摘　　要：由于VxWorks平台在电信领域的巨大市场和SCTP协议在IP网传输电信业务数据的优异性能,研究基于VxWorks平台的SCTP协议具有重要的意义。通过对SCTP协议基本概念和高级特性的简单介绍及它与传统传输协议主要区别的简单对比,凸显了SCTP协议的优越性能。提出了SCTP协议的软件设计方案。重点设计了协议的初始化机制、数据发送机制和数据接收机制,重点优化了协议的实时处理能力。通过工程实践表明,即使在不稳定网络等恶劣条件下,SCTP协议能够更高效,更可靠地完成数据的传输。证明了SCTP协议作为下一代传输协议具有广阔的前景。VxWorks platform has a huge market in the field of telecommunications and the SCTP protocol exhibits outstanding performance in IP network transmission of telecommunication traffic,so it is very important to research SCTP protocol based on VxWorks platform.This paper introduces the basic concept and advanced features of the SCTP protocol,and makes a brief contrast with the traditional transfer protocol,thus showing the superior performance of the SCTP protocol.SCTP protocol software design is also proposed with focus on the design of the protocol initialization mechanism,data transmission mechanism and the data receiving system,this optimizes real-time processing capability of the protocol especially.The engineering application shows that even in unstable networks and other adverse conditions,SCTP protocol can be more efficient and more reliable in data transmission,and SCTP protocol has broad prospects as a next-generation transport protocol.
