More ports is still the wrong answer
ISPs should just take the cache servers Netflix offers for free and they won't need the ports because an episode of 'Orange Is The New Black" will then be shipped across the Internet backbone to their network only once instead of hundreds of thousands of times. This will help prevent the redundant copies from clogging an already burdened network and improve service for all since those redundant copies are a huge share of all background traffic now and for strict engineering purposes are entirely unnecessary. It will also improve the available quality resolutions and latency to their customers.
Level 3 wants them to add ports because they get paid to carry that redundant traffic.
