摘要： A method for transmitting data packets and a corresponding converter are disclosed. The method includes: receiving a packet, which is sent by a source host using a Path Maximum Transmission Unit (PMTU) value supported by the source host as a Maximum Transmission Unit (MTU) value; sending an error information with a PMTU value of a translator to the source host if the PMTU value of the translator is smaller than the packet sent by the source host; receiving a packet, which is resent by the source host using a redetermined PMTU value as the MTU value, and sending the packet resent by the source host to a destination host; wherein the redetermined PMTU value is determined according to the PMTU value of the translator. The embodiments of the present invention ensure the maximum throughput of the network in the network transmission process, prevent packet loss, and improve the data transmission performance.
摘要翻译：公开了一种用于发送数据分组的方法和相应的转换器。该方法包括：接收由源主机使用由源主机支持的路径最大传输单元（PMTU）值作为最大传输单元（MTU）值发送的分组; 如果转换器的PMTU值小于由源主机发送的分组，则向源主机发送具有翻译器的PMTU值的错误信息; 接收由主机使用重定位PMTU值作为MTU值重发的分组，并将源主机重发的分组发送给目的主机; 其中根据所述翻译器的PMTU值确定所述重新确定的PMTU值。本发明的实施例确保网络传输过程中网络的最大吞吐量，防止分组丢失，提高数据传输性能。

摘要： Embodiments of the present invention disclose a method, apparatus, and system of DAD proxy. The method includes: obtaining a DAD-NS message; comparing the obtained DAD-NS message with locally stored DAD information, and adding the DAD-NS information to the locally stored DAD information when it is determined, according to a comparison result, that the IP address to be detected is not duplicate; when it cannot be determined whether the IP address to be detected is duplicate or not, initiating, according to the address information included in the locally stored DAD information after comparison, an unreachability detection to the IP address to be detected to determine whether the IP address to be detected is duplicate. The apparatus includes: an obtaining module, a storing module, and a processing module. The system includes: an apparatus of DAD proxy and an access device.
摘要翻译：本发明的实施例公开了DAD代理的方法，装置和系统。该方法包括：获取DAD-NS消息; 将所获得的DAD-NS消息与本地存储的DAD信息进行比较，并且当根据比较结果确定要检测的IP地址不重复时，将DAD-NS信息添加到本地存储的DAD信息中; 当不能确定要检测的IP地址是否重复时，根据比较后的本地存储的DAD信息中包含的地址信息，发起对要检测的IP地址的不可达性检测，以确定IP地址被检测是重复的。该装置包括：获取模块，存储模块和处理模块。该系统包括：DAD代理和接入设备的装置。
