ETHERNET-PORT AGGREGATION CHIP SLASHES SYSTEM COST

摘要

Today's Ethernet network connections typically operate at under 50% of the available bandwidth utilization due to many factors, but especially the bursty nature of the data being sent. However, equipment aggregating Ethernet links, like switches and routers, are usually designed for 100% link utilization. This results in the underutilization of bandwidth, increased equipment cost, and a reduced number of customers served per system. To maximize revenues per system, an oversubscription-based solution can be used. In this approach, unused bandwidth can be eliminated at the physical connection so the data stream can fully utilize shared hardware, such as the network processors, the backplane, and the switch fabric.
