摘　　要：流控制传输协议(SCTP)作为一种新兴的网络传输技术协议,由于其具有的多宿主(Multi-homing)和多流(Multi-streaming)等功能,使其必将成为下一代网络中的传输层协议中的主导,在未来互联网和移动网络中发挥重要作用,然而目前网际协议(IP)网络中大多数网络地址转换(NAT)设备对SCTP报文转发缺乏兼容支持。分析并解决了SCTP在当前IPV4网络实施中所遇到的NAT阻断问题,利用在收发端协议栈上进行功能扩展,提出了一种新的SCTP报文的NAT映射传输方法,在不修改当前网络NAT设备的前提下完成NAT映射,并通过测试验证了解决方案的可行性和有效性。Stream control transmission protocol （ SCTP protocol ） as a new network transnfission technology, because of its nmltihost（ Muki-homing ）and flow（ Multi-streaming ）and other functions, so that it will become the dominant transport layerprotocol of the next generation of network, play an important role in the future of the Internet and mobile networks, however at present, most of the lnternet Protocol （IP） network address translation network （NAT） equipment for SCTPmessage forwarding the lack of compatibility support. Analyze and solve the SCTP encountered in the current IPV4 network implementation of the NAT blocking problem, using the extensions in the transmitter and receiver protocol stack, the NAT mapping transmission method for a new SCTP message, NAT completed mapping without modification of the current NAT network equipment, and through the test solution the feasibility and validity of.
