Tomo Ceferin (2011) Adaptable Ethernet Bridge. MSc thesis.
We prepared an overview of elements that comprise computer networks built using Ethernet protocol. We followed that with an overview of some frequently used network protocols. Our focus was on protocols daily encountered by regular users – mostly not knowingly. We then present Ethernet bridges and functions that form the basis of DSLAM bridge family. These bridges are separated from ordinary bridges by larger number of functions. They are used as access nodes, occupying the border between service providers and home and business users. We compared three bridge implementations on the basis of the following: • changes – ease of modification and maintenance; PROBLEM DISCOVERY – EASE OF IMPLEMENTATION AND CONFIGURATION PROBLEM DISCOVERY; duplication – same functions implemented multiple times, possibly even in different ways; SPEED – SPEED OF OPERATION; management – ease of management. Based on comparison we prepared a list of properties that would make maintenance simpler. We prepared a concept of improved architecture of modular bridge. We provide a mapping of the abstract concept to Linux kernel and an actual implementation for Linux kernel.
