2. Agenda IRU and DF IRU NRENs and IRU Options to get the DF
RoEduNet case
The deal
Costs
6 year of operation

3. 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

4. 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

5. 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

6. 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 ( ) – not possible without political support!!

7. The Optical Network about 6000 km of fiber

8. 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

9. Operation and Maintenance
Romanian Education and Research Network - RoEduNet

10. 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)

11. Conclusions Lessons learned Thank you - Questions
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
