Hi, all respectable RTCWEB experts: Here we propose one draft that can cover peer to peer communication scenario under various complex network environment(Cone/Symmetry NAT, IPv4&IPv6 Coexistence etc.) with the unified solution. https://tools.ietf.org/html/draft-wang-rtcweb-oars-00 This document proposes a new relay-based NAT traversal architecture called OARS which could simplify the data communication process between two hosts that locates behind some non-BEHAVE compliant [RFC4787 <https://tools.ietf.org/html/rfc4787> ] [RFC5382 <https://tools.ietf.org/html/rfc5382> ] NAT devices. The key mechanism in OARS is the newly defined "Couple" operation (using STUN [RFC5389 <https://tools.ietf.org/html/rfc5389> ] message format) which allows the Relay servers to be easily incorporated into existing CGN/CDN nodes which are already deployed within the network in a distributed manner. One brief introduction can be accessed at https://www.ietf.org/proceedings/96/slides/slides-96-tram-1.pdf, wish to hear your valuable comments on this topic. Best Regards.
