Larscom announced a significant software upgrade for its Orion 7400 Ethernet over SONET (EoS) multi-service access platform. New capabilities include: 1) Ethernet “Q-in-Q” VLAN Tagging support, 2) Advanced Ethernet Performance Management for Service monitoring, and 3) Dynamic WAN bandwidth allocation using LCAS capability. Additionally, the Orion 7400 Release 2 software breaks new ground by providing a full suite of SONET performance parameters for its 10/100 and Gigabit Ethernet interfaces, enabling providers to support a variety of Service Level Agreements (SLAs) by utilizing performance reporting capabilities. The Orion 7400 offers management capabilities via industry standard TL1, SNMP, and HTTP web GUI interfaces. http://www.larscom.com

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.
