Problems solved by technology

However, it also leads to too many useless detection packets when there is no data transmission, which wastes bandwidth resources and leads to scalability problems
[0018] 2) NACK trigger mechanism leads to lengthy retransmission delay
After that, you need to wait for 7 more probe messages before sending and retransmitting, which will cause lengthy retransmission delay

Embodiment Construction

[0037] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0038] The embodiment of the present invention aims at the problem that the fast LCT in TIPC generates too many useless detection messages and consumes bandwidth resources when there is no message transmission, and proposes to use DST to replace the original constant-rate link continuous detection timer of TIPC ( LCT).

[0039]According to the previous analysis of the four timer functions of the LCT, it can be seen that the two ends of the communication do not always need fast timers to ensure performance. In the embodiment of the present invention, when the DST of the local end expires, if no message from the opposite end is received within the current timing interval of the DST, a detection message is sent to the opposite end, and the timing interval of the DST is extended, and DST is restarted. In this way, when th...

Abstract

The invention relates to a method for transmitting message, which comprises the following steps that: when a dynamically-regulated synchronous timer of a local end is overtime and if a message of an opposite terminal is not received in a current timing interval, a detection message is sent to the opposite end; the timing interval of the dynamically-regulated synchronous timer is prolonged; and then, the dynamically-regulated synchronous timer is restarted. The invention also relates to a system for transmitting the message. When the DST is overtime, the timing interval of the DST is prolonged; therefore, the detection message is sent in a relatively long timing interval when no data is transmitted so as to avoid generating overmany useless detection messages, so that the resource of bandwidth is saved.

Description

technical field [0001] The invention relates to inter-process communication technology, in particular to a message transmission method and system applied to inter-process communication. Background technique [0002] In a modern distributed communication system, the inter-process communication mechanism provides an information communication channel between different processes in the same host or different hosts, and plays the role of information synchronization and event notification. An efficient and reliable inter-process communication mechanism ensures the response speed of the distributed system to events and the coordination ability between different processes, and is one of the key technologies to ensure the overall performance of the system. At present, with the development of computer chip technology, the performance of a single-machine single-chip has been developed to the limit. In order to further improve computing performance, a large-scale cluster computer syste...
