摘　　要：网络IP报文的大小受链路层最大传输单元(MTU)限制,当报文长度超过MTU时,IP数据报文会被分成若干较小的部分进行分片传输,对网络通信各传输节点的承载能力以及整个传输链路的可靠性和适应性提出了严峻挑战。针对IP分片现象,介绍了超长数据包网络传输过程中会存在的问题,提出了基于网络数据包的自适应组包方法,并通过案例进行了测试分析,证明了该方法的可行性。The size of network IP message is limited by the Maximum Transmission Unit(MTU)of the link layer.When the message length exceeds MTU,the IP data message will be divided into several smaller parts for fragment transmission.This poses a severe challenge to the carrying capacity of each transmission node and the reliability and adaptability of the whole transmission link.Aiming at the IP fragmentation phenomenon,an adaptive packet method is put forward to solve the problem of extremely long data message transmission.And the feasibility of the method is tested and analyzed by practical examples.
