One advantage that MPLS provides is that it allows traffic to be
directed through an explicit path that deviates from IP routing.
Such ability is widely used in traffic-engineering and fast-reroute.
Currently signaling protocols such as RSVP is needed to establish and
maintain such an explicit Label Switched Path. When there are a large
number of such signaled LSPs in the network, the aggregated signaling
and maintenance overhead can be significant.
In this paper, we propose a way to establish a source routed explicit
path with zero signaling overhead. The scheme uses a stack of labels
and requires domain wide LDP FEC to label bindings.

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
Internet-Draft.
