Configuring Queues for Qualty of Service (QoS)
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.
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.
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.
