1. No, the channel protocol can use ssh but doesn't have to, the transport layer is further down in the stack. The actual execution of the command is performed on the agent/slave bu the slave.jar process and the request to do so is a command sent over the remoting channel from the master, what you see on line 95 [1] is a helper method to sent that command to the slave.jar process on the agent.
