queuelat [-c|--cycles N] [-f|--freq F] [-h|--help] [-m|--max-len LEN] [-p|--packets F] [-q|--queue-len N] [-t|--timeout TIME]

queuelat simulates a network queue checking for latency violations in packet processing.

A summary of options is included below.

-c,  --cycles=N

Estimated number of cycles it takes to process one packet. This value should come from the envisioned packet forwarding application being simulated.

-f,  --freq=F

TSC frequency in MHz.

-h,  --help

Show help

-m,  --max-len=N

Maximum allowed latency, in nanoseconds. If latency to process any packet exceeds this value, the program quits, writing a message to the trace buffer.

-p,  --packets=F

Million packets per second that arrive for processing.

-q,  --queue-len=N

Minimum queue length to print in the trace

-t,  --timeout=TIME

Timeout in seconds to quit the program.
