I hope this is the right place to ask. Is quic supported on relay-v2, and if not, what are the future plans regarding this? |
@geotro yes it is supported. You can combine them in the same manner as it is done here with tcp and quic: rust-libp2p/transports/quic/tests/smoke.rs Lines 118 to 136 in a714864
and either replace the Does this help? |

@elenaf9 it helps a bit, but I was hoping that once QUIC is implemented to be able to do UDP, as well as DCUTR. Why are you referring to TCP in the context of QUIC? I understand DCUTR with QUIC is not yet supported so I'll have to wait until that works before I retry it. |
I was referring to TCP to point out how you could support both TCP and QUIC together with the relay-v2 protocol. But TCP is not required, you may as well just combine QUIC and relay-v2. |
Ah OK, thank you for clarifying this! My use case requires DCUTR so I'm going to have to wait until this is available together with QUIC before I can begin testing/using it. Very much looking forward to this as I hope it's going to greatly improve the success rates of establishing a direct connection! |
Notes: - This is only compatible with v1 so likelihood of connecting to go-libp2p and go-ipfs/kubo peers via quic will unlikely to work until draft-29 is supported in rust-libp2p (see libp2p/rust-libp2p#3133) - DCuTR will not work with quic-v1 at this time so unless port mapping/UPNP is used (coming later), we wont be able to utilize quic-v1 with hole punching, but should work fine with relay (see libp2p/rust-libp2p#2883) Closes #10
Is there an issue or note somewhere what is missing for a working setup with QUIC + DCUTR + relay v2? Looking what pieces are missing there and would love any pointers. |
As far as I remember, the only thing missing is the implementation of rust-libp2p/transports/quic/src/transport.rs Lines 182 to 191 in 56b3b8f
Note that https://github.com/libp2p/punchr/blob/main/rust-client/ is already using QUIC for hole punching, though only on the @Frando contributions here are welcome. |

Thanks for compiling this list @mxinden! This looks pretty comprehensive. Some thoughts:
|
The way it is implemented in #3964 is through channels sending quinn_proto::Transmit. However the go impl uses multiple sockets with SO_REUSEPORT. So in quinn wrapper we can go both ways not sure which one is better. |
Implement `Transport::dial_as_listener` for QUIC as specified by the [DCUtR spec](https://github.com/libp2p/specs/blob/master/relay/DCUtR.md). To facilitate hole punching in QUIC, one side needs to send random UDP packets to establish a mapping in the routing table of the NAT device. If successful, our listener will emit a new inbound connection. This connection needs to then be sent to the dialing task. We achieve this by storing a `HashMap` of hole punch attempts indexed by the remote's `SocketAddr`. A matching incoming connection is then sent via a oneshot channel to the dialing task which continues with upgrading the connection. Related #2883. Pull-Request: #3964.
It appears that the above description of this issue is rather outdated, do you mind updating it? |
Status Update We just released |
I am closing here as the major milestone, adding QUIC to rust-libp2p, is achieved. Smaller follow-up improvements are tracked in individual issues. Thank you to the many many many people involved in this effort. ❤️ |
