HTTP 2

HTTP/2 (originally named HTTP/2.0) is the second major version of the HTTP network protocol used by the World Wide Web. It is based on SPDY. HTTP/2 was developed by the Hypertext Transfer Protocol working group (httpbis, where bis means "repeat" or "twice") of the Internet Engineering Task Force.

SPDY

SPDY (pronounced speedy) is an open networking protocol developed primarily at Google for transporting web content. SPDY manipulates HTTP traffic, with particular goals of reducing web page load latency and improving web security. SPDY achieves reduced latency through compression, multiplexing, and prioritization, although this depends on a combination of network and website deployment conditions.
