dvmcast/dvping are tools for testing the network performance for the DVTS or other UDP based high performance applications. DVTS is the system that transmits DV streams from IEEE1394 over IP. It is developed in the WIDE project.
DVTS requires 30 Mbps bandwidth for the UDP stream. dvmcast/dvping can test the end-to-end packet loss, rtt and throughput of the network without real DVTS applications, which can save a lot of debugging time both for the end users as well as network administrators.
dvmcast/dvping can support IPv4 and IPv6, unicast and multicast, ASM and SSM.
dvping is a program similar to ping. It sends a simulated DVTS stream with different throughput to dvmcast daemon and receives the reflected stream to get the round trip statistics of the network.
maketo build the executables which will be put in the bin directory.

-rp rcv_port UDP port for receiving the DVTS stream
-asm grp group address of the ASM join
-ssm src grp source address and group address of the SSM join
-sf src_flt ***
-sff sf_file ***
-ech ech_port reflection mode the sending UDP port
-d dst_addr dst_port send the DVTS stream to the destination address and port
-df dst_file save to a file
dvping [-h] [-p snd_port] [-rp rcv_port] [-t period] [-bw bandwidth] host
parameter description
-h help
-p sending port (default is 8000) [only change this value when the dvts_echo_server asks for]
-rp receiving port (default is 8000) [only change this value when the dvts_echo_server asks for]
-t time duration of each throughput (seconds)
-bw throughput (bps, k and m are allowed)
host host IP address
Additional notes for the dvping:
(1) The test throughput is start from 1Mbps, and then 2Mbps, 4Mbps, 8Mbps, 16Mbps and 32Mbps.
(2) This application can adopt the network performance, when the packet loss exceeds a threthold,
the sending throughput will not increase.
