Hi,


Can U suggest an example scenario of what U mentioned here with all the
details of link bandwidths ,packet sizes, Type of packets ...etc. As I am
new to this kind of analysis, I don't have any realistic scenario at
present.

Thank U very much

You would need to come up with a scenario where if you use tradional routing versus proper traffic engineering as in MPLS, the difference in the peformance will be clear. However, your scenario should be as realistic as possible, i.e. it can happen in an IP-based network. This is the difficult part. The rest should be easy.
