  1. A New Generation of Multi Service Access Networks: Results of MUSE Phase I Peter.Vetter@Alcatel.be AccessNets 2006 Athens, 4-6.09.2006

  2. Outline • Introduction to MUSE • Access Architectures and Platforms • First Mile Solutions • Residential Gateways • Lab Trials • Summary and Outlook

  3. MUSE Overall Objective Multi service access network that provides • secure connectivity between end-user terminals and edge • in a multi-provider environment • at a low cost for every European citizen. Network Service Provider Network Access Provider Access Node Customer Premises First Mile NetworkService Provider Aggregation network Edge Node Internet Service Provider Residential Gateway Application Service Provider

  4. Research Inst. & Universities IBBT Inria TU Eindhoven Budapest University (BUTE) ICCS/NTUA HHI Lund Institute of Technology (LTH) ACREO Univ. Carlos III de Madrid University of Essex Partners Phase I: 2004-2005 Phase II: 2006-2007 36 partners -100 PY/year System vendors Operators (**) Component vendors SME Aarhus BB society (*) (*) (*) (*) Only in phase I (**) Only in phase II

  5. Outline • Introduction to MUSE • Access Architectures and Platforms • First Mile Solutions • Residential Gateways • Lab Trials • Summary and Outlook

  6. Ethernet LAN (trusted environment) Ethernet in Access (public network) • No authentication • AAA • Configurable MAC@ • Conflicts, spoofing • Anti-spoofing mechanism • Bridge learning - Broadcast of some initialisation messages (ARP, DHCP, PPPoE) • DOS attacks • Confidential info to other usersor competing providers • Secure and scalableconnectivity models • Model 1 (L2 forwarding) • Model 2 (L3 forwarding) • No QoS • QoS framework Issues when using Ethernet in Access

  7. Model 1: L2 Ethernet forwarding Cross connect VLAN (stacking) or Bridging Ethernet MAC@ IP termination BRAS or Edge Router bridged NSP/ISP NAP CPN CPE NSP/ISP EN Ethernet aggregation network routed(IPv4/IPv6) NSP/ISP CPN EN ASP CPE AN

  8. Model 2: L3 IP forwarding IP aware bridging (IPv4/IPv6 ) IP termination BRAS or Edge Router bridged NSP/ISP NAP CPN CPE NSP/ISP EN Ethernet aggregation network routed(IPv4/IPv6) NSP/ISP CPN EN ASP CPE AN

  9. Multi Service AccessQoS control • QoS is key in multi-service access • End-to-End QoS solutions (e.g. IntServ) • commercially failed because of complexity • Priority based QoS (e.g. Diffserv) • works in Core Networks with sufficient capacity, • not suited for Access & Aggregation => Resource admission control in Access & Aggregation needed Edge Node Access Node

  10. Network Resource Controller (NRC) • View of flows and BW already allocated • Admission control after request • Configures policers at borders NRC QoS control • Pre-provisioned pipes Edge Node Access Node

  11. Outline • Introduction to MUSE • Access Architectures and Platforms • First Mile Solutions • Residential Gateways • Lab Trials • Summary and Outlook

  12. First Mile • High BW at lower cost • Low cost CWDM • Radio over Fibre (SM, MM) • VDSL over Fibre • XL PON • DSL Dynamic Spectral Mgt. • UWB over DSL

  13. xDSL Loop Qualification and Monitoring • Line testing integrated in DSL System • Assessment of loop quality and noise environment • Integration in network management for provisioning work-flow Subproject C: EAB, TI, TNO, TS, LTH

  14. Outline • Introduction to MUSE • Access Architectures and Platforms • First Mile Solutions • Residential Gateways • Lab Trials • Summary and Outlook

  15. Internet serv Tripleplay services Media SIP TR69 IP ETH PHY Residential Gateway NT12 ST NT2 CPN NT1 Subscriber L ine ST’ TA U R S T2 T1 TR69 SIP DHCP Management Control IP ETH PHY QoS Management Data

  16. Outline • Introduction to MUSE • Access Architectures and Platforms • First Mile Solutions • Residential Gateways • Lab Trials • Summary and Outlook

  17. Lab Trials • Model 1: Ethernet Forwarding • Model 2: IP Forwarding Subproject C: Ericsson, TNO, ACREO, IFX, Robotiker, TI, TS, LTH, BUTE Subproject B: Alcatel, Thomson, DT, TID, STM, BT, IBBT, INRIA, NTUA

  18. Optical Access Integrated Lab trial Subproject D: HHI, TU Eindhoven, Univ. of EssexLucent Technologies, PTI, FT, UC3M

  19. Outlook phase II • MM service intelligence in access • Fixed Mobile convergences Multimedia Mobile BB Access MUSE Summary • Building Multi Service Access with Ethernet • L2 or L3 forwarding model • QoS guarantees by network resource control • Increased Bandwidth on First Mile • Residential Gateway Suited for Triple Play • Demonstrated in Lab Trials
