Network Architecture IEEE 802.11

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.

1. Basic Service Set (BSS)





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:




2. Independent Basic Service Set (IBSS)





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.



3. 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 :


1. Extended Service Set (ESS) by using cable to Distributed System



Traffic flow to operate for Extended Service Set (ESS) by using cable to Distributed System is the following :





2. Extended Service Set (ESS) by using wireless to Distributed System



Traffic Flow to operate for Extended Service Set (ESS) by using wireless for Distributed System is the following:
