Infrastructure

The equipment of the central telecommunication switching and routing node is installed in two rooms on the LIT second floor. The TM-301 II and TM-3000 II channel-forming devices by Infinera, two Cisco ASR1006-X edge routers and two Cisco 7606-X LAN routers are placed in the standard racks (19") in the computer room - room 219. The network core also includes three racks of network servers, a rack of JINR management databases, optical patch panels, twisted pair patch panels.

Currently, main optical data transport medium (backbone) operates at 100 Gbps. It consists of three optical rings, which are based on two network switches of the third level (L3) according to the reference network model ISO OSI (International Standard Organization Open System Interface). Three fiber optic rings cover spaced over the JINR campus - sites LNP, LHEP and "City".

Obtained rings of the optical transport backbone, which include all laboratory optical gateways, as well as central gateways JINR-GW-1 and JINR-GW-2. Central gateways aggregate all data streams and direct these streams through the border gateway JINR-GW and, if necessary, through the BACK-GW gateway to data transport structures affiliated to e-Arena and MSK-SW-1, or - from them. Partners’ task is transmitting/receiving JINR traffic and forwarding it to the destination. Means of wireless access in the JINR major divisions are to provide communication with the wired institute network are also marked on the chart.

In room 215, adjacent to room 219 there is a part of the network equipment related to the central node and network cabling structures. There are four (4) standard racks filled with active and passive network equipment. The first rack contains equipment for traffic aggregation within solution of Dubna-IX (traffic exchange node for Dubna ISPs), the second rack assembles optic patch panels, as the part of the optical backbone of the JINR local area network, in the third rack is located equipment related to the LIT LAN. Cisco 3560-E device is an element of the JINR optical backbone, as well as similar devices in other major departments of the institute.

About 80% of the buildings and housing units of the Institute are equipped with the fiber optical structures, capable to work with a speed of 10 Gbps and more. Thus, network structure of the Institute has already prepared for the fact that the fiber optic backbone will run at speed of 100 Gbps.
