Detailed Description

The inventors noted during the course of the invention that:

In view of this, the present application provides a method for processing burst messages, which includes first periodically monitoring a message burst event in real time; and if the message emergency is monitored, storing the emergency message without forwarding, and finally, distributing the stored message to different transmission lines for forwarding after the message emergency is finished. After the message emergency is monitored, the method realizes load sharing by adopting a multi-line forwarding mode for the stored emergency message, thereby solving the abnormal condition that part of the stored emergency message is discarded due to the message emergency in the related technology. In addition, during the message receiving period of the non-message emergency, the received message is forwarded according to the forwarding rule of the normal message, wherein the forwarding rule of the normal message is, for example, normal forwarding according to a determined fixed line.

Referring to fig. 1, a flow chart of a method for processing a burst packet according to an embodiment of the present application includes:

step 101: periodically monitoring a message emergency;

if a message emergency is to be monitored, a predetermined burst start feature and a predetermined burst end feature are required. When the method is implemented, firstly, the message characteristics of each monitoring period are compared with the predetermined burst starting characteristics; and if the message characteristic of the first monitoring period is matched with the predetermined burst starting characteristic from the first monitoring period, namely, the condition of the burst starting characteristic is met, determining the starting moment of the first monitoring period as the starting moment of the message emergency. After determining the starting time of the emergency, comparing the message characteristics of each monitoring period with the predetermined burst ending characteristics; and if the message characteristics of the second monitoring period are matched with the predetermined burst ending characteristics from the second monitoring period, namely, the conditions of the burst ending characteristics are met, determining that the ending time of the second monitoring period is the ending time of the message emergency. And determining that the occurrence of the message emergency is detected through the acquired starting time and ending time of the message emergency.

In one embodiment, if the predetermined burst message characteristic is a message quantity average; whether the message emergency occurs or not is monitored, and whether the message emergency occurs or not can be judged by firstly determining a preset monitoring period and comparing the number of the messages received in the last monitoring period with the average value of the message quantity. If the number of the messages received in the last monitoring period is larger than the message quantity average value, determining that the message characteristics of the monitoring period are matched with the predetermined burst starting characteristics; and judging the starting time of the monitoring period as the starting time of the message emergency. In the embodiment of the present invention, the foregoing message amount refers to the number of messages.

The message quantity average value can be a preset message quantity value or a historical statistic value obtained by real-time calculation; in one embodiment, the preset message amount may be obtained empirically by a person skilled in the art, or may be obtained in other ways that a person skilled in the art can think, and is not limited herein; in another embodiment, the historical statistic value obtained by real-time calculation may be obtained by using an average value of the number of messages received in correspondence to each monitoring period in the non-message burst period in a preset period of the historical statistic, or may be obtained by using the total number N of messages received in the non-message burst period in a period from the start time to the current time of the initiation of the message flow, the duration Δt of the non-message burst period, and the monitoring period to obtain the average value F (t), which is specifically determined according to the following formula:

In the above method, for example, the number of messages received in the last monitoring period is compared with 2 times of the average value of the number of messages. For example, from t _s Starting to enter a new monitoring period at any time until the monitoring period is finished, and judging that a message emergency occurs, namely that the message flow is bursty, because the number of messages received in the monitoring period is larger than 2 times of the average value of the number of messages, obtaining t _s The moment is the starting moment of the message emergency; similarly, a new monitoring period is started from a certain time until the end time t of the monitoring period _e When the number of messages received in the monitoring period starts to be less than or equal to 2 times of the average value of the number of messages, the monitoring period is determined to be matched with the predetermined burst ending characteristic, and then t can be determined _e And ending the message emergency at the moment, namely recovering the message flow to be normal.

In another embodiment, if the predetermined burst packet characteristic is a predetermined burst packet characteristic slope threshold, whether a packet emergency occurs is monitored, optionally, a predetermined monitoring period is first determined, and then a slope value of the packet amount received in the current monitoring period is calculated according to the implementation of "(the number of packets received in the current monitoring period-the number of packets received in the last monitoring period)/the monitoring period", and is compared with the burst packet characteristic slope threshold. When the calculated slope value of the number of messages is larger than the burst message characteristic slope threshold, determining that the message characteristic of the monitoring period is matched with the predetermined burst starting characteristic; judging the starting time of the monitoring period as the starting time of the message emergency, and judging that the message flow has an emergency; and when the calculated slope value of the number of messages becomes smaller than 0 and the absolute value < = burst message characteristic slope threshold value, judging that the message flow is normal. Wherein the slope threshold may be a value greater than zero as determined by one skilled in the art from empirical values.

In addition, the judgment of the message emergency can be realized by any other existing burst detection mechanism, which is not particularly limited in this embodiment.

