Hello Douglas,

just a really fast response, we aren’t going to implement BGP over QUIC at all, at least when TLS is a required part of QUIC.

There are some thoughts about BGP 5 being encoded as CBOR and sent over something like QUIC, anyway it doesn’t make any sense to introduce QUIC to BGP now.

But reading this thread, I remembered this draft about BGP-over-QUIC. https://datatracker.ietf.org/doc/draft-retana-idr-bgp-quic/

I’m not sure what I’m going to say, but I have the impression that the session closure control method that will be chosen may have something to do with this BoQ idea.

I don’t even know if what I’m saying makes any sense or not. But if you do, it may be something that you have to take into consideration when choosing the method.

And besides, there are many other “ifs”… We don’t even know if this Draft will actually become an RFC. And if it becomes RFC, we don’t even know if it will have traction. We also don’t know if the IBRD project will adhere to this protocol, etc…

But, I thought it was opportune to mention.

Dear BIRD people,

On most systems RFC 896 TCP congestion control is used, also known as “Nagle’s algorithm”. This algorithm is intended to help coalesce consecutive small packets from userland applications (like BIRD) into a single larger TCP packet. The idea being it reduces bandwidth because there is less TCP overhead if data is bundled into fewer packets. … I think using TCP_NODELAY is interesting to consider, because it seems sensible to try to deliver BGP messages as fast as possible. OpenBGPD and FRR set the TCP_NODELAY socket option.

Hi

Yeah, i think that using TCP_NODELAY for BGP makes sense, considering there is already non-trivial framing and we write individual BGP messages with one write().
