A new protocol dissector for PICMG SFP.0 and SFP.1 I-TDM. This dissector will
only dissect the so-called 125usec modality of I-TDM currently. I-TDM
(Internal TDM) is a protocol used to encapsulate voice traffic into ethernet
frames and vise-versa. The protocol is not based upon IP/UDP/TDP, but is a
totally new protocol which uses MPLS. One problem with it is that it does not
have a convenient way to automatically identify the frames as being I-TDM, so
what I did was just choose a magic MPLS tag value (0x99887 in this case) which
the itdm dissector registers with the MPLS dissector. This "magic tag" value
can be changed by the user in the I-TDM options panel. This should not be too
much of a problem (hopefully!) as I-TDM is specifically designed for use only
within a cabinet (a ATCA rack for example) and solely on it's own network.
It's not designed or intended to be used over an arbitrary network such as the
internet.
I have tested this dissector on Linux (SuSE 10.2 under KDE), but I don't have a
machine to test this on Windows.
Please have a look at it and let me know what you think. For me at least it is
very useful...
thanks,
dan
