Open Access padlockePrints

The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

COTraSE: Connection Oriented Traceback in Switched Ethernet

Abstract

Layer 2 traceback is an important component of end-to-end packet traceback. Whilst IP traceback identifies the origin network, L2 traceback extends the process to provide a more fine-grained result. Other known proposals have exposed the difficulties of L2 traceback in switched ethernet. We build on our earlier work and improve in a number of dimensions. Memory requirements are decreased by maintaining `connection records' rather than logging all frames. Our switchport resolution algorithm provides error detection by correlating MAC-table values from two switches. Furthermore, our solution takes stock of potential transformations to packet data as this leaves the local network.
