The number of circuits initially installed will be 97 as follows: 13 SDH64, 24 10Gbps and 60

8x1Gbps. Also 6 CWDM circuit will be installed as shown in Figure 60.

As already mentioned, about 70% of the total network will be installed until the end of 2008.

Also, in the framework of RoEduNet2 metropolitan area, DF connections will be leased for 10

years to connect the locations where DWDM/CWDM equipments will be installed to the

locations of the RoEduNet

POPs. Each NOC will be

connected

using

two

redundant metropolitan DF

segments to the premises of

partner.  It  should  be

mentioned  that  DWDM

equipments will be installed

also in each NOC.

The final topology using

DWDM (red links), CWDM

(brown links) and leased

circuit (blue dotted lines) is

presented in the Figure 61.

The presented topology is

expected to be in production

Figure 61: Final RoEduNet2 topology

until the end of 2008, the

capacity of the links depicted with dotted blue line will not exceed 100 Mbps of 1 Gbps. Within

SEELight, the project mentioned above, we plan to close the ring between DJ-MH-CS and TM

(in the south-west of country, Figure 61).

Also, within RoEduNet2 project, national level and local level connections will be separated by

using the new national communication node installed in the premises of the National Authority

for Scientific Research. The new data center will operate all international connections and the

connections to regional NOCs. In this framework in Bucharest there will be two NOCs; the new

national NOC and the old NOC in Bucharest that will provide services for the south-eastern part

of the country.

The modernization of the data centers in Iasi, Cluj Napoca and Timisoara is planned for 2008; the

goal is to provide reliable communication services for the research and academic communities in

Romania and to be able to provide 24 by 7 operation and support.

International connectivity:

The connection of the Romanian NREN to the GEANT network is congested since September

2007 and the capacity of the link requires immediate upgrade. As mentioned in the previous

chapter, 10 Gbps link has been requested from DANTE since the beginning of 2007, also upgrade

of the DWS service to at least 1 Gbps has been requested at the same time. The upgrade to

10Gbps will be available starting with Q2 2008 according to DANTE, but due to the critical

situation a new STM circuit will be installed hopefully until the end of January 2008.

There are two main options to have RoEduNet connected to GEANT using either lambda services

or DF. The first approach was to install DF from Budapest to Athens through Bucharest and Sofia

within GN2 project. The second approach was to finish the SEELight project. The last plan is to
