  3. Open Access, request 1 • Housing sector • Satellite antennas • Convergence • Independent passive infrastructure (SB) • Communes • Independent passive infrastructure (Stokab) • Independent link level (linköping) • Road analogy

  4. Value ladder of public administration • Direct return on Investment • Indirect RoI via lower own costs for communication • Indirect RoI via tax revenues • Indirect RoI via better quality of life and less costs for social welfare

  5. Open Access, request 2 • Operator-neutral: Connect to the service provider of your choice • Departments, universities • Commercial providers • Shared access infrastructure to cut costs • Independent: Anyone can act, noone can block: first mile rather than last mile

  6. Open Network interfaces • Empowering different (natural) actors to build networks together • Increasing horisontal competition as opposed to vertical • Building new value chains • Exploiting local business models

  7. Exchange point centric topologies • As opposed to traditional vertically integrated operator centric topologies • Cooperation with real-estate owners, infrastructure owners and different kinds of service providers

  9. What about traditional operators? • Attitude depends on market position • Incumbents negative • Second operators positive • Local entrepreneurs wants it all (gatekeepers) • Professional maintenance necessary • WLAN market slow to take off • Service level guarantees a concern

  10. What do regulators think? • Independent regulators are positive • Less independent regulators often protect the incumbent

  11. Value chains, actors and business models • Passive infrastructure owners • lease physical connections • Access operators • operate level 2, charge users for connecting and service providers • ISPs operate level 3 • Operate Internet network and application services • Content providers/distributors • PSTN gateways (e.g. digisip) • TV/Video (e.g. CanalDigital) • Databases, GIS, weather forecasts, games,.... • Users • pay and consume

  12. Test beds for • Triple Play, i.e. integrated video/tv/vod, voip and Internet services, • Support for mobility of terminals and sessions • Access network issues (AAA, shared access networks) • Exchange point issues (e.g. peering of public multicast traffic)

  13. Components in the test bed • Service provision • SSVL (AS8973) • Cooperation with several service providers (Digisip, Song, Tele2, Telia, Telenor..) • Residential services (Svebo), Medical Service provision (HU) • Access networks • KistaIP.net (Fiber to the Home) • StockholmOpen.net (WLAN) • Privat GSM/GPRS-nät (GSM/GPRS) • LaponiaOpen, Luleå, Skellefteå, Sundsvall, Uppsala • Traffic Exchange points • Solix (plus BolIX, LaoIX, MozIX, NicIX, RwaIX) • Optix • Core, Long-haul • BalticOpen.net, fiber link to Ventspils, Latvia • Link to the emerging global optical research network via KTHNOC/Amsterdam

  14. SSVL (AS8973) • TSLab operates a private ISP-network in which the SCINT and TSLab test beds are deployed • Support for (m)ipv4 och ipv6 • DNS, DHCP, AFS,… • Migration strategies ipv4 -> ipv6 are explored

  15. www.stockholmopen.net • 150 km LAN • 8 operators (2 private) • 80 access points • >1500 users Access points in • Apartments (KistaIP) • Public places (house of culture, city hall • Shopping center (KistaGalleria) • Arenas • campuses • Rural areas (archipelago) • Open Internet exchange points (Solix)

  16. WLAN-access network StockholmOpen.net • The network designed by KTH/TSLab • Backbone deployed and operated by KTH • Coverage • Kista (Campus, KistaGallerian) • Stockholm City (Kulturhuset, Vinnova) • The Archipelago  (Sandhamn, Utö) • www.stockholmopen.net • http://csd.ssvl.kth.se/~csd2004-team17/

  17. Housing network KistaIP.net • KTH/TSLab operates a pilot owned by Svebo in the KistaIP housing area (www.kistaip.net), including • IPTV via Solix from Telenor/Canal digital using i3micro-set top boxes • VoIP via Labs2/Digisip • A choice of Internet Service Providers • http://csd.ssvl.kth.se/~csd2004-team15/

  18. Regional distributed internet exchange, Solix  • KTH/TSlab operates the Kista node, one of five nodes in Kista, Solna and the inner city of Stocholm • Partners include Telenor/Utfors, Song Networks, Lidnet and KTHNOC • Solix offers interconnection of access network owners and service operators • www.stockholmopen.net/solix/ • R&D on IX-technologies based on level2, level3 and mpls/gmpls in progress • http://csd.ssvl.kth.se/~csd2004-team14/
