Meta-transport library user`s guide

Developing new transport protocols or protocol algorithms suffer from the complexity of the environment in which they are intended to run. Modeling techniques attempt to relieve this by simulating the environment. Our approach to promoting rapid prototyping of protocols and protocol algorithms is to provide a pre-built infrastructure that is common to all transport protocols, so that the focus is placed on the protocol-specific aspects. The Meta-Transport Library is a library of base classes that implement or abstract out the mundane functions of a protocol; new protocol implementations are derived from the base classes. The result is a fully viable transport protocol implementation, with emphasis on modularity. The collection of base classes form a {open_quotes}class-chest{close_quotes} of tools from which protocols can be developed and studied with as little change to a normal mix environment as possible. In addition to supporting protocol designers, this approach has pedagogical uses

An Object-Oriented Implementation of the Xpress Transfer Protocol

Object-oriented design principles map well onto protocol implementations because protocols essentially manipulate two structures---packets and the states of the endpoints. In this paper we describe an implementation of the Xpress Transfer Protocol as a user-space daemon written in C++. The object-oriented model forces the programmer to properly place functionality and information ownership. The model facilitates porting to various platforms and greatly eases the task of building data delivery services
