Content Delivery Network (CDN): What it is, what it is for and why it does not break with the Neutrality of the Net |
Posted: May 27, 2018 |
Surely, many of you do not sound at all this acronym, since it is a term that usually do not handle end users, but operators and large companies. Therefore, we will try to explain in a summarized way what these CDNs are, what they are for and why, in principle, they should not break with the Neutrality of the Net. What is a CDN and what is it used for? A CDN or Content Distribution Network is basically a set of servers located in different points of a network that contain local copies of certain contents (videos, images, music, documents, etc.) that are stored in other servers generally geographically distant, so that it is possible to serve these contents more efficiently. This improvement in efficiency is achieved with a better balance of the load to which both the servers that host the contents and the links that interconnect the different sections of the network are subject, eliminating possible bottlenecks and serving the data according to the the geographical proximity of the end user. That is, in these CDNs the contents are replicated in different networks and countries, directing the requests of the users to the copies closest to their network. This prevents some servers from collapsing due to excessive requests, thanks to the geographical distribution of the data, and delays are minimized, since the path to the content is the minimum possible. CDNs and their possible influence on Net Neutrality This type of networks are not a new invention of Telefónica, but have been used for quite some time, as for example is the case of Akamai. The usual until recently has been that this system of local content replication is limited primarily to static data from a website such as images or documents, although in normal times it is focused on other services, such as streaming Of video. The question that comes immediately to us with regard to these Content Distribution Networks is if they are in any way aware of the Net Neutrality. In principle, the CDNs should not go against the neutrality of the Network, since what is involved is to bring the contents to the user to improve the speed of access. It is a business model in which theoretically all parties involved win. The operator collects new and juicy revenues from companies interested in this service, avoids having to pay other operators for part of the traffic that goes outside their domains and theoretically earns in customer satisfaction. Content companies improve their service and end customers improve their user experience. The possible problem of the violation of Neutrality that many fear could come from hypothetical limitations that the operator could impose on large companies that encourage the use of the Net, such as YouTube or Netflix, coercing them indirectly to contract their local storage services if They want to be able to give a good service to their customers. How could they exercise this coercion without infringing Net Neutrality? Well, very simple, limiting the capacity of their connections with other networks (either technically or by reduction in future investment), so that the saturation of these would be practically constant, being the CDNs of the operator the only "saviors" of the users. The benefits of CDN services: When choosing different CDN options, people strive to make their content move faster towards the end user. The main benefits of such solutions are obvious - people are more likely to stay on your projects’ pages for much longer times and to come more often to them when your website, for example, loads as fast as it should load and they don’t have to wait for half a minute. CDN allows this to come true due to the fact that all static content that is usually the most heavy part of any website, is loaded from the CDN server that is closest to the users. This means that the latency of such transfer is reduced significantly. The faster your website loads, the higher is its rank in the search engine results. This is a rule that is known by everybody. Of course, nobody knows exact rules that are used by search engines, because they are kept in a secret, but they do not hide the fact that speed matters. Such solution also helps to decrease load from your main server and distribute it across multiple CDN servers.
