Unifying Smart Grid Communications using SIP Joe DiAdamo, P.Eng. Chief Technologist, Smart Grid Siemens Enterprise Communications Sept 1, 2009 One of, I think, the most important infrastructure projects that we need is a whole new electricity grid And we're going to have to have a smart grid President Barack Obama, Oct 30, 2008

Beyond Connectivity Key Concerns for Utilities Cyber Security How to keep the Smart Grid secure with ever evolving cyber threats? Costs How to keep costs of deployment and operations under control? Complexity How to build the infrastructure out systematically, across applications? Future-proof How to protect investments against technology evolution? Interoperability and Standards How to achieve interoperability and migration to upcoming standards? SIP-based Session Initiation Protocol IETF protocol on top of IP Most widely used protocol for unified communications Extensible to device communications 7

SIP-enabled Smart Grid Always at the Forefront of Cyber Security Threat Protection SIP uses leading IP-based security mechanisms such as TLS and IPSec Leverage industry updates and advances SIP uses dynamic selection of security mechanism by end-points SIP maintains security across network borders SIP is traceable, auditable Keep pace with your IT security policy, deploy and increase security in stages if required Support for outsourcing business models as well as 3 rd -party participation in Smart Grid Required by programs such as NERC-CIP, Sarbanes-Oxley 11
SIP-enabled Smart Grid Path to Interoperability SIP is designed for interoperability - application-specific protocols are negotiated by end-points using SIP Interoperability in a world of many existing standards and protocols SIP is designed for extensibility - new functionality is easily integrated No dead-end road when new use-cases or technologies arise SIP has industry-wide support - IEFT, ETSI, ECMA, etc. Investment into future-proof technology SIP is on NIST Smart Grid Roadmap list of technologies to evaluate Investment into emerging Smart Grid standard 12
SIP-enabled Smart Grid Unique, Extended Feature Set SIP is designed for Mobility of endpoints Technological basis to support mobile metering in electric cars SIP has integrated many extensions, such as Geospatial location Immediately useable by Smart Grid applications, faster time to market SIP proxy servers can serve as relay points for multicast scenarios E.g. Send price signal to millions of devices simultaneously SIP allows meters to be connected with multiple entities Supports and segregates access for utilities, retailers or providers SIP supports message redirection and forking Redundancy, availability 3 rd -party data sharing 13
SIP-enabled Smart Grid Unifying Device and Workforce Communications One infrastructure for all communications along the grid Lower costs and complexity, higher ROI, single skill set A common session management protocol for devices and applications Discovery/mobility, negotiate security and application protocols Communication across any IP network Intranets, extranets, securely across boundaries Light-weight for embedded devices Home automation, meters, etc. Mobile Workforce Communications and Collaboration Field crews fully integrated into utility's IP communications and Workforce Automation 14
