Actually it's not so important. I forgot about qlog and qvis.
The real question I wanted to ask is why STREAM_DATA_BLOCKED
frame is sent so early.
Here are my qlog files (I had to rename them to .txt
as github doesn't accept .qlog
)
Server sets flow control to 7000B while client tries to send more than that.
What I can't understand is that client sends STREAM_DATA_BLOCKED
frame so early, before reaching flow control limit.
It looks like this
In the first packet after establishing connection (1 RTT: 0
) there are different frames. One of them is STREAM_DATA_BLOCKED
. I can't get why server receives it so early. Shouldn't he receive it in 1 RTT: 6
packet?
To answer your original question, Wireshark should definitely be able to decode QUIC v1 packets, though you might need a recent version (according to https://github.com/quicwg/base-drafts/wiki/Tools#wireshark you need at least v3.4.x).
As for the STREAM_DATA_BLOCKED
thing, it does indeed look weird, Are you using a custom client/server or the apps we provide (https://github.com/cloudflare/quiche/tree/master/tools/apps)? If the latter, it would be useful if you could provide the trace logs (just need to run the programs with the RUST_LOG=trace
environment variable set).

Thanks, good point with Wireshark's version. Acctually I have 3.4.0rc1 but I will try with a newer one.

I am using client and server from https://github.com/cloudflare/quiche/tree/master/examples but IIRC apps from tools use them too?
I have modified them a little to exceed flow control limit but these modifications were quite simple. I will put trace logs as soon as possible
Hi, is it possible to decode QUIC v1 in Wireshark? I can do this with ID-29 (quiche 0.7.0) but after switching to v1 (quiche 0.9.0) decoding packets in Wireshark is no longer possible. I suppose that this is rather Wireshark problem but maybe you know something?
