在给出数据流定义的基础上,从理论上分别针对传输控制协议(TCP)和用户数据包协议(UDP)提出了基于数据流的Internet网络控制系统(INCS)延时模型.数据流的定义描述了INCS中所有数据流的输入和输出特性,网络延时模型描述了TCP和UDP协议的传输延时特性.此外,提出了基于Transit-Stub的INCS延时测量模型,并通过实验验证了基于数据流的INCS延时模型的正确性.分析了INCS中不同类型的数据流适用的传输协议,从而为设计INCS提供了理论依据.
Based on the definition of data flow, a data flow-based Internet Network Control System (INCS) delay model is theoretically proposed for Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) respectively. Describes the input and output characteristics of all data streams in INCS and the network delay model describes the transmission delay characteristics of TCP and UDP protocols.Furthermore, a Transit-Stub-based measurement model of INCS delay is proposed and verified by experiments The correctness of the INCS delay model for data streams The transport protocols applicable to different types of data streams in INCS are analyzed, which provides a theoretical basis for the design of INCS.
