Multipath Extension for the
Optimized Link State Routing Protocol Version 2 (OLSRv2)
Abstract
This document specifies a multipath extension for the Optimized Link
State Routing Protocol version 2 (OLSRv2) to discover multiple
disjoint paths for Mobile Ad Hoc Networks (MANETs). Considering the
characteristics of MANETs, especially the dynamic network topology,
using multiple paths can increase aggregated throughput and improve
the reliability by avoiding single route failures. The
interoperability with OLSRv2 is retained.
Status of This Memo
This document is not an Internet Standards Track specification; it is
published for examination, experimental implementation, and
evaluation.
This document defines an Experimental Protocol for the Internet
community. This document is a product of the Internet Engineering
Task Force (IETF). It represents the consensus of the IETF
community. It has received public review and has been approved for
publication by the Internet Engineering Steering Group (IESG). Not
all documents approved by the IESG are a candidate for any level of
Internet Standard; see Section 2 of RFC 7841.
