	Title		: Quality of Service for Ad hoc Optimized Link State Routing Protocol (QOLSR)
	Author(s)	: H. Badis, et al.

The Optimized Link State Routing (OLSR) protocol for mobile ad hoc    
networks provides shortest routes in terms of number of hops using 
Dijkstra's shortest path algorithm. In order to support multiple-
metric routing criteria, a quality of service (QoS) extension can 
be added to OLSR functioning. No additional control traffic is 
generated (only augmented HELLO and TC messages). QOLSR protocol
uses standard multipoint relays (MPRs) to ensure that the overhead
is as low as possible for forwarding control traffic. Local QoS 
metrics information on links are used to calculate quality of service
MPRs (QMPRS) and then flooded in the network by TC messages to 
calculate routing tables. QOLSR can find optimal paths on the known 
partial topology having the same bandwidth performances that those 
on the whole network. These paths contain only QMPRs as intermediate
nodes between a source destination pair. 

This memo describes the QOLSR protocol, which is an enhancement of 
OLSR to support multiple-metric QoS routing.

In the body type:

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.
