Concerning MPLS paths

[Saqib Ilyas <msaqib () gmail com>]

Hello everyone
In the context of a single service provider network running MPLS, if a
number of bandwidth constrained LSPs are passing through a particular node
and the sum of the bandwidth constraints for the LSPs is X Mb/s, then is X
the upper bound on the traffic through that node, or is it sometimes
exceeded as well?
Thanks and best regards
