MPLS TE bandwidth

[tbatth]

If RSVP and MPLS TE doesnt actually reserve any bandwidth in hardware(i.e data plane) of the box and doesnt do any qos.  Then what happens if TE with reserved bandwidth of 50 mbps is sending out of data at rate of 100 mbps, and their is another TE trying to setup and wants to use 30mbps, since rsvp has reserved 50 mpbs for previous TE (on 100 mbps link), and it will allow this TE to setup on that link by allocating 30mbps in control plane, when actually that link is being completely used by previous TE in data plane.

I hope I made myself clear.

Hi Tejbir,

MPLS TE  only reserves bandwidth at the control plane level. In the example you gave, both LSPs would get signalled properly but you would need to do admission control on the LSP head end router in order not to oversubscribe any of the links along the LSP.
