| 摘 要： | 在易错网络中传输IP(因特网协议)数据包时,除了网络拥塞之外,信道误码也容易导致数据包丢失。丢包对信源恢复会造成较大影响。为了降低误码导致的丢包率,该文研究了IPv4协议解码的可靠性问题,分析了IPv4(因特网协议版本4)协议各字段之间的相关性,建立了IPv4协议容错解码的理论模型,利用最大后验概率推导出容错解码的准则。在该基础上提出一种以分段方式估计协议字段的算法,实验结果表明该算法大大增强了IPv4协议解码的纠错能力。

| Abstract: | When transmitting Internet protocol (IP) packets over error-prone networks,bit error can cause packet loss besides network congestion.Packet loss makes a strong impact on source recovery.For the sake of decreasing packet loss ratio,we consider the problem of error resilient decoding for internet protocol version 4 (IPv4).The correlation between fields in IP packet header is analyzed,a mathematical model for error resilient IPv4 decoding,and the error resilient decoding criterion using maximum a posterior (M... |
