The performance of most real-time streaming media applications is sensitive to transmission delays. This paper describes a distributed admissions control method to ensure the required sending rates for the real-time media streams. A utility function is first developed to model the satisfaction of delay-sensitive media streams. Then, the optimal admissions control on streams are formulated into a social optimum oriented network utility maximization (NUM) problem. A distributed admissions control method can be developed based on the dual decomposition of the primal problem. The construction of this distributed admissions control method follows the DiffServ approach.

As data and knowledge volumes keep increasing, and global means for information dissemination continues to diversify, new methods, modeling paradigms and structures are needed to efficiently support the mounting scalability requirements for the large variety of current and future data, information, and knowledge [1–3]. Grid computing, peer-to-peer technology, data and knowledge bases, distributed information retrieval technology, and networking technology should all converge to address the scalability concern. This special section compiles recent work on addressing scalability issues of distributed and peer-to-peer systems. Selected papers from the Second internationalconference on Scalable Information Systems (INFOSCALE 2007) were invited for extension and submission to this special section. Finally, five papers were included in this special section.

The Internet-of-Things represent a future trend of the Internet, in which massive numbers of networked objects are assumed to have the capability of sharing data collected through sensing activities. It is envisioned that such objects are not dedicated hardware modules embedded specific machines communicating via proprietary wired or wireless networks to dedicated software applications. On contrary, Internet-of-Things may have a more autonomic deployment, in which objects are autonomous and communicate via existing IP based networks. Due to its distributed nature, there is the need to rely on autonomic networking to improve the efficiency while reducing the operational costs of Internet-of-Things frameworks. This paper aims to provide a study about the best data plane to support Internet-of-Things, and an analysis about the best model to support its distributed autonomic behavior.

In this paper, we describe the networking and distributed systems challenges and opportunities that are present in adoption of information and computing technology (ICT) in the developing world, and illustrate connections between these challenges and current distributed systems and networking research programs. We suggest that this agenda form a core element of the ambitious program of network experimentation now commencing in the United States, European Union, and Japan.

Edge computing established paradigms are prone to implicate solely powerful server-like edge nodes, in static or semistatic topologies, of centrally-controlled edge networks. In this paper, leveraging upon recent technological advancements and trends, we introduce a novel networking paradigm employing resources provided by independent crowd peers, within a zone of local proximity, to establish collaborative networks for edge computing. We call this paradigm the Crowdsourced Edge. We detail the architecture and characteristics of this novel paradigm, highlighting its unique characteristics and specific challenges, while also positioning it vis-a-vis the existing edge computing concretisations. Finally, we demonstrate the Crowdsourced Edge functionality by presenting an ongoing use case regarding a video-enhanced object search.

Internet of things is a new technology which is heavily affecting different aspects of human life. The number of smart devices connecting to IoT and the amount of data gathered or produced by these devices are increasing. In order to organize, secure and analyse the IoT data, novel and creative ideas for IoT design and management are required. Software Defined networking is a new and promising paradigm. Its main idea is to decouple the control functions from physical devices and set them inside a logically centralized control layer. In this paper, a distributed approach is proposed for accelerating data management and balancing the load between IoT devices based on SDN principles. The proposed framework makes it possible to apply different management strategies in a distributed manner. Experimental results indicate that our scheme distributes tasks between devices equally and exhibits a reduction in the average turnaround time and the average waiting time and it will improve the processing performance.

The development situation of communication system of small satellites in formation in China and aboard is first introduced. With the development of small satellites at present and the needs of small satellites for space flying mission, the fundamental technologies of hardware structure supporting reconfigurable computing based on FPGA and the distributedcomputing technology are analyzed in this paper. The application of these two technologies in formation-flying pico-satellites communication is demonstrated, and it is verified through an experiment of distributed compressing images that the distribution technology can be implemented in such a reconfigurable hardware structure. The combination of these two technologies can make good use of software and hardware sources of pico-satellite. A design scheme of pico-satellite based on these two technologies is presented at last.

We present new techniques for compilation of arbitrarily nested loops with affine dependences for distributed-memory parallel architectures. Our framework is implemented as a source-level transformer that uses the polyhedral model, and generates parallel code with communication expressed with the Message Passing Interface (MPI) library. Compared to all previous approaches, ours is a significant advance either (1) with respect to the generality of input code handled, or (2) efficiency of communication code, or both. We provide experimental results on a cluster of multicores demonstrating its effectiveness. In some cases, code we generate outperforms manually parallelized codes, and in another case is within 25% of it. To the best of our knowledge, this is the first work reporting end-to-end fully automatic distributed-memory parallelization and code generation for input programs and transformation techniques as general as those we allow.

Currently, there are numbers of different architectural proposals for future internet that focus on content-centric networking as the alternative of the existing location-based networking. These architectures give more emphasis on the security part of their paradigms and pay little attention or ignore on issues of privacy in their architectural designs. In this paper we propose the Scalable and Privacy Preserving Routing Protocol in Named Data networking (SP-NDN) by utilizing the multiple Bloom filters in order to ameliorate users interest packet flow privacy and security during the transit. In contrast to existing schemes, we present a content-dependent key tree based on multicast key management protocol to integrate Bloom filter and multicast encryption that mitigates the leakage of the original users keywords and precluding unauthorized users (eavesdroppers) from guessing the key words. Our schemes guarantee the high security and privacy of users interest packet during the transmission and at the same time trying to minimize the possible increase number of false positives likely to happen when a content is queried.

The highly development of Mobile Cloud computing (MCC) expose many limitations and critical challenges to traditional host-centric IP networks. This paper presents the design of Software-Defined Service-Centric Networks (SD-SCN) to facilitate the networking requirement of MCC. SD-SCN provides a service-level abstraction of communication endhosts to enable name-based routing and explores recent emerging Software-Defined networking (SDN) concept to enable service-oriented customizable network management. We illustrate some significant benefits taken by SD-SCN to MCC.
