Fault Tolerant Strategies for Master Node [closed]

edit

Hello,

I am studying some communication strategies applied to distributed robots. One of topics of my study focus on detecting and handling faults on network nodes.

There is some recovering implementation for faulty nodes? If Master node gone offline, there some way to replicate and route communication messages for other nodes?

Analyzing ros_comm source code, I didn't find some related coded. There's some work on it?

Shall I consider this issue a valid point of study and implementation for ROS?

Best Regards,

Pastore
