A modified charter has been submitted for the Behavior Engineering for Hindrance Avoidance (behave) working group in the Transport Area of the IETF. The IESG has not made any determination as yet. The modified charter is provided below for informational purposes only. Please send your comments to the IESG mailing list (iesg@ietf.org) by Tuesday, May 22, 2012. Behavior Engineering for Hindrance Avoidance (behave) ----------------------------------------------------- Current Status: Active Last updated: 2012-05-10 Chairs: Dan Wing <dwing@cisco.com> Dave Thaler <dthaler@microsoft.com> Transport Area Directors: Wesley Eddy <wes@mti-systems.com> Martin Stiemerling <martin.stiemerling@neclab.eu> Transport Area Advisor: Wesley Eddy <wes@mti-systems.com> Mailing Lists: General Discussion: behave@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/behave Archive: http://www.ietf.org/mail-archive/web/behave Description of Working Group The working group creates documents to enable IPv4/IPv4 and IPv6/IPv4 NATs to function in as deterministic a fashion as possible. To support deployments where communicating hosts require using different address families (IPv4 or IPv6), address family translation is needed to establish communication. In BEHAVE's specification work on this topic it will coordinate with the V6ops WG on requirements and operational considerations. "An IPv4 network" or "an IPv6 network" in the descriptions below refer to a network with a clearly identifiable administrative domain (e.g., an enterprise campus network, a mobile operator's cellular network, a residential subscriber network, etc.). It will also be that network that deploys the necessary equipment for translation. BEHAVE will finish four scenarios: (1) An IPv6 network to IPv4 Internet, (2) an IPv6 Internet to an IPv4 network, (3) an IPv6 network to an IPv4 network, and (4) an IPv4 network to an IPv6 network. Specifically, BEHAVE will update the NAT MIB (RFC 4008) to be consistent with the management aspects of its IPv6/IPv4 NAT solutions, and specify IPFIX information elements to meet logging requirements, reusing existing elements, if possible. In addition, when a NAT (such as a NAT64 in the "An IPv6 network to IPv4 Internet" scenario) serves multiple subscribers, inter-subscriber fairness issues arise. As such, BEHAVE will complete its work on Carrier Grade NAT requirements for such scenarios, and update the NAT MIB as needed to meet such requirements. BEHAVE will not, however, standardize IPv4-specific behavioral mechanisms. The following scenarios remain in scope for discussion, but will not be solved by BEHAVE: * An IPv4 network to IPv6 Internet, i.e. perform translation between IPv4 and IPv6 for packets in uni- or bi-directional flows that are initiated from an IPv4 host towards an IPv6 host. The translator function is intended to service a specific IPv4 network using either public or private IPv4 address space. * IPv4 Internet to an IPv6 network, i.e. perform translation between IPv4 and IPv6 for packets in uni- or bi-directional flows that are initiated from an IPv4 host towards an IPv6 host. The translator function is intended to service a specific IPv6 network where selected IPv6 hosts and services are to be reachable. This group will also provide reviews of any work by the MBoneD WG on multicast translation, including control traffic (IGMP and MLD), Single Source Multicast (SSM) and Any Source Multicast (ASM). If the WG deems it necessary, BEHAVE will revise RFCs previously published by BEHAVE. Goals and Milestones Done Submit BCP that defines unicast UDP behavioral requirements for NATs to IESG Done Submit a BCP that defines TCP behavioral requirements for NATs to IESG Done Submit a BCP that defines ICMP behavioral requirements for NATs to IESG Done Submit informational that discusses current NAT traversal techniques used by applications Done Submit BCP that defines multicast UDP Done Submit revision of RFC 3489 to IESG behavioral requirements for NATs to IESG Done Submit informational document for rfc3489bis test vectors Done Submit experimental document that describes how an application can determine the type of NAT it is behind Done Submit BCP document for DCCP NAT behavior Done Determine relative prioritization of the four translation cases.
