Project: Detecting transparent network devices

Many network devices (e.g. bridges, routers, address translators, firewalls and caches) are designed to be transparent to end-users, e.g. so that the devices can be added and removed without having to change end-user configurations. However, when these devices fail, end-users are often mystified that their network service is unavailable because of a device that they were never aware of. The goal of this thesis is to develop software that can discover which network elements an end-user depends upon in order to access network services. By identifying these devices, the end-user will be able to better localise faults, and will be able to determine which notifications from service providers about device outages affect their service. It will involve programming, and understanding of network protocols. Previous work includes the "macof" tool for detecting transparent bridges that use the Spanning Tree Protocol and STUN (RFC 3489) for detecting address translators.
