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

http://www.ist.bg/

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

Simplified transitionmethodology 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

Quick Summary(1)

Simplified transitionmethodology 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

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)



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)

Several ISTF routers have dual-stack configuration:

IPv6 deployment in ISTF’s network



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)

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)

IPv6 enabled services at ISTF (2) Network monitoring tools (Looking Glass,

SmokePing, RANCID, ntop, etc…)



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 !!??



15

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’




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)



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? ;-)
