Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for transmitting a message.

Background

In the prior art, message middleware is a tool for asynchronous communication between systems, focuses on sending and receiving data, and integrates a distributed system by using an efficient and reliable asynchronous message transfer mechanism. The method is mainly used for solving the problems of application decoupling, asynchronous messages, flow peak clipping and the like.

It can be understood that, the message middleware performs message transmission through the message channel, and message identifiers in the intermediate state are all stored in the channel sending queue, but in practical applications, the receiving and sending end rates are often not matched due to network bandwidth or machine performance difference, and specifically: when the sending end speed is too high, messages can be accumulated in a sending queue, and congestion is caused; when the sending end is too slow, resources are wasted and rapid transmission cannot be achieved, so that congestion control needs to be performed on a channel of the sending end to match the processing rate of the receiving end and the sending end. The existing method for controlling queue congestion detection includes determining repeated ACK, detecting the number and change rate of messages in the queue, detecting the memory utilization rate and the like, considering that a channel is congested when an abnormal condition occurs, and performing corresponding abnormal processing.

In the above conventional message transmission method, a processing method for detecting the number of messages in the message queue and the change rate of the number of messages is generally used to compare with a preset message number threshold and a preset message rate threshold, and if the number of messages is higher or lower than the threshold, it is considered to be abnormal, and corresponding abnormal handling is performed. The message quantity and the change rate are relatively dependent on the actual message quantity in the current queue, the message quantity and the change rate have reference significance only when the message is stable to reach a certain magnitude, and the preset threshold value is not easy to artificially confirm in advance and cannot adapt to various complex network scenes.

The method of handling message channel congestion by detecting the memory usage of the consumer itself also has drawbacks: when the memory utilization rate reaches the set feedback triggering condition, the producer is informed to adjust the message sending window so as to achieve the effect of flow control. The influence factors of the memory utilization rate of the consumer are more, the situation that the receiving capacity is insufficient cannot be clearly reflected, the consumer actively informs the producer, the producer does not actively adjust, and certain time delay may exist to cause congestion.

In summary, there is a need in the art for a method that can adjust the sending interval and the sending queue depth of the message channel in real time to achieve better solution for message transmission.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

An embodiment of the present invention provides a specific implementation of a message transmission method, and referring to fig. 1, the method specifically includes the following steps:

step 100: the average message transmission delay over the last cycle is calculated.

Specifically, the average message transmission delay in the previous period is periodically and dynamically calculated, and it should be noted that "periodically", i.e. one calculation period and "in-period" in step 100, refer to a time interval. The message transmission process can be simplified into the processes of putting the message into a sending queue → transmitting the message in a network → a receiving end processing a sending receipt → transmitting the receipt in the network → a sending end confirming the receipt and deleting the local cache message, and the like, wherein the time difference between the starting time of putting the message into the sending queue and the ending time of confirming the receipt is the integral transmission delay of the message, and the average transmission delay of the messages within one period is obtained by averaging the transmission delays of the messages.

Step 200: and calculating the ideal maximum depth of the message queue in the current period according to the plurality of average message transmission delays.

It can be understood that the depth of the message sending queue determines the sending concurrency number, when the sending concurrency number is too high, accumulation can be caused to influence the processing speed of a sending end, and when the sending concurrency number is too low, idle can be caused; therefore, the ideal maximum depth of the sending queue is positively correlated with the network transmission delay (the whole transmission delay minus the processing time of the receiving end) and inversely correlated with the processing time after the receiving end receives the message, the processing time of the receiving end is carried to the message sending end through the receipt for reference, and then the maximum depth of the ideal queue can be obtained according to the relation and the lower limit of the constant depth (the lower limit of the constant depth is generally set according to the empirical value, the factors of the bandwidth of the actual using environment, the machine memory and the like can be comprehensively considered, when the bandwidth is higher and the machine memory is larger, the upper limit and the lower limit of the preset sending interval can be both adjusted lower, and the upper limit and the lower limit of the maximum depth of the sending queue can be both adjusted higher).

Step 300: and controlling a message channel according to the average message transmission delay and the ideal maximum depth.

Specifically, the average message transmission delay in the latest period is calculated by sampling, and with this as a reference, the message channel is controlled by adjusting the transmission interval and the maximum depth of the transmission queue according to the average message transmission delay.

As can be seen from the above description, in the message transmission method provided in the embodiment of the present invention, first, the average message transmission delay in the last period is calculated; then, calculating the ideal maximum depth of the message queue in the current period according to a plurality of average message transmission delays; and finally, controlling the message channel according to the average message transmission delay and the ideal maximum depth. By periodically sampling the message transmission delay and adjusting the sending interval and the sending queue depth according to the message transmission delay, the congestion of a message channel can be well controlled only by controlling a sending end (without controlling a message receiving end), the value is kept at a stable value under the current machine and bandwidth load, the computing resources are utilized to the maximum extent, and the resource utilization is low by the periodic sampling mode.

In one embodiment, referring to fig. 2, step 100 comprises:

step 101: calculating the message transmission time delay of the plurality of messages in the last period according to the processing performance parameters of the receiving and transmitting terminal machine, the network broadband and the receiving and transmitting terminal queue depth;

it can be understood that the single message transmission delay means that the whole process is influenced by the processing performance of the machine at the transceiving end, the network bandwidth, the queue depth of the transceiving end, and the like until the local end confirms that the opposite end receives the message from the local end.

Specifically, the transmission delay of each message is the time difference between the local terminal sending time and the local terminal receiving time for confirming the opposite terminal receiving time. Affected by factors such as processing performance, bandwidth, etc.

