Future Gateway Architecture Issues • Security – Smart Energy HANs have their own security

Future Gateway Architecture Issues • Security – Smart Energy HANs have their own security profiles – Need to maintain sufficient security levels in other networks if they tie into utility-related data • Demand response, billing grade data, OTA upgrades are highest security requirements • Future IP based HAN Support Issues – Legacy 802. 15. 4 radio – Interoperability of IP 6 Lo. Pan and others – Means to sequence through GW and HAN devices to insure a successful protocol update occurs Company Confidential 2

Future Gateway Architecture Issues • Distributed Intelligence Model – Reduce external IP traffic for

Future Gateway Architecture Issues • Distributed Intelligence Model – Reduce external IP traffic for scalability – Manage FW upgrades locally – Support features such as: • • Household peak limit Neighborhood peak limit Local Data logging and analytics Interaction with other home networks – (Turn off thermostat if window open, etc. ) Company Confidential 3

Future Gateway Architecture Issues • Multiple ESP's, Hybrid networks – Connecting GW’s and AMI

Future Gateway Architecture Issues • Multiple ESP's, Hybrid networks – Connecting GW’s and AMI meters in one HAN • Both are currently ESPs, and many devices assume the ESP = coordinator • Only one coordinator per HAN allowed – Add another radio to support legacy AMR meters – Gas meters – Water meters Company Confidential 4
