High performance data transfer services is needed in long distance high-speed networks. In this paper Adaptive Layered Transmission Control Protocol (ALTCP) is proposed, which is used for making more scalability in high-speed networks. ALTCP is a simple adaptive layering technique for making the Additive Increase Multiplicative Decrease (AIMD) algorithms used by TCP more efficient in probing for the available link bandwidth. ALTCP uses a three-dimensional congestion control framework. First the macroscopic control is employed to layer quickly and made efficient by using available link bandwidth, second microscopic control is used for extends the existing AIMD algorithm of TCP to determine the per acknowledgement behavior. Third the intermediate control is employed for decoupling the aggregate throughout from the number of opened TCP flows in parallel. In this research paper ALTCP protocol is designed and analyzed based on ns-2 simulations. The results show that ALTCP has faster magnitude than TCP in utilizing high bandwidth links. ALTCP has better TCP friendliness and Round Trip Time (RTT) fairness compared with high-speed protocols namely High-speed TCP and Scalable TCP.

Abstract


High performance data transfer services is needed in long distance high-speed networks. In this paper Adaptive Layered Transmission Control Protocol (ALTCP) is proposed, which is used for making more scalability in high-speed networks. ALTCP is a simple adaptive layering technique for making the Additive Increase Multiplicative Decrease (AIMD) algorithms used by TCP more efficient in probing for the available link bandwidth. ALTCP uses a three-dimensional congestion control framework. First the macroscopic control is employed to layer quickly and made efficient by using available link bandwidth, second microscopic control is used for extends the existing AIMD algorithm of TCP to determine the per acknowledgement behavior. Third the intermediate control is employed for decoupling the aggregate throughout from the number of opened TCP flows in parallel. In this research paper ALTCP protocol is designed and analyzed based on ns-2 simulations. The results show that ALTCP has faster magnitude than TCP in utilizing high bandwidth links. ALTCP has better TCP friendliness and Round Trip Time (RTT) fairness compared with high-speed protocols namely High-speed TCP and Scalable TCP.