In practical application, it is considered that different types of services have different transmission characteristics, and network environments are complex and changeable, and the situation that a message stream instantaneously bursts and is insufficient to cause transmission congestion to cause message loss occurs. For this purpose, as a preferred embodiment, the method provided in this embodiment may further include: if the condition that the duration time of the message emergency event from the starting time to the ending time is longer than the preset duration time threshold value is met, executing the step 103 of forwarding the message emergency event by being distributed to different transmission lines; that is, if it is determined that the duration of the message emergency is less than or equal to the preset duration threshold, the process is ended, and the processing of step 103 is not executed; and normally forwards the message according to a fixed line determined in the case of no emergency. The preset duration threshold can be determined by a person skilled in the art according to the monitoring period, and is greater than the monitoring period of the periodic monitoring message emergency event, and typically takes a value 10 times the monitoring period. In addition, the specific fixed line determination method is the prior art, and is not described herein.

Step 102: if the starting time of the message emergency is monitored, storing the message received after the starting time until the ending time of the message emergency is monitored;

in one possible embodiment, the time from the monitoring of the start of the message incident (denoted as t _s Time), counting the number of newly received messages at a fixed time, and associating the counted messages and the number of messages with the corresponding counting time until the ending time of the message emergency is monitored, namely, when the message flow is recovered from burst to normal (recorded as t) _e Time) ends.

Dividing the interval into K (K > 0) preset statistical periods during the occurrence of the message emergency, counting the number of messages corresponding to the preset statistical time according to a plurality of preset statistical time when each statistical period is ended, wherein the preset statistical time is typically an integral multiple of the clock period of a processor and is smaller than the period of the periodical monitoring message Wen Tu; the message corresponding to the preset statistical moment is a message received between the preset statistical moment and the adjacent last preset statistical moment; and associating and storing each preset statistical moment with the corresponding message and the message quantity thereof. In particular, the message corresponding to the first preset statistical moment is a message received between the preset statistical moment and the starting moment of the message burst.

Optionally, referring to fig. 2, a schematic diagram of a manner of storing burst messages provided in this embodiment of the present application is shown, where a clock period T of a device (i.e. a minimum time unit in which a CPU works) is taken as a preset statistics time, and total number of messages received in a clock period T nearest to each preset statistics time is counted according to a plurality of preset statistics times, and the total number of messages newly received is taken as the number of messages newly received in the current statistics. For example: t is t ₁ ＝t _s The number of messages counted at the moment +T is as follows: t is t _s To t ₁ The number of messages newly received in a time period f (t ₁ )；t ₂ ＝t ₁ +T＝t _s The number of messages counted at the moment +2T is as follows: t is t ₁ To t ₂ The number of messages newly received f (T ₂ )；t ₃ ＝t ₂ +T＝t _s The number of messages counted at the moment of +3T is T ₂ To t ₃ The number of messages newly received f (T ₃ ) The … … diagram is merely an example, and the number of clock cycles T is determined by the relationship between the duration of the message incident and T. Of course, the statistical time unit may be an integer multiple of the clock period T greater than 1, but is generally less than or equal to the monitoring period for determining whether the burst occurs in the packet stream.

It should be noted that, during the occurrence of the packet emergency, the packet received during the period is not forwarded, but is forwarded according to a specific splitting method after the emergency is ended, and the specific splitting forwarding method refers to step 103.

Step 103: and distributing the stored messages during the occurrence of the message emergency to different transmission lines for forwarding.

In one ofIn an embodiment, according to the message quantity associated with each preset statistical time (f (t) in step 102 _i ) Shunting and forwarding the message received during the occurrence of the message emergency, comprising: first determine each f (t _i ) Slope f' (t) _i ) The method comprises the steps of carrying out a first treatment on the surface of the Then according to f' (t _i ) And shunting and forwarding the message received during the occurrence of the message emergency. Wherein f' (t _i ) The message quantity f (t _i ) Of the slope of (a), which is physically significant in terms of the amount of the message f (t _i ) For time axis t _i Is positively correlated with the amount of increase in the amount of messages received at adjacent times. In practice, the method can be based on f' (t) _i ) And shunting each message received during the occurrence of the message emergency to different lines, and transmitting the message by adopting a plurality of lines so that the message can reach the destination end more quickly and accurately. Wherein each f (t _i ) Slope f' (t) _i ) Alternatively t _i Slope value at time; or, alternatively, f (t _i-1 ) And f (t) _i ) Slope values of the lines of (c) are provided.

