It's okay. We had horrible speed before


Where the heck do china and arnold live at?! Digged a hole to the nearest university internet cable and connected to it?! WTF xD

I'm in France and the city is Caen. It's one of the few French cities that will have 100% optical fiber coverage at the end of 2016.


My upload is a bit lacking, but I can't afford any better ^^

close enough, uni isp provides internet in my dorm

Unitymedia is known for having good download but awful upload speeds as far as I'm aware.

yeah they only offer up to 20Mbit/s, and only if you buy the 65€ service w/ 400Mbit/s download...

Is it the speed connection that makes you loosing frame when you stream ?

How can we reduce to lose frame during a live stream ?

Thanks already


And how did you add a picture in your comment ?
Thanks again

  overcoolerovercooler uncapped LTE connection I have for streaming, it is like an oasis in a rural area, my ADSL just doesn't cut it. ADSL2+ for browsing, watching streams, online gayming, etc. Better than my old plan which had 0.5 upload.

I am tempted to say 186,000 miles per second, but the speed of light isn't the limitation.

Photons in a vacuum travel at the speed of light, but photons in anything else travel slower. In my ethernet cable, it's probably closer to 119,000 miles per second. The reduction in speed depends on the permittivity of the material used, so speed will be faster with fiber optics than with my ethernet cable. However, the information itself is even slower than that. At the base level, all information on computers is stored in zeroes and ones, but a single photon doesn't carry much information. On hard drives that use spinning discs (most of your computers unless you have a something solid state) is typically encoded with the change of states of the energy or the polarization of a magnet at a very specific point on that spinning disc which means that these changes can only be made at lower rates than the fundamental transmission speed and rotations per minute of the disc.

To make things more complicated, the energy and the rates of change require physical materials to convert the photons into something more usable. This is because the channel used for transmission usually conducts energy at a maximum rate called bandwidth, which is generally what is measured for network speeds because it is usually the limiting factor. This is why fiber optics can transmit signals quicker and with less loss than copper wires.

However, if we are to be accurate, we must also include the time taken to encoded and decoded when the data is transferred between different protocols (set of rules that governs the communications between computers on a network). The most well known ones are HTTP (seventh layer), IP (3rd layer), TCP (4th layer). Many different types of network protocols and standards are required to ensure that your computer can understand the computer it is communicating with. Though there are actually seven different clearly defined OSI layers, from the first layer (Ethernet) to the seventh layer (HTTP / DNS / FTP / Telnet / etc.).

There is a lot of extra data transmitted with error correction, routing information, encryption and other protocol data in addition to the raw data, though not all protocols include error-checking (live streaming, for instance, doesn't do error checking, because why would it? If something is being streamed live, if certain information is dropped, the receiving computer isn't going to go back and check it).

So. Why is a fiber optics cable faster than an ethernet cable? Glad you asked. No, I definitely heard you ask. Okay, so the short answer is that fiber optics can conduct higher energy charges, and photons with higher energies, by definition, are at higher frequencies. The energy of a photon is h ¤ f where "h" is the plank constant (6.63¤10^-34 J.s) and "f" is the frequency of the photon. What does frequency have to do with anything? Well, in general, we want to create a strong signal oscillating at the most efficient frequency for the transmission channel to conduct it. If the frequency is either too low or too high, we lose our signal's power because the medium will respond differently to different levels of energy. In material science, these values are well documented for the most commonly used materials as FmaxF and Fmin.

There all sorts of ways to add information to an oscillating wave (Tesla was a friggin genius), but in general, the amount of information you can add to an oscillating wave is proportional to either the rate the channel can respond to it or bandwidth of the system (though you still have to stay between Fmax and Fmin). Information exchange in our computers works in a similar manner to our bodies' thermoreceptors. How do we know if something is hot or cold if all nerves can do is send basic electrical signals? Well, it turns out that the brain can determine if something is "hot" or "cold" by the frequency of electrical impulses coming from a certain nerve. So let's say a thermoreceptor (the receptive portion of a sensory neuron that codes absolute and relative changes in temperature) comes into contact with something. It will send the same electrical signal to the brain in more rapid succession if the object it is touching is hotter.

As it happens, the higher the operating frequency, the easier it is to get wider bandwidths. For example, a radio at 1GHz with 10% channel width only allows for 100MHz of max switching rates, but a fiber optic signal at 500THz, a 10% channel width means a 50THz max switching rate. This is a huge difference! So why do channels have frequency limits, and why 10%? Well, 10% is just a typical example, but pretty much every transmission channel has limits to the energy levels they can absorb, reflect, and conduct. In simpler terms, an x-ray (relatively high frequency & high energy charge) goes right though a lot of materials, whereas heat (relatively lower frequency than even visible light) doesn't transmit well through paper, but it can through glass. So the moral here is that there are frequencies where photons can be used to carry energy and frequencies where they can't.

So in conclusion, yes, all photons travel at the speed of light in a vacuum, but they can't carry information at that rate. This doesn't even take into effect disruption of the signal by other signals at nearly the same wavelength and frequency. Have you ever wondered why wifi generally sucks? Well, usually, there are a bunch of routers all trying to send the same signals at the same frequency, and they are all disruption each other. In information theory, the noisy-channel coding theorem says that for any given degree of noise contamination of a communication channel, it is possible to communicate information nearly error-free up to a computable maximum rate through the channel, called the "Shannon limit".

If you've gotten this far, you're probably thinking "Hey Oddtom, since cables carry electricity moving at the speed of light, why aren't computer networks much faster?" Well let me answer that with another question: If air carries sound moving at the speed of sound, why can't I talk to you much faster? Do you see what I'm saying? If we're both in a perfectly quiet room, I can probably speak very quickly and you can still hear me, but as we get farther apart or the environment gets noisier, I'll have to speak slower and more clearly for you to understand me. In this example, the maximum speed is not due to the latency, but how quickly I can signals that you can reliably receive. In networking terms, this is limited by noise and distortions introduced by the cable. This is why fiber optics are so much better than ethernet cables, especially for long distances. It is much easier to manufacture a fiber optic cable that does not permit outside interference and introduces very little distortion, which is why fiber optic cables are usually preferred for long distance networking.


ah crap, I forgot to post my speed. Lol. I love every single one of you in the most platonic way possible.
