One of the things I love about the Traveller universe is the relatively slow rate of communication.
Especially as it make wargaming at scale such a tricky proposition. So many things that would normally be considered tactical or operational at most suddenly become strategic in detail - simply because of the difficulty in predicting the disposition of the opposing forces.
Even more than the age of sail, mass fleet operations feature missed opportunities more than encounters. In particular I can see frequent path crossings as forces attempt to intercept, only to end up swapping locations.
For the high command it would be like watching a video game played using RFC1149.
