Abstract:
IETF has been developing IPv6 based standards for Low-power and Lossy
Networks (LLNs) to meet requirements of constrained applications,
such as field monitoring, inventory control and so on. IPv6 Routing
Protocol for LLNs (RPL) has been published in [RFC6550]. Based on
routing metrics and constraints [RFC6551], RPL builds Directed
Acyclic Graph (DAG) topology to establish bidirectional routes for
LLNs for traffic types of multipoint-to-point, point-to-multipoint,
and point-to-point. RPL routes are optimized for traffic to or from
one or more roots that act as sinks. As a result, a DAG is
partitioned into one or more Destination Oriented DAGs (DODAGs), one
DODAG per sink. RPL is widely considered as a feasible routing
protocol for LLNs. However, DODAG loops caused by local DODAG repair
mechanism is an issues to be addressed. This draft introduces a loop
free local DODAG repair mechanism.
