GROBJ (Generic Referral Object) BOF The purpose of a referral is to enable a given entity in a multiparty application to pass information to another party. Existing referrals are IPv4 address only (with implied port number) or are IPv4 address+port. But, with IPv6 deployments and the need for compatibility with existing IPv4 applications, referrals will need to be more generic, providing a richer language for IPv4 and IPv6 address referrals, and fallbacks for when neither of these is directly applicable. This BOF will consider a proposed Generic Referral Object (GRO) to be used for referrals. The proposed object is compact and is application- independent. Both IPv4 and IPv6 schemes are supported, as well as upper layer identifiers. Additional information to characterise an enclosed reference is also includeded. To allow proper interpretation of referrals, a new notion of scope identifiers is introduced. GRO's richer language helps peers avoid address translators or tunnels and to choose a reachable path with the desired characteristics. See draft-carpenter-behave-referral-object The purpose of the BOF is to expose these ideas to a wider spectrum of people including Apps Area experts and to discuss whether to take the ideas forward in the IETF.
