Presentation Transcript

  1. Network InteropOpenSG 11/2/10 Tom Herbst

  2. Agenda • Opening • Intro to Interop • IETF Draft for Smart Energy • Ongoing Work

  3. OSI Model

  4. Physical • Layer 1 • Simple Packet forwarding • Repeater • Perhaps change media • 100BaseT – Fiber • Only error checking like CRC

  5. DataLink • Layer 2 • Bridging • Switching • EIU64 or mac addresses • Switch tables • Loop detection/Protection • Spanning tree

  6. Network • Layer 3 • Layer 3 forwarding - Network addresses • IPv4, IPv6, XNS, Appletalk, OSI CLNS • Routing – building the tables for Layer 3 Forwarding

  7. Session/Presentation • Reliability, Sequencing, stateful • TCP • Simple packet transport, stateless • UDP

  8. Application • FTP, Telnet, DNS • HTTP • HTTP+ • Web Services – XML • RestFul Interfaces, SOAP • Application Level Gateway • Expose specific data elements

  9. Common Layer 2 Frames • IEEE 802.3/Ethernet • IEEE 802.11/WIFI • IEEE 1901/Homeplug • Layer 2 Network Interop can be Bridging

  10. AMI to HAN Routed? IPv6 HAN IPv6 AMI

  11. AMI to HAN Application Level Gateway IPv6 IPv6or C12.22 or vendor X Security

  12. Smart Energy Routing Requirements Tom Herbst Don Sturek

  13. IETF Draft draft-herbst-v6ops-cpeenhancements-00 Submitted 10/4/10 To be in v6ops working group at IETF Beijing next week

  14. 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

  15. IP on 802.15.4 • IPv6, 6LoWPAN, ND, RPL • 802.15.4 is 128byte packets • 6LoWPAN does adaptation fragmentation • RPL is route over – every hop a Link Local • 6LoWPAN ND is not RFC4861 ND

  16. 802.15.4 <-> WIFI Needs Layer 3 Forwarding

  17. Multiple routers likely

  18. IPv6 Address Scoping • Link Local • Direct, not routed • Fixed prefix + EUI64 • Unique Local Addresses • Not global • Random formula (or manual assignment) • Globally Unique Addresses • Real Internet

  19. ULA’s for the HAN • Stable but not Static • Routable • Easy to distinguish • Not forwarded to the Internet

  20. ULA’s in the Mesh

  21. Multiple ULA problem

  22. Need a routing protocol

  23. mDNS • Service Advertisement Protocol • Apple Bonjour • Local (link local) scoping as defined by Apple • Global reach via DNS • Need something like the local version, but through a routed home

  24. IETF • Mostly to be incorporated into other CPE work • draft-ietf-v6ops-ipv6-cpe-router-07 • draft-wbeebee-v6ops-ipv6-cpe-router-bis-04 • mDNS • draft-cheshire-dnsext-dns-sd-07

  25. Next Steps • What is useful group work? • Regular call? • Smart Energy 1 on IP • C12.22 on IP • AMI demarc • DLMS.com COSEM • Multi mac/phy SEP2.0
