Network Switch

I would use whatever you are familiar with. If devices talk to each other (vs. the roboRio), a switch would give them an independent pathway.

I don't think it would kill the entire bus. It would just isolate that portion of the network.

CAN Bus tends to be Daisy Chained, rather than connected to a common bus. So anything after that failure point would be isolated from anything before that failure point. As a multi-master serial bus, you don't have to worry about being disconnected from the Bus Master.
