Smart Energy v6 CPE Requirements for Enhanced Connectivity

This draft outlines IPv6 and 6LoWPAN requirements for smart energy deployment at residences, using examples from California and beyond. It emphasizes the need for stable and secure Unique Local Addresses (ULAs) in mesh networks and discusses routing protocols and firewall configurations. Additionally, it suggests incorporating mDNS for whole-home service discovery in future CPE development efforts.

  1. Smart Energy v6 CPE Requirements draft-herbst-v6ops-cpeenhancements-00 Tom Herbst Don Sturek

  2. 802.15.4 at every residence • California as an example • 5.5 Million in deployment at PG&E • 5.3 Million in deployment at SCE • 1.4 Million in deployment in San Diego • Texas, Australia, UK, etc

  3. IP on 802.15.4 • IPv6, 6LoWPAN, ND, RPL • RPL is route over – every hop a Link Local • 6LoWPAN ND is not RFC4861 ND

  4. 802.15.4 <-> 802.11requireslayer 3 forwarding

  5. Multiple routers likely ISP Router 802.11 802.3 802.15.4 Utility or Retail router

  6. ULA’s for the HAN • Stable but not Static • Not provider dependent • Locally Routable • Easy to distinguish • Not forwarded to the Internet • More secure

  7. ULA’s in the Mesh 802.15.4 mesh

  8. Multiple ULA problem Generated a ULA prefix 802.11 Generated a ULA prefix 802.15.4 mesh

  9. Need a routing protocol RIPng

  10. Firewall configuration? Incoming Blocked?

  11. mDNS • Use mDNS/DNS-SD for whole home service discovery • Expand scope of mDNSrequests to Site Local • Expand scope of replies to DNS-SD • Draft could have included requirement for whole home multicast

  12. Suggested Next Steps • Incorporate most into CPE document efforts • draft-wbeebee-v6ops-ipv6-cpe-router-bis-04 • mDNS requirements to Cheshire • draft-cheshire-dnsext-multicastdns
