The IESG has approved the following document: - 'Building Automation Routing Requirements in Low Power and Lossy Networks ' <draft-ietf-roll-building-routing-reqs-09.txt> as an Informational RFC This document is the product of the Routing Over Low power and Lossy networks Working Group. The IESG contact persons are Adrian Farrel and Ross Callon. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-roll-building-routing-reqs-09.txt Technical Summary The Routing Over Low power and Lossy network (ROLL) Working Group has been chartered to work on routing solutions for Low Power and Lossy networks (LLN) in various markets: Industrial, Commercial (Building), Home and Urban networks. Pursuant to this effort, this document defines the IPv6 routing requirements for building automation. Commercial buildings have been fitted with pneumatic and subsequently electronic communication pathways connecting sensors to their controllers for over one hundred years. Recent economic and technical advances in wireless communication allow facilities to increasingly utilize a wireless solution in lieu of a wired solution; thereby reducing installation costs while maintaining highly reliant communication. The cost benefits and ease of installation of wireless sensors allow customers to further instrument their facilities with additional sensors; providing tighter control while yielding increased energy savings. IPv6 is beoming the accepted technology for use in such environments, but that means that the IP packets must be routed in LLNs. This document examines the specific routing requirements imposed by building automation applications. Working Group Summary No controversy. Document Quality The I-D is informational and specifies IPv6 routing requirements. The I-D has been revised to take advantage of the comments made on previous ROLL routing requirement drafts. Personnel JP Vasseur is the Document Shepherd. Adrian Farrel is the Responsible Area Director. RFC Editor Note Section 5.8 - New first paragraph This section sets out specific requirements that are placed on any protocols that are developed or used in the ROLL building environment in order to ensure adequate security and retain suitable flexibility of use and function of the protocol. --- Section 5.8 OLD FMS systems are typically highly configurable in the field and hence the security policy is most often dictated by the type of building to which the FMS is being installed. Single tenant owner occupied office buildings installing lighting or HVAC control are candidates for implementing low or even no security on the LLN. Antithetically, military or pharmaceutical facilities require strong security policies. As noted in the installation procedures, security policies must be facile to allow for no security policy during the installation phase (prior to building occupancy), yet easily raise the security level network wide during the commissioning phase of the system. NEW FMS systems are typically highly configurable in the field and hence the security policy is most often dictated by the type of building to which the FMS is being installed. Single tenant owner occupied office buildings installing lighting or HVAC control are candidates for implementing a low level of security on the LLN especially when the LLN is not connected to an external network. Antithetically, military or pharmaceutical facilities require strong security policies. As noted in the installation procedures described in Sections 3.3 and 5.2, security policies MUST support dynamic configuration to allow for a low level of security during the installation phase (prior to building occupancy when it may be appropriate to use only diagnostic levels of security), yet to make it possible easily raise the security level network wide during the commissioning phase of the system. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
