gQUIC Support & The Road to HTTP/3 | CDN77.com
gQUIC (Quick UDP Internet Connections) Protocol made by Google. It works with Chrome and was originally designed for transmission of HTTP/2 frames. It gave the incentive to standardize a new transport protocol called QUIC. This is the protocol we currently support, and which you can enable in your Control Panel.

QUIC - Wikipedia
QUIC (pronounced "quick") is a general-purpose transport layer network protocol initially designed by Jim Roskind at Google, implemented, and deployed in 2012, announced publicly in 2013 as experimentation broadened, and described at an IETF meeting. QUIC is used by more than half of all connections from the Chrome web browser to Google's servers. Microsoft Edge (a derivative of the open ...
salesforce/GQUIC_Protocol_Analyzer - GitHub
This analyzer parses GQUIC traffic in Zeek for logging and detection purposes. It examines the initial exchange between a client and server communicating over GQUIC, and extracts the information contained in the connection's client hello packet and server rejection packet. Currently, this protocol analyzer supports GQUIC versions Q039 to Q046.
wireshark - Parsing Google QUIC (GQUIC) packets that arrived at non ...
I have a PCAP file with a number of Google QUIC (GQUIC) packets. However, all of these packets arrived at UDP ports 56285 and 56046. Yet both wireshark and nDPI were able to properly parse these packets. It is my understanding that only UDP packets arriving at port 80 or 443 can be considered to be QUIC/GQUIC packets.
Google's QUIC protocol: moving the web from TCP to UDP - ttias
The really interesting bit about the QUIC protocol is the move to UDP. Now, the web is built on top of TCP for its reliability as a transmission protocol. To start a TCP connection a 3-way handshake is performed. This means additional round-trips (network packets being sent back and forth) for each starting connection which adds significant ...
What is QUIC - This new Google Protocol makes Firewalls Blind
QUIC (Quick UDP Internet Connections) is a new generation Internet protocol that speeds online web applications that are susceptible to delay, such as searching, video streaming etc., by reducing the round-trip time (RTT) needed to connect to a server. By replacing TCP with UDP and encrypting most of its payload, QUIC reduces the time it takes ...
QUIC - Wikipedia
QUIC（クイック）は、汎用のトランスポート層の通信プロトコルである。 GoogleのJim Roskindによって設計され、2012年に実装・デプロイが行われ、実験が広まっていった2013年に公表され 、その後IETFでの標準化が進められた 。 GoogleのQUICとIETFのQUICと区別して、gQUICとiQUICと呼称することもある 。
How does GQUIC affect the WebRTC process? - Stack Overflow
GQUIC seems to be a protocol built on UDP to improve latency while allowing for the reliability of TCP, and I could find no reason for it to impact on the SDP business but rather it was a coincidence that I noticed this for the first time when the other problem occured. Quick fix: change WebRTC: Use Unified Plan SDP Semantics by default to ...
QUIC - Devopedia
gQUIC's cryptographic handshake was called QUIC-Crypto. This inspired the creation of TLS 1.3 that's used by QUIC. Clients and servers can support multiple versions and negotiate the version during connection setup. Version numbers 0x00000001-0x0000ffff are reserved for the standard. gQUIC and iQUIC versions have a separate ranges.
QUIC, a multiplexed transport over UDP - Chromium
QUIC is a new multiplexed transport built on top of UDP. HTTP/3 is designed to take advantage of QUIC's features, including lack of Head-Of-Line blocking between streams. The QUIC project started as an alternative to TCP+TLS+HTTP/2, with the goal of improving user experience, particularly page load times. The QUIC working group at the IETF ...

CellStream - Using Wireshark to Analyze QUIC Traffic
I align this to the TCP SYN and SYN-ACK options in my mind. What we see is the much more complex and capable stream personality. It is from this format that I have extracted things like the maximum number of streams column and the QUIC/gQUIC version information. I hope this helps the reader get started using Wireshark and QUIC/gQUIC. Comments?

Differentiate between GQUIC and QUIC packets
There are two cases to consider: 1) GQUIC vs QUIC long-header format packet This is straightforward: the first byte in GQUIC must be zero, whereas in QUIC's long-header format packet it is set to one. 2) GQUIC vs QUIC short-header format packet Now it gets more involved.
Website fingerprinting on early QUIC traffic - ScienceDirect
GQUIC has made huge changes in design concept , packet loss recovery and congestion control mechanisms , encryption details , and flow control mechanisms to address the performance bottlenecks of TCP. GQUIC only requires userspace support, making it possible to deployed easily without changing the Internet middleware .
QUIC - HandWiki
Google QUIC (gQUIC) The protocol that was created by Google and taken to the IETF under the name QUIC (already in 2012 around QUIC version 20) is quite different from the QUIC that has continued to evolve and be refined within the IETF. The original Google QUIC was designed to be a general purpose protocol, though it was initially deployed as a ...
The Road to QUIC - The Cloudflare Blog
In the gQUIC protocol this problem was solved by simply serializing all HTTP request and response headers (but not the bodies) over the same gQUIC stream, which meant headers would get delivered in order no matter what. This is a very simple scheme that allows implementations to reuse a lot of their existing HTTP/2 code, but on the other hand ...
How HTTP/3 and QUIC Will Speed Up Your Web Browsing - How-To Geek
HTTP/3 was added to the bleeding-edge Canary version of Google Chrome in September 2019, hidden behind a command-line flag. Launching Chrome Canary with the --enable-quic --quic-version=h3-23 command-line arguments will enable HTTP/3. Mozilla announced it's working on adding HTTP/3 to an experimental version of Firefox Nightly this fall.
Employing QUIC Protocol to Optimize Uber's App Performance
In addition to improving the performance of our apps in low connectivity networks, QUIC gives us end-to-end control over the flow of packets in the user space. In this article, we share our experiences optimizing TCP performance for Uber's apps by moving to a network stack that supports the QUIC protocol.
