Method for transmitting messages between network equipment

Abstract

The invention discloses a method for transmitting messages between network equipment, which comprises the following steps: a, establishing a retransmission array by taking a message identifier ID as an array index; b, when a request is generated, inserting the request into the retransmission array by taking the message identifier ID as the array index, and sending a message; c, sending a request message, simultaneously setting a retransmission timer for the sent message, if a response is not received when the timer is time out, taking opposite end ID + message ID as a return value, retrievinga unit that the opposite-end node ID takes the message ID as the array index, positioning to a retransmission array element for retransmitting the request message, accumulating transmission times, anddeleting the message from a retransmission list if the transmission times exceed a designed maximum retransmission time threshold; and d, when the response is received, directly positioning to the retransmission array element according to the message ID, and deleting the corresponding request message. The method can greatly improve the efficiency of retransmitting the messages of the network equipment, acquires flexible balance between system resource occupation and the timeliness of message notification restoration, and ensures the accuracy of message transmission.

Description

technical field [0001] The invention relates to a message transfer method between network devices in the field of data transmission. Background technique [0002] In the field of data transmission, more and more application systems use message notification as the interaction mode. When the message is transmitted, due to the failure of the two systems or the transmission link, the message is lost during the transmission process and cannot be delivered in a timely and reliable manner. In response to this problem, various message resending mechanisms have been formed to resend messages that have not been delivered successfully. Using the resend mechanism, in the case of unsuccessful sending for the first time, multiple sending attempts can be made, which largely solves the problem of undeliverable message sending. However, for medium and long-term communication failures, due to multiple retransmission attempts, both sending time is wasted and system resources are occupied, re...

Problems solved by technology

[0005] The disadvantage of the polling and scanning method is that if the request message retransmission linked list is too long, the workload of traversing the linked list is very large. When the retransmission timer expires and when the response is received, the entire linked list will be traversed, which will greatly consume CPU resources.

Fallback handling of first send failures can also cause accumulation of messages
