The Role Of SIP In Smart Grid Networks

  1. 1. SIP Inside of Smart Grid Networks Managing a Smart Grid with Operational Efficiency Bill Leslie LongBoard Technologies Show Logo Goes Here Copyright © 2010 SIP Forum
  2. 2. Rationale for IP-based Smart Grid Networks IP-based networks will serve as a key element for Smart Grid information networks Benefits of using IP-based networks include: maturity of a large number of IP standards availability of tools and applications that can be applied to Smart Grid environments widespread use of IP technologies in both private and public networks allow applications to be developed independent of the communication infrastructure and technologies used enable bandwidth sharing among applications and increased reliability with dynamic routing capabilities Grid ComForum Copyright © 2010 SIP Forum
  3. 3. What IP Protocols to use inside of the Smart Grid? NIST asked IETF for a document that identifies: the structure of the Internet Protocol suite the key protocols that should be considered as critical in integrating Smart Grid devices into an IP-based infrastructure. IETF responded with the following informational Internet-Draft http://tools.ietf.org/html/draft-baker-ietf-core In it Session Initiation Protocol (SIP) is identified as the protocol for multi-media session management in the Internet Grid ComForum Copyright © 2010 SIP Forum
  4. 4. What is SIP? SIP is an application layer control (signaling) protocol for creating, modifying and terminating multi-media sessions on the Internet Multi-media sessions can be voice, video, instant messaging, shared data and subscriptions of events SIP is independent of the transport layer and independent of the underlying IPv4/v6 version Defined in RFC 3261, RFC 3265, RFC 3853, RFC 4320, RFC 4916, RFC 5393, RFC 5621 Grid ComForum Copyright © 2010 SIP Forum
  5. 5. Why use SIP in the Smart Grid? Mature protocol, yet easily extensible Proven to be secure, inter-operable, reliable and scalable Independent of underlying physical transport network, media type and end devices Ability to inter-work with other protocols Devices are addressed using a flexible URI based scheme (independent of IP address) Supports offer/answer and subscribe/notify models Existing body of products that can be re-purposed for use in Smart Grids Grid ComForum Copyright © 2010 SIP Forum
  6. 6. Common Misconceptions about SIP SIP is a telephony/VoIP protocol Supports multi-media sessions which can be voice, video, instant messaging, shared data, and/or subscriptions of events SIP has problems with NATs and Firewalls NAT issues primarily occur when IP address are embedded in SDP Session Traversal Utilities for NAT (STUN) [RFC 5389] can be used to overcome these issues Grid ComForum Copyright © 2010 SIP Forum

  8. 8. What is the SIP Forum? The SIP Forum's mission is to advance the adoption of products and services based on SIP To accomplish its mission, the Forum: Advances product interoperability by holding live interoperability test events Develops industry-wide technical recommendations and best- practice implementation guides Creates white papers and other documents that cover essential aspects of developing and deploying SIP-related IP communications technology, products and services Builds awareness about what existing and emerging SIP-compliant technologies can do for users and customers Maintains a growing community of IP Communications industry professionals interested in SIP Grid ComForum Copyright © 2010 SIP Forum

SIP Forum Member Activities for Smart Grid Smart Grid Special Interest Group formed http://www.sipforum.org/content/view/351/266/ Weekly conference calls held Developing whitepapers Applicability of SIP in Smart Grid Demand & Response Communication The Role of SIP in the Smart Grid HAN Authoring articles and speaking at events SIP Forum member companies are working on SIP products for the Smart Grid Grid ComForum Copyright © 2010 SIP Forum
