[Nets-seminars] Seminar today UCL Electronic Engineering

[Richard G. Clegg]

Today's seminar is at 16:00 in GS/102, 66-72 Gower Street.  I look 
forward to seeing you all there.  The speaker is Marinos Charalambides.

*Title:* Energy-Aware Adaptive Network Resource Management

*Abstract:*
Resource over-provisioning is common practice in network 
infrastructures. Coupled with energy unaware networking protocols, this 
can lead to periods of resource under-utilisation and constant energy 
consumption irrespective of the traffic load conditions. Driven by the 
rising cost of energy -- and therefore OPEX -- and increasing 
environmental consciousness, research in power saving techniques has 
recently received significant attention. Unlike the majority of previous 
work in the area, which has focused on centralised offline approaches, 
we propose an online approach by which the capacity of the network can 
be adapted in a decentralised fashion. Based on the modular 
architectures of modern IP routers, adaptation is achieved by 
configuring individual line cards to enter sleep mode. Re-configuration 
is performed periodically by intelligent ingress nodes that coordinate 
their actions in order to control the traffic distribution in the 
network, according to the actual demand. The approach is evaluated using 
real network topologies and traffic traces under different load conditions.

*Bio:*
Marinos Charalambides is a Research Fellow at the Department of 
Electronic & Electrical Engineering, UCL. He received a BEng in 
Electronic and Electrical Engineering, an MSc in Communications Networks 
and Software, and a PhD in Policy-based Management, all from the 
University of Surrey, UK, in 2001, 2002 and 2009, respectively. His 
research interests focus on network and service management.
