Reusing Processes
 

The heart of an OPNET model is a process model: a state-transtion diagram with C code for each state, and rules for transition. We inherited the MAC, ARP, QUEUE and IP processes from OPNET and modified them to meet our requirement. The IGMP, RSVP and QOSIP processes on Gateway and UAPP, MAPP, RAPP, IGMP and RSVP processes on Host were developed by our Network and Simulation Lab.

Like the original processes of OPNET, our new processes are highly reusable. You could insert these processes into your node structure, for example, use your own application layer processes based on our RSVP and IGMP processes. Of course, you would need to follow the packet format we have defined.
