queuelat - Queue latency test program
queuelat [-h] [-m max-queue-len] [-c
cycles-per-packet] [-p mpps] [-f tsc-freq] [-t
timeout]
queuelat simulates a network queue checking for latency violations
in packet processing.
A summary of options is included below.
- -h
- Show help
- -m max-queue-len
- Maximum allowed latency, in nanoseconds. If latency to process
any packet exceeds this value, the program quits, writing
a message to the trace buffer.
- -c cycles-per-packet
- Estimated number of cycles it takes to process one packet.
This value should come from the envisioned packet
forwarding application being simulated.
- -p mpps
- Million packets per second that arrive for processing.
- -f tsc-freq-mhz
- TSC frequency in MHz.
- -t timeout
- Timeout in seconds to quit the program.
