DESCRIPTION:The transmission of digital TV over an IP infrastructure – I
 PTV – is one of the fastest growing television services in the world. Th
 e number of IPTV users escalated from 2 million in 2005 to 14 million in 2
 007. The strict requirements imposed to the network\, namely in terms of b
 andwidth and QoS guarantees\, will certainly have a tremendous impact in t
 he IP network. This fact\, together with the emergence of High Definition 
 TV and the fibre to the home trend in access networks\, is moving the bott
 leneck to the core. In consequence\, access and transport networks will ne
 ed some reengineering for multicast and QoS. \n\nIn my PhD programme we ai
 m to design a GMPLS system for provisioning optical core and access networ
 ks for Multicast TV. In this talk I will firstly present the motivation an
 d the planning for this research work. As part of the plan\, we propose to
  create a novel IPTV traffic model. This is work in progress\, but I will 
 present preliminary results. Finally\, I will also present a case study wh
 ere we used the first version of the GMPLS infrastructure that will be use
 d in our research work. This was used to evaluate a routing algorithm we h
 ave proposed to mitigate a power excursion problem that occurs in all opti
 cal networks. This work resulted in a paper that was recently accepted for
  presentation in the Optical Fibre Communication conference (OFC 2009).\n\
 nBio: I am a PhD student from the University of Cambridge. I have two supe
 rvisors\, Professor Ian White\, from the Department of Engineering\, and P
 rofessor Jon Crowcroft\, from the Computer Laboratory. Prior to this\, I g
 raduated in 2001 from the University of Aveiro\, Portugal\, in Electronics
  and Telecommunications Engineering\, and I also have an MSc in Telecommun
 ications from Queen Mary University of London. After graduating I went to 
 work in Portugal Telecom Inovação (the R&D company from the incumbent op
 erator in Portugal)\, and then I moved to academia one year later. I start
 ed lecturing in the University of Aveiro (programming courses)\, and in 20
 03 I moved to the Institute of Engineering of Lisbon\, lecturing several c
 ourses: from Electronics to Electromagnetism to Digital Communications.\n
