I dont know if i've understood your question properly, but i'll try and help -

is this a common protocol ? something that is implemented by vendors ? or is it something created by the people who gave it to you ?

What i would suggest you do is load the traffic into a protocol analyser.. try using IRIS, from this site. while its technically a network sniffer, it breaks down the protocol into parts.. and it recognises many protocols.

There should be a clickable link in Sahir's post, but it seems to be missing. You can get IRIS from Firewall.cx's download pages:
