I'm working on a project where I need to communicate with a device using the transport layer. The network connection will be OSI/CLNS over IP.

I could be wrong, but I don't believe I can use sockets for this type of connection. I'm looking for examples on how to create an application that can communicate over the transport layer (either in Java or C++).

Thanks, Rob

OSI-Stack open source implementation

Here you can find open source (for linux) implementation of complete OSI stack. There is also application example there...

... create an application ...

I would say that the keyword here is application. When you talk about creating an application you automatically talk about the Application layer of the OSI 7/5 layers model. When developing an app that can communicate with another app on the network you will be using some protocols - some of them will be part of the application layer and some will be part of the transport, network, and line layer.

It's impossible to create an app-based only on the transport layer - because in order to move information along with the internet you need to have use of all the layers.

what you asking is equivalent of asking how to build a car that has ONLY wheels - no frame, no engine, no gear, no seat, no steering wheel.

I would recommend learning a little about the OSI Layers model in order to understand better this whole subject.

I would start here: https://en.wikipedia.org/wiki/OSI_model
