[c-nsp] FW: L2 network - MPLS question

[Laurent Dumont]

What do you mean by "the response was slow"? Do you mean that he's not 
getting the full 1Gb speed? I don't think many content providers will 
actually offer full Gig throughput for downloads. Do you experience 
packet loss, high latencies?

Customer site WAN link may be anywhere from 100Mbps up to 3 or 4 Gbps based on size of the location.

We had vendor come out and run tests using their JDSU devices. From the results of that test I am convinced that *using this tool* they can see 1Gbps of throughput from customer site to our aggregation site.
