Embodiment 1

[0033] The following is a specific example of the described method, such as image 3 As shown, for a cluster, there are several input sources. In this embodiment, the input source is named TOPIC[i], and i is the serial number of the input source. At the same time, the original messages on each input source are in order , each original message has its corresponding unique sequence number seqNo. After necessary filtering, the master node merges the original messages of all input sources into a sequenced input index stream T0, which contains not only the original message, but also the message source information of the original message, that is, [TOPIC, seqNo] index, which is used to uniquely locate the source of the original message.

[0034] The total sequence multicast T0 is given to the service process as input and asynchronously to the standby machine. After receiving T0, the service process outputs the input index information T0' in T0, and then outputs its response message...

Abstract

The invention relates to the technical field of information data processing, in particular to a method and system for solving a full-sequence multicast segmentation problem during one-hop cost. The method comprises that an input source sends an original message to a host, and the host sends a response message of the original message to a corresponding downstream machine in a full-sequence multicast manner; and the host generates input index information T0' according to the received original message and sends the input index information T0' to all downstream machines, wherein the input index information T0' comprises message source information of the original message and a unique serial number seqNo of the original message. Compared with the prior art, the method has the advantages that theindex information of the input original message is sent to the downstream, so the input full-sequence stream index is obtained from the downstream during fault switching, the original message is requested from the upstream according to the index and restored into the full-sequence input stream, and the segmentation problem of full-sequence multicast at the cost of one hop is solved; it can be guaranteed that the standby machine can reconstruct a message queue with complete information after taking over.

Description

technical field [0001] The invention relates to the technical field of information data processing, in particular to a method and system for solving the problem of 1-hop cost-time total-order multicast segmentation. Background technique [0002] "Total order multicast" refers to a mechanism that ensures delivery of messages to multiple independent receivers in the same order when multiple senders independently publish messages in reliable multicast. Total order multicast is the key to the core architecture of the transaction system, and the high availability of the transaction system is achieved by total order multicast. At the same time, fully ordered multicast, which is meaningful for building a high-availability core architecture, also requires protection against single-point failures. [0003] "Number of hops" refers to the number of network transmissions of messages between two devices, which has a great impact on the delay of the system. At present, mainstream exchang...
