janaiyengar commented on this pull request. > -endpoint is only used to determine whether the connection is live at that -endpoint. An endpoint that sends packets near the end of the idle timeout -period of a peer risks having those packets discarded if its peer enters the -draining state before the packets arrive. If a peer could timeout within a -Probe Timeout (PTO; see Section 6.3 of {{QUIC-RECOVERY}}), it is advisable to -test for liveness before sending any data that cannot be retried safely. Note -that it is likely that only applications or application protocols will -know what information can be retried. +Each endpoint can advertise a different idle timeout value. An idle timeout +indicates the connection will be abandoned when the timer ends or soon +afterwards. If a peer advertises a smaller idle timeout value than the +local endpoint, the local endpoint MAY choose to idle timeout after the +shorter period advertised by the peer. By announcing an idle timeout, +an endpoint commits to initiating an immediate close ({{immediate-close}}) +if it abandons a connection prior to both its peers and its own idle timeout +expiring. I don't think I follow this sentence. What is the endpoint committing to? To closing the connection at min(local_timeout, remote_timeout)? > -period of a peer risks having those packets discarded if its peer enters the -draining state before the packets arrive.
