sctptest

User-sapce SCTP (pion/sctp wrapped by go-rudp) test tool.

Features

  • Output send / receive throughput to stdout every 2 seconds
  • Select TCP for comparison
  • Select IPv4 and IPv6
  • Server/Client 1:N connections
  • Change buffer size of SCTP and UDP socket

Build

$ git clone [email protected]:enobufs/sctptest.git
$ cd sctptest
$ go build

Usage

$ ./sctptest -h
Usage of ./sctptest:
  -b <int>
    	UDP read/write buffer size (0: use default)
  -k <int>
    	Shutdown timer in seconds (0: defaults to no-shutdown)
  -l <int>
    	Port number to listen as a server (default 40916)
  -m <int>
    	Message size (default 32768)
  -n <int>
    	Number of messages to transfer (default 32768)
  -network string
    	Network type. specify "udp" for SCTP, or "tcp" for TCP (default "udp4")
  -s <string>
    	Remote server address (e.g. 127.0.0.1:40916)
  -u
    	Unordered. (UDP client only)
  -r <int>
    	Partial reliability remix value (UDP client only)
  -t <int>
    	Partial reliability lifetime value (UDP client only)

Run

Server terminal (the receiver):

$ ./sctptest -network udp4
2019/09/30 22:13:24 listening on udp:0.0.0.0:40916 ...
