Silk O/v – Background
In 2001, NATO Networking Panel agreed installation of Regional Network for NISs of the Southern Caucasus and Central AsiaWould connect existing NRENs into GEANTStart with own resources – $2.5 M for 3 yrsAllow to be extensible by others

Silk O/v – Basic Technology VSAT Technology
DVB Shared Channel from hubSCPC from remotesUses Eurasiasat strapped beam transponder
Hub in Hamburg with 5.6m dishRemotes 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 – East Beam Transponder Map
Silk O/v – Schematic of the Silk System
Silk O/v – Architectural OverviewHub Earth Station at DESY accesses European NRENs and Internet via GEANT
Provides direct International Internet access
National Earth Station at each Partner siteOperated by DESY
Provides Internet access via satellite
Additional earth stations from other sources
Routers for each Partner siteLinked on one side to the Satellite Channel
On the other side to the NREN

Status - Current Status
All original 8 sites operationalWe are currently operating with 15 MHz Currently 17.4 Mbps DVB, 4.4 Mbps transmit
The caches currently save about 10% B/wCaches only store pages own E/s requests
Have implemented CIR quotas
Thinking the future

CCIRN – Silk BriefingJuly 3 2004
Status - GovernanceHave set up Silk Board (SB)
Silk ManagersFundersOne representative each Silk countryInvited Guests
Set up Silk Executive Committee (ExCo)Silk Managers One representative from each region
SB meets 3 x per year, mainly in Silk countriesExCo has 2 Teleconferences per month

CCIRN – Silk BriefingJuly 3 2004
Status – Co-funding
NATO has put in $2.7MEC funds SPONGE management at $220KDESY houses hub and runs NOC at $400KCisco Donation now worth $550KISOC donations for workshops - $120K
Have held one so far, but sent people to CEENET oneNSRC donations for books/WLAN - $50KIREX is putting in – $30KSoros/Eurasiasat travel - $30KMany 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 siteUCL operates voice server
UCL has put dial-out on server to very limited outside lines
Used regularly for ExCo meetingsHave done extensive H.323 usage
Included Heads of State and NATO SecGen
Distance lectures including World BankRequires 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 KabulCould be Receive-only earth stationsCould be extra networks on Silk routersCould be alternate activity like IPv6
Early discussions look promisingIREX and Soros will provide fundsUniversity of Central Asia will use it via funds from Aga Khan.

Extending Silk – Workshops
Doing 6 workshops – mainly in RussianMainly 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

CCIRN – Silk BriefingJuly 3 2004
IPv6 Activities
Countries expressed interest in getting experience – but not at cost of IP4 serviceFairly 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

CCIRN – Silk BriefingJuly 3 2004
Longer Term – Future Steps
NATO Support should continue after 7/05But at a reduced rate with declining funding
Co-funding is vital to many others also
Hard to achieve with these countriesForm 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
Thinking the future
36
CCIRN – Silk BriefingJuly 3 2004
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/CCIRNPerhaps 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)
