IEEE Launches 400G Ethernet Standards Process 94

Posted by timothy from the just-go-straight-to-800 dept.
alphadogg writes "The IEEE this week launched a study group to explore development of a 400Gbps Ethernet standard to support booming demand for network bandwidth. Networks will need to support 58% compound annual growth rates in bandwidth on average, the IEEE claims, driven by simultaneous increases in users, access methodologies, access rates and services such as video on demand and social media. Networks would need to support capacity requirements of 1 terabit per second in 2015 and 10 terabit per second by 2020 if current trends continue, the organization says."

        It also remains to be seen whether the IEEE wants to go after some of the non-ethernet interconnects with this one, to try to get ethernet into use for larger-than-single-chassis interconnection of things that are usually confined to single boxes and 'internal' busses.

        Your end user probably doesn't even need 1GbE; but his boring cheapo desktop probably has an 8(if 2.0) or 16(if 3.0) GB/s PCIe connector available for adding a graphics card. Hypertransport or QPI are faster still.

        If one had the desires of people building larger-scale closely interconnected systems in mind, a very, very, very fast flavor of ethernet(with convenient ethernet features not generally available on internal busses, like the more sophisticated switching and routing capabilities); but enough speed to serve as an interconnect for a rack full of blade modules with virtualized storage and networking, or NUMA across all blades, or both, could be quite handy.

        Such features have been available for a while in proprietary busses from the very expensive supercomputer outfits; but the IEEE may be looking to move in to that area with at least certain flavors of ethernet....

        An HD video can be quite large. You start getting many people downloading or streaming them, and pretty soon you are going to need huge bandwidth.

        With 50mbps and 100mbps internet plans readily available you'd need gigabit at least to avoid the internet slowing down your network or vice versa.

    • This is for enterprise and ISPs. Most of the equipment that uses this kind of bandwidth just splits it up and sends it on its way. Imagine the trunks that connect ATT to Sprint... They aren't going anything with the data but routing it. Check out this switch, and it's an old one: http://www.tech.proact.co.uk/foundry/foundry_bigiron_rx16_switch.htm [proact.co.uk]

      I don't think you really considered the growth of information that is accessible now. In the mid or late 90s, we were still paying by check (and getting cancelled checks back!) - now we can take a picture of the check with our phone and deposit it that way.

      • Fax machines are still used in some fields because their acceptance as legally-binding copies of signed contracts has already been tested in the courts and case law / precedents already established. This has not yet occurred for "electronic signatures" [wikipedia.org], so the legal validity of electronically signed contracts is not as well established in courts of law, at least in the USA.

        You generally have no choice of water companies. Asking "how big are your water pipes" is silly because you never had a choice of pipes, so it never mattered, and you never had a choice of pipe providers. If the water companies were all for-profit and there was some (limited) competition and not only was it metered, but you had to pay pipe rental based on your diameter, then yes, people would know their pipe size and discuss it with others, and compare in the marketplace.

I haven't seen any home equipment that uses 10 Gb yet, and even if it did, the rest of a home machine couldn't push bits that fast. And with a 10 Mb Internet, it doesn't do me any good. 1Gb will be about all we'll see in the home for a while, and that's good enough for any current use.
