- The BEST Challenge for Next-Generation Ethernet Services
- Service providers are starting to offer next-generation E-Line (point-to-point) and E-LAN (multipoint-to-multipoint) Ethernet services over their existing SONET/SDH networks. While Ethernet typically is "Best-effort", these emerging services are expected to be "Carrier-class" with strict bandwidth guarantees. Consequently, spanning tree creation, critical to any Ethernet network is fundamentally changed; each tree...
