How Both Media Businesses And CDN Providers May Benefit From Teleport Media Solution

In this article, we aim to find out the difference between the regular CDN operation and how does Teleport Media empower the existing CDN technologies.

Teleport Media WebRTC Live Streaming is made for media businesses of all kinds to improve the quality and speed of traffic delivery, but also to accelerate existing CDN capabilities being applied by CDN companies.

As a matter of fact, a content delivery network (CDN) was invented as web and media content centralized delivery system. A person or a company willing to deliver media files or stream video into the web had to use free or commercial CDN or create one itself since there was no other way to provide users with the fastest possible experience until decentralized CDN solution was introduced.

Regular CDN features

Let's have a look at traditional CDN first. In simple words, CDN is a geographically distributed network of proxy servers and their data centers. Its goal is to distribute service spatially relative to end-users to provide high availability and high performance. CDNs serve a large part of the Internet content today, including web objects (text, graphics, and scripts), downloadable objects (media files, software, documents), applications (e-commerce, portals), live streaming media, on-demand streaming media, and social media sites.

In the internet ecosystem CDNs play the role of a medium. Different content owners pay CDN operators to deliver their content to the end users. In return, a CDN pays ISPs, carriers, and network operators for hosting its servers in their data centers. The process looks simple and operates with a huge amount of hardware all over the world.

CDN nodes are usually deployed in multiple locations, often over multiple backbones. Benefits include reducing bandwidth costs, improving page load times, or increasing the global availability of content. The number of nodes and servers making up a CDN varies, depending on the architecture, some reaching thousands of nodes with tens of thousands of servers on many remote points of presence (PoPs). Others build a global network and have a small number of geographical PoPs.

In any way, CDN work requires a great amount of hardware, and its operation subsequently has an impact on and increases the pricing, additional spendings for maintenance, difficulties in troubleshooting the system, etc. At the same time, previously the best way to continuously deliver media content, traditional CDN can't solve several problems as the limited capacity of servers during the unexpectable rise of the number of viewers, additional settings requirement, or watermarks for media content in term of privacy issue.
CDN cost and quality

So, what is the price for CDN? Actually, this may be considered as a trade secret. However, real prices differ from 2$ to 9$ per Tb of traffic. It is not typical for CDN providers to show prices on public due to additional services they usually provide for clients or negotiate deals behind the scenes.

Today most CDNs going to be charging not for the volume of traffic in peering but charging for the number of viewers. No need to count billions of bytes anymore. It is quite convenient for both parties because the type of signal may remain as good as broadcasters are capable of.

how to prevent buffering
In MicroMarketMonitor's recent report, it was noted that the North American content delivery network market is expected to grow from $1.95 billion in 2013 to $7.83 billion in 2019. One significant factor driving this growth is end-user interaction with online content. This trend is widely spread these days as the audience demand for streaming video grows exponentially. However, the quality concerned to be poor. According to RapidTvNews.com, 88% of the viewers experience some disappointment from streaming video, this is due to the fact that the video starts up too long, is buffered, there is annoying advertising, the monthly data transfer costs increase and there are problems with public Wi-Fi. This is a huge call to action for media businesses to improve the situation.

Another significant trend in CDN evolution is the end-user involved in media content delivery, this is possible via peer-2-peer CDN which is the future of CDN technologies.
Decentralized CDN or Peer-2-Peer CDN

In peer-to-peer (P2P) content delivery networks, clients provide resources as well as use them. This means that unlike client-server systems, the content-centric networks can actually perform better as more users begin to access the content (especially with protocols such as BitTorrent that require users to share). This property is one of the major advantages of using P2P networks because it makes the setup and running cost very small for the original content distributor.

This technology is a foundation of Teleport Media solution. The Teleport Media platform uses P2P mesh networks and the Web Real-Time Communications (WebRTC) standard to optimize content delivery for both media business which already uses CDN servers, and CDN providers to enhance their possibilities.
