Logos XT is a networking middle-layer maintained by the LabVIEW Network Technologies and Security group. Logos XT provides a thin layer on top of TCP/IP to simplify some common network tasks.
The underlying foundation for NI networking is called Logos.
I believe that the basic idea is Logos is what is going on behind the scenes at the base level and Logos XT lets you build your own networking protocols on top of Logos. Logos XT would be used if you want to make your own networking protocol instead of using TCP/IP or UDP.
