This book was released on 2012-12-06 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing performance guarantees is one of the most important issues for future telecommunication networks. This book describes theoretical developments in performance guarantees for telecommunication networks from the last decade. Written for the benefit of graduate students and scientists interested in telecommunications-network performance this book consists of two parts. The first introduces the recently-developed filtering theory for providing deterministic (hard) guarantees, such as bounded delay and queue length. The filtering theory is developed under the min-plus algebra, where one replaces the usual addition with the min operator and the usual multiplication with the addition operator. As in the classical linear system theory, the filtering theory treats an arrival process (or a departure process ) as a signal and a network element as a system. Network elements, including traffic regulators and servers, can be modelled as linear filters under the min-plus algebra, and they can be joined by concatenation, "filter bank summation", and feedback to form a composite network element. The problem of providing deterministic guarantees is equivalent to finding the impulse response of composite network elements. This section contains material on: - (s, r)-calculus - Filtering theory for deterministic traffic regulation, service guarantees and networks with variable-length packets - Traffic specification - Networks with multiple inputs and outputs - Constrained traffic regulation The second part of the book addresses stochastic (soft) guarantees, focusing mainly on tail distributions of queue lengths and packet loss probabilities and contains material on: - (s(q), r(q))-calculus and q-envelope rates - The large deviation principle - The theory of effective bandwidth The mathematical theory for stochastic guarantees is the theory of effective bandwidth. Based on the large deviation principle, the theory of effective bandwidth provides approximations for the bandwidths required to meet stochastic guarantees for both short-range dependent inputs and long-range dependent inputs.

Available in PDF, EPUB and Kindle. Book excerpt: Seemingly, the era of ubiquitous connectivity has arrived, with smart phones, tablets, and small computing devices bringing internet straight to our fingertips - or has it? Two thirds of the world still does not have access to the internet, and a lack of realistic communication guarantees for multi-agent robotic networks are standing in the way of taking these systems from research labs into the real world. In this thesis we consider the problem of satisfying communication demands in a multi-agent system where several robots cooperate on a task and a fixed subset of the agents act as mobile routers. Our goal is to position the team of robotic routers to provide communication coverage to the remaining client robots, while allowing clients maximum freedom to achieve their primary coordination task. We develop algorithms and performance guarantees for maintaining a desired communication quality over the entire heterogeneous team of controlled mobile routers and non-cooperative clients. In the first part of the thesis we consider the problem of router placement while explicitly accounting for client motion over a priori unknown trajectories. We formulate this problem as a novel optimization called the connected reachable k-connected center problem that extends the classical k-center problem. We propose an algorithm to compute a small representative set of clients where this set is of size (klog(n)/[epsilon])O (1), can be constructed in O(nk) time and updated in (klog(n)/[epsilon])O (1) time as clients move along their trajectories. Here k is the number of routers, n is the number of clients, and s is a user-defined acceptable error tolerance. Our router placement algorithm applied to this sparse set provides a configuration of router positions that is bounded by a multiplicative factor, (1 + [epsilon]) from optimal. Secondly, we incorporate a realistic communication model into our router placement optimization problem. We do this by developing a novel method of directional signal strength mapping that has sufficient richness of information to capture complex wireless phenomena such as fading and shadowing, and can be used to derive a simple optimization formulation that is based on quadratic link costs and is solved using our router placement algorithm. Using off-the-shelf hardware platforms we present aggregate results demonstrating that the resulting router placements satisfy communication demands across the network with 4X smaller standard deviation in performance and 3.4X faster convergence time than existing methods, and our solutions assume no environment map and unknown client positions. Finally, we derive distributed controllers for the special case where clients are static. We show that by the tuning of a control parameter our routers maintain a connected network using only local information. We support our theoretical claims with experimental results using AscTec hummingbird platforms as well as iRobot Create platforms of small 10 client and large 500 virtual client implementations.

Available in PDF, EPUB and Kindle. Book excerpt: It is always confusing, and perhaps inconvenient at times, using generic terms that will mean something to everyone but different things to different people. "High Performance" is one of those terms. High Performance can be viewed as synonymous to High Speed or Low Latency or a number of other characteristics. The interesting thing is that such ambiguity can sometimes be useful in a world where focus shifts quite easily from one issue to another as times and needs evolve. Many things have changed since the first HPN conference held in Aachen, Germany in 1987. The focus then was mainly on Media Access Control (MAC) protocols that allow users to share the high bandwidth of optical fiber. FDDI (Fiber Distributed Data Interface) was making its debut with its amazing 100 Mbps speed. ATM (Asynchronous Transfer Mode) and SONET (the Synchronous Optical Network) were beginning to capture our imagination. What could users possibly do with such "high performance"? Share it! After realizing that the real problems had gradually shifted away from the network media to the periphery of the network, focus also began to shift. Adapter design, protocol implementation, and communication systems architecture began to attract our interest. Networking -not Networks-became the hot issue.

Available in PDF, EPUB and Kindle. Book excerpt: This workshop was a continuation of the PCRCW ’94 workshop that focused on issues in parallel communication and routing in support of parallel processing. The workshop series provides a forum for researchers and designers to exchange ideas with respect to challenges and issues in supporting communication for high-performance parallel computing. Within the last few years we have seen the scope of interconnection network technology expand beyond traditional multiprocessor systems to include high-availability clusters and the emerging class of system area networks. New application domains are creating new requirements for interconnection network services, e.g., real-time video, on-line data mining, etc. The emergence of quality-of-service guarantees within these domains challenges existing approaches to interconnection network design. In the recent past we have seen the emphasis on low-latency software layers, the application of multicomputer interconnection technology to distributed shared-memory multiprocessors and LAN interconnects, and the shift toward the use of commodity clusters and standard components. There is a continuing evolution toward powerful and inexpensive network interfaces, and low-cost, high-speed routers and switches from commercial vendors. The goal is to address the above issues in the context of networks of workstations, multicomputers, distributed shared-memory multiprocessors, and traditional tightly-coupled multiprocessor interconnects. The PCRCW ’97 workshop presented 20 regular papers and two short papers covering a range of topics dealing with modern interconnection networks. It was hosted by the Georgia Institute of Technology and sponsored by the Atlanta Chapter of the IEEE Computer Society.
