Z-Stack APS data services

Other Parts Discussed in Thread: Z-STACK

HI TI Gurus,

I can find about APS layer send and receive data functionality in Z-Stack API doc:

"APS also provides data services that are not accessible to the application. Applications should send data through the AF data interface [AF_DataRequest()]."

How this data service is working is not clear to me. I know you can enable ACK for each message and define a TX window (So like TCP have reliable connection.) 

Among other management and binding functionalists, Is APS a transport layer designed and implemented on top of ZigBee networking layer so the app does not worry about packets being lost?

    Dan,
    Please consult thread : http://e2e.ti.com/support/wireless_connectivity/f/158/t/395212
    Window size in Z-Stack APS pertains to "n" number of fragments that are sent before APS Frag ACK is expected. Yes, APS (application support sub-layer ) provides an interface between the Network and the Application layer.
