![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

The Role Of SIP In Smart Grid Networks

- 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. 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. 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. 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
