Lantern Communications, a start-up based in San Jose, California, announced Ethernet VLAN stacking and Cross-Node Protection Switching for its Metro Packet Switch, which is a flow-based Resilient Packet Ring (RPR) platform that supports both 2.5 Gbps and 10 Gbps ring topologies. Ethernet VLAN stacking enables a service provider to create an Ethernet VPN that tunnels a customer’s VLANs across the wide area, preserving the integrity of the customer’s Ethernet traffic. Lantern’s Cross-Node Protection Switching uses IEEE 802.3ad link aggregation technology to protect Ethernet services in the event of equipment (port, module or node) or fiber failures. Lantern said these features have been successfully tested with switches from Extreme Networks and Cisco Systems.

From the Technology Graveyard
You just read about Ethernet. Here is what it replaced:
Token Ring (802.5) served 1985–2000. What ultimately replaced it?
Token Ring (802.5) stations passed a small 'token' frame around a logical ring; only the token-holder could transmit, giving deterministic, collision-free access at the cost of ring-management overhead. Its job passed to Ethernet — 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.
