Embodiment Construction

[0017] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] In the Ethernet transmission protocol, data is encapsulated into packets for transmission. Since the network transmission protocol has strict restrictions on the length of the message, for a large file, it is usually necessary to divide it into multiple messages for transmission separately. The first transmission message of a file is called an initial message, the last transmitted message is called a completion message, and the intermediate messages are collectively called intermediate messages. In the logic design, different file messages are distinguished by link numbers, that is, the logic will assign a unique link number to each file, and all messages belonging to the file have the same link number. The sof...

Abstract

The invention relates to a multi-site protection design method, which comprises the following steps of: dividing each message of a file into an initial message, an intermediate message and a completion message; judging the received message, and executing an initial message processing flow through link number management, serial number maintenance and a field protection mechanism according to the judgement that the message is the initial message; and after the non-initial message is received, a data processing flow of the non-initial message is started through link number management, serial number maintenance and a field protection mechanism. According to the multi-site protection design method, the whole design is introduced, unsafe factors of transmission can be eliminated for multi-link concurrent network transmission, and error-free and efficient transmission of data is ensured.

Description

technical field [0001] The invention relates to network communication technology, in particular to a design method for multi-site protection. Background technique [0002] In network communication, in order to ensure the security of network data transmission, it is usually necessary to process the network data to be transmitted. Due to the limitations and requirements of the performance of the data processing module, the network data packets input to the data processing module must be continuous. Due to objective conditions such as imperfect Ethernet transmission security mechanism and limited cache resources in the logic, in the case of data transmission with large throughput and large bandwidth, it is inevitable that some packets will be lost during transmission, which will cause The data processing is disordered, leading to the paralysis of the entire system. Contents of the invention [0003] The purpose of the present invention is to provide a multi-site protection ...
