The random backoff used by the access point is a configurable parameter. To describe
the random delay, a “Minimum Contention Window” (MinCW) and a “Maximum Contention
Window” (MaxCW) is defined.
Packet Bursting for Better Performance
The D-Link DWL-2210AP includes 802.11e based packet bursting technology that
increases data throughput and speed of transmission over the wireless network. Packet
bursting enables the transmission of multiple packets without the extra overhead of
header information. The effect of this is to increase network speed and data throughput.
The size of packet bursts allowed (maximum burst length) is a configurable parameter.
The value specified for the Minimum Contention Window is the upper limit of a
range for the initial random backoff wait time. The number used in the random
backoff is initially a random number between 0 and the number defined for the
Minimum Contention Window.
If the first random backoff time ends before successful transmission of the data
frame, the access point increments a retry counter, and doubles the value of the
random backoff window. The value specified in the Maximum Contention Window is
the upper limit for this doubling of the random backoff. This doubling continues until
either the data frame is sent or the Maximum Contention Window size is reached.
