Agenda : 9.00AM - 9.10AM: Introduction; Bill Efthimiou (Chair/AARNet)
9.10AM - 9.50AM: VoIP and Video in Brazil; Alex Galhano Robertson (RNP)
9.50AM - 10.30AM: Global Real-Time Communications - (GRTC-document); Bill Efthimiou (Chair/AARNet)


The majority of Research and Education institutions have today deployed IP based Rich Media Communications, which may come in the form of, Telephony systems, traditional room based Video, Video Conferencing and/or high end TelePresence solutions. This is certainly the case within Australia, but is also the case in many other parts of the world and certainly within R&E. This talk is about detailing recent events and developments within the NREN space facilitating cross-Institution Rich Media communications using disparate commercial and open source solutions.


Bill Efthimiou joined AARNet in May of 2010 after having worked the previous 5 years as a Principal Consultant at a Systems Integrator, designing, implementing and managing Unified Communications infrastructures and networks for businesses. Previous to this Bill worked for Cisco Systems Technical Assistance Centre in Sydney for 5 years. Here he spent much of his time troubleshooting and supporting very large and complex customer networks. Bill's IT career spans over 24 years during which time he has held many System Administration and Consulting roles.

Since joining AARNET Bill has been busy designing and developing Next Generation Multimedia Infrastructure services, mostly based on SIP. Bill is currently responsible for developing and operating the AARNet Unified Communications eXchange and is also evangelising the adoption of standards based signalling, audio & video codecs throughout the Research and Educations community globally. This effort is being carried out with a view to make ubiquitous video calling across all types of video endpoints within the community a reality.

11.00AM - 11:30AM: What is NRENum.net all about; Peter Szegedi (TERENA)


The NRENum.net Service is an end-user ENUM service run by TERENA and the participating NRENs (National Research and Education Networking organisations) primarily for academia. NRENum.net is considered as a complementary service and a valid alternative to the Golden ENUM tree. The domain "nrenum.net" is being populated in order to provide the infrastructure in DNS for storage of E.164 numbers. The NRENum.net Service includes the operation of the Tier-0 root DNS(s) and the delegation of county codes to NRENum.net Registries.

Having gained partners from Europe, North America, Latin America and Asia Pacific, NRENum.net has grown to a global, production-grade, community service in recent years. As one of the key building blocks of global unified communications, it is TERENA's mission to coordinate and continuously enhance the service for the benefit of the entire research and education community in a sustainable manner.


Peter Szegedi joined TERENA in January 2008. He is one of the Project Development Officers who develop and manage the task forces and contribute to technical projects and strategic programmes. He is currently the secretary of three TERENA task forces; TF-Storage (data storage), TF-Media (rich media management), and TF-NOC (network operation centres), as well as the coordinator of the e2e network architectures and real-time communications related activities. Peter looks after the NRENum.net service, the Trusted Cloud Drive pilot and the Open Educational Resource portal pilot at TERENA. He is the task leader of the EC-funded GN3+ (GEANT) project Testbed as a Service activity. Peter Szegedi received his MSc degree in Electrical Engineering at Budapest University of Technology and Economics, in Hungary, in 2002. He then worked towards a PhD at the Department of Telecommunications. Peter worked for Magyar Telekom Plc. (the largest incumbent service provider in Hungary) as a Research and Development Manager between 2004 and 2008.
