US LEC, a carrier based in Charlotte, North Carolina, announced the expansion of its MPLS VPN data network, saying it can now provide secure connections across the U.S. and internationally. Speeds may be scaled incrementally from fractional T-1 speeds below 1.544 Mbps to DS3 (up to 45 Mbps) to Ethernet Local Loop at 100 Mbps.

From the Technology Graveyard
You just read about MPLS. Here is what it replaced:
Frame Relay served 1990–2010. What ultimately replaced it?
Frame Relay switched variable-length frames over pre-provisioned permanent virtual circuits, dropping X.25's per-hop error correction (links were now clean) and pushing recovery to the endpoints for far higher throughput. Its job passed to MPLS — but the problem it solved, and the ideas it proved, live on in what replaced it. The standard rests here in the archive. One of 198 technologies here that opened a door and then held it for the next.
