Need FST protocol specification

[jmartinez3]

Hello everyone,

I am involved on the developement of an analysis tool that requires knowledge on FST (Fast Sequenced Transport) protocol.

My best guess is that FST is propietary, that is why I could not find anything on the net.

But being propietary does not mean being secret. Is there anywhere I could get its definition from?

Thanks

FST uses UDP instead of TCP encapsulation. So, you would have the SNA data and a RFC-compliant DLSW header as data in a UDP packet. Nothing propietary

[jmartinez3]

I see. So FST uses no added fields to the UDP header? No sequence numbering. for example?

[tblancha]

No added fields on top of the UDP protocol. DLSW will occupy 16 bytes in the data portion of the frame and that will have some flow control inherent to it but that is RFC governed as well.

That could be why I could not find FST spec. Because there is none! :D

Thank you very much, it is crystal clear now.
