| Message-ID | <rb388s$ol1$1@dont-email.me> |
I need a low-latency connection to a colleague in the same city (Kingston Ont.) but who has a different ISP. I've traced the route of packets and they go via Toronto, Chicago, Buffalo, and finally back to Kingston (!). I've asked tech support for my ISP and they say they can't do anything about this. Is there anything I can do on my system, such as routing packets directly to the final destination or to the Buffalo site?

Toronto,Canada is on the west end of the north shore of the same lake. Chicago is at the bottom of Lake Michigan in the USA. Buffalo is at the west end of Lake Eire. Getting fro Buffalo to Kingston goes through Toronto. So his complaint is that a 10 km trip is making the packet go on a 1000km trip. Mind you since a packet can circle the whole earth in 1/7 of a second,a 1000 km trip is not too bad. Actually it is possible that that packet actually made a 35000 km trip up to one of the geosynchronous sattelites and back again but then again that would imply about a 1 second round trip.

Most of the delay is not caused by distance, but by the number of
machines that process each package. Basically the number of routers.

Basically the number of routers. Most of the sattelite delay is speed of light. They are far away if geosynchronous. On land I agree that the routers, etc can be a significant delay. esp for distances of a few to a hundred km. For thousands of km speed of light again becomes the problem. A ping to the UK from Vancouver is about 140ms, which is about c/2.5 for the round trip great circle distance. (c=vel light) >

The video is kind of two parts: in the first 10 minutes, they fail to establish a link, mainly because of poor planning. In the final ten minutes, they do a much better job of linking a 12 Km distance, between a high-rise residence and a park. This may give you an idea of what is involved. https://www.youtube.com/watch?v=lYJFwXw1ZIc -- Ken Hart kwhart1@frontier.com

Here in Norway, only small outlying villages still have analogue telephone lines, and most of these are being disbanded. In my town (about 1000 households) we have had fibre for internet, TV and telephone (for those, like us, that still have a "house" telephone and not just mobiles) for about a decade.

Most people have switched to voip phones that work over internet connections, but land lines are still available. Costs more, but it still works if the power is out, which is not true for the voip phones. With a voip phone it's pretty hard to call for support for electrical or internet disruptions. I'm in London, Ontario, Canada, so like the OP in Kingston, within Bell Canada territory. Regards, Dave Hodgins -- Change dwhodgins@nomail.afraid.org to davidwhodgins@teksavvy.com for email replies.

Mobile phones dominate here - a lot of households don't even have a "house" telephone any more.

The mobile phone network is more vulnerable to power failures than the
POTS. The weak point is that the towers have only batteries for backup,
which may last a day or less.
And of course, you may not have charge on your own phone.

If you have a power cut that will knock out the towers for a day, it will knock out the POTS system too - the POTS exchanges take power to run and have batteries too. Add to that, a large number of POTS telephones have local power - such as for cordless telephones. It's been decades since I've used a home telephone that didn't need a power supply. And in thunderstorms, it's the POTS telephones that are at risk - mobiles are fine, as are VOIP with fibre internet. > > And of course, you may not have charge on your own phone. > Most people are so addicted to their mobiles that they /always/ have charge on them - and probably have an external battery for emergency charging. And you can charge them from your car, your laptop, or many other places. Maybe I'm just lucky in living in a place where mobiles, internet, VOIP and power are all extremely reliable.

False, that POTS will not be knocked out in a day. I've experienced 3 or 4 day power cuts due to storms, and the pots continued to work. The local exchanges all have generators backing up their short term battery backups. > Add to that, a large number of POTS telephones have local power - such > as for cordless telephones.

While that's true, In the 75 years this house has had a land line, there was only once where the lightning arrestors had to be replaced. The phone still worked after the strike (which destroyed two desktop system motherboards), and the electrical transformer on the pole across the street, but the phone line had a lot of static till the graphite plugs that work as arrestors were replaced. > And in thunderstorms, it's the POTS telephones that are at risk - > mobiles are fine, as are VOIP with fibre internet. That's true, but the risk is extremely low. There have been people electrocuted by land lines being hit by lightning, just as there have been while having showers, but both occurrences have been very rare. Much lower risk than the risk of being hit by a car crossing a busy street. >> And of course, you may not have charge on your own phone. > Most people are so addicted to their mobiles that they /always/ have > charge on them - and probably have an external battery for emergency > charging.

