Subject: [mpls] Deadline extended on the operator survey for LDP deployments

From: Ina Minei <[email-masked]>
Date: Tue, 2 Nov 2004 16:11:01 -0800 (PST)

Many thanks to those of you who have already replied!

	I have received several requests to extend the deadline - the new
deadline is November 16 (after the ietf).

	If you haven't done so already, please fill out the survey
(attached here again). It should only take a few minutes to a person
familiar with the network. The replies can be made confidential, please
see below for full details.

			Thank you,

				Ina
