Network Interop March 8 th 2011 Herbst

Ft Lauderdale Review of Herbst/Sturek document submitted to IETF – Suggestions for moving forward – AMI Interfaces

Since Fort Lauderdale Started Weekly Calls 9am-10am PST Fridays

Work items identified IPv4/IPv6 transition – Interworking – Potentially DA focused Transition to NIST approved HAN technology AMI-HAN requirements

IPv4/IPv6 Dual stack routing – No Interworking, “Ships in the night” NAT 64 Higher level application gateway Perhaps Distribution Automation

Legacy HAN -> NIST HAN Transition SEP1.x -> SEP2.0 gateway NIST efforts

HAN impact on AMI Network Messaging Bandwidth/latency Security Documents – Started with OpenHAN SRS v2 – Next steps SAE Documents Zigbee

Example of OpenHAN items Page 13 AMI Definition Page 14 Control & Pricing Signals Page 16 Registration & Enrollment – perhaps commissioning Page 21 High level Security requirements Page27 – High level coms requirement Page 28 item 5 – AMI must be able to tag public vs private message Page 29 item 6 – ami provides backhaul for gas & water, etc DER, PEV Page 30 top paragraph, DER generation data for GridOps Page 30 midpage “innovative applications” Page 32 line 23 – high level ESI requirements Page 33 question on AMI inventory of the HAN device Page 35 high level security – HAN device threat vector Page 35 multiple connections to the home Unique events via multiple paths Might be from different service providers Different Service provider vs network provider identification Page 38 & page 39 – examples of enrolled devices getting load control messages Page 43 - high level control signals Page 43 – Processing Section – various price, control signal and other data needed to process Page 44 – more detail on commissioning, registration, enrollment Page 44 – dynamic ACL’s Page 45 line 45 Over the air upgrade Page 46 – more price and load control Page 46 – Billing information Page 47 – high level security requirements Page 48 – two way load shed (message/confirm) + Cancel events

Logistics of Moving Forward Non-workable approach – Reading/writing long documents in conference calls or meetings Calls should be group reviews – What is appropriate frequency of calls? Co-Chair Independent or small group (2-3 people) submissions
