Amazon and you

It was news to me that Amazon and M'soft data centers are adopting SDN. I'd love to hear any details on that...or opinions on whether SDN ever moves beyond the really big data centers.

Why are surpised Rick?...the whole concept of SDN is to lower the networking cost and get free of expensive Cisco boxes...I would expect Amazon to be the first to jump on this concept...with Google, Facebook etc quickly to follow...in my view in 5 years the whole market will move over, at least in new purchases...Kris

It will take a lot for SDN to move well beyond big data centers. There needs to be an opportunity as well as a motive for doing so. It is a good sign that Amazon and Microsoft are adopting SDN, however. It shows that broader adoption is possible.

the motive is simple, price...why buy a box from Cisco if you can buy SDN box for 1/10 of the cost?...that is why the overall networking hardware revenue is descreasing and Cisco stock suffering (and others who produce high end equipment, Cisco is just an example as they are still number 1)

...networking specialist brother or sister please help me out with this one?

"The future of the network is Ethernet, x86, and OpenFlow -- nothing is controlled by a single party, it's all community based."

Thanks.

so what is exactly the question? I think he is merely implying that there will be no central authority to decide where your IP packet goes...that at least is the OpenFlow part of that sentence

the question may be whether a central authority is necessary to decide such things at all.

That helps, thanks, because we've already got Ethernet and x86.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
