martinthomson commented on this pull request. > - -The value for an idle timeout can be asymmetric. The value advertised by an -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 advertises a different max_idle_timeout, but the effective value +is determined by taking the minimum of the two advertised values. By announcing +a max_idle_timeout, endpoints commit to initiating an immediate close +({{immediate-close}}) if it abandons a connection prior to the effective value. + +An endpoint restarts any timer it maintains when a packet from its peer is ```suggestion An endpoint restarts its idle timer when a packet from its peer is ``` > -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. +If the idle timeout is enabled by either peer, a connection is silently closed +and its state is discarded when it remains idle for longer than the minimum of +the max_idle_timeouts (see {{transport-parameter-definitions}}) and three times +the current Probe Timeout (PTO). + +Each endpoint advertises a max_idle_timeout, but the effective value +at an endpoint is computed as the minimum of the two advertised values.
