Dear Shen,

first of all I should mention that MPLS deployment is far from being done (I
don't think that it has been deployed even in a large network operator) and
I largely suspect that it will never be deployed in a large scale to be the
primary backbone technology !!!!

>From the point of view of measurement, LSP networks should not have too much
difference from traditional IP networks as nowadays IP routing performance
is getting very  close to Label switching performance, meaning that the
delay of crossing an LSP network should not be significantly larger than an
IP network. The difference may come from a simpler  traffic engineering in
MPLS. Meaning that we should evaluate the effect of traffic engineeringon
performance, not the particuliar behaviour of MPLS network.

Hi there,

I've some question on e2e performance analysis of
label switching path.

There has been many research on e2e performance
analysis for IP routing. Nearly all of them take the
model of "network of queue", and under assumpiton of
Possion Arrival, exponential flow size etc. To my
limited knowledge, this is not to the state of
Internet which experiences LRD. On the other hand,
different router archtecture must have different
effect on transmission performance.
As MPLS proceeds to be the primary backbone
technology, I think there must be something new
introduced into the e2e performance in internet.

So, I want to know, whether there is some work with
methematical modeling of LSP networks? and, are there
anyone would do me a favor to recommend some refrence
book, web page, research paper or the like ?

Thank you very much.

Best regards
