As part of Isocore’s IP/Optical Integration demonstration held in conjunction with this week’s MPLS 2003 International Conference, Sycamore Networks demonstrated Generalized Multi-Protocol Label Switching (GMPLS) multivendor interoperability. The demonstration featured an optical control plane using GMPLS signaling and routing protocols, and included Sycamore’s SN 16000 Intelligent Optical Switch as well as equipment from industry-leading Layer 2/Layer 3 networking vendors and other optical layer equipment.

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.
