This book concerns peer-to-peer applications and mechanisms operating on the Internet, particularly those that are not fully automated and involve significant human interaction. So, the realm of interest is the intersection of distributed systems and online social networking. Generally, simple models are described to clarify the ideas. Beginning with short overviews of caching, graph theory and game theory, we cover the basic ideas of structured and unstructured search. We then describe a simple framework for reputations and for iterated referrals and consensus. This framework is applied to a problem of sybil identity management. The fundamental result for iterated Byzantine consensus for a relatively important issue is also given. Finally, a straight-forward epidemic model is used to describe the propagation of malware on-line and for BitTorrent-style file-sharing.This short book can be used as a preliminary orientation to this subject matter. References are given for the interested student to papers with good survey and tutorial content and to those with more advanced treatments of specific topics. For an instructor, this book is suitable for a one-semester seminar course. Alternatively, it could be the framework for a semester's worth of lectures where the instructor would supplement each chapter with additional lectures on related or more advanced subject matter. A basic background is required in the areas of computer networking, probability theory, stochastic processes, and queueing.Table of Contents: Networking overview / Graphs / Games / Search in structured networks / Search in unstructured networks / Transactions, reputations, and referrals / False Referrals / Peer-to-peer file sharing / Consensus in dynamical belief systems / Byzantine consensus / Epidemics

ATM Network Performance describes a unified approach to ATM network management. The focus is on satisfying quality-of-service requirements for individual B-ISDN connections. For an ATM network of output-buffer switches, the author describes how the basic network resources (switch buffer memory and link transmission bandwidth) should be allocated to achieve the required quality-of-service connections. The performance of proposed bandwidth scheduling policies is evaluated. Both single node and end-to-end performance results are given. In particular, these results are applied to resource provisioning problems for prerecorded (stored) video and video teleconferencing. The flow control problem for available bit rate traffic is also described. This book is intended for a one-term course in performance of Broadband Integrated-Services Digital Networks (B-ISDNs) based on a type of packet-switched communication network called Asynchronous Transfer Mode (ATM). The level of presentation is at the first year of graduate studies and for professionals working in the field, but it may be accessible to senior undergraduates as well. Some familiarity with ATM standards is assumed as such standards are only briefly outlined. All of the required background in discrete-time queueing theory is supplied. Exercises are given at the end of chapters. Solutions and/or hints to selected exercises are given in an Appendix.

ATM Network Performance, Second Edition, describes approaches to computer and communication network management at the ATM layer of the protocol hierarchy. New material on round-robin scheduling, jitter control, QoS paradigms as well as special treatment of fluid modeling and variable bit rate channel capacity.
