After knowing architecture from protocol 802.11, we also need to
comprehend standard of network architecture 802.11, released by IEEE.
Before feebleness solution and make-up of security protocol 802.11.
- Basic Service Set (BSS)
- Independent Basic Service Set (IBSS)
- Extended Service Set (ESS) Extended Service Set (ESS) consisted of some Basic Service Set (BSS) what each other overlap and each having Access-Point. Access-Point one another attributed to by Distributed System (Ds). Distributed System (Ds) can in the form of cable and or wireless. So there is 2 kinds of Extended Service Set (ESS) such as at picture in the following is :
- Extended Service Set (ESS) by using cable to Distributed System
- Extended Service Set (ESS) by using wireless to Distributed System
Configuration
BSS minimize there are a Access-Point which in circuit to network of
cable or internet. This Access-Point recognized also as managed
network. Communication of among two stations, for example A and B, have
to from station A to Former Access-Point later then Access-Point
repeat to send data to B. To develop build a network with server of at
this configuration, server placed at Access-Point and Other stations as
client.
Traffic Flow to operate for Basic Service Set (BSS) is the following:
Configuration
of Independent Basic Service Set (IBSS) known as by an independent
configuration. Logically configuration IBSS loo like with network of
cable peer-to-peer, where communications usher station earn conducted
directly without existence of managed network. This type IBSS
recognized also as ad-hoc network and generally for network wireless in
finite by space and is not interfaced to by network of computer or
broader internet.
Traffic flow to operate for Extended Service Set (ESS) by using cable to Distributed System is the following :
