传输装置及其传输方法
摘要：
本案提供一种用以预处理系统记忆体的资料封包成片段资料封包的传输装置。传输装置包括传输引擎以及资料记忆体。传输引擎包括标头暂存器、分段控制器以及加密单元。标头暂存器储存资料封包的IP标头、UDP标头、QUIC公开标头以及QUIC私密标头。分段控制器将资料封包的负载资料分割为片段负载资料。加密单元加密QUIC私密标头与片段负载资料成加密资料。资料记忆体自传输引擎接收IP标头、UDP标头、QUIC公开标头及加密资料，并组合成片段资料封包。
摘要（英）：

The invention provides a transmission device for preprocessing a data packet or a fragment data packet of a system memory. The transmission device includes a transmission engine and a data memory. The transmission engine includes a header register, a segment controller, and an encryption unit. The header register stores the IP header, the UDP header, the QUIC public headers, and QUIC private header of the data packet. The segment controller divides the load data of the data packet into fragment load data. The encryption unit encrypts the QUIC private header and fragment load data into encrypted data. The data memory receives the IP header, the UDP header, the QUIC public header and the encrypted data from the transmission engine, and combines the IP header, the UDP header, the QUIC public header and the encrypted data into the fragment data packet.
