Does anyone out there know exactly what AT&T is deploying for their any to any MPLS VPN service. Specifically what devices are used. (BPX, MGX ?). Is it frame-based or cell-based or both. How are the enforcing the Committed Delivery Rate (CDR). And some other questions. If you have any knowledge, would you email me for an off-list private conversation.
