Options to get the DF

RoEduNet case

The deal

Costs

6 year of operation

IRU

IRU - the exclusive and unrestricted (indefeasible – cannot be overturned) right to use the relevant capacity (including equipment, fibers or capacity) for any legal purpose

DF IRU - the exclusive and unrestricted (indefeasible – cannot be overturned) right to use a pair of fibre (from a cable) for any legal purpose

Period – at least 10 years

IRU for NRENs

Type of NREN:

governmental or non governmental

Funding

per year – not suitable for IRU

Multiannual – it depends…

Costs:

IRU - Per year or per period – see SEEFIRE or Porta Optica

Maintenance costs – difficult to be rightly estimated for long term period

Collocation costs – could be negotiated (usually same vendor), many times should be re-negotiated in the IRU period

Other options

There are other options instead of IRU

Building of the infrastructure

Not suitable for NRENs in most cases but could be suitable for public-private partnership

More suitable for the national/regional network, more difficult for last mile or access network

Partnership with national/regional operator

The solution adopted by RoEduNet

The Deal

Use any available fiber segment (one pair) from Telecomunicatii CFR (state owned company), install the DWDM equipment and provide in return:

at the time of installation the same number of lambdas for the NREN and for the partner

Reserve half of the DWDM channels for the partner

Cover maintenance costs for the optical equipment

Apart of the fiber pair we’ve got (provided by the partner):

Cable/fiber maintenance (max 8 hours repair time)

Hosting/collocation of the equipment

No commercial contract between the NREN and the partner – negotiations for more than 2 years (2003-2006) – not possible without political support!!

The Optical Network about 6000 km of fiber

The costs

Quite close to the calculations from SEEFIRE for equipment (5.6 MEuros incl. taxes)

4300 km of fiber in 46 segments

56 sites (ROADM: 18, ADM: 23, Amplifiers: 15)

79 lambdas installed (10 Gbps Ethernet or SDH)

Operation and maintenance:

For the fiber – done by the partner according to the agreement

For the equipment – done by RoEduNet :: contract with Felix Telecom

Operation and Maintenance

Romanian Education and Research Network - RoEduNet 9

Upgrades

The network has been extended:

From 4300 to 5600 km

From 56 sites to 69

The national backbone upgraded to 100 Gbps(six lambdas, one for each main NOC)

Conclusions

Lessons learned

Discover the underused resources (DF), push for the contribution to the education of the nation

Make a good deal and, most important, a fair one for all partners

Try to understand the needs of the partner(s) and, if possible, don’t hesitate to help, sometime you will have the service returned

Do not compete with partners of with ISPs
