Introduction
In today's mobile world inter-machine communication has become the key to information exchange - be it file transfers, chats or web surfing. Until now if you wanted to work in an ad-hoc network with a few peers you had to set most (if not all) information by hand. Then you exchanged information for the services you wanted to use. So at best networking was an annoyance, at worst it was a show stopper. Zero Configuration Networking aims to solve that problem by defining a set of protocols that can be used to assign IP addresses automatically, resolve names and discover services. This seminar paper describes several candidates to accomplish these tasks and gives reasons for a specific set of protocols, namely IPv4 Local-Link Addressing, Multicast DNS and DNS-based Service Discovery.Seminar Ubiquitos Computing
I participated in the seminar Ubiquitos Computing with this topic and compared the ZeroConf protocol suite to a few different approaches and showed how it scales from small ad-hoc networks to large corporate and enterprise networks. Below in the download section you find the slides and the accompanying paper of my talk.Informatiktage 2006
I was invited to the Informatiktage 2006 held by the Gesellschaft für Informatik (GI) to the infrastructure workshop. Below you find the short paper describing a basic scenario for ZeroConf networking to get an overview and the slides for a 10 min introductory talk. The paper appeared in the series "Lecture Notes in Informatics (LNI) - Seminars", Volume S-3, "Informatiktage 2006, Fachwissenschaftlicher Informatik-Kongress", p. 143-146.Further Information
