Hello Howard, Thank you very much for the summary of messages.
A comment on item 12: 12. Prefix stability? SC> I expect that 'Prefix Stability' is a requirement at home or small offices. Without prefix stability some of the applications will suddenly break when the old prefix expires and the new prefix becomes effective. And question to the wg: 8. Support for multiple upstream networks is a requirement. g. Source address selection is out of scope. And should be solved by rfc3484, with longest prefix match (whether ULA or walled garden). Choosing which address to use to look up the destination address is out of scope. SC> Is the expectation from homenet wg that all hosts will implement RFC 3484 ? Do the current home IPv6 host products support RFC 3484 ? [ I don't think so ] So the host implementation change should be required if a host has to support multiple prefixes or I might be missing something? Thanks, -Samita ________________________________ From: homenet-boun...@ietf.org [mailto:homenet-boun...@ietf.org] On Behalf Of Howard, Lee Sent: Friday, October 21, 2011 11:32 AM To: homenet@ietf.org Subject: [homenet] routing requirements I've caught up on some 300 messages about routing. Here are the requirements I've gleaned. Question marks are unclear to me, please help. 1. Homenet router requirements 2. When evaluating a solution, discuss whether it provides for: 3. Reachability between all nodes in the home network. a. Links may be Ethernet, WiFi, MoCA, or any other; test all solutions against mutliple L2 types. 4. Border detection. a. Border may be upstream ISP, or may be a device that is a gateway to SmartGrid devices, e.g. a controller that speaks RPL to 802.15.4 and foo to home net. Or there may be no border, if no external connection has been established. b. Must be able to find "up" (a path to the Internet), but must not be dependent on "up" (Internet connectivity) existing for intra-home reachability. c. May be discovered by routing protocol, or other means. 5. Robust to routers being moved/added/removed/renumbered a. Convergence time a few minutes or less. 6. No configuration required. a. We might tolerate? a single password being entered on each device. Discuss. 7. Best-path is a non-requirement. 8. Support for multiple upstream networks is a requirement. a. Including wireless offload, video-only, and split-tunnel VPN scenarios. b. With separate routers to each. Not multihomed off the same router. c. Prefix delegated from all ISPs (upstreams). d. ISP A is default. e. With only traffic destined to ISP B's prefix using that link. f. With a backup default to ISP B, if desired. What is default condition? g. Source address selection is out of scope. And should be solved by rfc3484, with longest prefix match (whether ULA or walled garden). Choosing which address to use to look up the destination address is out of scope. 9. Cannot assume hierarchical prefix delegation in the home (at least, not unless the WG develops such a solution). 10. A host with mutliple upstream paths to the same destination should be able to use another in case on fails. 11. Prevent looping. 12. Prefix stability? 13. Lightweight (cheap) implementation. Let me know if I've missed, or mistated, anything.
