Book Description
There are two groups of researchers who are interested in designing network protocols and who cannot (yet) effectively communicate with one another c- cerning these protocols. The first is the group of protocol verifiers, and the second is the group of protocol implementors. The main reason for the lack of effective communication between these two groups is that these groups use languages with quite different semantics to specify network protocols. On one hand, the protocol verifiers use specification languages whose semantics are abstract, coarse-grained, and with large atom- ity. Clearly, protocol specifications that are developed based on such semantics are easier to prove correct. On the other hand, the protocol implementors use specification languages whose semantics are concrete, fine-grained, and with small atomicity. Protocol specifications that are developed based on such - mantics are easier to implement using system programming languages such as C, C++, and Java. To help in closing this communication gap between the group of protocol verifiers and the group of protocol implementors, we present in this monograph a protocol specification language called the Timed Abstract Protocol (or TAP, for short) notation. This notation is greatly influenced by the Abstract Protocol Notation in the textbook Elements of Network Protocol Design, written by the second author, Mohamed G. Gouda. The TAP notation has two types of sem- tics: an abstract semantics that appeals to the protocol verifiers and a concrete semantics thatappeals to the protocol implementors group.

Book Description
Maintaining a balance between a theoretical and practical approach to this important subject, Elements of Compiler Design serves as an introduction to compiler writing for undergraduate students. From a theoretical viewpoint, it introduces rudimental models, such as automata and grammars, that underlie compilation and its essential phases. Based on these models, the author details the concepts, methods, and techniques employed in compiler design in a clear and easy-to-follow way. From a practical point of view, the book describes how compilation techniques are implemented. In fact, throughout the text, a case study illustrates the design of a new programming language and the construction of its compiler. While discussing various compilation techniques, the author demonstrates their implementation through this case study. In addition, the book presents many detailed examples and computer programs to emphasize the applications of the compiler algorithms. After studying this self-contained textbook, students should understand the compilation process, be able to write a simple real compiler, and easily follow advanced books on the subject.

Book Description
This book constitutes the refereed proceedings of the 7th International Symposium on Self-Stabilizing Systems, SSS 2005, held in Barcelona, Spain, in October 2005. The 15 revised full papers presented were carefully reviewed and selected from 33 submissions. The papers address classical topics of self-stabilization, prevailing extensions to the field, such as snap-stabilization, code stabilization, self-stabilization with either dynamic, faulty or Byzantine components, or deal with applications of self-stabilization, either related to operating systems, security, or mobile and ad hoc networks.

Book Description
A number of issues combine to make network protocol development significantly more difficult than other areas of computer programming: problems with time, concurrency, and failures; interactions between the network protocol and its environment; and obstacles in developing the protocol over time. In order to address these issues, we introduce the Timed Abstract Protocol notation and the Austin Protocol Compiler. The Timed Abstract Protocol, or TAP, notation is a domain-specific formal language for describing asynchronous message-passing network protocols, with two execution models: an abstract execution model and a concrete execution model. The abstract execution model is suited for protocol design, comprehension, and correctness verification. The concrete execution model is suited for protocol implementation. We show that the two models are equivalent: that a protocol interpreted under the concrete model preserves the intended behavior of the protocol interpreted under the abstract model. The Austin Protocol Compiler, or APC, is a system that transforms a protocol given in the Timed Abstract Protocol notation into executable C code and provides a runtime environment for the protocol. In order to demonstrate the effectiveness of the TAP notation and APC, we present implementations of a secure encryption key exchange protocol, a failure discovery protocol, and a Domain Name System server. While discussing the latter, we examine the performance of the APC implementation and show that it is comparable to two other DNS servers. The combination of the Timed Abstract Protocol notation and the Austin Protocol Compiler addresses the issues of network protocol development by allowing precise and verifiable descriptions of protocols which can be made executable easily, in order both to gain experimental experience and to provide reference implementations.
