You do understand that all networks are running software today right? More importantly big networks are incredibly hard to upgrade in a timely fashion; primarily due to the problem that in most cases you have to take part of the network offline. Even in fully redundant networks the politics slow the whole upgrade process down. I look forward to the time when we can run a cluster of controllers and upgrade them in service.
A number of applications to transfer files have moved the control out of the network for various reasons. UDT, TFTP are two UDP only examples. Torrents can be UDP or TCP.
For most the people working in IT the protocol does not matter except to update filters. For those building specific applications or the networks that support those applications the understanding is often critical.
The problem with most certifications is that it is a paper test. This is a compromise to make the system easy to confirm pass / fail. The alternatives are much more expensive from a resource perspective.
The problem with the "technology" was that it did not make sense. They jacked into the bodies and controlled them half a world away without even a light speed delay. If they had progressed to mind transplant or genome modification that would allow the modification of humans it would have made more sense.
That the bodies were custom to the DNA of the individual but not to the mind was also strange.
Very small amounts of the spam is sent though the ISP mail gateway. To get a mildly accurate number the ISP would need to deep packet inspect all traffic to the standard mail gateways ports. While this is possible there is very little immediate benefit to the ISP. As the infrastructure cost is immediate most ISPs only deploy a trial to benchmark the system before abandoning the project.
I am also fairly sure that most people only glance at their bills for the amount due.
I bought Torment and played it once and never again. Thought about playing it again a few times but always had other places to spend the time. Recommended it to a few people but also told others not to bother as I could be sure they would not like it for various reasons.
Looking glass also produced Thief. The first one I played many times, the second once and the 3rd I was not able to get though at all... I bought all of them and the only one that I felt was truly worth it and recommended was the first.
So yes I felt they did not understand the market well enough... at least the Thief market as many of the people I talked with about the games had the same experience.
Wow... "Building tall buildings underground, instead of above." First, building up is much less expensive than building down. Second, having been in a bunker with false light systems... you get to miss even the small amount of natural light that you get in the center of current skyscrapers.
"Requiring high altitudes for all planes, military or civilian, and producing auto-shoot auto-aim turrets around the ciy with no warning shots." Requiring that the airport be a significant distance from any city or the planes are shot down before they get to "approved height". How far to you want to drive to the airport? It would also be putting interesting weapons around everywhere for people to play with... just imagine the first hardhack tagged story around that.
"Include parashoots as standard emergency materials for skyscrapers?" Wind around skyscrapers is very hazardous, look into wind tunnel effects that are reported around skyscrapers. Zip lines would be safer but impractical in other ways.
TCP is used for connection based traffic that needs to be retransmitted at the protocol layer when dropped. As such the TCP protocol does not require the application to maintain state as the protocol handles retransmits and flow control.
UDP is used for traffic that is connectionless where it is not necessarily desirable to have retransmits. The application handles both the flow control and retransmits.
VOIP is "real time" UDP because it makes no sense to resend a lost packet. A retransmitted packet would require more delay "jitter" in voice calls. Just skipping the missed packet is really the only option here.
The VoIP protocol has a fair amount of jitter correction built into it. Human speech also has expected pauses that people are good at adjusting to fit the phone medium. The delay going to and from the satellite compares fairly well to intercontinental calling.
Most of the core devices in carrier grade networks have an expected five year lifetime before being moved closer to the edge. May system have edge devices that were bought 10+ years ago.
Without many more details it would be impossible to judge when this would be avaialble to the average consumer.
That is not to say that you might not see an performance boost because google was able to upgrade the youtube connection.
Just to be honest here people do not follow the standards 100%. They build something that works well enough, then most add "value adds". Cisco and BGP are a good example as though they helped write the RFC they also built their code with additional features that made it incompatible in some designs. I think that Juniper built a command that allowed them to run "Cisco BGP" but its been awhile.
I don't know the number of times that I have found that system do not work the way that an RFC says they should while the company claims RFC compliance.

but degree != critical thinking so what is your point? I am tired of my HR team sending candidates with a degree but no real experience because "they have an Engineering degree".

This is why I hate English. The amount of code that would be necessary to check if "a" or "an" should be used in any instance is insane.

umm, I often do during the summer with the air running and 3 people with 2+ computers each.
have you heard of darknets?
Both have a place in the network.

Yes, If you caught them on a bad day and they decided it was something interesting to look into.
I would not expect it often but you would be surprised what trouble people will stir up when they are board.

This is already happening is at least one state. In Pennsylvania ISPs are required to block sites that are given to them by the DOJ.
