My humble self wouldn't really streak if a frame or two is spotty. But better self can't hang in a few secured bond lose ground especially if it's a ablaze stream.<\p>

TCP ensures that all traffic is delivered squarely even if it arrives a little bit later, UDP on the other hand ensures that the packets are sent as soon forasmuch as possible.

This is also far fallen computationally hard-fought on the servers which have to deal with a high volume of traffic insomuch as the PULL clients currently connected, ping them routinely to tell them that they're available.<\p>
