Towards a Nation-wide Fibre Footprint in Research and Education Networking

situation in ren design
Situation in REN design
  • Network design is on the top of design levels hierarchy: ICs, cards/units, computers, networks, and is relatively new. WAN/MAN design is still less developed (mainly in consequence of previous long-term monopolies).
  • Traditional building elements (procured) are data transmission services, routers, terminals, etc.
  • Traditional network function is to provide best effort IP connectivity
  • New building elements: dark fibres, optical transmission equipment, switches
  • New network function: provide E2E circuits

multi vendor network design
Multi-vendor network design
  • Multi-vendor networking is necessary for feasibility in multiple domain
  • Multi-vendor networking is necessary in general case for cost effectiveness also in single domain
  • Standards, Multi-Source Agreements (MSA), interoperability, etc. gives you independence on one vendor (in design, reparation, upgrade, etc.) and allows you to buy best equipment in each category

fibre is strategic asset
Fibre is strategic asset
  • Fibre infrastructure has been recognised as strategic asset for research and education networking
    • In some countries, states or regions in Canada, Europe and USA since 2000
    • In USA (national scale) since 2003
    • in EU (union scale) since 2004 (GN2)
  • Customer Empowered Fibre(CEF) networks are emerging technology, that gradually changes network topology, architecture and services from bottom of hierarchy to top

lengths of dark fibres in rens
Lengths of dark fibres in RENs
  • More than 20 000 km in Europe

(plus some fibres for GN2 and GN2 testbed)

  • About 33 920 km in USA

(including National LambdaRail)

  • About 6 700 km in Canada
  • NFF contracted in Australia ….

cef networks and industry support
CEF Networks and industry support
  • Government support of network research should prepare investment opportunity and should support national/federal/union industry development
  • Traditionally this means support of carriers and router vendors
  • For CEF Networks this means rathersupport of fibre cable vendors, companies laying fibre cables with maintenance, transmission equipment vendors etc.
  • Optronics vendors now are becoming aware of the non-carrier (enterprise, RENs) market for their gear
  • =CEF Networks brings new relation between network research and vendors

economics decides
Economics decides
  • Dark fibres brings progress to REN design and subsequently to WAN design generally (and than in competition winner takes nearly all)
  • Strategic importance of getting fibres has been recognised
  • Comparison of temporary dark fibre and lambdas prices is usable for very partial view only and cannot solve problem in general. Economics decides, but not naïve economics.
  • Some reasons: uncertain number of lambdas, period of using, future upgrade of the transmission rate, topology changes, uncertain future economical conditions, unexpected new possibilities, …
  • Actual result: some managers build CEF Networks and others study the problem…

why dark fibre for rens
Why dark fibre for RENs ?
  • Freedom in REN design
  • Getting fibre means controlling the network
  • Independence on carriers and on router vendors
  • Fixed costs of long-term use
  • Transmission capacity up to Tbps
  • Cost-effective ways of fibre sharing (WDM, TDM, …)
  • Expensive dark fibres can be shared by non-profit partners
  • Multiple wavelengths possible (e.g. 1 – 256)
  • Multiple fibres in cable, multiple ducts in way…
  • Equipment selection, moving, design, …..

how to go from telco services to dark fibres
How to go from telco services to dark fibres
  • Procure dark fibre independently and before lambdas procurement
  • Prefer agreements on long term lease with discounts instead of IRU (disadvantages of IRU are prepayment, taxes and risk of bankruptcy)
  • Do not relay on one provider only, maintain concurrency (for price and for first mile acquiring)
  • If price is not excellent, use annual contracts and re-procurement
  • If dark fibre line is not offered but exists, use annual contract for lambda(s) and re-procure dark fibre

dark fibre deployment in rens
Dark fibre deployment in RENs
  • Increasing and world-wide deployment of dark fibre (acquisition of dark fibres instead of SDH or lambda services) – without moving back
  • Increasing number of customer premises connected by fibre: to achieve this is more difficult problem than intercity fibre acquisition
  • Lease of fibres: good prices are 0.4 Euro/m/pair/year for G.652 or 0.5 Euro/m/pair/year for G.655 , including maintenance
  • Building first mile 12 fibre lines: about 30 Euro/m in ground (6 month for delivery), and about 10 Euro/m in air (3 month for delivery)

cef network architecture will be new
CEF network architecture will be new
  • Prefer network architecture with NIL (singlespan) lines and without overlaying (concurrent) fibres
  • KIS rule for fibres: Keep It Short, including connections crossing state borders
  • Realization oflambdas by own equipment and fibres for long distance data transmission
  • Search actively for new fibre providers (railways, roads and highways, electric power, fuel, gas and heat distribution companies, cable TV companies, etc.)
  • Search actively for regional authorities and local boards cooperation on laying first mile fibre cables

photonic air links pal
Photonic Air Links (PAL)
  • Gigabit transmission rates are possible in free space
  • Customer Empowered Photonic (CEP) Networks are expected: fibre+PAL
  • PAL is used usually between buildings (fan-out of photonic transmission to end users in some area)
  • Transmission rate: from 10 Mbps up to 2.5 Gbps, distance 100 m – 4000 m, costs 1500 – 30 000 Euro
  • DIY solution of PAL 10 Mbps (for example for students to home – costs 150 Euro)
  • Microwave backup (probably up to 622 Mbps) of PAL (on L1 level) is possible – e. g. for foggy weather

cheaper international f ibre f ootprint iff
CheaperInternational Fibre Footprint (IFF)
  • KIS: Connect dark fibres used by NREN by a short cross-border fibre lines (called also Near over Border - NoB)
  • Use WDM equipment on national and cross-border fibres for implementation of international lambdas between end users
  • This KIS approach avoids some double payments of fibres or lambdas (parallel lines are paid by NREN and DANTE), in the biggest item of budgets
  • Such change of networking strategy is difficult, needs research and testbeds

pc light
PC Light
  • Design Kit for wide area fibre networks, based on racked PCs with build-in optical amplifier modules
  • Multi-vendor (multi-source) building elements
  • Preliminary comparison of OA (EDFA) costs:
    • OA from „ISP vendor“: 40 000 USD
    • OA from „optical vendor“: 18 000 USD
    • OA from „module vendor“: 2 500 USD (two OA in module)
    • OA from Integrated Circuit vendor: ??? (forthcoming)
  • OA costs are the biggest item in long distance transmission systems costs (e.g. 60%)

=> PC Light helps to radically change WAN/MAN costs

edfa 2in1 pc light equipment example
EDFA 2in1: PC Light equipment example
  • PC with build-in OA EDFA booster and preamp
  • Successfully used for NIL GE connection from Plzen to CzechLight in Prague by dark fibre pair (159.4 km, 36.7 dB) since May 2004
  • One Side Amplification (OSA NIL approach): this equipment is placed in Prague only. No OA equipment is placed in Plzen, so we expect lower service costs and higher availability (we have 24/7 staff in Prague only)
  • Advantages: low cost, low size (1U), low power consumption, Linux, SNMP, reach up to 225 km, possibility of development, ….
