receive a UDP packet

Hi,
I would like to receive a special * UDP packet. It is measured following structure:

The data lengths are known. I would work with "DatagramPacket.
My question is: how can I teach mango which he lists the contents of the I / O and I can assign each bit points?
Is there an educational requirement for the datasource packages?

* The package was created in C (memcpy) and sent via broadcast.

This can be done, but it does involve an educational investment. The SMNP driver uses UDP, as does BACnet, but the listening and parsing code is wrapped up in the libraries. Still, if you know Java, it shouldn't be too hard to do.

that's the problem, my java knowledge is limited ^ ^
