An Improvement on TCP Congestion Control Protocol for Next Generation Networks

Recent years have shown an increased interest towards multimedia rich applications. Multimedia content ranges from text or simple images to audio data or video data. A Next-Generation Network (NGN) is a packet-based network that handles multiple types of traffic (such as voice, data, and multimedia). Multimedia applications include large amount of data, high throughput, and multiple flows which need diverse QoS characteristics. Nowadays, many applications use TCP as their transport protocol. As the network evolves, many improvements and modifications are proposed to make TCP meet various requirements. TCP, although powerful and effective, is not sufficient to satisfy real time applications because TCP emphasizes more on reliability than timeliness.
