Title : The Optimized Link-State Routing Protocol version 2

This document describes version 2 of the Optimized Link State Routing
(OLSRv2) protocol for mobile ad hoc networks. The protocol is an
optimization of the classical link state algorithm tailored to the
requirements of a mobile wireless LAN.
The key optimization of OLSRv2 is that of multipoint relays,
providing an efficient mechanism for network-wide broadcast of link-
state information. A secondary optimization is, that OLSRv2 employs
partial link-state information: each node maintains information of
all destinations, but only a subset of links. This allows that only
select nodes diffuse link-state advertisements (i.e. reduces the
number of network-wide broadcasts) and that these advertisements
contain only a subset of links (i.e. reduces the size of each
network-wide broadcast). The partial link-state information thus
obtained allows each OLSRv2 node to at all times maintain optimal (in
terms of number of hops) routes to all destinations in the network.
OLSRv2 imposes minimum requirements to the network by not requiring
sequenced or reliable transmission of control traffic. Furthermore,
the only interaction between OLSRv2 and the IP stack is routing table
management.
OLSRv2 is particularly suitable for large and dense networks as the
technique of MPRs works well in this context.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
