Title : Link Aggregation Member Interface Status Signal

Link Aggregation can be used as Attachment Circuit (AC) of the PWE3
service. Link Aggregation is treated as a single interface. But
changes in the the member interface may affect use of the aggregated
link.
This draft suggests a method to signal the status of the member
interface of Link Aggregation AC to remote Provider Edge (PE) device.
With this status information, the remote PE can decide to discard
traffic over bandwidth, avoid congestion at local PE and avoid wasted
bandwidth of the Packet Switched Network (PSN).
This mechanism is required in PWE3 applications because pseudo-wires
provide layer 1/layer 2 services, carrying traffic that may not
respond to loss events by executing congestion avoidance

In the body type:
"FILE /internet-drafts/draft-zi-pwe3-link-aggr-member-status-00.txt".
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.
