Performance Settings
If you dick the question mark next to "Performance Settings," the following text will
appear in a separate dialog box:
New timing parameters have been added to allow the network manager to customize
the network to a particular operating environment. Use these settings to tailor the
network with respect to both link strength/reliability, as well as the type of network
application(s).
(Background information: In the star topology, the base station polls each CPE router
periodically, giving the routers the chance to transmit some of their queued data. The
base station must set a timeout timer, in case a response is not received from the polled
CPE router. After each CPE router is polled, the base station also has the opportunity to
transmit some queued data.)
The following parameters are used in the implementation of the polling strategy, as
described above:
• Max Frames Per BASE Timeslot
The maximum number of frames of queued data that the base will transmit
during one poll slot.
• Max Frames Per CPE Timeslot
The maximum number of frames of queued data that the CPE router will
transmit during one poll slot.
• Max Frames Per CPE Timeslot When only 1 CPE is Busy
The maximum number of frames of queued data that the CPE router will
transmit during one poll slot when only a single CPE router is considered to be
"busy." This parameter is an optimization that allows a CPE router to transmit
more queued data during a single poll slot if the network is idle. If a CPE
router is the only CPE router responding to polls with actual queued data for a
period of time, as measured by the base, it is deemed to be the only busy CPE
router in the network. In that event, this parameter will govern how much the
