1 edit | Necessary step; cable still has upload limitations Given that cable technology and available equipment still has upload limits that are lower than download limits( »computer.howstuffworks.com/question589.htm ), cable companies still have to manage how much uploading takes place in an area so as to not degrade the performance of the several hundred to several thousand users that share a node.
Since some P2P default configurations put no limit on how much uploading takes place, cable companies are looking for hardware and software that can throttle, but not terminate, applications that could saturate the upload capacity of a node.
While heavy users of P2P apps like bit torrent won't like these limitations, it is a better solution than just closing off ports or finding other ways to totally block an application. Using a scalpel instead of a sledge hammer.
Some will say that cable should have upstream speeds as fast as download. But that would involve a massive increase in the number of CMTS ports and an equivalent increase in equipment costs. The cost increases would just be passed on to all of a cable companies customers, all in the attempt to satisfy less than 5 % of their user base.
It would be better if the P2P apps would ship with defaults that limits the upload characteristics of product.

| Re: Necessary step; cable still has upload limitat Well said - cable at the end of the day is a shared technology, and users do not understand the cost to upgrade facilities.
Residential users just don't understand what it costs to provide bandwidth to them. If every user could have 5 megabits of upload available 24/7/365, it would cost hundreds of dollars a month. Oh wait. Verizon charges ~$200/month for that service.
