Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).

Treating failure as a matter of course. For example, if processing for a particular channel is taking place on a particular instance within the cluster, and that instance fails (forcing that channel role to move), mechanisms must be in place to ensure that things can continue. Fault tolerant designs treat failures as routine.

Given this higher cost for exploration, and the fact that logs for learning from are likely to explore very little of the state space, policy learning needs to be data-efficient.
