S 6.4.1.2 describes a retransmission mechanism for datagram transports but doesn't specify when to give up and assume that the connection has failed. We probably want to specify some sort of drop-dead time. Arguable, this needs to be shorter than the overall message failure time (15 seconds) or messages won't get rerouted properly if a link dies.
On a related note, the TCP transports don't have any kind of explicit ACK at all at the application layer, though of course you will eventually get some TCP transmission failure, which is very slow. Do we want to extend the existing datagram framing to all transports and include a fast timeout? _______________________________________________ P2PSIP mailing list [email protected] https://www.ietf.org/mailman/listinfo/p2psip
