<strong>COMNET</strong> <strong>III</strong> Reports and Statistics<br />
1.7 Aloha, CMSA, CMSA/CA, CMSA/CD and C.A.N. Link Monitors<br />
The contention channel is the primary channel for data communications on the link.<br />
Statistics for the control channel transmission delay are only gathered when the control<br />
channel has been enabled on the Link Specifics tab, and a Control Node has been specified.<br />
The control channel allows the non control nodes attached to the link to respond to control<br />
node messages along a contention free channel.<br />
Contention Channel Utilization<br />
Control Channel Utilization<br />
Measure the percent of capacity at which the contention channel of the<br />
link is utilized.<br />
Measure the percent of capacity at which the control channel of the link<br />
is utilized.<br />
Contention Channel Transmission Delay<br />
Control Channel Transmission Delay<br />
Deferral Delay<br />
Deferral Queue Size<br />
Multiple Collision Episodes<br />
Collisions Per Collided Frame<br />
Contention Channel Frame Size<br />
Control Channel Frame Size<br />
Measure the link layer frame delay of the contention channel.<br />
Measure the link layer frame delay of the control channel.<br />
Measure the delay time of a link layer frame to transmit when the frame<br />
detects that the link is busy and "defers" transmission until the link is<br />
idle. This measure only applies to the contention channel.<br />
Measure the queue size of link layer frames that have deferred<br />
transmission until a busy link becomes idle. This measure only applies<br />
to the contention channel.<br />
Measure the number of times that two or more link layer frames collided.<br />
Measure the number of link layer frames that collided per collision episode.<br />
Measure the size of the link layer frames being transmitted across the<br />
contention channel.<br />
This monitor measures the size of the link layer frames being transmitted<br />
across the control channel.<br />
