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

OSI Model

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

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

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

Session/Presentation Reliability, Sequencing, stateful – TCP Simple packet transport, stateless – UDP

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

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

AMI to HAN IPv6 AMI IPv6 HAN Routed?

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

Smart Energy Routing Requirements Tom Herbst Don Sturek

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

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

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

WIFI Needs Layer 3 Forwarding

Multiple routers likely

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

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

ULA’s in the Mesh

Multiple ULA problem

Need a routing protocol

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

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

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
