The company BitTorrent, in charge of protocol of the same name, announced a major change in the latter. Indeed, instead of relying on TCP, the next version of the protocol should use the UDP. A major change resulting from ads cataclysm and end of the world.
An article in particular has literally set fire to the powder. Written by Richard Bennett on The Register, he announced that this change in BitTorrent protocol will cause an Internet overload to the point where it could collapse. Why? Because the mass represented by P2P networks represent 50% of the volume of data in transit in the network of networks.
The end of congestion control?
There are fundamental differences between TCP and UDP, although the two are used for data transfers over the Internet. TCP, its name Transfer Control Protocol, which controls the information sent via the Internet Protocol (IP). The User Datagram Protocol meanwhile does not control and is most often used when small amounts of data must be transferred as soon as possible. There is no flow control or no control congestion.
And it is this last point that worries both Richard Bennett. Without any congestion control, the flow will go bitorrent force. In addition, the UDP has a very low tolerance for delays, hence its use in many VoIP solutions. As a result, Bennett described the next version of the protocol as "aggressive" and "uncontrollable".
