    Bob Metcalfe says INFN is leading the way to faster network speeds

    Gigafying the Internet - By Bob Metcalfe

    Build it and they will come, or at least they have for faster Ethernets since 1973. We are celebrating Ethernet’s 40th birthday at the Computer History Museum on May 22 & 23 in Mountain View, California, not far from Infinera.

    Our first Ethernet at Xerox PARC in 1973 ran at 2.94Mbps, about 10,000 times faster than the 300-baud acoustic modems then connecting our ASCII terminals with the Internet, then still called Arpanet. That first Ethernet was also quite a bit faster than the transcontinental trunks of the Internet’s backbone, which ran at … 50kbps. A lot of people asked if an increase in bandwidth by 10,000 times was justified by what was needed. Of course, with Ethernets, new things were needed. We started with Telnet, then email, then The World Wide Web … and now YouTube. What next?

    In 1980 we introduced 10Mbps Ethernet as an IEEE standard. “Overkill!” they grumbled. Then in the 1990s came 100Mbps Ethernet. Then 1Gbps Ethernet. Then 10Gbps. Now 40Gbps, 100Gbps, and 400Gbps starting standardization at IEEE 802.3. Each time some wags asked whether we had reached the point of diminishing returns. Each time, so far, not nearly.

    Onward to Terabit Ethernet!

    We're now starting work on “gigafying” the Internet. I have a hunch that Infinera will be leading the effort.
