Networking

The design of the physical network has a major impact on speed and reliability of data transmission.

Most organisations now use Cat 5e structured cabling which offers a robust and flexible solution. Each computer has a dedicated cable to the switch/hub and can be connected or removed from the physical network without disruption.

Replacing old hubs with inexpensive switches greatly enhances the speed of data transmission by creating dedicated connections between the source and destination. Gigabit Ethernet switches and adapters are now available at a relatively modest cost and, used as a backbone, provide an excellent means of reducing bottlenecks to the servers.

CNSI can advise and deploy all aspects of the physical network including cabling, topology, switches and routers.

The Internet

The Internet has become an invaluable communications media, data resource and distribution channel for businesses.

There is a wide range of increasingly fast internet connection options for both offices and home workers such as ADSL, SDSL, Wireless DSL and cable. Mobile workers can now connect to the Internet with a variety of laptop and hand held devices through GPRS/3G to connect to the office and maintain e-mail communication.

Branch offices, home and mobile users can securely connect across the Internet to corporate networks and share central data using securely using VPN (virtual private networking) creating cost effective wide area networking solutions.

CNSI can advise on the most appropriate Internet connection options, arrange provisioning and deploy the necessary routers and firewalls to deliver fast access, security for the local network and remote access.
