THE TOP: IMPACTS ON THE NETWORKS OF SMALL INTERNET ACCESS PROVIDERS

services. This work aims to evaluate, using a case study, the impacts of OTT services, specifically Netflix, Facebook and Google, on a small broadband Internet access provider. In the research, real data were monitored and collected from all clients of an ISP using the PRTG, Winbox, Wireshark, and legacy applications tools on edge routers. With the result of the case study one can have a reference for the dimensioning of internet backbone a ccess l inks with the use of CDN in the ISP environment, because users' traffic in access to OTT services in small ISP affects on average 52% of the tráfeg the total ISP.


INTRODUCTION
The Internet represents a transformative force of paradigms, making everyday situations such as how to watch movies and interact with society have a rapid transformation. As an example, television shows are structured in programming grids defined and displayed at certain times, while online video distribution platforms over the Internet, such as youtube and Netflix, deliver content through the choice of the user, interactively and in various technological devices.
Online video distribution platforms over the Internet consist of cross-platform distributed systems forming the so-called over the top -OTT. They are online services that replace traditional media and telecommunications services. It consists of a multimedia service that travels through a third-party network, in which the OTT service provider has no responsibility for the means of access to the service provided. The term OTT is used for services that have their own servers for internet distribution, some examples are: IP TV; IP radio; instant messaging, audiovisual connections; video on demand -VOD; among others. In this context is at the origin of the term OTT, in which you can navigate a site in the same way as a computer. Several devices connect without the need to be technologically similar. Examples of OTT services are shown in RC: 39487 Disponível em: https://www.nucleodoconhecimento.com.br/science-of-music/networks-of-smallinternet account for more than 70% of total mobile traffic in the region -60% last year. More than 60% of mobile traffic in Latin America and North America is encrypted. Figure 2 shows the 10 applications with the highest Internet traffic in Latin America in 2016. In this context, ISP and telecommunications operators advance in the provision of OTT services as a complement to the pay TV offering. In addition to ensuring a good user experience using solutions that increase delivery speed, such as CDN, which basically saves static content to a location closer to the user and, in some cases, can set a better path to the data network using connections to the Traffic Exchange Point -PTT. PTT is a network solution with the objective of enabling direct connection between the entities that make up the Internet, the Autonomous Systems (AS). It is a shared   Mbps for downstream traffic, with maximum value reaching 1.2 Gbps in the periods between 10:00 am to 3:00 pm and 18:00 to 11:00 pm.
The average traffic of the two links was 2.33 Gbps for total traffic and 1.84 Gbps for downstream traffic, with a maximum value reaching 2.80 Gbps. These values represent all traffic generated by clients that are not directed to the three CDNs.

FINAL CONSIDERATIONS
It's no surprise that video streaming is the best type of internet app, associated with social networks. The video continues to drive downstream bandwidth usage.
As small ISPs are directly responsible for the care of the home market in Brazil, especially in regions not assisted by large operators. They need to understand the composition of traffic (not content) so that they can build a network capable of meeting consumer quality expectations, and ensuring a good user experience using solutions that increase the speed of delivery, such as CDN.
As a result of this work it is possible to have a reference for the dimensioning of internet backbone access links via IP port and the use of CDN in the ISP or PTT environment.
The use of local CDNs in the ISP results in great savings in the hiring of links and great internet browsing experience by users.
The use of CDNs in small providers is highly relevant for the dissemination of quality Internet access, allowing the increase in internet access speed and the reduction of the values of the plans offered to customers, benefiting the population as a whole in its insertion into the Information Society.
