Thanks, I've added reference to RFC 5764, Section 6.7 in Section 6.2.4, at end of this second paragraph: <t>In order to facilitate the initial establishment of NAT bindings, and to maintain those bindings once established, BFCP entities using unreliable transport are RECOMMENDED to use STUN <xref target="RFC5389"/> Binding Indication for keep-alives, as described for ICE <xref target="RFC5245"/>. <xref target="RFC5763"/>, Section 6.7 provides useful recommendations for middlebox interaction when DTLS is used.</t> -- Tom On 11/28/2012 10:49 PM, Charles Eckel (eckelcu) wrote: > (as an individual) > Adding a reference to 6.7.2 of RFC 5763 sounds like a good idea to me, and I agree that rfc4582bis is probably a more appropriate place for this than rfc4583bis. > > Cheers, > Charles > > >> -----Original Message----- >> From: bfcpbis-bounces@ietf.org [mailto:bfcpbis-bounces@ietf.org] On >> Behalf Of Tom Kristensen (tomkrist) >> Sent: Wednesday, November 28, 2012 6:36 AM >> To: bfcpbis@ietf.org >> Subject: Re: [bfcpbis] BFCP-UDP and DTLS >> >> Thanks Christer, >> >> In the upcoming version of rfc4583bis, the usage of the RFC 4145 'setup' will >> be described (in Section 8).
