Our Services - Networking

Share & Cut Costs:

We can help you to setup a office or home network, where you can share computer resources like internet connection, printers, scanners, fax machine and files, to all the computers, which are inter connected with one another.
You also need computer networking, in case you are running any network based software, a good network design can not only help you to cut IT expenses but also helps you to save time and increase the overall capability and productivity of your business.

 

Networking Devices

Network Interface Card - Also known as LAN Card, this card is installed inside your computer motherboard.
Hub- A network hub or repeater hub is a device for connecting multiple twisted pair or fiber optic Ethernet devices together, making them act as a single network segment.
Switch - A switch is a computer inter-connecting device similar to HUB, but the design of a Switch compared to a HUB is more advanced, and it can support transfer speeds up to 10 Giga Bits.
Router - A Routers connect two or more logical subnets, which do not necessarily map one-to-one to the physical interfaces of the router.
Wifi Router - A wireless router is a network device that performs the functions of a router but also includes the functions of a wireless access point. It is commonly used to allow access to the Internet or a computer network without the need for a cabled connection. It can function in a wired LAN (local area network), a wireless only LAN, or a mixed wired/wireless network.

AIPL - Local Area Networking

A local area network (LAN) is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building using network media.[1] The defining characteristics of LANs, in contrast to wide area networks (WANs), include their usually higher data-transfer rates, smaller geographic area, and lack of a need for leased telecommunication lines.
LANs may have connections with other LANs via leased lines, leased services, or by tunnelling across the Internet using virtual private network technologies. Depending on how the connections are established and secured in a LAN, and the distance involved, a LAN may also be classified as a metropolitan area network (MAN) or a wide area network (WAN).

AIPL - Wireless Networking

A wireless local area network (WLAN) links two or more devices using some wireless distribution method (typically spread-spectrum or OFDM radio), and usually providing a connection through an access point to the wider internet. This gives users the mobility to move around within a local coverage area and still be connected to the network.
Wireless LANs have become popular in the home due to ease of installation, and in commercial complexes offering wireless access to their customers; often for free. Large wireless network projects are being put up in many major cities.

AIPL - Wide Area Networking

A Wide Area Network (WAN) is a telecommunication network that covers a broad area (i.e., any network that links across metropolitan, regional, or national boundaries). Business and government entities utilize WANs to relay data among employees, clients, buyers, and suppliers from various geographical locations. In essence this mode of telecommunication allows a business to effectively carry out its daily function regardless of location.
Geographical Location
WAN is a computer network spanning regions, countries, or even the world. However, in terms of the application of computer networking protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different LANs, MANs and other localised computer networking architectures. This distinction stems from the fact that common LAN technologies operating at Layer 1/2 (such as the forms of Ethernet or Wifi) are often geared towards physically localised networks, and thus cannot transmit data over tens, hundreds or even thousands of miles or kilometres.
WAN Purpose
WANs are often built using leased lines. At each end of the leased line, a router connects the LAN on one side with a second router within the LAN on the other. Leased lines can be very expensive. Instead of using leased lines, WANs can also be built using less costly circuit switching or packet switching methods. Network protocols including TCP/IP deliver transport and addressing functions.
WAN Utility
WANs are used to connect LANs and other types of networks together, so that users and computers in one location can communicate with users and computers in other locations. Many WANs are built for one particular organization and are private. Others, built by Internet service providers, provide connections from an organization's LAN to the Internet.

AIPL - Virtual Private Networking

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or individual users with secure access to their organization's network.
VPN aims to avoid an expensive system of owned or leased lines that can only be used by one organization. The goal of a VPN is to provide the organization with the same, secure capabilities, but at a much lower cost.
Virtual Private Networks reduce network costs because they avoid a need for many leased lines that individually connect to the Internet. Users can exchange private data securely, making the expensive leased lines redundant.
VPN in Mobile
Mobile VPNs handle the special circumstances when an endpoint of the VPN is not fixed to a single IP address, but instead roams across various networks such as data networks from cellular carriers or between multiple Wi-Fi access points.
Mobile VPNs have been widely used in public safety, where they give law enforcement officers access to mission-critical applications, such as computer-assisted dispatch and criminal databases, as they travel between different subnets of a mobile network.[15] They are also used in field service management and by healthcare organizations, among other industries.
Security in VPN
Secure VPNs use cryptographic tunnelling protocols to provide confidentiality by blocking intercepts and packet sniffing, allowing sender authentication to block identity spoofing, and provide message integrity by preventing message alteration.
Secure VPN protocols include the following:
• IPsec (Internet Protocol Security)
• Transport Layer Security (SSL/TLS)
• Datagram Transport Layer Security (DTLS)
• Microsoft's Microsoft Point-to-Point Encryption (MPPE)
• Microsoft introduced Secure Socket Tunnelling Protocol (SSTP)
• MPVPN (Multi Path Virtual Private Network),
• Secure Shell (SSH) VPN
