Rolled Bacon is a generic term for bacon that has been rolled up into a roll.
The meat will of course be boneless, which enables it to be rolled.
In Ireland and Scotland, it is rolled so that a slice from it will have both streaky and back meat. In Scotland, it is called Ayrshire Bacon (or Ayrshire Middle Bacon.)
In Italy, a version of pancetta is a rolled bacon.
The Polish bacon called “Boczek” is a rolled bacon.
