"TEST WAN"
WAN is Wide Area Network or in some areas Wireless Area Network, it is combination of several LAN's (Local Area Network). To test a WAN first of all it should be implemented carefully and properly with appropriate connections, wires and of course standards. Test WAN can be divided into 3 stages:-
1) Proper functioning of LAN with all the computers/machines communicating faithfully with each other.
2) Connecting various well established LAN's in working condition.
3) After that a WAN can be yielded out.
The testing of WAN depends on the functioning of LAN and connection of different LAN's because it is very important for a WAN that all its intermediate nodes should work accordingly.
Establishment of WAN can be done through 2 methods:-
1) Wired technique which includes implementation of wires, optical fiber cables now a days which provide higher bandwidth and less distortion in the transmitting signal and further the information can be sent to longer distances with increased quality factor and minimum BER (Bit Error Rate).
2) Wireless phenomenon in which IEEE 802.11 standard is followed. Advancements in this standard are available for better results. Access points are to be made for sending and receiving information.
Physical layer of the OSI (Open Systems Interconnection) Model is used which is responsible for the connection between sender and receiver side of the channel.
"Hello" packets can be sent or "ping" can be followed to check the connection availability at each node.
The subnetting should be done properly in order to avoid any connection lapse. Range and classes of IP's should be defined correctly and an appropriate routing protocol (IGRP, EIGRP, OSPF, RIP etc) must be implemented in accordance to the node and load requirement.
