The Cognitive Packet Network

Abstract:  The Cognitive Packet Network (CPN) is a bio-inspired packet network routing method, which is adaptive, distributed and robust, and which has both been patented and implemented. We will describe CPN and detail its reinforcement learning based quality of service routing approach which uses measurements and a Random Neural Network as the adaptive critic and decision engine. We will outline the motivation for this technique, and detail its principles and implementation. Experiments on a large scale laboratory test-bed will be described and presented to illustrate the method. Extensions of CPN to the defence of a network against attacks and to energy-aware routing will also be discussed.



Brief Bio:  Erol Gelenbe was born in Turkey and received his PhD in the USA. During 1973-93, he was first a Research Director at INRIA, he founded the performance modelling and evaluation groups in France,  influenced the creation of research groups throughout Europe, and held professorships at the Universities of Liege (Belgium), Paris-Sud (Orsay) and Paris V.  He has invented new mathematical models, such as the Random Neural Networks and G-Networks, and contributed to practical developments such as the SYCOMORE Voice-packet switch, the XANTHOS fibre-optics local area network, the QNAP and FLEXSIM simulation/modelling packages, and the CPN machine learning based packet routing algorithm. He has held chaired professorships at New Jersey Institute of Technology, Duke University, University of Central Florida, and is currently the “Dennis Gabor Professor” at Imperial College. He graduated over 74 PhDs, including 17 women. 47 of his former PhD students work in Europe. Elected Fellow of ACM and IEEE, his awards include Chevalier de la Legion d’honneur, Officier du Merite, Commendatore al Merito (IT), Grand Prix France Telecom (French Academy of Sciences), ACM SIGMETRICS Life-Time Achievement Award, Denis Gabor Award (Hungarian Academy of Sciences), Oliver Lodge Medal (IET, UK), and three “doctorates honoris causa”. He was elected Fellow of the National Academy of Technologies (FR), the Royal Academy of Belgium, and the Science Academies of Hungary, Poland and Turkey.
