Furthermore, I was also wondering, if the bandwidth constraints are upper bounds, what does the traffic distribution typically look like at an LSR? We're interested in traffic within a single service provider, non-Internet traffic. Perhaps most service providers set aside some (dynamic?) pool for Internet traffic, while making commitments to customer's inter-site traffic. Thanks and best regards
