Where to write a interrupt handler and how to register with kernel in linux?

Scenario : Client is sending a data and the server is receving the data from client via ethernet layer (udp). When the server receives a data from the client on the ip layer (kernel). It interrupts the kernel and kernel as to execute the data by the client, so I want to create a interrupt service function to catch the interrupt from the network service card.

I can't write kernel modules (the kernel is not open) and you have real-time in user-space. However I can write code using RTLinux (real time linux) in kernel space and with kernel modules.
