Slide 1

Network Interop OpenSG 11/2/10 Tom Herbst

Slide 2

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

Slide 3

OSI Model

Slide 4

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

Slide 5

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

Slide 6

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

Slide 7

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

Slide 8

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

Slide 9

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

Slide 10

AMI to HAN IPv6 AMI IPv6 HAN Routed?

Slide 11

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

Slide 12

Smart Energy Routing Requirements Tom Herbst Don Sturek

Slide 13

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

Slide 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

Slide 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

Slide 16

802.15.4 WIFI Needs Layer 3 Forwarding

Slide 17

Multiple routers likely

Slide 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

Slide 19

ULAs for the HAN Stable but not Static Routable Easy to distinguish Not forwarded to the Internet

Slide 20

ULAs in the Mesh

Slide 21

Multiple ULA problem

Slide 22

Need a routing protocol

Slide 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

Slide 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
