Description Large networks require a powerful routing device capable of delivering data quickly and efficiently, regardless of the data's protocol, the network's topology, or other factors. Since networked applications are mission-critical in nature, network downtime must be zero. Users require routers that provide the greatest number of WAN interfaces and can produce the highest throughput from expensive WAN bandwidth. As more applications use multicast and Quality of Service (QoS) features, customers also want their investments to continue to perform into the future. Nortel Networks meets these requirements with the Backbone Node (BN) router family, consisting of the Backbone Link Node (BLN) and Backbone Concentrator Node (BCN).
