LAN configuration
For Windows Vista & Windows 7 Step 1 . Click on windows key+ R key on the keyboard at the same time
Step 2 . Type ncpa in the box, then press OK
Step 3 . Select the local area connection, right click it and select Properties
Step 4 Select Internet Protocol Version 4(TCP/IPv4) , double click it or . click Properties
Step 5 There are two ways to configure the TCP/IP Properties, Assigned by DHCP . server a utomatically or manually Assigned by DHCP server. 1 Select Obtain an IP address automatically and Obtain DNS server address . automatically. If necessary, then click OK to save the settings
Assigned manually. 2 Select Use the following IP address , type IP address, subnet mask and ( 1 . default gateway IP address into it If the router’s LAN IP address is 192.168, please type in IP address 192.168 （ x is from 2 to 253 ） , subnet mask 255.255, and default
. gateway 192.
Select Use the following DNS server addresses , as shown in the ( 2 following figure. And then type the DNS server IP address, which should be . provided by your ISP. If necessary, then click OK to save the settings
. Note: In most cases, type your local area DNS server IP addresses into it The Preferred DNS server is same to default gateway. For Secondary DNS . server, you could leave it blank or type in 8.

Gateway
A gateway is a node (router) in a computer network, a key stopping point for
data on its way to or from other networks. Thanks to gateways, we are able to
communicate and send data back and forth. The Internet wouldn't be any use to
.( us without gateways (as well as a lot of other hardware and software
In a workplace, the gateway is the computer that routes traffic from a
workstation to the outside network that is serving up the Web pages. For basic
Internet connections at home, the gateway is the Internet Service Provider that
. gives you access to the entire Internet
A node is simply a physical place where the data stops for either transporting or
reading/using. (A computer or modem is a node; a computer cable isn't.) Here
: are a few node notes
· On the Internet, the node that's a stopping point can be a gateway or a
host node.
· A computer that controls the traffic your Internet Service Provider (ISP)
receives is a node.
If you have a wireless network at home that gives your entire family access to
the Internet, your gateway is the modem (or modem-router combo) your ISP
provides so you can connect to their network. On the other end, the computer
that controls all of the data traffic your Internet Service Provider (ISP) takes and
. sends out is itself a node
When a computer-server acts as a gateway, it also operates as a firewall and a
proxy server. A firewall keeps out unwanted traffic and outsiders off a private
network. A proxy server is software that "sits" between programs on your
computer that you use (such as a Web browser) and a computer server—the
computer that serves your network. The proxy server's task is to make sure the
. real server can handle your online data requests
In telecommunications, the term gateway refers to a piece of networking
: hardware that has the following meaning
· In a communications network, a network node equipped for interfacing
with another network that uses different protocols.
· A gateway may contain devices such as protocol
translators, impedance matching devices, rate converters, fault isolators, or signal translators as necessary to provide system interoperability. It also requires the establishment of mutually acceptable administrative procedures between both networks.
· A protocol translation/mapping gateway interconnects networks
with different network protocol technologies by performing the required protocol conversions.
· Loosely, a computer or computer program configured to perform the
tasks of a gateway. Gateways, also called protocol converters, can operate at any network layer. The activities of a gateway are more complex than that of the router or switch as it communicates using more than one protocol. Internet-to-orbit gateway An Internet to orbit gateway (I2O) is a machine that acts as a connector between computers or devices connected to the Internet and computer systems orbiting Earth, such as satellites or manned spacecraft. Such a connection is made when the I2O establishes a stable link between a spacecraft and a computer (or a net- work of computers) on the Internet, such links can be for control signals, audio frequency, or visible spectrum signals. Cloud gateway A cloud storage gateway is a network appliance or server which resides at the customer premises and translates cloud storage APIs such as SOAP or REST to block-based storage protocols such as iSCSI or Fibre Channel or file-based interfaces such as NFS or CIFS storage gateways enable companies to integrate private cloud storage into applications without moving the applications into a public cloud,[5] thereby simplifying data protection
NKN/NME-ICT connectivity : Introduction to NMEICT
The Cabinet Committee on Economic Affairs gave its approval for a new centrally sponsored Scheme by the name of National Mission on Education through Information and Communication Technology (ICT) submitted by the Ministry of HRD. An amount of Rs crore is to be incurred during the 11th Five Year Plan for the National Mission on Education through ICT. The National Mission on Education through ICT has been envisaged as a Centrally
work of extending 1Gbps connectivity to the universities to the nearest NKN node and Broadband VPN connectivity for the National Mission on Education Project from Ministry of HRD. In this Mission, Ministry of HRD proposed to provide 1 Gbps connectivity to 419 Universities and VPNoBB to 20000 colleges in the country for enabling them to make full use of e-contents. The scope of the NME project has finalized by Ministry of HRD is as given below. The connectivity to be provided under the National Mission for Education is : furnished below .1Gbps connectivity to universities from the nearest NKN node. 1 .Nos. of 512Kbps VPNoBB connections per College 20. 2
1GE Connectivity with NKN at four metro cities (Delhi, Mumbai, Kolkata. 3 .( and Chennai .GbPS internet bandwidth for NME network 10. 4 .Providing LAN Setup(400 nodes each) in all the Universities. 5
National Knowledge Network
The Government's decision to set up National Knowledge Network was
announced in the Budget Speech, 2008-09. An initial amount of Rs. 100 crore
for FY 2008-09 was allocated to the Department for establishing the National
Knowledge Network. A High Level Committee (HLC) was set up under the
Chairmanship of Principal Scientific Adviser to the Government of India to
. coordinate and monitor the establishment of the National Knowledge Network
Government has approved the project on Establishment of National Knowledge
Network in March, 2010 with an outlay of Rs. 5990 Cr. over a period of 10
. years. National Informatics Centre (NIC) is the implementing agency Objective
The objective of the National Knowledge Network (NKN) is to interconnect all
institutions of higher learning and research with a high speed data
communication network to facilitate knowledge sharing and collaborative
research. It will bridge the existing knowledge gap in the country. It will help
the country evolve as a Knowledge Society and spur economic activities in the
Knowledge domain. Under this Network, it is proposed that the core and
associated links to around 1500 institutions shall be established in 2-3 years
. time Application Areas The application areas envisaged under the National Knowledge Network cover · Agriculture
· Education
· Health
· e-governance
· Grid Computing (High Performance Computing)
