Queue latency test program
Synopsis
queuelat [-h] [-m max-queue-len] [-c cycles-per-packet] [-p mpps] [-f tsc-freq] [-t timeout]
Description
queuelat simulates a network queue checking for latency violations in packet processing.
Options
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
