UDP: the User Datagram Protocol
Quote:
Although UDP provides error checking, it does not do anything to recover from an error. Some implementations of UDP simply discard the damaged segment; others pass the damaged segment to the application with a warning.
So getting the checksum is OS and IP-stack implementation-dependent. BTW: How are you dealing with missing packets? (you are tracking sequence numbers, yes?)

jack.udp
JACK.UDP(1) JACK.UDP(1)
NAME
jack.udp - JACK UDP Transport Client
SYNOPSIS
jack.udp [options] send|recv
OPTIONS
-b : Set the ring buffer size in frames (default=4096). -c : Set the client name (default=jack.udp-PID). -n : Set the number of channels,
and therefore the number of JACK ports (default=2). -p : Set the port number (default=57160). -r : The remote host name, for use in send
mode (default="127.0.0.1").
DESCRIPTION
jack.udp is a UDP audio transport mechansim for JACK. The send mode reads signals from a set of JACK input ports and sends UDP packets to
the indicated port at the indicated host at a rate determined by the local JACK daemon. The recv mode reads incoming packets at the indi-
cated port and writes the incoming data to a set of JACK output ports at a rate that is determined by the local JACK daemon.
This transport mechanism is unreliable. Both send and recv clients will report buffer overflow and underflow occurences, and recv clients
will report dropped and out-of-order packets, and shutdown on channel mismatch packets. In practice this mechanism can be made highly reli-
able over local networks.
jack.udp implements no connection logic, use jack.plumbing(1) instead.
EXAMPLE
192.0.0.1:~$ jack.udp -r 192.0.0.2 send
192.0.0.2:~$ jack.udp recv
