Re: I-D ACTION:draft-wlai-tewg-bcmodel-02.txt,.pdf

My question:
 
How does the assumpiton of Possion Arrival and Erlang measurement relates to real network senerion? 
 
Why does the draft states "This allows us to express link 
   bandwidth usage simply in terms of the *number of simultaneously 
   established LSPs*"?  To my understanding, even overbooking is adopted BC should be interpreted as " the bandwidth utilized by special TC", because we could not assume every LSP has the same bandwidth requirement.

Title : Bandwidth Constraints Models for Diffserv-aware MPLS 
Traffic Engineering: Performance Evaluation
Author(s) : W. Lai
Filename : draft-wlai-tewg-bcmodel-02.txt,.pdf
Pages : 18
Date : 2003-6-27

The Diffserv-aware MPLS Traffic Engineering Requirements RFCxxxx 
specifies the requirements and selection criteria for bandwidth 
constraints models. Two such models, the Maximum Allocation and the 
Russian Dolls, are described therein. This document complements 
RFCxxxx by describing in more details some of the selection criteria 
and their implications. Results of a performance evaluation of the 
two models are also included.

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
