Teleport Media is the gate for a new level of OTT and Live Streaming. It is a customized solution for a media business to deliver media files with any type of CDN.

In this article, we discover how to deliver online video to customers with 40% less latency and 30% better quality at the same infrastructure costs and even lower in comparing to a traditional CDN. Let's have a look at impressive facts telling why Teleport Media solution is really awesome to ignore.

Teleport Media's performance during FIFA World Cup 2018 was a brilliant example. Teleport Media helped official broadcasters to cope with tremendous traffic spikes followed by streaming speed collapse and decreasing bitrate. Here are the tremendous results of this challenge:

  • 4x more sustainable than CDN
  • +37% to the quality of broadcasting
  • –40% to the streaming latency
When we encountered a peak of 1.8 million concurrent online users during FIFA WorldCup 2018, we approached the limit of our available CDN infrastructure.
Why CDN was not enough? Let's drill this question.
Content Delivery Networks

What happens when you start the live video playback on your desktop? It connects to some digital devices on the web and starts to download the stream. If the service that you're connecting is small, a single server is applied. However, global companies like YouTube or Netflix deal with hundreds of servers in different data centers all over the world. The bigger the number of viewers, the more servers they need to manage a good video delivery, and consequently, the more money these companies spend on video delivery to keep up. A group of such servers is called a Content Delivery Network or CDN.

There are many CDN providers, and video streaming businesses have an option to build their own in-house CDN or purchase CDN as a service. There are well known CDN vendors on the market such us Akamai, EdgeCast, Level3, Limelight and others.

According to a few studies stated in MordorIntelligence Industry Report, the size of the CDN market will grow from $7.3 billion in 2017 to $29.5 billion by 2023 at a CAGR of 26.1%.

On the official website, Cisco predicts that 80% of the overall Internet traffic will be video by 2021, up from 67% in 2016.

CDN is a traditional way to deliver media files. This decentralized solution is very useful and widely applied by media businesses. How does CDN streaming work? There is no streaming from one particular source, there must be a video stream divided into pieces downloading simultaneously from multiple sources into your video player. Thus, it means that CDN is the only way to do it. Ok, how about the quality and the speed, especially in terms of underestimated increase of the audience? Have a look at this below.

Limitations of traditional CDN

The main and the biggest challenge of content delivery is the ability to scale traffic delivery infrastructure in order to follow the audience growth. From a CDN's point of view on a typical day, a traffic demand looks like this:
typical viewers behaviour shown via traffic load
A small number of viewers in the morning, a steady number during the day and a spike during the evening prime time.
And this is how a day with a big event like a football game or breaking news looks like. While traffic looks almost the same as above during the whole day, the event causes a massive spike of traffic demand.
viewers behaviour during the special event with traffic load spikes
The load on the delivery infrastructure can raise 10 times in a short period of time.
The core problem associated with the streaming business is that the CDN has to maintain the capacity to deliver video to all viewers simultaneously, otherwise these viewers quickly abandon the service and switch to competitors.

Even CDN market leaders are often unable to handle peak demand, which results in a reduction of video quality or impossibility to deliver video altogether. These problems arise from a well-known fact: any infrastructure has its limits.
Teleport Media Solution

Teleport Media provides a SaaS solution for video streaming services of any kind, let's call them as customers. It acts as an additional traffic source, working side-by-side with the customer's in-house CDN or third-party CDNs to complement their streaming capacity. Teleport Media is a JavaScript which can be installed as a plugin to the video player on the customer's website, and a Software Developers Kit ("SDK") to install in their Android and iOS applications.

Teleport Media customers don't need to change their streaming solutions: the video player or media server, or current CDN. Teleport Media works as an easy to use plug-in solution on top of current streaming clients.

P2P CDN architecture
Content distributed delivery by Teleport Media
Teleport Media uses the WebRTC framework connecting several devices that are consuming the same video content at the same time. Each device in this group uploads and downloads the video content from and to other connected devices. Such a network of connected devices is often called a peer-to-peer ("P2P") network, according to Wikipedia.

By using Teleport Media, a video streaming service provider reduces the outgoing traffic from its in-house CDN and thereby reduces the need to purchase traffic from third-party CDNs. Thus, Teleport Media allows maintaining the highest video quality at any time, especially during peak hours.

Teleport Media WebRTC solution guarantees that the more audience watches the video, the more traffic is granted to the network. What was a problem — a number of viewers — becomes a solution.

Now, the rest we have to say is that Teleport Media technology is already adopted by a number of paying customers with millions of daily visitors in Russia and Canada, and now we bring our product to Asian markets.
