NETWORKING
1 Introduction.
Montemurro,2012. Found that Network administration is a comprehensive process ranging from basic
physical network set up and configuration to the complexed software based administration even to
programming in the administration. Software based are those that the admins use already made
software for administration, the common software used are the CISCO based such as the WLC, WLCM
and Aeronet but they are not open source, for learning purposes, simulation software such as fiddler
and wireshark are commonly used. Network administration also extends to programming where the
admin writes programs in the provided language commonly java and python to control the network
devices in a network and the most common one is the administration using one selected node as the
admin computer by use of the command prompt for windows and for linux series, they already have
terminal interface where the admin needs to type in commands for administration.
Generally, an enterprise WLAN is made up of three basic components;
Access point:
It is the primary part for any Wi-Fi client to connect to a wired network either internet or intranet. A Wi-
Fi client scans for SSIDs broadcasted from the Access point, chooses an SSID and then connects it to the
network via standard verification process. Access point literally is that point where the server router or
server machine is placed actually the Access Point or the AP is the device itself
Authentication server(AAA):
This avails verification service to Wi-Fi clients not only by the use of user ID or password as
conservatively undertaken, but likewise by the use of user data in SIM or USIM of the smart device.
provides a network service that applications use to validate the more often, normally account names
and passwords, of their users. When a client submits a valid set of credentials, it receives a
cryptographic ticket that it can successively be used to access various services.
