摘要： A distributed system for ensuring that message data is not damaged during send and receive processing of said message includes a memory (2002) for storing an application program (2006), a CPU (2001) for executing it, and a network controller (2003) for sending a message onto a network (2005), send data memory means (2025) for storing send data generated by said application program (2006); send protocol processing means for receiving send data stored in said send data memory means (2025) and executing a predetermined send protocol processing to compose a message be transferred to said network controller (2003), using said send data. The system comprises a first mode (502 - 508) having many processing sequences for enhancing reliability of communication by checking a message-to-be-sent, a second mode (501) having less processing sequences in which a message-to-be-sent is sent as it is, and means for selecting one of the modes.
摘要翻译：用于确保消息数据在所述消息的发送和接收处理期间不被损坏的分布式系统包括用于存储应用程序（2006）的存储器（2002），用于执行它的CPU（2001）和网络控制器（2003）用于向网络（2005）发送消息，发送用于存储由所述应用程序（2006）生成的发送数据的数据存储装置（2025）。发送协议处理装置，用于接收存储在所述发送数据存储装置（2025）中的发送数据，并使用所述发送数据执行预定的发送协议处理以组合要传送到所述网络控制器（2003）的消息。该系统包括具有许多处理顺序的第一模式（502-508），用于通过检查要发送的消息来增强通信的可靠性，具有较少处理顺序的第二模式（501），其中消息要被发送，发送原样，以及用于选择其中一种模式的装置。

摘要： The highly reliable distributed system is composed of a communication protocol processing unit which comprises a mailbox (2023) for storing a communication message, and executes communication protocol processing between data of an application program (2006) and a network controller (2003) using the network controller (2003) performing network communication of the message in the mailbox (2023); an error detection coding unit (2075); an error detection decoding unit (2076) which reconverts data converted from communication data by the error detection coding unit (2075) to the original data, and detects that the content of the data is damaged if it is damaged; and a data comparing unit for checking whether or not two kinds of data agree with each other.
摘要翻译：高度可靠的分布式系统由通信协议处理单元组成，该通信协议处理单元包括用于存储通信消息的邮箱（2023），并且使用网络执行应用程序（2006）和网络控制器（2003）的数据之间的通信协议处理控制器（2003）执行邮箱（2023）中的消息的网络通信; 错误检测编码单元（2075）; 错误检测解码单元，其将由所述错误检测编码单元（2075）从通信数据转换的数据重新转换为所述原始数据，并且如果所述数据损坏则检测到所述数据的内容被损坏; 以及用于检查两种数据是否彼此一致的数据比较单元。
