These are servers that come with the base server framework release. They consist of a selection of example UDP servers that demonstrate various designs for UDP servers including connection oriented servers.
These examples require the core server framework libraries (see here
for licensing options). You can always download the latest version of these examples from here
; and although you will need the correct libraries to be able to build them you can look at the code and see how it works and perhaps get ideas from it. Compiled, unicode release, builds of the examples are available on request if you require them for performance analysis of the framework.
