Network implementation consists of the following steps:
1.Physical network design
Local Area Network design
LAN design consists of selecting appropriate devices such as Hubs,
Bridges, Switches, and Routers. Criteria for selecting LAN devices
include the following:
number of ports required at different levels
speed (10Mbps/100Mbps/1Gbps or others)
considerations, such as Ethernet, Token Ring etc.
for different network protocols such as TCP, VOIP etc.
of configuration, and maintainability
WAN technologies are available for connecting enterprise resources. A
few prominent technologies are given below:
Optical Network (SONET)
Transfer Mode (ATM)
technology that suit an enterprise requirement depends on the
bandwidth and QoS requirements, security requirements, and application
Remote Access requirements:
The companies are increasing becoming mobile.
This demands remote access capability to its executives, customers and
vendors. Devices are chosen taking into consideration the remote access
requirements of the Company. Several technologies can be used for remote
access including PPP, Multilink PPP, ISDN, or Cable Modem. Careful
consideration to be given whether the software or WAN devices support
authentication and authorization methods intended to be adopted by the
Testing, and Documentation:
Appropriate test methods be developed for
thoroughly testing a campus or enterprise network. The test methods must
include connectivity, accessibility, availability, and load testing.
Documentation is to done with the help of network diagrams. Both logical
and physical networks must be documented properly. Don't forget to take a
network baselining for future reference and troubleshooting.
