It is possible for link-state routing protocols to converge in link
propagation time scales, that is, in tens of milliseconds. However,
current deployments of ISIS[ISIS-ISO][ISIS-IP], a link-state routing
protocol, are not anywhere near this point. In this paper, we present
some analyses of ISIS convergence by showing its behavior upon
link/router failures and repairs, and its scaling properties to
large networks, both in terms of number of nodes and links. We
then explore changes needed in the ISIS specification and implementations to reach IGP convergence in milliseconds. Our results are based on experimentation done with ISIS, but some of the findings may apply to OSPF as well.

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.
