  1. RPL Applicability Statement for AMI Jorjeta Jetcheva (jorjeta.jetcheva@itron.com) IETF #81, IETF ROLL WG Québec City, Canada July 25-29, 2011

  2. Scope & Goals • Why we need applicability statement for AMI • AMI in rapid deployment world-wide • Strong momentum in the Smart Grid industry towards utilizing open standards • Document how RPL can be used to meet AMI routing requirements • What this document is NOT • Document is not a deployment guide

  3. Document Overview (draft-ietf-roll-applicability-ami-01) • Introduction • Electric Metering • Gas and water metering • Deployment Scenarios • Network Topology • Traffic Characteristics • Using RPL to Meet Functional Requirements • RPL Profile • RPL Features • RPL Options • Recommended Configuration Defaults & Ranges • Manageability Considerations • Security Considerations • Others: TBD

  4. Sample AMI Deployment Scenario Characteristics • Millions of resource-constrained devices, including meters, DA devices, etc. • Network densities vary widely (1 to 100s of neighbors per node) • Each 1-10K devices form their own routing domain • Traffic between the meter and utility networks goes through one or more Network Aggregation Points (NAPs)

  5. Example AMI Applications • Meter Data Management (MDM) • Unicast & multicast communication between a utility application and the meters • Scheduled traffic, e.g., periodic meter reads • On-demand traffic, e.g., demand reads • Distribution Automation • Delay sensitive & delay tolerant P2P applications

  6. Status • The RPL AMI applicability Internet-Draft addresses one of the ROLL WG charter work items • Thank you for all comments received so far. Some active discussions going on in the following areas: • Comments on Trickle parameterization • Network density considerations • PAP2, SG-Net work at Open-SG/SG-Net • Looking forward to continued discussion/comments/feedback
