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.

-q min_queue_len_to_print_trace

Minimum queue length to print in the trace
