Available in PDF, EPUB and Kindle. Book excerpt: The main purpose of routing and flow control in a communication network is, roughly speaking, to keep delay per message within an acceptable level while minimizing the amount of offered traffic that is rejected by the network due to its inability to handle it. These two objectives are clearly contradictory so a good routing and flow control scheme must strike a balance between the two. It should also take into account a number of other issues such as fairness for all users, the possibility that the network topology can be altered due to unexpected link or node failures, and the fact that the statistics of offered traffic change with time. In these notes we consider some aspects of routing and flow control for long-haul wire data networks in which the communication resource is scarce (as opposed to local networks such as Ethernet where it is not), and where there are no issues of contention resolution due to random access of a broadcast medium (as in some satellite, local, and packet radio networks). We place primary emphasis on optimal procedures since these offer a more sound philosophical basis than heuristic schemes and also provide a yardstick for measuring the effectiveness of other methods.

This book was released on 2011-08-26 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before the appearance of broadband links and wireless systems, networks have been used to connect people in new ways. Now, the modern world is connected through large-scale, computational networked systems such as the Internet. Because of the ever-advancing technology of networking, efficient algorithms have become increasingly necessary to solve some of the problems developing in this area. "Mathematical Aspects of Network Routing Optimization" focuses on computational issues arising from the process of optimizing network routes, such as quality of the resulting links and their reliability. Algorithms are a cornerstone for the understanding of the protocols underlying multicast routing. The main objective in the text is to derive efficient algorithms, with or without guarantee of approximation. Notes have been provided for basic topics such as graph theory and linear programming to assist those who are not fully acquainted with the mathematical topics presented throughout the book. "Mathematical Aspects of Network Routing Optimization" provides a thorough introduction to the subject of algorithms for network routing, and focuses especially on multicast and wireless ad hoc systems. This book is designed for graduate students, researchers, and professionals interested in understanding the algorithmic and mathematical ideas behind routing in computer networks. It is suitable for advanced undergraduate students, graduate students, and researchers in the area of network algorithms.
Download or read book Flow Control and Routing Algorithms for Data Networks written by R. G. Gallager and published by . This book was released on 1980 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: We consider flow control algorithms consisting of two parts: quasi-static flow control and dynamic flow control. The quasi-static part uses short term average information on network utilization to allocate maximum data rates and to determine routes for each user. The rates are allocated to achieve an optimal trade-off between assigned priority cost functions for each user and the cost of congestion in the network. This optimization can be done by a distributed algorithm and is essentially no more complicated than optimizing routing alone. The dynamic flow control has the function of admitting or rejecting individual units of traffic into the network so as to enforce the maximum allocated rates and to prevent congestion by smoothing out the fluctuations in buffer occupancy.

Download or read book Flow Control and Routing in an Integrated Voice and Data Communication Network written by Oliver Chukwudi Ibe and published by . This book was released on 1981 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper considers a model of an integrated voice and data network. The model, which lends itself to analytic and algorithmic solution, is formulated as a convex optimization problem. The objective function comprises two types of functions: the congestion cost functions and the rate limitation functions. The congestion cost functions act to limit the average traffic entering into the network to values that would not cause network congestion. The rate limitation functions ensure that all conversations are fairly treated. The model can be generalized to solve problems of networks which handle n types of traffic that have different levels of delay sensitivity, where n> or = 2. A joint flow control and routing algorithm is constructed which uses short term average information on the network utilization to set the voice packet lengths and data input rates, and to determine the routes for each conversation. The voice packet lengths and data input rates are set in such a way as to achieve an optimal tradeoff between each user's satisfaction and the cost of network congestion. Additional protocols are specified for dealing with such issues as congestion avoidance and control, and for implementing flow control on a more dynamic basis than the quasi-static joint flow control and routing algorithm can handle.

Available in PDF, EPUB and Kindle. Book excerpt: As the number of processor cores and IP blocks integrated on a single chip is steadily growing, a systematic approach to design the communication infrastructure becomes necessary. Different variants of packed switched on-chip networks have been proposed by several groups during the past two years. This book summarizes the state of the art of these efforts and discusses the major issues from the physical integration to architecture to operating systems and application interfaces. It also provides a guideline and vision about the direction this field is moving to. Moreover, the book outlines the consequences of adopting design platforms based on packet switched network. The consequences may in fact be far reaching because many of the topics of distributed systems, distributed real-time systems, fault tolerant systems, parallel computer architecture, parallel programming as well as traditional system-on-chip issues will appear relevant but within the constraints of a single chip VLSI implementation.

Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this research were the investigation of certain issues on routing, flow control, and the relationship between the two. More specifically, the following research tasks were carried out: (1) It was shown that while deterministic routing may seem to perform better under stable traffic conditions, the adaptive strategy out-performs the deterministic one for networks spanning several time zones; (2) Approximation models were determined for determining response time on a virtual circuit under the real network condition that arriving packets encountering a full window wait in buffers instead of being discarded, as in the case of earlier models; (3) A detailed simulation model was developed to verify the approximate analytic model and to perform certain experiments; (4) A strategy for determining optimal window size was developed based on the minimum-cut of a multi-commodity problem. Originator supplied keywords: Adaptive routing; Deterministic routing; Flow control; Window-type flow control; Coxian distribution; Virtual circuits; Window size; Routing table; Update epoch; Multi-commodity problem; Minimum-cut.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is a compendium of papers presented during the NATO Workshop which took place in Capri, Italy, October 12-18, 1986 on the general subject of "Flow Control of Congested Networks: The Case of Data Processing and Transportation", and of which we acted as co-chairmen. The focus of the workshop was on flow control methodologies, as applied to preventing or reducing congestion on: (1) data communication networks; (2) urban transportation networks; and (3) air traffic control systems. The goals of the workshop included: review of the state-of-the-art of flow control methodologies, in general, and in each of the three application areas; identification of similarities and differences in the objective functions, modeling approaches and mathematics used in the three areas; examination of opportunities for "technology transfers" and for future interactions among researchers in the three areaso These goals were pursued through individual presentations of papers on current research by workshop participants and, in the cases of the second and third goals, through a number of open-ended discussion and-review sessions which were interspersed throughout the workshop's programmeD The full texts or extended summaries of all but a few of the papers given at the workshop are included in this volume.
