Network survivability refers to the capability of the network to
maintain service continuity in the presence of faults within the
network . 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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
