Description
An Ethernet switch is used to interconnect a number of Ethernet local area networks (LANs) to form a large Ethernet network. Different ports of the switch are connected to different LAN segments. The purpose of the switch is to forward the packets only to the desired destination segment of the network whenever possible, minimizing traffic on the network. MorethanIP, an Altera partner, has developed a flexible Ethernet switching engine that allows designers to implement any additional function to complement the Ethernet switch and to provide connectivity to a large number of standard parts or systems with a single-chip solution. The switch can be implemented in Altera’s high-performance Stratix II family and low-cost Cyclone II family.
