Research summary

Miguel Rio's research centres on Internet protocols and network algorithms. He is currently involved in several research threads:

P2P Real-time delivery - In the PeerLive project we are designing a system that will deliver live data (video, audio, etc) using the P2P paradigm. We address s several research issues: quick peer finding, QoS optimization and incentives for cooperation. We published in INFOCOM 2009 a novel mechanism for P2P incentives that solves many of the existing problems. Paper here .
Routing Resilience and Quality of Service - Are are presenting in Hotnets a very cool paper that implements routing resilience using packet re-cycling. We have also done lots of work on improving quality of service routing.
Internet Topologies and Generation Models - We have produced several publications that analyze Internet topologies and their dynamics. We have developed FETA framework to allow other researchers to evaluated their own models (paper in INFOCOM's NetSciCom here . This year we have published an interesting paper in Transactions on Networkingn that achieves novel conclusions on Internet topology evolution.
Network Monitoring and Measurement - In the MASTS project we built one of the world largest databases of packet traces from real traffic. We are now analyzing this data and provide solutions to several networking problems. One of such example is flow inversion (how to deduce which flows are in a network from limited packet sampling). We are expanding this research area considerably.
Congestion Control and Congestion Exposure - We are trying to re-engineering the way congestion is dealt with in the Internet (recent paper in ReArch here). Recently we developed an algorithm to adequetely improve congestion response that uses just one bit.

Biography

Dr Miguel Rio is a Senior Lecturer at the Department of Electronic and Electrical Engineering. He did his undergraduate studies in University of Minho, Portugal and his PhD in the University of Kent, United Kingdom. His dissertation was in Quality of Service Multicast, a topic he still pursues. He was a post-doctoral at UCL where he research programmable networks and congestion control. Since then he has helped to coordinate several projects both at the UK and EU level. HE has made substantial contributions to network measurement, network routing and peer-to-peer networks.
