POS-3504As Module
142 SmartBits System Reference
•
Generates up to 256 independent IP streams (peer-to-peer) and analyzes up to 64K
streams at any given time.
•
Instruments a nearly unlimited number of flows per stream, thereby stressing a router
by having to perform a different routing decision for each and every frame.
•
Per-stream protocol and frame size (40 to 16K bytes) settings and per-port
transmission mode control settings (continuous, single-burst, multi-burst, continuous
multi-burst, echo).
•
Arbitrary stream sequencing enables mixing of various frame rates.
•
Real-life traffic shaping through random frame length, inter-frame gap, and frame
content settings.
•
Unicast, broadcast, and multi-cast traffic effects may be analyzed.
•
16MB capture buffer enables logging and exporting of filtered events to external
protocol analysis equipment.
•
Per-port statistics provide counters for transmitted frames, received frames, received
bytes, and received CRC errors.
•
Full SmartMetrics testing capabilities:
– Sequence Tracking.
– Latency over Time.
– Latency per Stream.
– Latency Variation.
– Raw Tags.
•
Additional analysis capabilities include data integrity checking of payload and IP
header checksum verification.
