Gigabit Ethernet switches using a shared buffer architecture.

Gigabit Ethernet networks have seen great demand in recent years. This growth was fueled by both an increase in port speed at the client side and new applications in MAN and WAN space. In this article, we report a highly integrated Ethernet switch IC design that supports 12 gigabit ports and one 10...
