Call Home BoF Agenda (draft 31 Oct 05) Chair: Eliot Lear (or tbd) Description: Certain protocols, and in particular management protocols where devices on either end of connection take client server roles may be able to take advantage of "Call Home" functionality, when traditional roles are reversed, and a server connect to a client. Examples of existing protocols that make use of call home include SMTP [ETRN] and COPS. At this BoF we will look at extending such functionality into other protocols, as well as any architectural issues this raises. This work stems from efforts in ISMS to extend SNMP to run over SSH, as well as work as work that has gone on in NETCONF. We will begin with a discussion of draft-lear-callhome-description-03.txt, which contains a description of call home, what problems it can solve, and what some of the architectural issues are. During the BoF we may identify additional such issues as well as protocols other than management protocols that could benefit from this work. An additional potential question should be whether a generic standard or process should be used to implement call home, such as rules for SSH. We will also look at other existing work in this space including ICE, STUN, and generic tunneling approaches. There are three possible outcomes: a working group to add "call home" functionality to existing protocols such as SNMP/SSH and NETCONF/SSH, use of existing working groups for this purpose, or nothing.
