Designing Energy-Efficient Wireless Access Networks: LTE and LTE-Advanced
IEEE Internet Computing
By Margot Deruyck,Wout Joseph,Bart Lannoo,Didier Colle,Luc Martens
Issue Date:September 2013
As large energy consumers, base stations need energy-efficient wireless access networks. This article compares the design of Long-Term Evolution (LTE) networks to energy-efficient LTE-Advanced networks. LTE-Advanced introduces three new functionalities--ca...
Techno-economic Analysis of Software Defined Networking as Architecture for the Virtualization of a Mobile Network
2012 European Workshop on Software Defined Networking (EWSDN)
By Bram Naudts,Mario Kind,Fritz-Joachim Westphal,Sofie Verbrugge,Didier Colle,Mario Pickavet
Issue Date:October 2012
Worldwide mobile network operators have to spend billions to upgrade their own network to the latest standards for wireless communication of high-speed data for mobile phones (e.g. Long Term Evolution, LTE). This is in contrast with the decline in average ...
Emulation of GMPLS-controlled Ethernet Label Switching
Testbeds and Research Infrastructures for the Development of Networks & Communities, International Conference on
By Wouter Tavernier, Dimitri Papadimitriou, Didier Colle, Mario Pickavet, Piet Demeester
Issue Date:April 2009
Last decades bridged Ethernet has been the de facto standard layer 2 technology for LAN environments. This is mainly because it is easy to deploy, it has low cost and is relatively robust. These attractive properties together with highly increasing PHY spe...
Controlling LSPs in an ORION Network
Broadband Networks, International Conference on
By Jan Cheyns, Erik Van Breusegem, Didier Colle, Mario Pickavet, Piet Demeester, Davy De Winter
Issue Date:October 2004
New networking paradigms try to combine packet switching and circuit switching, keeping the best of both worlds and getting rid of the drawbacks. One promising technology is Overspill Routing in Optical Networks (ORION). In this paper we develop a control ...
Automatic configuration of routing control platforms in OpenFlow networks
Found in: Proceedings of the ACM SIGCOMM 2013 conference on SIGCOMM (SIGCOMM '13)
By Didier Colle, Dimitri Staessens, Mario Pickavet, Piet Demeester, Sachin Sharma
Issue Date:August 2013
RouteFlow provides a way to run routing control platforms (e.g. Quagga) in OpenFlow networks. One of the issues of RouteFlow is that an administrator needs to devote a lot of time (typically 7 hours for 28 switches) in manual configurations. We propose and...
OSPF failure reconvergence through SRG inference and prediction of link state advertisements
Found in: Proceedings of the ACM SIGCOMM 2011 conference on SIGCOMM (SIGCOMM '11)
By Bart Puype, Didier Colle, Dimitri Papadimitriou, Goutam Das, Mario Pickavet, Piet Demeester
Issue Date:August 2011
We demonstrate machine learning augmented Open Shortest Path First (OSPF) routing which infers Shared Risk Groups (SRG) from link failure history. For an initial link failure matching an SRG, it predicts subsequent link state advertisements corresponding w...
