[Star Wars] How do blockads work?

**Blockade**

A good example of one is in the Phantom Menace where the trade federation has a ring of Star destroyers in a ring around Naboo. First off, they're only in a single ring. A ship can literally go in any other direction. Second, even with it just being a ring I don't believe they could feasably block a ship considering the relative size of a star destroyer to a planet and it's orbit. Also, why is the blockade legal?

So far as I know there was no shield around the planet like the one in Rogue One.

Blockade was illegal, thats why they needed to capture Padme to sign a contract or something.

As to how blockades work, there are established Space Lanes that allow ships to go into Hyperspace without fear of running into something.

I guess there was only one or two ways you could leave Naboo going Hyperspeed without running into an astroids field or something, so they just blockaded those space lanes.
