The optical NREN of Serbia and Montenegro

Abstract

A new national backbone is in development, based predominantly on the optical infrastructure of Telekom Serbia. It will connect 19 towns in Serbia in a Gbps network by the end of 2004. The basic concept is to avoid any active components belonging to the telecom operator, by using the “nothing in line” concept. There are exceptions to that concept in cases where dark fiber was not available and in that case 1 Gbps Ethernet over SDH was used. Private CWDM of our NREN is implemented in the network for point to point n*1 Gbps channels and for making additional logical channels by using lambdas. A Web based network information system used for network monitoring, NetIS, was developed by the NREN team. It is being implemented for network monitoring, both for Serbia and Montenegro and for the SEEREN network.
