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.

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.
