UDP Checksum
You can enable the UDP checksum in the RTP stack.
A checksum is a count of the number of bits in a transmission unit that is included with the unit so that the
receiver can check to see whether or not the same number of bits arrived. If the counts match, it is assumed
that the complete transmission was received.
UDP checksumming is disabled by default to gain performance. In this case, the UDP checksum is not
calculated. The value 0 is written in the
checksum
field of each RTP packet header.
This feature is currently located under the
mediatrixExperimental
branch of the MIB structure. See
for more details.
To enable UDP checkum:
1.
In the
sipExperimentalMIB
, set the
sipRtpUdpChecksumEnable
variable to
enable
.
The UDP checksum is calculated for each RTP packet. Note that this may affect performance. The
parameter takes effect on the next connection.
