摘要
为了识别出IPv4、IPv6混合网络中对性能影响较大的IPv4/IPv6过渡元素,提出了一套基于Traceroute路径的IPv6骨干网过渡元素识别策略。该识别策略结合了PMTU试探、双栈节点识别、相邻双栈提取、ping注入、跳限检验等方法,合理设计了识别流程,采用粗判以提高识别效率,并加入了验证环节保证识别的准确度。实验结果表明,该识别策略能够识别出各种过渡元素,并且具有识别速度快,识别率高的特点。
To recognize the transition components in the IPv4-IPv6 coexisting network, a transition component discovery method for IPv6 backbone network based on Traceroute path is proposed. It legitimately combines PMTU discovery, dual-stack node recognition, adjacent dual-stack nodes extraction, ping injection and hop-limit check. In special, the efficiency is improved by an initial gross judgments, and the accuracy is ensured by additional validation. Results of experiment indicate the proposed method is capable to recognize mainly used transition components with high recognition rate and high efficiency.
