The design of the physical network on site has a major impact on speed and reliability of data transmission. Most organizations now use UTP/STP/FTP and Fibre Optic structured cabling, which offer a robust and flexible solution. Each computer has a dedicated cable to the switch and can be connected or removed from the physical network without disruption.
Wireless networking offers a fast, flexible and cost effective solution for buildings where cabling is not yet in place or would be difficult to install.
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.
We at Prokom Indonesia can advise and deploy all aspects of the physical network including cabling, topology, switches and routers.
Forming the core of most commercial networks, the performance and reliability of the servers is fundamental in providing an efficient solution. When evaluating existing systems and proposing new hardware we endeavor to specify failover protection where possible by utilising RAID disk systems and redundant power supplies. We have found that deploying well specified servers at the outset offers significant benefits as the cost of upgrading older equipment tends to be relatively expensive.
Cloud file sharing portals can provide a simple alternative to conventional in-house file servers allowing data to be accessed and shared over the Internet from any location. In partnership with leading hosted solution providers, we can implement very cost effective solutions for geographically separated teams to share files with reassurance of automatic backup and virus protection.
Security is a multifaceted issue that must be addressed to avoid abuse of your network from hackers and employees. While you are connected to the Internet your network is open to the public unless it is protected by a firewall. Networks that are connected to the Internet are vulnerable to malicious attacks from hackers and virus infection. A well configured firewall will block uninvited visitors whilst allowing remote access to authorised users and services.
Networking between distributed offices allows common data resources to be shared and consolidated in a central location. Sites can be linked using leased lines or by creating a virtual private network to transfer data across the Internet. Leased lines are relatively expensive and are generally only used by larger companies. Alternatively there are an increasing range of Internet connections offering greater performance including ADSL, SDSL, VDSL and Ethernet. Secure links can be established over most types of Internet connection by using a VPN to ensure privacy. VPN utilises sophisticated encryption and encapsulation technology to allow data to be securely transmitted across the Internet. Remote workers and branch offices can establish network connections from any location using their local Internet connection. This solution can be used with standard dial-up access but is particularly effective where high speed broadband Internet connections are used.
