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 and lack of a loop free DODAG
local repair mechanism are two open issues to be addressed. This
draft introduces an alternative rank and an Objective Function to
eliminate DODAG loops in RPL. Based on the proposed rank and
Objective Function, this draft introduces a loop free DODAG local
repair mechanism.
