Technological and financial aspects of URAN project Dr. Vladimir Galagan Head deputy of URAN Technical Commitee
Structure • Star equal structure with center in Kiev • Regional nodes in the bigger regional cities • Regional nodes in the technical Universities of Ukraine as rule • Clear channel digital leased connection between nodes
Long distance channels • Digital clear channel lines • Ukrtelecom is Network operator • E1 to E3 or ATM over STM155 • Channel speed from 64 KBPS at start and up to 2 MBPS • Special price for budget organization (<2.4 times)
Internet connection • Main symmetrical IP connection over Ukrtelecom • Bandwidth from 64 KBPS at start and up to 2 MBPS • Multichannel connection with downstream over satellite • Asymmetrical bandwidth (4:1)
User connection solutions (1) • 64...128 K connection to users in Kiev • 64...128 K connection to users in cities with E1 network on the next steps (Dnipropetrovsk, Odessa) • Leased physical line inside of cities (64...128K)
User connection solutions (2) • Short range synchronous modems based on HDSL technology • Leased tonal channels for long distance user connections • Microwave channels • Ethernet bridges
Equipment • Cisco routers in backbone • Cisco routers and PC based routers in users. • Intel platform for servers • Short range modems based on HDSL technology
Software • Cisco Internetworking operating system on IP and TCP level. • FreeBSD and Linux for servers. • Linux and Microsoft intranet in users networks
Protocols • TCP/IP • Frame relay • PPP • SNMP • Ethernet • BGP, OSPF
Network services for users (1) • “Secondaring“ users name servers. • “Relaying “ the E:mail flow (on users demand). • Network addresses Translations (on users demand)
Network services for users (2) • Including undepended IP addresses users blocks in AS URAN (on users demand) • Access lists (on users demand) • Shaping of bandwidth (on users demand)
Conditions of payment for users • Payment for the traffic • Different prices for day and night time traffic (1:4). • Connections over E1 Network without start payment. • Average month payment for the 64K connection with 30% traffic - $380 (compare to $600 in commercial providers in Kiev)
Financial aspects - planned • Stage 1 – (steps 1 and 2) - $150000 from NATO, $58000 from Ukraine universities, • Stage 2 – (steps 3 and 4) - $100000 from NATO, $220000 – from Ukraine
