Subject: Usage of UDP ports for CESoPSN

Stewart and all,
Please look at the following quote from Section 4.2 of
draft-ietf-pwe3-cesopsn-01.txt:
<quote>
	Usage of UDP as the multiplexing mechanism is compliant with the 
	traditional method used for multiplexing RTP flows, e.g.: 
 
	1. Each PE: 
	    a) Allocates one of the PE own IP addresses and a single UDP
port 
	       for each local PW end point (CESoPSN IWF instance)  
	    b) Is aware (by configuration or via a signaling protocol) of
the 
	       similar allocations associated with the remote peer PW end 
	       points 
	2. Each CESoPSN IWF instance uses the associated locally and
remotely 
	   allocated UDP ports as correspondingly the Source and Destination

	   UDP ports in all the CESoPSN packets its generates. 
<end quote>

Hopefully this is sufficiently unambiguous.
