Comment: QoS at home vs network (Score 2) 243 243

Did you actually think that by setting the QoS on your router you were getting better end to end service??? Unless the QoS is propagated to the ISP's network and all of the devices between you, the ISP, and the destination (such as Netflix) it doesn't change a thing outside of you house. QoS on your home router prioritizes the traffic on *your HOME network*, not the carrier network. More precisely, it prioritizes the home networks contention for the WAN.

If you think that the latency issues are on your home network then why would you care what the carrier does with the traffic once it leaves you house? Seriously, I think you over estimate what QoS on your home router does. And the fact that you got a 5 insightful rating proves others don't understand either.

Oh, I work for a company that builds the transport equipment for ISPs and carriers and I can assure you that your home router does not negotiate for network bandwidth.

While the White House did not use the term "expansion" there will be additional funds applied to cover the Medicare hole. Again, I am not saying it is good or bad, merely that there is additional funding going to a government run plan. My parents are getting up in years and I don't want them to miss meds because they can't afford them either, but let's be honest, it's not there is no government run anything, even if it is just an expansion of the current system.

Well, kind of - but you have to stop reading the slanted news from Fox, MSNBC, CNN, NPR and the BBC and start going to the horse's mouth. Go to the actual proposal on and read it for yourself.

In it you will see that there is an expansion of Medicaid and Medicare (both government run insurance last I checked), a tax on those who are uninsured to cover then when they need public health care, and funding for "community health centers".

I am not commenting on whether this is good or bad (I think it has some of both) but you should know what is being proposed and to say there is nothing "government run" means you don't know what is in the proposal.

Comment: Italian justice (Score 1) 507 507

I am not sure this isn't because of the odd Italian justice system. If you want to get a better understanding of the justice system in Italy read the Monster of Florence by Douglas Preston. It is a fascinating read on a serial killer that ran wild from the 60s to the 80s.

What you will learn is that the Italian system is no where near what you would expect a civilized country to have. The prosecutor discarded the idea that it was a single serial killer killing couple and mutilating them for the notion that a Satanic cult was doing it. Anyone who tried to prove otherwise soon became accused of being part of the Satanic cult making the whole event look like the Salem Witch Trials. Preston himself got accused, even though he did not arrive in Italy until the 90s.

The worst part - the judge bought that non-sense. And as an interesting side note the same judge became involved with the Amanda Knox case (the American accused of murdering her room mate). What did they come up with in that case? That the victim died as part of "some kind of Satanic rite, with Amanda allegedly first touching Meredith with the point of a knife, then slitting her throat." It would be funny if it wasn't a court of law.

In the end it made me understand that what would never stand up in court in other western courts can happen in Italy - it just does not surprise me.

Comment: Re:Surprisingly small sounding numbers (Score 1) 136 136

The reason it is smaller than you would think is a thing called reachability. While I do not work with submarine cables I have been doing fiber optic equipment for about 20 years. From a metro perspective the numbers seem small given DWDM systems that can achieve many channels of 40G and 100G but there are limitations particularly related to distance. I really am not sure what the amps are (I would guess mostly EDFAs and RAMAN amps plus some back to back amps for regen to clean the signal up) but the higher the speeds the shorter the distance and more amps are needed. All of this adds complexity in an inhospitable environment and greatly adds to the cost.

If anything surprises me about this article is the cost - $300 million seems a bit cheap for the fiber (in an armored submarine cable), transmission equipment, and labor to lay a 10,000 km cable.

I have the same printer and am likewise impressed. Someone earlier said that the construction on brother was poor - not that I have seen with this printer. I too was looking for color that would not dry out and have been very happy with the 4040CDN. It prints out of the box from windows and linux. The only downside is the printer reports "out of toner" long before it really is. Google and you will find the steps to reset the counter and you can buy the tone to refill online very cheaply. Networked color laser duplexing for less than $300 - hard to beat.

Again by the ITU-T G.709 standard an OC192 WAN PHY and LAN Phy can be transported in an OTU2 (OCH 107). This has a payload (+OPU) of 9.9953G. To get true wire speed 10G you have to use an OTU2e (OCH 111, also called transparent mode) which has a payload +OPU of 10.3125. FWIW, there is also an FC standard OTU2f (OCH 113) which has a rate of 10.51875G. I keep these numbers on a chart I made on my wall - too much to memorize :-)

Well, not exactly. Yes, it is true that OC768 is in the 40G range but that is not the full story. 40G signals are carried over DWDM systems using digital wrappers (all of this is based on the ITU-T G.709 standard). So an OC768 is carried in an OTU3 (OCH430) wrapper. But if you want to carried a 40GE signal is can be carried in an OTU3e1 (OCH445). Yes, I know this is an extension of the current OTU standard but my point is that the speed of Ethernet is not really bound by SONET as most of the transport is over DWDM systems, not MSPP SONET/SDH systems. It is carried digitally wrapped over DWDM ROADM systems.

Oh, and yes, I am currently working w/ 40G systems and soon 100G.

No, other companies can not use the fiber like they can the copper - and that is the point. In 2004 the FCC ruled the RBOCs (incumbent telcos) were required to continue selling copper access to CLEC (Competitors) under Section 271 of the Telecommunications Act of 1996 BUT removed the requirements for fiber. This was done to encourage the RBOCs to make the huge investment in the fiber infrastructure. There was a lot of debate about this at the time and I think, being in the business for years, this was a good decision otherwise I can assure you there would be NO FTTP (fiber to the premises) in this country. But the cutting of the copper is out and out dirty pool.

Now CLECs have no alternative to delivery as there is no copper and they can't use the fiber. Do you think VZ knew this? Uh, yeah...

Personally I think that if the RBOC has cut the copper line they should be required to repair it for the CLEC - at thier cost - period. It seems the only fair course.
