Multipath TCP Introduces Security Blind Spot

Shatrat Re:Design Issue (54 comments)

What's to stop it from using only the 4G connection and being completely undetectable by the firewall/IDS/IPS? That scenario is already broken.

'Optical fibre' Made Out Of Thin Air

Shatrat Short and straight only? (1 comments)

I'm having a hard time seeing any communication use for this. Surely the range is going to be very limited and it can only fire in a straight line. If that's the case I'm not sure what the benefit is over just firing a laser straight at the receiver.
Air does have a lower refractive index than glass which has latency benefits, but 'Hollow Core' fiber is in development which would provide the lower latency without requiring line of sight.

Alcatel-Lucent's XG-FAST Pushes 10,000Mbps Over Copper Phone Lines

Shatrat Re:Meanwhile, in DSL-land (149 comments)

It's true a lot of FTTH early adopters didn't find the business model as attractive as they thought. But every year the price of the FTTH PON equipent comes down, and the price of ADSL and copper is going up.
It's inevitable that we will all have FTTH at some point. It's debatable whether the existing ILEC will survive long enough to build all the way to the home, but I think the healthier ones will.

Alcatel-Lucent's XG-FAST Pushes 10,000Mbps Over Copper Phone Lines

Shatrat Re:However this begs the question.... (149 comments)

20 milliseconds to what? Google? That's going to be dependent entirely on the ISPs transport network and peering locations, and the access technology won't affect it at all (assuming it's not congested).
The latency from the customer to the broadband gateway router in the ISPs office is going to be similar to a LAN.

Alcatel-Lucent's XG-FAST Pushes 10,000Mbps Over Copper Phone Lines

Shatrat Re:Why not use Gbps? (149 comments)

Maybe to disambiguate from 10GigE, which is a different beast altogether from 10G over unshielded telco twisted pairs.

Alcatel-Lucent's XG-FAST Pushes 10,000Mbps Over Copper Phone Lines

Shatrat Re:30m (149 comments)

The other concern is, what if only 1 or 2 tenants in the 10 story office building are interested in anything higher than 50mb/s service. Why run fiber through the whole building for those two customers, when you can just upgrade your equipment in the wire closet and be done in an afternoon?

Shatrat Re:Meanwhile, in DSL-land (149 comments)

Synchronous != Symmetrical. The article does mention that the XG-FAST technology is symmetrical, although the service provided by the Telco probably would not be.

Alcatel-Lucent's XG-FAST Pushes 10,000Mbps Over Copper Phone Lines

Shatrat Re:Meanwhile, in DSL-land (149 comments)

This is the future of DSL land. Every year the twisted-pair based providers build more fiber extending their DSL aggregation modules closer to the customer. Eventually they will all become FTTH providers, but somewhere in-between they are high speed DSL over short copper lines that go to a DSLAM at the end of the street.

Alcatel-Lucent's XG-FAST Pushes 10,000Mbps Over Copper Phone Lines

Shatrat Re:30m (149 comments)

This is a good way to get high speeds into multi-tenant buildings. You bring fiber into the wire closet and then run this over the existing copper to the offices, apartments, suites throughout the building.

To what, the DSLAM? A few microseconds. To the IP drain? The same as before. Also, this does not beg the question.

White House May Name Patent Reform Opponent As New Head of Patent Office

Google, Detroit Split On Autonomous Cars

Shatrat Re:Detroit calls Google arrogant? (236 comments)

Is this a republicans vs democrats thread in disguise? Just because one side of the discussion is arrogant doesn't mean the other is not. Google has a long history of failed projects because they're not afraid to over promise and blindly charge into a project. I think the ignition recall is a good illustration that the automotive industry doesn't have that luxury. My Google TV appliance, which is now an abandoned project, isn't going to kill me. An abandoned self driving car project might, even if it's not my car.

Robert McMillen: What Everyone Gets Wrong In the Debate Over Net Neutrality

Shatrat Re:IANA Network Engineer, but... (270 comments)

So better performance and lower costs are not a benefit to the ISP and its customers? I'm not speculating here, just yesterday we deferred a project costing $300,000 because installing a Netflix OpenConnect cache dropped our peak bandwidth usage enough in the market in question that we can afford to wait. Now we can wait a few months, maybe to 2015 and spend that money on other projects.

Half of Germany's Power Supplied By Solar, Briefly

Shatrat Re:After Fukushima? (461 comments)

It's meant a little more solar and a lot more coal. Fear of the unknown has led to more pollution.

Robert McMillen: What Everyone Gets Wrong In the Debate Over Net Neutrality

Shatrat Re:IANA Network Engineer, but... (270 comments)

I'm speaking from experience here. I've seen the drop in peak bandwidth before and after deploying these. We spend hundreds of millions a year upgrading our network, so a free box that eases the pain is an easy call to make.
Netflix provides the appliance for free. The space and power costs are pathetically small compared to the benefits in increased quality and decreased expense and capital upgrades.
Also, they didn't offer this only to Comcast. They offer this to every ISP, see the link below.

Robert McMillen: What Everyone Gets Wrong In the Debate Over Net Neutrality

Shatrat Re:IANA Network Engineer, but... (270 comments)

What cost? Space and power? Installing a caching appliance will save thousands of dollars per year, maybe per month, for any ISP of any significant size. So, maybe an extra $10 a month on the electrical bill is balanced against better service to your customers and reduced network expenses, and the capital cost to upgrade routers and transport.
This is a no-brainer for any ISP concerned with providing service, rather than 'monetizing' their customers.

Comcast plays ball with Google because if they impair Google then Comcast's large enterprise customers will raise hell. They can get away with squeezing Netflix because nobody uses Netflix at work.
