Small Office Network Implementation

     In the diagram network divided in to two segments its uses a star topology this divided networks have connected to an intelligent hub. Intelligent hubs are connected to an Ethernet switch it will improve the performance. Following devices also have connected to this switch work station, network printer, network fax, file server, and proxy server. If all devices connect to a hub it will increase the network traffic it will slow down the network that’s the reason I used two hubs and connected to a switch.  

     Using one Network printer and one network fax reduce the cost of the network. And all the clients can capable to receive faxes instead of using one fax per computer. And all clients can use the printer as well.

     This network connects to the internet through a proxy server and the internet connection is shared to all the computers with this server. This server handles the network security not needed to use another firewall.

     The file server is used to store the documents prepared by the employees of the office.

     All the clients’ computers run Windows XP and all have Uninterrupted Power Supplies (UPS).

     Small office networks can be set up in a variety of configurations. The following factors can affect the ultimate network configuration:

  • Equipment availability and cost—in many cases, the financial support to connect a set of machines together in a network to share files, printers, and the Internet is limited. Consider the costs of acquiring and installing network adapters, hubs, other network devices such as residential gateways, and cabling.

  • Internet access availability— the network configuration can also be limited by the available options for connecting to the Internet. While standard modems and dial up access is available to nearly everyone and requires little additional investment, higher bandwidth needs might require a broadband link such as Digital Subscriber Line (DSL) or cable. Depending on the broadband provider, you might be required to use additional equipment such as a cable or DSL modem or a residential gateway.

  • Configuration simplicity— most home or small networks are not managed by an information technology (IT) department. The configuration that is eventually chosen must match the resources available to install and maintain it. With the right configuration, anyone can do this.

  • The environment of the network— whether the network is being set up in a business or home, environmental factors can affect the choices available. For example, some buildings might have restrictions on installing cabling or requirements to use existing cabling. Other locations might restrict the use of wireless network devices due to electrical shielding or interference.

  • Security for the Internet connection— The Internet connection, the physical method of connecting one or more of the computers on your internal network, must be protected from Internet attacks. This can be done using a combination of translation and firewall technologies.

  • Preferences and knowledge of installer— the network configuration is invariably influenced by the knowledge, experience, and personal preferences of the person installing the network components.
