Problems solved by technology

However, this method also does not define a policy for persistent storage of messages, so it cannot ensure that undelivered messages will not be lost in the event of network anomalies or failures or system crashes; in addition, this method does not involve message addressing issues, Therefore, it can only handle message delivery without an intermediary node; moreover, for some messages that need to be retransmitted due to exceptions or failures, this method does not specify how the sender should take the time interval according to the feedback information of the receiver after the message delivery fails. , How to redeliver messages and strategies

[0053] 1. Peer-to-peer two-way message delivery

[0054] The method for ensuring reliable delivery of Web service messages proposed by the invention stipulates that the delivery of Web service messages is carried out in a peer-to-peer two-way delivery mode. The so-called peer-to-peer two-way transmission means that any one of the two parties in the message transmission is not only the sender of the message, but also the receiver of the message, and the message is transmitted in both directions at the same time.

[0055] As shown in Figure 1, for the convenience of description, the role of the node that transmits the message is marked with the right subscript, the beginning of the left and right arrow keys represents the sender, and the end represents the receiver. The specific steps are as follows:

[0056] 1. Arbitrarily select two nodes X and Y to participate in message delivery;

[0057] 2. Two nodes continuously send messages X to each other 发送方 → Y, Y 发送方 →X, at this t...

Abstract

This invention relates to a method for securing reliable transmission of Web messages including a peer-to-peer double-way transmission mode, permanent storage, information confirmation and a selection re-sending system, a reliable character definition and hierarchical strategy and a support multi-message confirmation mode to secure reliable transmission of Web service messages, in which, the peer-to-peer double-way transmission mode means that the two parties transmitting messages are both the transmitter and the receiver and messages are transmitted in the peer-to-peer two parties simultaneously, the permanent strategy refers to setting a buffer region for sending information and one for receiving information for every node to store and receive information so as to transmit information after resuming system and network fault and before new fault happens, the confirmation, selection and re-sending system, the reliability character definition and the support multi-message confirmation mode are used to secure reliable transmission of messages by defining reliable character, confirmation of the ID and re-sending information.

Description

technical field [0001] The invention relates to a method for ensuring reliable delivery of Web service messages. Background technique [0002] Web service is a technology that enables applications to communicate with each other in a platform-independent and programming-language-independent manner. Since the means of communication used by Web services is message delivery, it becomes a crucial issue whether the message can be reliably transmitted from the sender to the receiver. The basic goal of ensuring reliable delivery of messages is to ensure that Web service messages are reliably transmitted from the sender to the receiver even when the application program is abnormal, the system crashes, or the network fails. Specifically reflected in: 1. When the system does not crash, but network failure or abnormal interruption occurs, it can still ensure that all messages generated by the sender application are delivered to the receiver's application; or, 2. When the system occurs ...
