Undoubtedly, Ethernet is the most widely used interconnect technology in computer networks. For the past 33 years, Ethernet performance has advanced from a 10 Mbps technology to today’s 10 Gbps solution. With the expected introduction of unshielded twisted pair interconnect in the 10 Gbps Ethernet (10GE) standard, 10GE will become more affordable and attractive as a high-performance solution in embedded systems.

The high data rate of 10GE results in a large disparity between the network data rate and processor performance. You could argue that it requires a 20 GHz processor to handle the TCP/IP traffic over one full duplex 10GE link. This performance gap results in blocking the full
10GE throughput.
