摩尔定律告诉我们：硅片上所实现的功能每18个月就会翻一番。千兆位以太网(GbE)路由器产品的更新换代似乎同样遵守这一定律。过去的3年里我们见到了两代GbE路由器，这些均直接受益于处理器和ASIC的进步。第一代商用GbE路由器出现于1998年，作为核心路由器使用。它们从最初为基
Moore’s Law tells us that the capabilities implemented on a silicon chip double every 18 months. The replacement of Gigabit Ethernet (GbE) routers seems to follow this same principle. We’ve seen two generations of GbE routers in the past three years, all directly benefiting from advances in processors and ASICs. The first commercial GbE router appeared in 1998 as a core router. They are based from the beginning
