100 Gbps Via Ethernet
Doc Ruby writes, "As reported at GigaOM, 'Infinera has bonded 10 parallel 10 Gb/s channels into one logical flow while maintaining packet ordering at the receiver,' bridging 100-Gbps ethernet over 10 10-Gbps optical WAN links. Infinera's press release is here. Further from GigaOM: 'The experimental system was set up between Tampa, Florida and Houston, Texas, and back again. A 100 GbE signal was spliced into ten 10 Gb/s streams using an Infinera-proposed specification for 100GbE across multiple links. The splicing of the signal is based on a packet-reordering algorithm developed at [UC] Santa Cruz. This algorithm preserves packet order even as individual flows are striped across multiple wavelengths.' We're all going to want our share of these 100Gbps networks. The current network retailers, mainly cable and DSL dealers, still haven't brought even 10Mbps to most homes, though they're now bringing fiber to the premises to some rich/lucky customers. Are they laying fiber that will bring them to Tbps, or will that stuff clog the way to getting these speeds ourselves?" Rumors say that what runs over Verizon's FiOS is ATM, to support their aspirations for triple-play.
5 seconds at 100Gbps? How high-def is your pr0n?
How are sites slashdotted when nobody reads TFAs?
Kids! Back in my day we have to wake up at 4am in the morning to collect firewood to send out smoke signals. If you were lucky you would have 8 bits out bit by noon. And those were the good days when some script kiddie didn't try to r00t our fires. You'll take your 100GPS and like it. Now, get off my lawn!
Well, there's spam egg sausage and spam, that's not got much spam in it.
This is a natural progression of ethernet speeds. 10GigE switches are getting to the price point now that we are installing them everywhere. I even had a 10GigE switch on my home fibre for a week of testing, but slashdot just doesn't load any faster.
All the broadband providers are moving to larger pipes now, with GPON (Gigabit Passive Optical Network) going in everywhere, as consumers are clamoring for more than ADSL2+ speeds (24Mbps down, 2Mbps up) in city centres. I'm designing the back end of a GPON network, where every neighborhood gets 2.5Gig down, 1 Gig up, shared between 16 residences. Of course, there is going to be more than just internet on pipes that big, quadruple play to start, and as new services become available even more bandwidth will be needed. Once you start piling up the 10GigE connections, it will be nice to have a working trunk/etherchannel/bonding solution for those long hauls between data centres.
the AC
Hemos is like...sci-fi fans;he thinks technology is cool, but he hasn't bothered to understand the science it's based on
Well, thats closer, but I think in reality it would be a bit smaller.
/9000 * 54 = 375Mbytes of packet overhead.
So, you did 10 (Gbit/sec) * 8 (bits per byte) * 5 (seconds) = 62.5 Gbytes.
The 10Gb links are Ethernet links. Lets also assume HTTP is the transfer method, just to make it 'easy'. We could use FTP which is UDP but then we'd have to account for the TCP Control connection in the traffic. Heck, Lets even assume nice jumbo frames with a 9000 MTU. Also, lets assume the video is 'optimally' compressed.
Ethernet header = 14 bytes
IP header = 20 bytes
TCP Header = 20 bytes
14+20+20 = 54 bytes out of every 9000 transfered for header information.
On top of this, there will be HTTP headers at the start of the request, but since they are only transfered at the start (not every packet), lets factor them out as miniscule.
So, basically 62.5 is the maximum theoretical data of the circuits. 62.5Gbytes
The Maximum possible transfered in 5 seconds would be 62.5Gbytes - 375Mbytes = 62.125Gbytes.
