1 Update from LITNET and the Baltic region Raimundas Tuminauskas Prague, September
2 TOPICS 1. Intro: Life in a small NREN 2. Five years and beyond: where to go 3. Collaborations: national and international 4. Regional network: possible ways forward 5. Conclusions
3 Life in a small NREN Facts and figures 770 own DF backbone, DWDM, 10G Leased DF CBF connection to Poland 50-site regional distribution network G core (LT-PL over the CBF) Peerings over the CBF 876 organizations, including 585 schools Network services: L0-L1 only for advanced users (universities) L2-L3 wide variety Network as a service starting Usual pack of other services: Federation, T&I, Security, Clouds Signed EU structural grants : 0,8M social fund for service development 4,3M ERDF for national infrastructure
4 Five years and beyond Metro fun part Short distances (10s of kilometers) Lots of locations connected over the distribution nodes Concentrating on the backbone leaves metropolitan networks neglected Natural growth topology v.s. orderly network environment New generation virtual network
5 Five years and beyond Easy bits DF connectivity to the Observatory 10G connectivity to regional colleges Top up DWDM : 40 lambdas, ½ of 50GHz grid Some optical switching (non-cdc) Support for aliens and spectrum sharing 10G operational, 100G-ready Optical encryption Upgrade routing platform Raseiniai 36 db 171 ROADM db 25 db db 23 db 107 OA OA DCM ROADM ROADM DCM OSC OSC 10 Local collaboration with the state OSC 11 enterprise Infostruktura since Kaunas node 2010 Proven as efficient, will change more into client-provider relationship 37 db 146 Vilnius
6 Alytus Collaborations International CBF opened the road for international collaboration Currently operates 5 lambdas: (2x, Peerings, Experimental, and Time) PIONER MUX 2 VOA/13 1 DRP1 DRP2 TP #1 1 4 TP/2: G 194.7THz 2 VOA/12: THz OUT2 OUT1 IN2 IN1 TP #2 TP #3 5 TP/2: G TP/3:1 2 10G THz 194.9THz 4 VOA/12:2 3 6 VOA/12: THz 194.9THz AD 4-ch / VOA/ VOA/15 1 DCU 60 DCU 60 1 OA /11 2 OA 2 1 /10 TP #4 5 8 TP/3: G 195.0THz 8 VOA/12: THz TP #5 TP #6 OSC/1:2 SFP 1490nm LITNET 1490nm 3 1 AD 1ch 2 / ODF 2
7 Regional network The network development Porta Optica Study Baltic Ring Study by NORDUNET Baltics and Russia GN3Plus regional study GN4-2 NREN L1 infrastructure assessment 2016 Baltics, Russia, and Belarus GN4-2 regional study 2017 LON 100G HEL 100G TAL 100G AMS 100G HAM Infinera RIG KAU 100G AMS GEN DF FRA Infinera PRA DF POZ Infinera PRA DF 100G
8 Regional network CBF opportunity for NRENs >4500 of NREN >4700 of NREN International DF over CBF Leased lines Peerings Experimental >2000 2x10G 10G 91 TAL 2x10G RIG 470 2x10G HAM 770 POZ Alien 2x10G 1362 KAU POP Peering CBF NREN POP NREN DF
9 Regional network Dark fibre IRU Most obvious choice 370 required v.s. thousands already in place IRU funds or other funds (Interreg) Some unanswered questions: How to couple DWDM system Who will operate the infrastructure Who will provide services What will the network be What uses will be eligible POP Peering CBF NREN POP NREN DF
10 Regional network perspective Way forward : CBF Double infrastructure P K R T H Dark fibre in the region NRENs P K R T H Spectrum Spectrum Spectrum Spectrum L1 Optical sharing sharing sharing sharing services P K R T H Access NREN peerings P K R T H L2-3 connectivity P K Lambda R Lambda T H optical services ensure pan-european connectivity
11 Regional network perspective Another Way forward : 100G NRENs P K R T H P K R T H Dark fibre in the region L1 Optical infrastructure Access NREN peerings P 100G K 100G R 100G T 100G H L2-3 connectivity P K R T H Economy factor is not straightforward
12 Conclusions NREN perspective 1. Own infrastructure lifeline in the uncertain times 2. DF deployment enables rapid advance, but not as rapid as sometimes required 3. Cross-border fibre connections enable closer collaboration with the neighbours 4. connectivity remains essential tool for the R&E
13 Thank you! Any questions?
