由于价格因素的制约,以及产品自身升级能力的缺陷,目前,万兆产品还局限在核心骨干层应用,对于现有边缘、汇聚层交换机产品,主要还只是通过千兆端口Trunk技术进行带宽扩展。Extreme在理解到汇聚层需要万兆带宽的应用需求,率先推出了带有10G上连的固定48端口交换机Summit400-48,
Due to the restriction of price factors and the defect of product upgrade capability, at present, 10GbE products are still limited to the core backbone layer. For existing edge and convergence switch products, the bandwidth extension is mainly through the Gigabit Trunk technology. Extreme understands the convergence layer needs 10 Gigabit bandwidth applications, the first to introduce a fixed 48-port switch with 10G Summit400-48,
