The intention of the sentence in the ID is that you can not send multiple HeartbeatRequest out. This could overload the network since DTLS uses transport layers which do not necessary provide a congestion control. That is why you can only have one request in flight. Please note that it is not in flight anymore if the corresponding HeartbeatReply has been received or the retransmission timer fires. > > The original requirement seems to be pretty much unimplementable > because of transport layer characteristics. Not sure what problem you are thinking about. An implementation of the ID for OpenSSL is available at http://sctp.fh-muenster.de/dtls-patches.html Best regards Michael > > -- > Florian Weimer <fweimer@bfk.de> > BFK edv-consulting GmbH http://www.bfk.de/ > Kriegsstraße 100 tel: +49-721-96201-1 > D-76133 Karlsruhe fax: +49-721-96201-99 > _______________________________________________ > TLS mailing list > TLS@ietf.org > https://www.ietf.org/mailman/listinfo/tls >
