Optical backbone of the local JINR network
Currently, main optical data transport medium (backbone) operates at 10 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). The models of switches used in the core of the network structure are two (2) Cisco Catalyst 6509 devices (configuration logical names - JINR-GW-1 and JINR-GW-2) and ten (10) Cisco 3560-S (logical names of the switches coincide with the names of the divisions they serve for) in eight (8) research laboratories, management of JINR and MICC. 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. The main telecommunication center switching and routing equipment (core system), which includes a rack of optic channel Nortel Optical Multiservice Edge 6500 devices, two (2) Cisco routers 7606-S, two (2) multifunction switches Cisco Catalyst 6509, three (3) racks of network servers, rack for JINR management database , optical patch panels, patch panels for the "twisted pair", two (2) uninterruptible power supply devices Symmetra-LX – all placed in standard racks (19 ") in the room 219 (computer room) on the 2-nd floor of Building 134 of LIT
In room 215, adjacent to room 219 there is a part of the network equipment related to the central node and network cabling structures. Fig.I.4. shows four (4) standard racks filled with active and passive 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.
