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

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.
