	Title		: Network Survivability Considerations for Traffic

Network survivability refers to the capability of the network to 
maintain service continuity in the presence of faults within the 
network [1]. This can be accomplished by recovering quickly from 
network failures quickly and maintaining the required QoS for existing 
services. With the increasing sophistication of network technologies, 
survivability capabilities are becoming available at multiple layers, 
allowing for protection and restoration to occur at any layer of the 
network. This makes it important to: scrutinize the recovery features 
of different network layers, understand the pros and cons of performing 
recovery at each layer, and assess how the interactions between layers 
impact network survivability. With these objectives in mind, this draft 
examines the considerations for network survivability at different 
layers of the network.

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.
