Question about DATAGRAM frame #54

Closed wangweiwei1188 closed 3 years ago

wangweiwei1188 commented 3 years ago

The draft has the following words: This document defines two new DATAGRAM QUIC frame types, which carry application data without requiring retransmissions.

The draft don't describe it like:When DATAGRAM frame is lost, the implemention should not retransmission it.That's to say, when DATAGRAM frame's lost, the implemention have two strategy，one for retransmissing, another for not.That's right?

DATAGRAM frames are never retransmitted. The reason there are technically two frame types is that there’s a version that includes it’s length, and a version that just extends to the end of the packet. That’s just like STREAM frames.

Does this answer your question @wangweiwei1188 ?
