About the Division

Server Room

Information Technology Cell Introduction The Information Technology (IT) Cell was created in the Institute in February 2001. The roll of the IT cell is to provide/maintain network (LAN and WAN) facilities and to strengthen the computer activities with latest facilities in the Institute by procuring the necessary Hardware and Software. The cell is also responsible for arranging training to the Officers/Scientists/Staff members of the Institute whenever it is required. Following facilities are being provided by the IT cell.

Local Area Network (LAN)
IWST has established Local Area Network (LAN) at its campus in December 2000. A high speed 100mbps Switched Ethernet fibre backbone is used. The LAN at the Institute is distributed in two Office/laboratory buildings with one fibre optic backbone. Three switches and one hub have been used for the entire networking. Three servers, visible to the outside world, are connected to the backbone switch which in turn is connected to the router. Backbone switch is connected to access switch at different building via six-core multimode fibre optic cable. The UTP Enhanced CAT-5 cable connects the nodes to the working switches and hubs. There are around 100 nodes spread all over the campus.

Wide Area Network (WAN)
A virtual private network (VPN) at IWST campus is currently being provided by ICFRE through Bharath Sanchar Nigam Limited (BSNL) as an Internet Service Provider (ISP). The bandwidth currently available is 2 mpbs. The Web Site of the Institute, globally accessible on http://iwst.icfre.gov.in is developed, hosted and maintained by the IT Cell.

A virtual private network (VPN) is a computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network. The link-layer protocols of the virtual network are said to be tunneled through the larger network when this is the case. One common application is secure communications through the public Internet, but a VPN need not have explicit security features, such as authentication or content encryption. A VPN may have best-effort performance, or may have a defined service level agreement (SLA) between the VPN customer and the VPN service provider. Generally, a VPN has a topology more complex than point-to-point. The distinguishing characteristics of VPNs are not security or performance, but that they overlay other network(s) to provide a certain functionality that is meaningful to a user community.
