NAME

6       queuelat - Queue latency test program
7

SYNOPSIS

9       queuelat  [-h]  [-m max-queue-len] [-c cycles-per-packet] [-p mpps] [-f
10       tsc-freq] [-t timeout]
11

DESCRIPTION

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

OPTIONS

18       A summary of options is included below.
19
20       -h     Show help
21
22       -m max-queue-len
23              Maximum allowed latency, in nanoseconds. If latency to process
24              any packet exceeds this value, the program quits, writing
25              a message to the trace buffer.
26
27       -c cycles-per-packet
28              Estimated number of cycles it takes to process one packet.
29              This value should come from the envisioned packet
30              forwarding application being simulated.
31
32       -p mpps
33              Million packets per second that arrive for processing.
34
35       -f tsc-freq-mhz
36              TSC frequency in MHz.
37
38       -t timeout
39              Timeout in seconds to quit the program.
40
41       -q min_queue_len_to_print_trace
42              Minimum queue length to print in the trace
