The Silk Project CCIRN Briefing
Silk O/v – Background • In 2001, NATO Networking Panel agreed installation of Regional Network for NISs of the Southern Caucasus and Central Asia • Would connect existing NRENs into GEANT • Start with own resources – $2.5 M for 3 yrs • Allow to be extensible by others
Silk O/v– Countries and Sites X X X X X X X X X
Silk O/v – Basic Technology • VSAT Technology • DVB Shared Channel from hub • SCPC from remotes • Uses Eurasiasat strapped beam transponder • Hub in Hamburg with 5.6m dish • Remotes in 8-9 NISs, each with • 2.4 or 3.8 m dishes • Routers connecting to NRENs • 155 GB Content Engine • Routers and Silk NOC part of Silk Network
Silk O/v – Architectural Overview • Hub Earth Station at DESY accesses European NRENs and Internet via GEANT • Provides direct International Internet access • National Earth Station at each Partner site • Operated by DESY • Provides Internet access via satellite • Additional earth stations from other sources • Routers for each Partner site • Linked on one side to the Satellite Channel • On the other side to the NREN

Silk O/v – Early Planned Silk Bandwidth Planned Silk total bandwidth from NATO Per half year Total bandwidth in Mbps 30 25 20 15 10 5 0 02/H2 03/H1 03/H2 04/H1 04/H2 05/H1
Status - Current Status • All original 8 sites operational • We are currently operating with 15 MHz Currently 17.4 Mbps DVB, 4.4 Mbps transmit • The caches currently save about 10% B/w • Caches only store pages own E/s requests • Have implemented CIR quotas
Status - Governance • Have set up Silk Board (SB) • Silk Managers • Funders • One representative each Silk country • Invited Guests • Set up Silk Executive Committee (ExCo) • Silk Managers • One representative from each region • SB meets 3 x per year, mainly in Silk countries • ExCo has 2 Teleconferences per month
Status – Co-funding • NATO has put in $2.7M • EC funds SPONGE management at $220K • DESY houses hub and runs NOC at $400K • Cisco Donation now worth $550K • ISOC donations for workshops - $120K • Have held one so far, but sent people to CEENET one • NSRC donations for books/WLAN - $50K • IREX is putting in – $30K • Soros/Eurasiasat travel - $30K • Many are funding projects that build up national infrastructure using Silk • Soros, EC Tacsis, UNDP, World Bank
Status – Personal Communications • Have provided 2 Cisco phones per site • UCL operates voice server • UCL has put dial-out on server to very limited outside lines • Used regularly for ExCo meetings • Have done extensive H.323 usage • Included Heads of State and NATO SecGen • Distance lectures including World Bank • Requires using CIR in both directions
Extending Silk – Possibilities • Have started talking to other funding agencies to provide extension • Could be just extra national bandwidth • Could be extra VSATs – now adding Kabul • Could be Receive-only earth stations • Could be extra networks on Silk routers • Could be alternate activity like IPv6 • Early discussions look promising • IREX and Soros will provide funds • University of Central Asia will use it via funds from Aga Khan.
Extending Silk – Workshops • Doing 6 workshops – mainly in Russian • Mainly from ISOC funds, one co-funded ANW from NATO and CEENET • Security – Armenia, June • Wireless – Hungary, August • Distance Education - Azerbaijan, September • IPv6 - Hamburg, September • DNS, Registration, address allocation - Kazakhstan, November
IPv6 Activities • Countries expressed interest in getting experience – but not at cost of IP4 service • Fairly easy to do with dual-stack router and tunnelled IPv6 • Native IPv6 needs special hardware for DVB • ESA/IABG agreed to provide IPv6/DVB H/w • ESA providing some B/w for testing • 6NET providing some B/w for dissemination • Each NIS will provide small IPv6 facilities
Longer Term – Future Steps • NATO Support should continue after 7/05 • But at a reduced rate with declining funding • Co-funding is vital to many others also • Hard to achieve with these countries • Form of Connectivity will become hybrid • Satellite necessary for some locations • Fibre will come into some sites; already looking at terrestrial possibilities • Other satellites cheaper than this Silk solution – particularly in Caucasus
Longer Term – Future Steps -2 • Most terrestrial solutions go through Russia and perhaps Kazakhstan • Will become cheaper, but acceptable politically? • EC starting specific Caucasus Programme • Perhaps Caucasus connects by fibre to GEANT, some others stay satellite • Discussing Central Asia plans with APAN/CCIRN • Perhaps there will be links to Pacific Rim • Should use satellite broadcast capability • Both Multicast and Broadcast caching • Will make proposal to NATO Science Committee in October, and also to EC (not only IST)
