2 The OMEGA project Started 01 January 2008, Ends 31 December 2010 Funded by European Commission FP7 programme 21 partners from industry and academia 8 Workpackages Scenarios, services and techno economics Connectivities Radio communications, Wifi, UWB, 60 GHz (PHY,, Xlayer) Powerline communications (PLY, ) Wireless Optics, visible light & Infra-Red (PHY, ) Inter- convergence layer Architecture security continuity of services Demonstration Dissemination, Training & Standardisation Project website Contact OMEGA info@ict-omega.eu 2

3 Omega Project scope Core scope Network project Connectivities at Gbps Convergence at layer 2.5 Network architecture and security Demonstration of the concept and dissemination Perimeter Use of UPnP for QoS Device management (local/remote) Continuity with access networks 3G/4G, Optical access networks Services Work on the impact of the introduction of new services on HN architecture 3

4 OMEGA driving postulates The final link of the in-house communication will be preferably wireless. The Gbps wireless is not QoS acceptable within more than one room. Electrical power plugs is the easiest medium term way to bring wire line connectivity in Europe. IP-layer cannot manage PHY impairments to QoS acceptance while still being the de facto standard for the connected home. OMEGA network and devices have to be green 4

5 Key requirements : Race to Gbps 2 major trends over the last decades: i. media richness of the services available to the end consumer has a constant increase rate of about 8% per year for the last century. need of Ultra BroadBand (Gbps) at home to handle future services such as 3D. ii. bandwidth ratio between indoors and access ranges from 5 to 10. The rolled out FTTH access is 100 Mbps symmetric implies thus Gbps indoors. major bottleneck risk that the home network jeopardizes the Quality of Experience of the future services. 5

6 Key Requirements: Compatibility Compatibility with future access networks Continuity must exist among these networks increase of data rates in the access (optical fibre) packet oriented handling of the QoS Support of legacy devices without degradation Some the terminals may be OMEGA end devices The other terminals are legacy devices may be compatible with the OMEGA technologies WiFi n, HD PLC, UWB, optical wireless, radio at 60 GHz may be not compatible with them Compatibility with future middleware Several middleware solutions already exists but there are not interoperable UPnP/DLNA, DPWS, IGRS, BONJOUR, HAVI 6

13 Inter- sub-layer data format Additional header is inserted >>> standardisation is mandatory! 13

14 Inter security End-to-end encryption Procedures for establishing trust and membership in the Home Network Incorporation of Trusted-Computing principles 14

15 Inter QoS control Admission control for flows Frames marked for QoS Resource reservation More support for QoS requirements of flows sourced from legacy devices Help for dynamic bandwidth availability 15

16 Industrial products Gigle networks has an intelligent multi- PHY switch (PLC, coaxial, WiFi, Ethernet) But there is no standardization 16
