Methodology
Non-intrusive, in-band
Virtual Circuit (VC) Traffic
Group Measurements: % bandwidth
utilization, kbps, delays, VC status
(24 hour)
Detail: Frames, octets, kbps, delay
measurements, VC status
VC Status
Up, down, BECN set, FECN set, DE set,
bandwidth utilization threshold exceeded,
delay threshold exceeded
VC Traffic Detail Measurement Intervals
Current/previous second; cur/prev 15
min; cur/prev 2 hour; cur 24 hour;
previous 7 complete days, 12 2-hour
intervals for current day
VC Delay Measurements
Maximum observed delay, average delay,
attempts made, measurement packets
lost Automatic delay measurements for
up to 64 active VCs
VC Delay Diagnostics
Round-trip VC delay via in-band
Frame Relay Performance Thresholds
User configurable
Access bandwidth utilization
Round-trip delay
