The relationship of TFRC congestion control to video rate control optimization
Rate control plays an important role in delivering video traffic over the Internet due to highly bursty nature of the video data and variability of the network bandwidth.The researchers in this area are either controlling the video rate coding or optimizing the congestion control to support the vide...

| Summary: | Rate control plays an important role in delivering video traffic over the Internet due to highly bursty nature of the video data and variability of the network bandwidth.The researchers in this area are either controlling the video rate coding or optimizing the congestion control to support the video traffic transmission.As a consequence of layering principle of the network architecture, the algorithm in each layer works independently.Thus, any optimization at video coding rate does not necessarily improve the video data transmission effectively.In this paper, we investigated the above-mentioned premise. We found that TFRC works independently from the video coding rate.Consequently, any effort to optimize the video traffic Internet transmission needs to consider employing rate control schemes both at video coding rate and congestion control algorithm. |
