He didn't address peering at all, so it's possible that Comcast/VZ/ATT could still bottleneck their peering links to Google/Netflix/Amazon to reduce the amount of bandwidth their customers have access to without doing anything in 'the last mile'.
Raman amplifiers add zero latency. EDFA amplifiers add latency equivalent to the length of the fiber coil inside, which is going to be just a few microseconds.
The receive sensitivity on common '10G' DWDM optics is frequently down to -24 dBm or lower. That's less than a hundredth of a mw. So from that perspective, that +0 or +3 dBm is rocket hot. 100G optics aren't quite as sensitive, but still down to -14 or -17 or so depending on the specs.
This sort of thing is measured in dBm to make the math easier. Decibel Milliwatts, where 0 dBm = 1 mw and it's a logarithmic scale up and down from there. Individual channels are on the order of 0 to 5 dBm, or 1 to 3 mw. The composite signal coming out of an amplifier, which consists of multiple channels, is on the order of 20 dBm depending on how many channels are active and what the reach of the amplifier is. That's about 100 mw. Definitely a laser safety concern, but not military style death ray.
There are, which is why the electricity is at very high voltages to overcome it, which is why it attracts sharks. I'm more of a terrestrial guy, but if i remember correctly what they do is apply a very high + voltage on one end of the cable and a very high - voltage on the other end, and the amplifiers are powered in series inside of 'festoons' on the bottom of the ocean.
But there are still going to be amplifiers. They are referring to eliminating transponders, which we already don't use for modern sub-sea links. This is basically just 16QAM, but instead of using 4 symbols over 1 frequency, it's 2 symbols over 2 frequencies tightly spaced together. It's been understood for a while that widening the channels was probably the only way to go beyond 100gbps for a transmitter/receiver.
Multiple competing cable companies would have multiple competing outside plants. The franchise fee was always just a way for the town council to exchange monopoly status for money in the coffers.
If we catch you we sue the shit out of you. In addition to that, I'm sure plenty of other vandalism type criminal charges also apply if it's intentional.
"Radioshack never offered what the consumers really wanted a good unlocked cell phone and our choice of prepaid plans." Unlocked phones don't provide the store residual payments like selling contracts does. That's the only thing that has kept Radioshack open this long.
Just make the default password be the serial number of the device.
So I pull the serial number with an SNMP get request as part of my exploit script using a community string that is either 'public' or something standardized across the ISP? Your move.
I tend to agree with most of what you said, but you should also keep in mind how many of those millions of Muslims are sending money overseas to 'charities' that are really fronts for ISIS, Hezbollah, Al Qaeda, whatever. Certainly far more than a few hundred people. I think those communities that are funneling money to fuel radicals overseas do have some responsibility for the deaths they cause, both abroad and at home and that has to be recognized internally before it will change.
Not really. The state just sub-contracts all this out to AT&T today, although they opened the bidding up to other carriers for the 2015 upgrade discussed in the article.
This still doesn't address the real problem, when an ISP degrades traffic which competes with their other revenue streams. I.E. a cable company degrading netflix traffic or a telephone company degrading skype.
I watched it and thought it was funny. I didn't expect academy award worthy acting, just some physical comedy, dirty jokes, and special effects. It had all three and a sweet russian tank. T-54 I think.
Except that everyone is not doing this. The data collected by the big routers and voice switches can still be very incriminating to someone of a criminal or political, but I repeat myself, inclination. All of these capabilities are built into the hardware because the US government and other governments around the world requires it as part of 'lawful intercept' regulations.
If these PEOPLE know how to play it right, Node.js is history. HE/SHE had the same thing with the Mambo Fork Joomla. Hardly anyone (POSSIBLY HAVING A PENIS BUT POSSIBLY NOT) remembers Mambo anymore, and Joomla is a leading project.
I've never seen that. WAN links typically all aggregate back to the BOE/DOE headquarters in the county, or a large high school, and then there is an IP service that is also leased. The WAN links are generally 1GE or 10GE and the IP service then is provided to that location as a separate product and circuit and usually is 'right sized' to be anywhere from 250 mbps to 2-3gbps depending on the size of the county. Usually that IP service is still overkill. I'm not saying that based on "Oh that looks like way too much for a school" but "Wow these guys are peaking at 4% max utilization on that link" ellipsis ellipsis ellipsis
Actually I work for a company that specializes in rural areas. Not Alaska or Wyoming rural, but we've built fiber into schools in towns too small for a gas station. Like I said, if you fill out the right forms there is a ton of funding available.

Yes. Although more and more amplifiers are either Raman effect based or hybrid Raman/EDFA.

No, it really doesn't. 5 microseconds per kilometer of latency.

Cyaninc.com and Infinera.com products are made in the USA :)

He deserves to spend years in prison for being a pretentious asshole? That's ridiculous.

Maybe they save weight by not providing a return line?

Actually what reduced the crime was the Cosby Show. Since that show came out crime stats have gotten better and better.