The power will go out just as re-charging of the phone is about to be started. :-) Very few (if any) of the people I know have an external battery for phone charging. > Maybe I'm just lucky in living in a place where mobiles, internet, VOIP > and power are all extremely reliable. It's much more reliable now than it used to be. Winter's have been much less severe than they were prior to 1980. Thunderstorms are more common, but multi day blizzards or ice storms just don't seem to happen anymore. https://en.wikipedia.org/wiki/Eastern_Canadian_blizzard_of_March_1971 https://en.wikipedia.org/wiki/Blizzard_of_1977 When the snow plows are pulled out of service due to visibility being less than the distance from their windshields to the plow blade, and that lasts for days, that is truly forced social isolation. With the power out, the only working communication was battery powered radios and pots telephone lines. There have been many others that were less severe or long lasting, but those two stand out in in memory. :-) Regards, Dave Hodgins -- Change dwhodgins@nomail.afraid.org to davidwhodgins@teksavvy.com for email replies.

True, but these are normally huge, and are backed by diesel generators over here, so that they can last for weeks. > > Add to that, a large number of POTS telephones have local power - such > as for cordless telephones.

The laptop may be needed otherwise to access some webpages to request services :-P > Maybe I'm just lucky in living in a place where mobiles, internet, VOIP > and power are all extremely reliable. I had the gadget that converts the fibre to ethernet fail completely about 6 months ago, so no service at all during a weekend, compounded with the impossibility to reach a human at the help phone for the company. I had to use the webforum to contact them - using the mobile phone to give internet to my laptop. Then they replaced the gadget. Then, during the confinement because of covid-19, the box that gives TV service crashed and produced a broken image. I thought it needed replacement, something practically impossible with the confinement rules here. Fortunately, they managed to upload new firmware remotely and get it working again, but it took about a week. Again, contacting them via webforum. The router does hang now and then. I have a setup to do a power cycle with a watchdog. I have had internet fail completely some evenings. Sometimes the failure is regional and goes on the news. TV may stop working while I watch something in the early hours, the thing reboots remotely. At another place, electricity failed each evening randomly for some time, half an hour or so. I have a cute photo of the laptop illuminated by a kerosene lamp. -- Cheers, Carlos.

Central Offices (POTS) have generators.. Most cell towers do, but not all of them.. A lot of the older ones simply have twenty 12v batteries (AT&T / Verizon / etc) The primary Central Office for San Diego has a 1 megawatt generator (for example).. I have NEVER had a landline go down because of a power failure. Not once.

Not once. Neither did we, until we went to fiber. Recently we had a day-long scheduled power outage so Hydro could upgrade the lines. I was going to dig out my old line-powered phone and make regular checks on the phone line, but I got busy with other things and forgot until about four hours into the outage. At that time I plugged the phone in and tried it. No dial tone. Apparently the backup battery for the fiber interface lasts less than four hours... -- /~\ Charlie Gibbs | Microsoft is a dictatorship. \ / <cgibbs@kltpzyxm.invalid> | Apple is a cult.

I used to build those.. Four 170 amp hour 12v AGM batteries in series for 48V... That's it.. 170 amp hours of 48v.. If you had a fiber connection from the cable company, I have no idea what they use for backup power, as I never worked for them.

I don't have, need, or want one. Due to health problems I rarely leave my house, so a mobile phone is just a waste of money. While a majority of new phones in the last decade or so have been mobile ones, land lines are still an option, and many houses still have one. While I started working as a programmer in 1979, many of the people over 50 (I'm 59) who own their own homes are not computer literate, and choose to stay with their reliable land line telephones.

My wife and I both have mobiles (mine is a good old flip phone), but I use mine primarily for text messages. We still have our land line and have no intention of giving it up. One thing nobody has mentioned yet here is that the sound quality of cell phones can be truly dreadful. There's often some sort of continual phase shifting distortion to which I'm extremely sensitve. Apparently this doesn't bother most people, or there'd be an outcry to move to better codecs and less jitter. But I guess that's just me being a curmudegeon again... -- /~\ Charlie Gibbs | Microsoft is a dictatorship. \ / <cgibbs@kltpzyxm.invalid> | Apple is a cult.
