How to use QUIC without HTTP/SPDY semantics

[Henning Böger]

Hi,

we would like to use QUIC as a raw transport protocol for a different application protocol (CoAP).

We are currently struggling to use QUIC without the HTTP / SPDY semantics.

What we basically need:

• Initiate connection (client)
• Listen for incoming connections (server)
• Send raw application data (both client and server)
• Receive raw application data (both client and server)

We have already looked into /src/net/quic and /src/tools/quic (the test client/server), as well as /src/components/cronet.

We also tried using https://github.com/devsisters/libquic and http://devsisters.github.io/goquic/.

However, all these clients/servers use the HTTP/SPDY semantics, and we found it hard to separate the raw data transport.

We would really appreciate any help / pointers in the right direction how to get to a raw data transport with QUIC.

Thanks!

You'll need a custom session and stream class. Check out the files in net/quic/p2p as a guide.

Thank you! We will give it a try.

I see that there are a number of initiatives in this direction , please see the previous post on this matter 

https://groups.google.com/a/chromium.org/forum/#!topic/proto-quic/2W15aduTNsA 

I am a co-supervisor of this project, and the latest news is that the students managed to send raw data from one peer to the other. I'll ask the students to chime in as they have the details

Thanks! We are currently working with the p2p code and making modest progress. Seems like this is the best way to go for the moment.

Hi Ingemar,

I'm looking at doing something similiar with QUIC (not using http/spdy). Did you and your students have any success with this ?

Thanks,

Hello, I cannot find the "net/quic/p2p" directory that was referred earlier in this post. Has it been moved to somewhere else ?

Here is the link to "net/quic", there is no "p2p":
https://github.com/google/proto-quic/tree/master/src/net/quic

[Shawyoun Shaidani]

Are there any updates for this? I couldn't find the P2P code. Basically, I have a TCP based application that I want to migrate to QUIC, and I have no idea how to change the Chromium source code to do so. The only other example I have seen is Mario L's paper, but I'm not sure how applicable that code will be. He's posted in this community before but I don't know how to "tag" him here.

[Dmitry Sobinov]

You can probably check this class and all the related stuff in the quarts directory:

https://cs.chromium.org/chromium/src/net/quic/quartc/quartc_session_interface.h

Original p2p code is indeed missing.

Regards,

Dmitry

Hello Showyoun:

I have found the code for the p2p directory in an older commit of the chromium source. At the top level src directory do:

git checkout 6581bb3e791018e48d078a910ddfdce19a1c10bb

However, because of the lack of documentation I still don't know how to use the QuickP2Psession.

It would be super useful if there is a simple client and server example that uses them. We are also trying to have a TCP based application to use QUIC instead. The sample client and server that comes with Quic is all glued to SPDY and HTTP.

Could you post where we can find the paper by Mario L. That would be very useful.

Thanks

i check the lastest version of proto quic, there is a directory named quartc, not sure what is it? is it a p2p quic source code?

Yes, it's the base of a p2p implementation of WebRTC over QUIC.

there are neither simple client nor server example for the quartc, i just find the unittest that simulating the socket transport, 

are there an implementation of the quartc client and server?

have you successfully to build p2p client and server examples?

i'v already successfully removed the spdy semantics from quic.

Hi,

[Max Demers]

Any tips for removing spdy semantics? I am still working to make my own client/server tests separate from the provided ones. Did you use the quartc to help guide you?

[howard liao]

try use quartc

 hello Sobinov,

 what is the abbreviation of quartc?

Hi

I also like to use QUIC streams as a "raw socket", are there any new examples? It seems the mentioned examples from p2p and quartc are no longer available and it is still very hard to separate SPDY/HTTP3 from the chromium/quiche sources.

Any feedback is appreciated.

Ralf

[Tony Peters]

Yes I would like to use quic in p2p  environment
