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.

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
Special Features: · Focuses on the topic of designing and implementing computer network information transfer protocols. While we are all becoming familiar with the Internet, which uses the Transfer Control Protocol/Internet Protocol (TCP/IP), many computer networking solutions have been and will continue to be based on other perhaps proprietary, secure protocols About The Book: This book focuses on the design and implementation of these computer network information transfer protocols. Using the Internet as a running case study throughout the book, the authors introduce a formal notation for writing network protocols and organize their discussion around protocol functions

Book Description
Take an in-depth tour of core Internet protocols and learn how they work together to move data packets from one network to another. With this updated edition, you’ll dive into the aspects of each protocol, including operation basics and security risks, and learn the function of network hardware such as switches and routers. New chapters examine the transmission control protocol (TCP) and user datagram protocol in detail. Ideal for beginning network engineers, each chapter in this book includes a set of review questions, as well as practical, hands-on lab exercises. You’ll explore topics including: Basic network architecture: how protocols and functions fit together The structure and operation of the Ethernet protocol TCP/IP protocol fields, operations, and addressing used for networks The address resolution process in a typical IPv4 network Switches, access points, routers, and components that process packets TCP details, including packet content and client-server packet flow How the Internet Control Message Protocol provides error messages during network operations How network mask (subnetting) helps determine the network The operation, structure, and common uses of the user datagram protocol

Book Description
This thesis is on the subject of network protocol design. It takes a collection of known, practical problems that we face on the Internet—namely, abuses of the network—and considers these problems in light of both existing practical countermeasures and abstract analysis. Protocol design features and techniques with Machiavellian robustness are then proposed to address these problems, to the extent that such a remedy is possible. A protocol called ‘Invite’ is then designed from scratch using these new techniques. The Invite protocol thus serves as a practical example of design for Machiavellian robustness, but its duty as a protocol is to convey that robustness to some other protocol, so it is then applied to email (and its well-known abuses such as spamming and mailbombing). In that context, its effectiveness is analysed and compared with other approaches, both proposed and currently practised. Lastly, the broader implications of Machiavellian robustness are considered, suggesting possible avenues of future research.

Book Description
IPv6 was introduced in 1994 and has been in development at the IETF for over 10 years. It has now reached the deployment stage. KAME, the de-facto open-source reference implementation of the IPv6 standards, played a significant role in the acceptance and the adoption of the IPv6 technology. The adoption of KAME by key companies in a wide spectrum of commercial products is a testimonial to the success of the KAME project, which concluded not long ago. This book is the first and the only one of its kind, which reveals all of the details of the KAME IPv6 protocol stack, explaining exactly what every line of code does and why it was designed that way. Through the dissection of both the code and its design, the authors illustrate how IPv6 and its related protocols have been interpreted and implemented from the specifications. This reference will demystify those ambiguous areas in the standards, which are open to interpretation and problematic in deployment, and presents solutions offered by KAME in dealing with these implementation challenges. Covering a snapshot version of KAME dated April 2003 based on FreeBSD 4.8 Extensive line-by-line code listings with meticulous explanation of their rationale and use for the KAME snapshot implementation, which is generally applicable to most recent versions of the KAME IPv6 stack including those in recent releases of BSD variants Numerous diagrams and illustrations help in visualizing the implementation In-depth discussion of the standards provides intrinsic understanding of the specifications
