Telecom links are widely using in various sectors to send the data from one side to another side by using the Optical Fiber Cables .

Digital Video Broadcasting Industry or Streaming Media Industry also using these links to get the data from one place to another in very small period of time.

So today in the article we will get to know that how back-hauling is done by using these type of links in Telecom Industry as well as in Digital Video Broadcasting Industry.

Before it lets have a look at what is backhaul.

(1) Streaming Media Backhauling

Streaming Media Backhauling

As shown above in the figure, there are two encoders which are having feed from two different sources. One is from Live Events and second one is from Broadcaster IRD.

Now these signals from these two different sources are going into the encoder for encoding. After the encoding it is streamed to the public network. From where it goes into the Media Gateway.

This Media Gateway gives HLS streams as output to deliver services in various platforms.

Now the link from Encoders to Media Gateway comes under the backhauling. This is optical Fiber Link.

In this case if you will use SRT protocol (Secure Reliable Transport Protocol) for communication then it will be beneficial for you in terms of network congestion over public internet.

This is all about the phenomenon of how backhual works.

Conclusion Of Backhaul

Backhaul Definition is to establish a connection between remote side and Server side for transfer of data, voice and video. Which can be Wired (OFC) as well as wireless. This is called the backhauling.
