Slide 7

Network Interoperability• Tom Herbst from Silver Spring Networks is the chair• Internet Protocol (IP) use is assumed• Since we are using IP, draft requirements document needs to

address the following types of issues as they apply across platforms:– Collection of RFCs used (from SE 2.0 TRD)– Security protocols and cipher suites (from SE 2.0 TRD)– Application support protocols (from SE 2.0)– Policies, procedures and other considerations (eg firewalls,

etc.) that are needed for cross platform deployments– What else?

• Co-existance for PLC

Slide 8

Network Interoperability• From the draft Scope/Charter:

– Identify and articulate premise Network Interoperability requirements. Engage with Standards Development Organizations (SDOs) and vendor consortiums to realize realize implementation specifications and conformance programs based on the requirements.

– Premise networks cover commercial, industrial and home area networks employing OpenSG requirements specifications. Ensure that the Network Interoperability requirements cover all market segments.

– Align all premise Network Interoperability requirements with the NIST Smart Grid Interoperability Guidelines (Version 1.0 and any subsequent updates).

February 2010

Slide 9

Network Interoperability• Proposed deliverables:

– Creation of a Network Interoperability System Requirements Specification for premise platforms employing multiple physical network interfaces;

– Outreach and engagement with SDO’s and vendor consortiums embracing and deploying the Network Interoperability System Requirements to realize standards and conformance programs based on the requirements;

– The Network Interoperability Task Force will create, distribute and maintain a schedule and roadmap detailing the tasks and milestones that comprise the group's work;

– The Task Force shall assist the Conformity Task Group in their job in defining the test plans and protocol interchange conformance statements (PICs) to apply certification to the components in its charter..

Network Interoperability• Call for participation:

– Please e-mail: Don Sturek, d.sturek@att.net– Email reflector - www.smartgridlistserv.org

• OPENSG-SGCOMM-NETINTEROP

• Process:– Update/approve the draft Scope/Charter– Submit to OpenSG TC for approval– Review the Requirements Specification Outline,

update/approve and begin work– Outreach to SDO’s, vendor consortiums:

• IETF, IEEE• ZigBee Alliance, HomePlug Alliance• Other SDO’s and vendor consortiums working on SE 2.0

Questions?

SG-Network Overview• Previously started as AMI-Network with a focus on

network management.• Scope and Charter for SG-Network within UCAiug– NIST PAP 2 (Wireless standards for the Smart Grid)• Supply functional requirements for Smart Grid

Networks from a utility perspective• Define functional domains within the Smart Grid

– Create a System Requirements Specification• Provide information to SDO’s (e.g., IEEE P2030)

• Participation– Utilities, Academia, Vendors

SG-Network• Work underway– Selected 30+ SG use cases for requirements– Defined 75 total actors from the use cases– Alignment with NIST and other sources to create an

architecture diagram for reference– Functional Requirements Definition (3100+ identified to

date, was 2400+ before the Detroit meeting)– Define latency requirements (How long)– Define volumetric information (How often)

Examples of work accomplished to date• Sample Actors– Smart Meter– Load Management System (LMS)

• Sample Requirement for a Smart MeterUse Case Requirement How Often Reliability Latency

Meter reading

Smart Meter shall be able send on demand read information

1 transaction per meter on demand

> 98% < 5s

Meter reading

Smart Meter shall be able to report on demand read communication failure

1 transaction per meter on demand

> 98% < 5s

Meter reading

Residential Electric Smart Meter shall be able to report when scheduled

All meters report 4-6 times per day

> 98% < 4hr

SG-Networks Reference Architecture

Deliverables• Interim Release 1.0 was published in December 2009

– Requirements and some volumetric and latency requirements• Interim Release 2.0 was published in February 2010

– Requirements, volumetric, latency requirements, security, implications and more use cases

– Reference Architecture Diagram first published– System requirements specification published

• Interim Release 3.0 was published in May 2010– Addition of the following use cases: Pre-Payment, Meter Events, DA and

Outage Management– System requirements specification updates

• Interim Release 4.0 was published in June 2010– Addition of the following use cases: DRLC, DA fault isolation and

reconfiguration– System requirements specification re-write

Work Plan for the week• Review Joint SG-SEC/SG-NET meeting to

review security portions of requirements (Confidentiality, Integrity, Availability)

• System requirements Specification working sessions

• Review Requirements Database• Plan scope of the next interim release• PAP 2 joint meeting Thursday
