networking. The authorÕs intention was to present the fundamentals of computer networks organization and data transfer principles rather than enter into more superficial discussions of modern networks design. The material is divided into seven parts, with a total of 31 chapters, 11 appendices, a list of frequently used acronyms, glossary of technical terms, and an extensive index. The book covers the following subjects: Part I-Overview of Data Communications and Networking (chapters 1 and 2) is just an introduction. Chapter 1 (Introduction, pp. 3-25) addresses four issues: data communications, networks, the Internet, and protocols and standards. Chapter 2 (Network Models, pp. 27-44) concentrates on a general idea of the layers of network and discusses the function of each. Part II-Physical Layer (chapters 3 to 9) deals with the physical layer of the Internet model. Chapter 3 (Signals, pp. 49-84) discusses the advantages and disadvantages of digital transmission over analog transmission.

It is widely recognized that the Internet transport layer has become ossified, where further evolution has become hard or even impossible. This is a direct consequence of the ubiquitous deployment of middleboxes that hamper the deployment of new transports, aggravated further by the limited flexibility of the application programming interface (API) typically presented to applications. To tackle this problem, a wide range of solutions have been proposed in the literature, each aiming to address a particular aspect. Yet, no single proposal has emerged that is able to enable evolution of the transport layer. In this paper, after an overview of the main issues and reasons for transportlayer ossification, we survey proposed solutions and discuss their potential and limitations. The survey is divided into five parts, each covering a set of point solutions for a different facet of the problem space: 1) designing middlebox-proof transports; 2) signaling for facilitating middlebox traversal; 3) enhancing the API between the applications and the transport layer; 4) discovering and exploiting end-to-end capabilities; and 5) enabling user-space protocol stacks. Based on this analysis, we then identify further development needs toward an overall solution. We argue that the development of a comprehensive transport layer framework, able to facilitate the integration and cooperation of specialized solutions in an application-independent and flexible way, is a necessary step toward making the Internet transport architecture truly evolvable. To this end, we identify the requirements for such a framework and provide insights for its development.
