Biography

Joao Taveira Araujo was a member of the Communications and Information Systems Group (CISG) at the Department of Electronic and Electrical Engineering, University College London (UCL), UK. He obtained his Ph.D. in Electronic and Electrical Engineering from UCL in December 2013. His research interests are in the areas of congestion control, traffic engineering, transport-aware networking, and passive measurement techniques.

PhD project description

Parallelism pervades the Internet, yet efficiently pooling this increasing path diversity has remained elusive. With no holistic solution for resource pooling, each layer of the Internet architecture attempts to balance traffic according to its own needs, potentially at the expense of others. From the edges, traffic is implicitly pooled over multiple paths by retrieving content from different sources. Within the network, traffic is explicitly balanced across multiple links through the use of traffic engineering. This work explores how the current architecture can be realigned to facilitate resource pooling at both network and transport layers, where tension between stakeholders is strongest.

The central theme of this thesis is that traffic engineering can be performed more efficiently, flexibly and robustly through the use of re-feedback. A cross-layer architecture is proposed for sharing the responsibility for resource pooling across both hosts and network.
