Questions regarding Internet at work.

Kareem

Hey everybody. I got some questions that always come to my mind.

I am at work now. From what I know that Lebanese ISP are all almost the same and Ogero is so far the best.

I did not work for any ISP before so I do not have a good knowledge of the Lebanese infrastructure. From what I know, is that Ogero main link is an old one connected to USA.

Now performing some ICMP pings, I see that reply on most website ie: google, yahoo, microsoft, apple... is no more than 55ms as if I was in Europe. Latency here is incredibly low. For online games it's like 50-80ms.

Even if this is a corporate 10mbps connection, shouldn't the lag be around 150-200ms ?

Maybe nuclearcat or teodorgeorgiev can answer as they have worked for ISPs before.

from personal experience when there is no pressure on the networks wherever you are in Lebanon you get good latency :) even on a 256/kbs connection you can get 150-250 depending on the server and how you are routed to it physically regarding distance and number of switches and hubs on the way to the destination(gaming/web server) and vise versa :)

rolf

Yes, 50ms is incredibly low.
Maybe you got lucky and put on a new super fast link.
It is also possible that someone somehow programmed a firewall somewhere to spoof ping replies (never heard of this, but its technically possible), or maybe also its a DNS trick to redirect you to a proxy. Check if the IPs are correct. Or maybe the aliens abducted you and you are living in a virtual world.
But if you work at Nokia Siemens, then your company most probably got special treatment (didnt they do part of the GSM network infrastructure?) and got a fast access to the backbone.

MR NSN,

you are running on a private line, a dedicated bandwidth which is interconnected to the world differently in comparison to the home adsl connections.

do your traceroute and you should notice a different path for your trace in comparison to other ogero homeuser path traces..

Hey Bashlogic, yeah I thought so, but should'nt all connections in Lebanon pass through Ogero? and the trace route results showed me that I can get directly connected to Europe without passing by US links. I thought also Ogero has only 1 major link to the US as the EU one was shut down due to finacial problems.

btw shu ossit MR NSN ? :)

kareem perhaps your conection has nothing to do with ogero ? have you thought about that ? perhaps you have a sattelite uplink ? check about that :) , just for a test when you open google ? in what language does it want to be ? :P

J4D

nsn = nokia Siemens network

Well afaik Ogero's links are not passing through the US anymore. I have been getting a direct connection to Europe since like... 7-8 months now.

The lowest you could get on an ICMP packet is 117ms on the home ADSL (512K) but I am not sure how low it could get on 1M+ and if there is any difference at all.

Like rolf said, 55ms is amazingly low which gives me reasons to believe it's not going through Ogero at all.

@rolf, why would someone waste their time spoofing ping replies or implementing something for that matter?

@Flyingwizard: MOST probably :) @kareem : look try speedtest.net it automatically tells you your isp , so try it and tell us :D

argh.. back to basics, I cant believe that im explaining this to Mr NSN.

lets take it by layers
you have your IP connectivity
you have your subscription links
you have your backbone which could be just about whatever.
you have your carrier connections.

each layer has its own mesh routing connection. if ogero is delivering your connection, it does not mean that they are providing you with the IP addresses nor ip connectivity. ogero could be providing the underlaying carrier connectivity where they have nothing to do with ip connectivity for example they could be providing the physical connection, the backbone connection and connectivity to the carrier. hence that is what i was reffering to when i told you to look at the traceroute. the only way you can see the "real" physical route is by getting your hands on the router and tracing your carrier path from there.

@ bashlogic : that's totally correct but i guess let him try speedtest.net first and he can easily find his ISP as well as the ISP's IP :) kareem once you get your isp name give it to us so we can do our research :P

speedtest can be foolled,

J4D

come on ! it can be fooled but that's not necessarily its fooled at all times :lol: ;)

jadberro wroteperhaps you have a satellite uplink ? check about that :)

geostationary satellites are at around 35000 km
speed of light is around 300 000 km/s

1 way to satellite --> 35000 km
2 ways (earth --> satellite --> earth) --> 70 000 km
if your packet travels at the speed of light on your satellite link (which it definitely does not, not even close to it), it needs 0.23 sec, that's 230ms...
no way to reach anything even close to 300ms on a satellite link, so don't dream of 50ms on a satellite link, not now, not in a 1000 years...

err the last time i checked, SATELITES mostly work by RADIO Waves and not LIGHT Waves...

300,000 / 70,000 = 4.2857142857142857142857142857143 ms ;)

ill try and search the speed of the sattelite uplink but i can assure you what you have said is wrong :) :P

BashLogic wroteerr the last time i checked, SATELITES mostly work by RADIO Waves and not LIGHT Waves...

that's why i said this:

if your packet travels at the speed of light on your satellite link (which it definitely does not, not even close to it),

what is said in the parentheses didn't come out of nowhere...
i just took the best ever possible scenario physically possible.

it's 70 000/300 000, not the other way around, and the answer will be in seconds...
not only u got the division wrong, but also your units are all wrong. u divided km/s by km and you got an answer in ms...

J4D

the 70,000 is the variable why do i have to devise it on the speed of light LOOL and i thought i suck at maths and critical thinking :P

battikh

300 000 km ---> 1sec
70 000 km ---> x sec
x = 70 000 * 1 / 300 000 (and the unit is sec, not msec, unless you do the proper conversion)

that's regle de 3, you should have learned this in 6eme dude...
makes it clear who's bad in math and critical thinking...

and how is 70000 a variable? the satellites altitude keeps changing?
