摘　　要：随着计算机网络的持续快速发展,对网络应用的需求不断涌现,网络拥塞问题也变得日益严重,其一直是网络研究的关键难题和热点问题。TCP协议是传统互联网广泛应用的传输控制协议,但单一路径的TCP传输协议已不能满足网络发展的需要,日益显现出其固有的局限性;另一方面,随着接入技术与接入方式的多样化发展,使得多路径并行传输成为可能。面向连接的新型互联网传输控制协议是一种多路径的传输协议,其发展受限于单路径传输的传统互联网拥塞控制算法。为此,针对新型互联网多路径传输协议,在总结回顾现有互联网拥塞控制机制的基础上,提出了多路径拥塞控制机制的设计原则以及适用于多路径传输协议的公平性准则。该设计原则和公平性评价准则在对比分析研究各种多路径拥塞控制算法的优缺点的基础上,引入了现有的多路径传输协议来控制网络拥塞,并揭示了网络多路径传输的发展方向。With the constant and rapid development of computer network, the demand for network applications is emerging, and the net- work congestion is becoming more and more serious, which has been the key problem and hotspot of network research. TCP, as a trans- mission control protocol,is widely used in the traditional Internet, but a single path of the TCP is unable to meet the needs of network de- velopment, increasingly showing its inherent limitations. In addition, with the diverse development of access technology and access mode, it makes multi-path parallel transmission possible. The new connection-oriented Interact transmission control protocol is a multi-path transmission protocol, which is limited to the traditional Interact congestion control algorithm with single path. For this, a new multi-path congestion control mechanism is proposed based on the review of the existing Interact congestion control mechanism, and its design prin- ciples and fairness criterion are proposed which introduce the existing multi-path transmission protocol into the control network conges- tion and reveal the development direction of the network muinpath transmission on the basis of the comparative analysis of the advantages and disadvantages of various multi-path congestion control algorithms.
