    Google gooses Chrome with network speed-boost idea: 'QUIC' | Internet & Media - CNET News (click for full article)

    by Stephen Shankland - June 27, 2013

    Summary:
    Trying to cut Net communication delays, Google has begun testing a new technology called QUIC that seeks to marry security, reliability, and performance.


    -- "On the heels of its SPDY success for goosing Web communications standards, Google is tinkering with an even lower-level protocol with a project called QUIC.

    To see if the technology meets its potential without causing new problems, Google has built QUIC into developer versions of Chrome and enabled it for a fraction of users. The hope is that it will cut the round-trip time of the back-and-forth communications between computers on the Internet, according to Google engineer Jim Roskind on a blog post Thursday."

    Google Adds Its QUIC Network Protocol to Latest Chrome Build (click for full article)

    by Emil Protalinski - June 27, 2013

    "Google today took the wraps off a new experimental protocol called Quick UDP Internet Connections (QUIC) and added it to Chrome Canary, the latest version of its browser. QUIC includes a variety of new features, but the main point is that it runs a stream multiplexing protocol on top of UDP instead of TCP.


    Google says it has been working on both a QUIC client implementation and prototype server implementation for the past few months. While early tests of UDP connectivity have been promising, the company says it has learned from past experience "that real-world network conditions often differ considerably."


    As such, Google is looking to test the pros and cons of the QUIC design in the real world by experimenting with it for a small percentage of Chrome canary and dev channel traffic to some Google servers. "Users shouldn't notice any difference-except hopefully a faster load time," the company says.


    Here are the QUIC highlights Google wants to emphasize right now:


    - High security similar to TLS.
    - Fast (often 0-RTT) connectivity similar to TLS Snapstart combined with TCP Fast Open.
    - Packet pacing to reduce packet loss.
    - Packet error correction to reduce retransmission latency.
    - UDP transport to avoid TCP head-of-line blocking.
    - A connection identifier to reduce reconnections for mobile clients.
    - A pluggable congestion control mechanism.


    In other words, QUIC is yet another protocol that Google is building to help speed up the Web."
