Slide 2

ISTF – The Bulgarian NREN

  • Main objectives

    • provision of high-quality networking services to Bulgarian academic & research institutions

    • interconnection with the Pan-European and world research networks (GÉANT2, Abilene, TEIN2, etc.)

    • dissemination of new information technologies among users from the educational, research, and cultural community

6DISS International Conference, 5 Mar '06, Kopaonik, Serbia & Montenegro

Slide 3

ISTF – The Bulgarian NREN (2)

  • Network topology

    • 155 Mb/s international connection to GÉANT2

    • over 1 Gb/s total connections with external Bulgarian peers

    • 50 – 100 Mb/s national backbone

    • covers over 10 cities

    • 20+ universities, the Bulgarian Academy of Sciences, the National secondary schools network are connected

    • Network Operations Centre hosted and operated by the Institute for Parallel Processing – BAS

Slide 4

Quick Summary(1)

Simplified transition

methodology strategy

  • Get an IPv6 address space allocation

  • Deploy an IPv6-enabled router

  • Arrange external IPv6 connectivity

  • Enable internal routing

  • Deploy security measures and enable

    basic networking services

  • Enable IPv6 to end-systems

  • Active IPv6 to applications

Slide 5

Quick Summary(1)

Simplified transition

methodology strategy as implemented in Bulgarian NREN:

  • Get an IPv6 address space allocation (2001:4b58::/32 )

  • Deploy an IPv6-enabled router- yes

  • Arrange external IPv6 connectivity - yes – to GEANT2 network

  • Enable internal routing – partially - over three major links

  • Deploy security measures and enable basic networking services

    – using the same ACLs as for IPv4

    – no IPv6 specific security measures undertaken so far – work in progress;

    – only DNS and web services are IPv6 enabled

  • Enable IPv6 to end-systems – partially on the NOC LAN – FreeBSD, Linux, Windows XP

  • Active IPv6 to applications – future work in progress

Slide 6

RIPE IPv6 allocations for Bulgaria

  • Currently only three IPv6 prefixes are allocated by RIPE to Bulgarian LIRs

    • bg.mtelnet 20040331 2001:1ac8::/32

    • bg.nat 20040406 2001:1ae0::/32

    • bg.unicom-b 20050201 2001:4b58::/32

  • The first two allocations are for major Bulgarian ISPs (MTel and Evolink)

  • The third allocation is for the Bulgarian NREN (ISTF)

  • 6DISS International Conference, 5 Mar '06, Kopaonik, Serbia & Montenegro

    Slide 7

    Native international IPv6 connectivity in Bulgaria

    • So far, from these three allocated IPv6 prefixes only ISTF advertises its own one (2001:4b58::/32,origin AS6802) worldwide:

      • through the SEEREN link Sofia-Athens(01/Feb/2005 – 17/Mar/2005)

      • through the GÉANT2 link Sofia-Budapest(from 17/Mar/2005 onward)

    6DISS International Conference, 5 Mar '06, Kopaonik, Serbia & Montenegro

    Slide 8

    IPv6 deployment in ISTF’s network

    Several ISTF routers have dual-stack configuration:

    sofia-broder:

    cisco7301-ios C7301-JS-M, Version 12.3(11)T3

    sofia-access:

    cisco7206-ios C7200-JS-M, Version 12.3(11)T2

    tarnovo-access:

    cisco2691-ios C2691-ADVIPSERVICESK9-M, Version 12.4(4)T1

    plovdiv-access:

    cisco2691-ios C2691-ADVIPSERVICESK9-M, Version 12.4(4)T1

    pleven-access:

    cisco2621xm-ios C2600-IS-M, Version 12.3(3)

    6DISS International Conference, 5 Mar '06, Kopaonik, Serbia & Montenegro

    Slide 9

    IPv6 deployment in ISTF’s network

    • The central node at IPP-BAS is fully IPv6 enabled, including the NOC and part of the LAN of IPP-BAS (most internal traffic is actually IPv6)

    • IPv6 traffic is also carried over three major links in the ISTF internal backbone:

      • Sofia – Veliko Tarnovo

      • Sofia – Plovdiv

      • Veliko Tarnovo – MU Pleven (link configured yesterday)

    Slide 12

    IPv6 enabled services at ISTF

    • Primary/secondary DNS for acad.bg domain:

      • ns6-a.acad.bg IN AAAA 2001:4b58:acad::3

      • ns6-b.acad.bg IN AAAA 2001:4b58:acad::9

  • Several WWW sites:

    • http://netmon.acad.bg (network monitoring tools portal)

    • http://bis-21pp.acad.bg (site of the Bulgarian IST Centre of Competence in 21 Century – BIS-21++)

    • http://webmail.acad.bg (web access to local mailboxes)

  • 6DISS International Conference, 5 Mar '06, Kopaonik, Serbia & Montenegro

    Slide 13

    IPv6 enabled services at ISTF (2)

    • Network monitoring tools (Looking Glass, SmokePing, RANCID, ntop, etc…)

    Slide 14

    ISTF’s international IPv6 traffic volume

    • ISTF’s international IPv6 traffic volume for December 2005 amounted to:

      • 170 MB transmitted to GÉANT2

      • 470 MB received from GÉANT2

  • When compared to ISTF’s international IPv4 traffic, it accounts for:

    • ~ 0,0027 % of the total egress traffic

    • ~ 0.0087 % of the total ingress traffic

  • IPv6 traffic is rather low, but … what is the IPv4/IPv6 traffic ratio in other NRENs !!??

  • 6DISS International Conference, 5 Mar '06, Kopaonik, Serbia & Montenegro

    Slide 15

    IPv6 deployment in ISTF’s network

    • Setbacks:

    • Still not enough resources for end-user deployment at other places

    • No enough qualified staff

    • No sufficient motivation to deploy IPv6 ( not found The IPv6 killer application … yet )

      While we are working on the first two, we can hardly influence the lack of The ‘Killer Application’

    6DISS International Conference, 5 Mar '06, Kopaonik, Serbia & Montenegro

    Slide 16

    IPv6 deployment in ISTF’s network

    • Little Tricks !

    • In order to stimulate IPv6 deployment in the Regional Centres we announced and provide unlimited IPv6 traffic bandwidth to the Regional Centres (whereas IPv4 traffic bandwidth is limited according to the respective contracts with the RC)

    6DISS International Conference, 5 Mar '06, Kopaonik, Serbia & Montenegro

    Slide 17

    The future

    • Further deployment at the national backbone is planned, eventually to cover it completely

    • Making IPv6 available to a larger portion of the end-users, especially where the protocol shows its strengths (e.g. the integrated security)

    • Establishment of IPv6 peerings with Bulgarian ISPs is foreseen, possibly marking the beginning of a true nation-wide IPv6 backbone

    • The progress depends very much on the available hardware and software, which is still inadequate – have a router to spare? ;-)
