IMO there is a disconnect between the BoF charter text below and the email discussions I (mostly) followed in the last month. I am in favor of sharply defined work that will achieve integration between NETCONF and ISMS through foresight and planning. I'm not so keen about the open-ended charter text below. [IMO, this feature is simply defined as "the NETCONF peer acting in the agent role initiates the session establishment". There may be additional ISMS requirements, but I don't know.] I suspected (back at the first NETCONF interim in Sunnyvale) that our decision to provide this "reverse connect" feature for BEEP only would come back to bite us -- then even more when we picked SSH as the mandatory transport. I think this functionality is important enough to be available via the mandatory transport. (IMO the work can be done as an extension to the 1.0 specification set.) Beyond the firewall/NAT issues, I think there are some important use cases for this feature, especially when notification generator applications are introduced in NETCONF. Issues such as mobility, scale, and auto-configuration may make applications a lot easier to design if the agent connects to the manager. > > Eliot Andy > > Title: callhome > Period of time: 1 hour > Area: ops-nm > Expected # attendees: 40-60 (small room) > Don't conflict with: ISMS, ops-area, netconf (if there is one) > > > Short Description: Discussion of Architectural Issues Concerning > protocols that could benefit from reversing > of roles > > Long 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.
