Reserving Line Resources
114064 Rev. B 6-11
By default, the threshold is set to 0; the Resource Manager uses the simple first-fit
algorithm. If you select a value greater than 0, the Resource Manager still uses the
first available line with reservable bandwidth to service requests, but moves to the
next available line after reaching the configured threshold. When all lines are at
their threshold, the Resource Manager resumes using the simple first-fit
algorithm.
Set this parameter only if you have configured the Resource Manager on a
multiline circuit and have set the Multiline Select Algorithm parameter to First
Fit.
Setting the Reservation Latency
By default, the maximum latency for a reserved flow packet is 50 milliseconds,
limiting the amount of unreserved data that the link scheduler can transmit. When
the data transmit ring reaches a size where the time to transmit the data is greater
than the value of this parameter, no more unreserved data will be queued.
You can set the reservation latency from 0 to 214748364 milliseconds. Reduce the
value of this parameter to obtain better delay characteristics for reserved flows,
but note that overall throughput may decrease. Increase the default value to
improve throughput, but note that reserved-flow delays may increase.
