Three approaches can be applied to determine the performance of parallel and distributed computer systems: measurement, simulation, and mathematical methods. This book introduces various network architectures for parallel and distributed systems as well as for systems-on-chips, and presents a strategy for developing a generator for automatic model derivation. It will appeal to researchers and students in network architecture design and performance analysis.
This rigourous and self-contained book describes mathematical and, in particular, stochastic methods to assess the performance of networked systems. It consists of three parts. The first part is a review on probability theory. Part two covers the classical theory of stochastic processes (Poisson, renewal, Markov and queuing theory), which are considered to be the basic building blocks for performance evaluation studies. Part three focuses on the relatively new field of the physics of networks. This part deals with the recently obtained insights that many very different large complex networks - such as the Internet, World Wide Web, proteins, utility infrastructures, social networks - evolve and behave according to more general common scaling laws. This understanding is useful when assessing the end-to-end quality of communications services, for example, in Internet telephony, real-time video and interacting games. Containing problems and solutions, this book is ideal for graduate students taking courses in performance analysis.
Traditionally, networking has had little or no basis in analysis or architectural development, with designers relying on technologies they are most familiar with or being influenced by vendors or consultants. However, the landscape of networking has changed so that network services have now become one of the most important factors to the success of many third generation networks. It has become an important feature of the designer's job to define the problems that exist in his network, choose and analyze several optimization parameters during the analysis process, and then prioritize and evaluate these parameters in the architecture and design of the system. Network Analysis, Architecture, and Design, Third Edition, uses a systems methodology approach to teaching these concepts, which views the network (and the environment it impacts) as part of the larger system, looking at interactions and dependencies between the network and its users, applications, and devices. This approach matches the new business climate where customers drive the development of new services and the book discusses how networks can be architected and designed to provide many different types of services to customers. With a number of examples, analogies, instructor tips, and exercises, this book works through the processes of analysis, architecture, and design step by step, giving designers a solid resource for making good design decisions. With examples, guidelines, and general principles McCabe illuminates how a network begins as a concept, is built with addressing protocol, routing, and management, and harmonizes with the interconnected technology around it. Other topics covered in the book are learning to recognize problems in initial design, analyzing optimization parameters, and then prioritizing these parameters and incorporating them into the architecture and design of the system. This is an essential book for any professional that will be designing or working with a network on a routine basis. Substantially updated design content includes ad hoc networks, GMPLS, IPv6, and mobile networking Written by an expert in the field that has designed several large-scale networks for government agencies, universities, and corporations Incorporates real-life ideas and experiences of many expert designers along with case studies and end-of-chapter exercises
This thesis describes a method for static performance analysis for obtaining upper bounds on delay and buffering requirements in a SoC architecture. The method is based on network calculus theory known as LR servers. This network calculus is extended and applied to make it support SoC performance analysis. Performance requirements of subsystems are elegantly captured as traffic flows and associated latency constraints. The SoC infrastructure is modeled as a set of LR servers to validate that the worst-case delays in handling the traffic flows meet the latency constraints. The power of the performance analysis method is demonstrated by analyzing several schedule and interconnect variants for a multi-channel DVB-T set-top box case study. The influence of the frequency of the memory system and the pipeline degree of the traffic streams is shown. Furthermore, the influence of the packet size on the buffering requirements is analyzed. Key architecture choices, such as schedule or interconnect variant, can be varied easily to support exploration of architecture options.
The book is written at postgraduate level and comprises N chapters dealing with the following subjects: internetworking; network fundamentals; routing; computer networks; Internet Protocol addressing; network analysis; network architecture; network-requirement analysis; network flow analysis; network performance evaluation; network simulation models; statistical models; performance analysis; discrete random variables; continuous random variables; random variable generation; queuing theory; single-server-queues; and multiserver queues.