Step 102: and calculating the average message transmission delay in the last period according to the message transmission delays of the plurality of messages.

Preferably, the average message transmission delay is calculated by using the message transmission delays in a plurality of stable periods, where a stable period refers to a period (less than a preset threshold time) in which the variation amplitude of the average message transmission delay is small.

In one embodiment, referring to fig. 3, step 200 further comprises:

step 201: calculating the message concurrency number and the network transmission delay according to the average message transmission delay;

step 202: and calculating the ideal maximum depth according to the message concurrency number and the network transmission delay.

In one embodiment, referring to fig. 4, step 300 further comprises:

step 301: comparing the average message transmission delay in the multiple periods with the sending interval time in the current period;

step 302: when the average message transmission delay in the multiple periods is greater than the sending interval time in the current period and the sending interval time in the current period reaches the preset message sending interval time upper limit, comparing the message queue depth in the current period with the preset message queue maximum depth;

step 303: and when the depth of the message queue in the current period is not greater than the preset maximum depth of the message queue, reducing the preset maximum depth of the message queue to the depth value of the message queue in the current period.

In one embodiment, referring to fig. 5, step 301 further comprises:

step 3011: and when the average message transmission delay in the multiple periods is greater than the sending interval time in the current period and the sending interval time in the current period does not reach the preset message sending interval time upper limit, increasing the sending interval time in the current period to the preset message sending interval time upper limit.

It can be seen that steps 302 and 304 are two counter examples of the case that the sending interval time in the current period reaches and does not reach the preset upper limit of the message sending interval time on the premise that "when the average message transmission delay in the multiple periods is greater than the sending interval time in the current period".

In one embodiment, referring to fig. 6, step 301 further comprises:

step 3012: when the average message transmission delay in the multiple periods is not larger than the sending interval time in the current period, comparing the average message transmission delay in the current period with the average message transmission delay in the previous period;

step 3013: the average message transmission delay in the current period is greater than the average message transmission delay in the last period, and the message sending interval time in the current period is increased to a preset message sending interval time upper limit;

step 3014: and if the average message transmission delay in the current period is not greater than the average message transmission delay in the last period, reducing the message sending interval time in the current period to a preset message sending interval time lower limit.

In one embodiment, based on the result of any of steps 3011-3014, there are:

when the ideal maximum depth is larger than the preset maximum depth of the message queue in the current period, increasing the depth of the message queue in the current period to the preset maximum depth of the message queue;

and when the ideal maximum depth is not greater than the preset maximum depth of the message queue in the current period, reducing the preset maximum depth of the message queue to the depth value of the message queue in the current period.

To further illustrate the present solution, the present application provides a specific application example of the message transmission method, see fig. 7 and fig. 8, and the specific application example specifically includes the following contents.

S1: periodically sampling and calculating the average message transmission delay of a channel in the latest fixed time period, simultaneously storing the average message transmission delay of the last period, and calculating the maximum depth (ideal maximum depth) of an ideal sending queue matched with the average message transmission delay in n stable periods (the change amplitude of the average message transmission delay is small);

s2: presetting upper and lower limit values of a message sending interval and upper and lower limit values of the maximum depth of a sending queue, and defaulting the current message sending interval and the maximum depth of the current sending queue to be the respective upper limit values, and comparing the average message transmission delay with the current message sending interval at the end of each period; specifically, referring to fig. 9, step S2 includes:

a) if the average message transmission delay is greater than the current message sending interval and the current message sending interval reaches the upper limit value of the message sending interval, the depth of the current sending queue and the maximum depth of the current sending queue need to be judged; referring to fig. 10, step a) includes:

i. if the depth of the current sending queue is less than or equal to the maximum depth of the sending queue, the maximum depth of the current sending queue is reduced proportionally to the lower limit value of the maximum depth of the sending queue or the depth of the current sending queue;

a case where the current transmit queue depth is not greater than the transmit queue maximum depth;

b) if the average message transmission delay is larger than the current message sending interval and the current message sending interval does not reach the upper limit value of the message sending interval, the current message sending interval is increased proportionally;

c) if the average message transmission delay is less than or equal to the current message sending interval, judging the current average message transmission delay and the average message transmission delay of the previous period; referring to fig. 11, step c) further comprises:

c 1: if the current average transmission delay is larger than the average message transmission delay of the previous period, the current message sending interval is increased in proportion until the current average transmission delay reaches an upper limit value;

c 2: if the current average transmission delay is less than or equal to the average message transmission delay of the previous period, reducing the current message sending interval in proportion until the current message sending interval reaches a lower limit value, and simultaneously entering the step S3 to adjust the maximum depth of a sending queue;

d) if the sampling messages in the previous period are not completely transmitted, increasing the current message sending interval in proportion;

e) if no message is transmitted in the previous period, the message sending interval is not adjusted;

s3: after each n stable periods are finished, comparing the maximum depth of the sending queue obtained by calculation with the maximum depth of the current sending queue;

referring to fig. 12, further, step S3 includes the following steps:

f) if the calculated maximum depth of the sending queue is larger than the maximum depth of the current sending queue, the maximum depth of the current sending queue is increased in proportion until the maximum depth reaches an upper limit value;

g) and if the calculated maximum depth of the sending queue is less than or equal to the maximum depth of the current sending queue, reducing the maximum depth of the current sending queue according to a proportion until the maximum depth reaches a lower limit value or the actual current depth of the current sending queue.

In the specific application example of the invention, a special time delay structure data structure is arranged for the channel in the message middleware, a certain number of message state time is stored, and after the message is finally sent, the transmission time delay of the message is calculated. And simultaneously setting data structures such as the maximum depth and the sending interval of the sending queue.
