Among the many problems with TCP is that the approach to reliably delivering data between machines is one-size-fits-all. But not every connection has the same needs, and some have extra information that can be used to improve reliable transport. Partly to enable innovation and customization at the transport layer (and partly to address well-understood problems with TPC), Google has created and is rolling out QUIC: Quick UDP Internet Connection. QUIC enables secure connections to be established using fewer round-trips, reducing connection latency-particularly when reconnecting to servers that have been used before. QUIC is also designed to fetch all of the multiple resources typically needed to render a web page using a single connection while avoiding the head-of-the-line that TCP would cause.
