Starting with QUIC

[Kk Bk]

I am new to QUIC and would like get started. Require pointers for following

1) A simple QUIC client-server program, the way i would write for TCP program. 

2) Pointers to show that QUIC is way better than TCP+TLS+SPDY

Hey,

1) A simple QUIC client-server program, the way i would write for TCP program. 

There's an example QUIC client and server in the Chromium source.

Instructions for running these are here: https://www.chromium.org/quic/playing-with-quic

 

2) Pointers to show that QUIC is way better than TCP+TLS+SPDY

We recently published some performance comparisons on the Chromium blog:

Best,

Robbie

Robbie. Thanks for the pointers.

WRT QUIC client and server, can you these pointers to write my own client and server ?

Sure, if you look at the Chromium source, you'll get a pretty good idea of how to use the QUIC code in your own client/server. For example the client code here:

https://code.google.com/p/chromium/codesearch#chromium/src/net/tools/quic/quic_client.cc

The flow is something like:

1) Create a UDP socket (QuicClient::CreateUDPSocket)
2) Create a QuicClientSession and start the handshake (QuicClient::StartConnect())
3) Create a QUIC stream, and send a request to the server (QuicClient::SendRequest)

The server code is here:

https://code.google.com/p/chromium/codesearch#chromium/src/net/tools/quic/quic_simple_server.cc

and is simpler: it reads from a UDP socket, and hands off packets to a QuicDispatcher, which does all the harder work of parsing contents, creating Sessions, etc.

Does someone knows when Google is going to release a full version of QUIC server? I mean, the same version that they use in their infrastructure? 

[Ryan Hamilton]

The server the Google uses to serve production traffic is an internal server which we will not be releasing. However, that server does use the same core QUIC code that we have released.

Cheers,

Ryan

I am trying to run my own QUIC_Server and QUIC_Client ie, "ninja -C out/Debug quic_server quic_client"

Did the following to get to get started

mkdir ~/chromium && cd $_

fetch --nohooks chromium 

./build/install-build-deps.sh

gclient runhooks

Could see following directories

===============================

.gclient

.gclient_entries

src --> 0ut --> Debug

            --> Release

Ran following

=============

./build/gyp_chromium -Goutput_dir=out_cros

Finally, ninja -C out/Debug chrome

Nothing seem to happen, got stuck in following

ninja -C out/Debug chrome

log: ninja version 0.1.3 initializing

log: magic group: gid=0 (root)

log: entering main loop

log: generating initial pid array..

log: now monitoring process activity

Wondering what should i do ?

I don't believe you need to build the whole thing. I am also a newbie and this is all I did:

- checked out and installed depot_tools (explained here)

- checked out the git repo of Chromium (seems like you've already did that)

- built the binaries for quic client and server by running: ninja -C out/Debug quic_server quic_client
