Good day everyone. That's before visiting Okled what happens on December 9, I decided to write a post and gather some opinions. I must say that my work is connected with the network technology in the biggest provider statistik austria Russia - Rostelecom. Let's start a little research: 1. Bandwidth consumption (the Internet) throughout the Russian Federation certainly hesitate, but at the peak composes 0.5Tera bps. Simple calculations statistik austria lead us to the fact that it is five (5) 100Gigabitnyh interfaces. Let me remind you that this is the entire population of the Russian Federation, according to the latest census that about 143 548 980 (estimate for 2013 - wiki) 2. Simple statistik austria search looking map network of submarine cables. This is convenient because you can find there and the companies that they rule them, and see what services they provide. For example go to the Submarine Cable Map and look for NC. That's like one of the firms - SubPartners - APX East. Revered and see what is offered connectivity statistik austria 100Gbit per second. From there you can see that the capacity of the cable - 19.2Tera bits per second that can be assumed as a spectacular lot (look for the RF point one). Just do not forget that these cables (not exactly the same, but close to it) not one but vskidku 4. 3. Simple relation kollichestva Russian population to the population of NC (Population clock - Statistics New Zealand 4,486,017 people) ~ 32 times. That is just the interface 100Gbit second dozhno enough for the whole country, and even with a decent margin! 4. Prshu also be noted that in Russia it is very difficult to find a rate that would have been just limited traffic. Almost all - the speed limit. So why am I all the above should be incomprehensible to me dominance tariff plans with limited quota. Now consider the connectivity technologies that exist now in NZ and that seems to me this should be. And as my conclusions. Immediately statistik austria that we are talking about big cities, or at least very large settlements. 1. The basic technology of connecting users in NZ is ADSL (and its variations are not including VDSL2). The price of this question is not clear to me. Telephone lines existed long (relatively) before the arrival of Internet providers. The cost of say $ 100 to NL (max speed standard up to 12Mbps per second to the subscriber) for equipment that is already there (put DSLAMy and hold them until the connection is not so hard) I do not seem to be justified. That's a lot. Very. 2. Second tehnalogiya VDSL2. statistik austria We will not talk about it too much, just note that the speed of large (up to 200Mbit per second in total in both directions), but the technology is very much depend on the distance. At half a kilometer it is 100Mb per second in both directions, 1 km 50MB at 1.5 and no longer as a normal ADSL. How otstupenie at short distances, statistik austria which is not uncommon in the NT, many users could have a "normal" connection speed. The above technologies have in my opinion, by modern standards huge disadvantages. Tahnologiya Number 2, by definition, can not be mass due to problems with distance. Technology for number 1 speed too small (they can only tolerate faute de mieux). statistik austria It's like comparing statistik austria against modems ADSL, ADSL and now against the more modern technology. Now we come to the modern (again relatively) technologies applied to NC connection as I see it. All modern optics connection is now (its various forms) and radio (its various forms). Consider statistik austria a little more. Let's statistik austria start with optics. For NC helpful and correct choices seem to me the following: statistik austria 1. FTTx (in this case, FTTB (Fiber To The Building)). With this method of connection in each building is a single fiber, which implies a speed of 1 Gb per second and up to 100GB seconds without problems. This technology, as well as throughout the world, used to connect to home (not that the family lives in MDM), which can accommodate many people. I estimate say 20 people and up to infinity. For NC is the perfect option for such center. Distances are small, big house, statistik austria the presence of cables and point the main exchange nodes as well have. Because of the small kollichestva houses, it seems to me, this connection scheme is ideal and had life
