4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	52 Personnally I don't see the rationale for exchanging 3 messages (why 3?)
4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	53 but, if we require at least 1 DWR/DWA exchange to be always performed

4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	85 (reboot, overload, no activity, etc...). In case of unordered delivery,
4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	86 we may have:
4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	87 - peer A sends an application message followed by a DPR. Peer B receives
4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	88 the DPR first and tears down the connection. Application message is lost.
4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	89 - Peer B sends an application message, then receives a DPR and answers a
4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	90 DPA. Peer A receives the DPA before the application message. The
4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	91 application message is lost.
4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	92
4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	93 This situation is actually quite possible because DPR/DPA messages are
4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	94 very short, while application messages can be quite large. Therefore,
4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	95 they require much more time to deliver.
4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	96
4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	97 I really cannot see a way to counter this effect by using the ordering
4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	98 of the messages, except by applying a timer (state STATE_CLOSING_GRACE).

4ffbc9f1e922 Large UNTESTED commit with the following changes: Sebastien Decugis <sdecugis@nict.go.jp> parents: 691 diff changeset	101 that is lost will be in many cases sent again as the failover mechanism
