Agenda  IRU and DF IRU  NRENs and IRU  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 Thank you - Questions
