A study on bandwidth manipulation tools in Video Streaming

Nowadays, video streaming is a widely acquiring lot of popularity among television and mobile users. To maintain a high-quality video streaming, several approaches are developed using probing tools like improving bandwidth over a network. The available bandwidth of the link and the path directly impacts the performance and efficiency of throughput in streaming applications. Several tools have been devised already to estimate the available bandwidth while streaming videos. The unpredictability of the available bandwidth over a network makes the design of measurement algorithms very challenging nowadays. Measurements of available bandwidth and link bandwidth on an end-to-end process are getting more important on the Internet. In this paper, I have discussed about the concepts, difficulties and protocols of video streaming over the internet and also study about the probing models and techniques which are used to compute the available bandwidth in the network.
