一种跨平台的实时TCP/IP协议栈设计
A Design of Cross-platform Real-time TCP/IP Protocol Stack
摘要
Abstract
In order to improve the real-time performance of a heterogeneous communication system,this paper proposes a cross-platform Real-time TCP/IP( RTTCP/IP) protocol stack. It introduces an OS independent layer in RTTCP/IP to shield the difference of system-level data processing to provide a good portability and extensibility. It simplifies the standard TCP/IP in RTTCP/IP so that less system resources are demanded, which makes RTTCP/IP a light-weight protocol stack. It avoids duplicating the data packets while delivering the data within the RTTCP/IP protocol stack,and it attempts to adopt a TDMA MAC in the RTTCP/IP protocol stack to avoid communication collisions. Besides, to guarantee the emergency data can be processed in the foreseeable period of time,it introduces a priority mechanism to tackle the thread,or packet,priority reversing problem. Test results show that the RTTCP/IP implementation method can reduce the system overhead and communication delay,and improve system real-time performance and stability.关键词
