ALPHA key issues: overview Next-Generation Capacity upgrade access networks solutions/PHY In-building networks Dynamic Futureapplications capacity allocationTestbeds 2G/3G/B3G integration Contribution to standards Control and management Techno-economics Claus Popp Larsen, Acreo, p3p3 Claus Popp Larsen, Acreo, Next gen. active opt. access networks (AON): Next gen. active opt. access networks (AON): www.acreo.se Latest results of of the ALPHA project Latest results the ALPHA project FTTH Council, FP7 project workshop FTTH Council, FP7 project workshop
  4. 4. What is Active Optical Network (AON)?Home run (AON) Active star (AON) Passive optical network (PON)– Point to point – High bandwidth –Passive network with– Highest bandwidth – High flexibility tree topology– High flexibility – Active equipment in field –Average bandwidth– Most deployed in –Most deployed in Asia and – Most deployed in Europe USA Europe and Korea Claus Popp Larsen, Acreo, p4 Next gen. active opt. access networks (AON): www.acreo.se Latest results of the ALPHA project FTTH Council, FP7 project workshop

FTTx status in Europe (June 2010) Types of player, homes passed Incumbent: 17,4% (high in PT and FI) Municipality/Utility: 9,3% (high in DK and SE) Alternative operators/ISPs: 72% (high in RU and FR) Housing companies and others: 1,4% (high in NL and SE) Claus Popp Larsen, Acreo, p7 Claus Popp Larsen, Acreo, p7 Next gen. active opt. access networks (AON): Active Optical Networks Source: IDATE for FTTH Council Europe www.acreo.se Latest resultsACP 2010 of the ALPHA project FTTH Council, FP7 project workshop
  8. 8. What determines NGOA? OPEX CAPEX Digging costs • Mutually more or Business model less contradictory Regulation • Different for AON Traffic pattern and PON Technical performance Political & societal factors There will not be one size fits all, but we need to understand the differences and similarities for the various solutions Claus Popp Larsen, Acreo, p8p8 Claus Popp Larsen, Acreo,Next gen. active opt. access networks (AON): Next gen. active opt. access networks (AON): www.acreo.se Latest results of of the ALPHA project Latest results the ALPHA project FTTH Council, FP7 project workshop FTTH Council, FP7 project workshop

  10. 10. Measurements on a Swedish FTTH network (Jan–June 2010, 2500 users), symmetricThe success of peer-to-peer technologies: Illegal file sharing: Pirate Bay, etc Commercial content distribution: Spotify, Voddler, NRK, etc File sharing reduces server costs and optimises content distribution Key question: How much traffic is local? Claus Popp Larsen, Acreo, p10 Next gen. active opt. access networks (AON): www.acreo.se Latest results of the ALPHA project FTTH Council, FP7 project workshop

Future options for AON Customer Premises Access Gateway Network Multi Sites Service Sites Home ANS Access GWS ANS Edge Provider Network Sites Edge Sites Core Next Generation Access Network ANS ANS AES PES Network Home Network GWS ANS ANS Home network Core network Network control and management functions edge functions edge functions Home Network Next Generation Access Network Core Network  Mesh-like AON/Ethernet for higher dynamics and flexibility  the access and distribution networks can be merged  Inherently higher resilience without adding cost to network elements (NE)  The possibility of keeping local traffic local e.g. for P2P based content distribution Claus Popp Larsen, Acreo, p11 Next gen. active opt. access networks (AON): www.acreo.se Latest results of the ALPHA project FTTH Council, FP7 project workshop
  12. 12. GMPLS control of multi-layer Ethernet networks Border Border Border Border Q  Demonstrated target network: 802.1Q + Amendments PBB PBB PBB Q PB Q (.1Q, .1ad, .1ah, .1Qay) PB Allows for all resource PBB PB Q reservation scenarios PBB PBB PBB PBB PB Q Border Border Border Border Border Payload Multi-layer Ethernet Headers Multi-layer reservation Principle: Ethernet tunnels in Ethernet tunnels Signalling, routing and path computation allows for automatic Network Elements PBB / PBB / PBB / PB Q setup PBB-TE PBB-TE PBB-TE Claus Popp Larsen, Acreo, p12 Next gen. active opt. access networks (AON): www.acreo.se Latest results of the ALPHA project FTTH Council, FP7 project workshop
  13. 13. Provisioning in interconnected home/access network UPnP QoS (home network) + GMPLS (access)  Provisioned ”pipe” (LSP) reservation in access from home demonstrated at ECOC 2010 in ALPHA booth Claus Popp Larsen, Acreo, p13 Next gen. active opt. access networks (AON): www.acreo.se Latest results of the ALPHA project FTTH Council, FP7 project workshop
  14. 14. Conclusions Many factors determine the shaping of NGOA – the are often mutually contradictory Two topology trends today: Dynamics in distribution network vs consolidation of central offices Traffic in high capacity access networks dominated by peer-to- peer traffic NG AON merges access and distribution into one multi-layer network Provisioning across home gateway demonstrated in interconnected home/access network There will not be one size fits all, but we need to understand the differences and Claus Popp Larsen, Acreo, p14 similarities for the various solutionsNext gen. active opt. access networks (AON): www.acreo.se Latest results of the ALPHA project FTTH Council, FP7 project workshop
