A Hybrid Transport Protocol for High Speed Data Transferring in Long Fat Network

There are many emerging eScience applications. More and more scientists want to collaborate on their investigation with international partners without space limitation by using these applications. Since these applications have to analyze the massive raw data, scientists need to send and receive the data in short time. Most of applications use TCP for data transfer. But TCP was designed under low bandwidth network, therefore, general TCP, for example Reno TCP, cannot utilize the whole bandwidth of high capacity network. There are several TCP variants to solve TCP problems related to high speed networking. They can be classified into two groups: loss based TCP and delay based TCP. In this paper, I will compare two approaches of TCP variants and propose a hybrid approach for high speed networking
