摘要/Abstract

摘要： 为实现高效可靠的网络传输协议，依据RUDP草案并引入TCP可靠机制，设计一种基于消息包、面向连接的高速可靠网络传输协议ORUDP。通过创建确认机制、重传机制、流量控制机制和双队列加速机制等实现基本协议，选择现场可编程逻辑门阵列进行ORUDP协议栈的逻辑设计和实现，在Modlesim仿真工具上完成所有设计模块的功能仿真。通过搭建测试环境对ORUDP网络协议栈进行测试，结果表明，ORUDP不仅能够可靠传输数据包，解决数据包丢失、乱序、重复到达等问题，且在包文较短、资源占用较少的情况下仍然具有较快的传输速度。

Abstract: In order to realize efficient and reliable network transmission protocol,according to RUDP draft,this paper introduces the reliable TCP mechanism to design a high speed and reliable network transmission protocol ORUDP based on message packet for connection.The basic protocol is implemented by establishing the confirmation mechanism,retransmission mechanism,flow control mechanism and double queue acceleration mechanism.Then Field Programmable Gate Array(FPGA) is selected for the logical design and implementation of the ORUDP protocol stack,and the functional simulation of all design modules is completed by using the simulation tool,Modlesim.A test environment is built to test the ORUDP network protocol stack,and the result shows that ORUDP can reliably transmit data packets,solving loss of data packets,out-of-order data packets,and repeated arrival of data packets.It keeps a high transmission speed while fewer resources are consumed and the content of packets is short.

Key words: TCP/IP protocol, transport layer protocol, retransmission mechanish, RUDP protocol, Field Programmable Gate Array(FPGA)
