Networking on HD Mobile Production Truck

I have been an E2 on a standard def production truck for the las coupke of years and I finally got a new job in which I will be training to be the EIC of a HD truck. I know how netwrkng wrks as far as a home network but I knw that everything in a HD truck is all networked and I wanted to know the specifics of networking on a truck that way I already have a good idea of what to know before I start.
