I am new to MPLS and would like to see if anyone can offer some insight to my questions.
We have a OC-3 connection to our MPLS provider (AT&T). We have various (100+) remote sites all over the global that have different connections to the MPLS network (T1, T3, 10Mb ethernet, etc.).
Is there any protection inherent within MPLS that would prevent the oversubscription of smaller links (OC-3 to T1)?
Is it possible my provider might limit traffic?
How could I possibly write a QoS policy when 20% of the head-end is larger than 100% of the remote end?
I'm trying to find the "nicest" solution in regarding to TCP/IP. I hear that policing is rather harsh on the windowing mechanism, and that shaping is a better option.
Would it be as simple as creating some type of nested QoS policy?