In the above method, according to f' (t _i ) Determining the forwarding period of the burst message according to the relation between the burst message and a preset forwarding slope threshold value; dividing the stored burst message into a plurality of message blocks according to the forwarding period; and finally, sequentially forwarding each message block to a plurality of transmission lines for alternate forwarding, wherein each message block is forwarded by one of the transmission lines. For example, for f' (t _i ) Burst messages with absolute values smaller than a preset first forwarding slope threshold value show that the number of the partial messages changes slowly, the stored burst messages can be divided into a plurality of message blocks according to the sequence of storage time, the forwarding period is corresponding to the first forwarding time (P1) and other time periods, and finally each message block is sequentially forwarded alternately by a plurality of different transmission lines; for f' (t) _i ) Burst messages with absolute values greater than a preset first forwarding slope threshold and slopes not greater than a second forwarding slope threshold can be divided into a plurality of message blocks according to time sequence and a second forwarding duration (P2) which is smaller than the first forwarding duration (P1) and the like; whereas for f' (t) _i ) Absolute value greater than presetAnd when the second forwarding slope threshold value is positive, the number of the messages increases faster, and the plurality of message blocks can be divided according to the third forwarding time length (P3) which is smaller than the second forwarding time length (P2) and the like. For a clearer understanding of the present embodiment, different f' (t) _i ) The corresponding forwarding duration is shown in table 1:

TABLE 1

Wherein the first forwarding slope threshold<A second forwarding slope threshold, a first forwarding duration (P1) >Second forwarding duration (P1)>A third forwarding duration (P1). As can be seen from table 1, when f' (t _i ) The larger the message quantity is, the faster the burst message quantity is increased, and the message blocks with forwarding are required to be divided into a plurality of message blocks with forwarding according to the duration of smaller forwarding period and the like when the split forwarding is carried out.

In another preferred embodiment, in order to ensure that the burst message can be distributed on two lines, so as to achieve the purpose of load sharing, the following manner is preferably adopted in this embodiment to implement message forwarding. Referring to fig. 3, a flow chart of a burst packet transmission line forwarding manner provided in an embodiment of the present application includes:

step 103a: and fitting by using the discrete points corresponding to each preset statistical moment and the associated message quantity to obtain a function.

The variable of the function is time, and the function value is the number of messages associated with the time. When in implementation, each preset statistical time t acquired in the occurrence period of the message emergency event is counted _i And its associated message quantity f (t) _i ) As discrete point coordinate values (t _i ，f(t _i ) Fitting to obtain a function f (t). The specific fitting process is the prior art, and is not described herein again; preferably, the fitting algorithm uses a least squares method, higher order function f (t) =k0+at+bt ² +…+nt ^m 。

Step 103b: judging whether the fitted function f (t) is conductive to time during the occurrence of the message emergency; if yes, proceed to steps 103c-130e; if not, go to step 103f;

step 103c: calculating the residence point of f (t) in the occurrence period of the message emergency;

i.e. the point where the derivative of f (t) is equal to 0, and thus the corresponding at least one dwell point instant t _z ；

Step 103d: dividing the function into a plurality of monotonic intervals according to the residence point of the function;

with the burst start time t of the message flow _s Each residence time t _z End time t of message stream burst _e Dividing the time partition during the occurrence of the message emergency as a dividing point, wherein each interval obtained by dividing is a monotonically increasing or monotonically decreasing interval;

step 103e: dividing the burst message in the monotonic interval into two sub-intervals for transmission line division forwarding;

in implementation, referring to fig. 4, a flow chart of another burst packet transmission line forwarding manner provided in an embodiment of the present application includes:

step 401: determining the average value of burst message quantity in each monotonic interval as a first average value;

in practice, for each divided monotonic interval obtained, a first mean value within each monotonic interval is optionally calculated according to the following formula:

Referring to fig. 5, a schematic diagram of dividing a monotonic interval is provided in an embodiment of the present application; wherein t' _s The start time indicated as monotonic interval 1 (fig. 5 is also the start time t of a message incident _s )，t’ _e End time, denoted as monotonic interval 1, f (t _ξ ) The average value of the burst message quantity of f (t) in the monotonic interval 1;

step 402: searching designated discrete points of each monotonic interval;

in implementation, each preset system for acquiring records in the monotone sectionThe sum f (t) in the number of messages counted at the counting time _ξ ) The nearest number of messages f (t' _ξ ) By the number of messages f (t' _ξ ) Corresponding preset statistical time t' _ξi Discrete points are specified within the monotonic interval. For example, f (t 'in FIG. 5' _ξ1 ) Corresponding t' _ξ1 Discrete point 1 is designated for monotonic interval 1.

Step 403: dividing the time of the monotonic interval into two subintervals by taking the preset statistical moment corresponding to the appointed discrete point as a critical point; and distributing the messages between the two sub-intervals to different transmission lines for forwarding.

In implementation, the number of messages counted according to each preset counting time recorded in each monotone section and f (t ')' _ξ ) The size relation of the packet stream received in the dividing interval is divided; in specific implementation, the following splitting mode can be adopted: the divided section is further divided into two sub-sections with reference to a specified discrete point: for the corresponding message number exceeding f (t' _ξ ) The message received in the subinterval of (1) is forwarded through the wired line and the wireless line together; for the corresponding message number not exceeding f (t' _ξ ) The message received in the subinterval of (2) is forwarded via the wire line. The messages in the two intervals may be divided into different transmission lines, and the specific transmission line to be used is not limited.

Step 103f: and if the message is not led, shunting and forwarding the received message flow.

If the function is not conductive during the occurrence period of the message emergency, in one embodiment, the burst message is alternately forwarded by the sub-transmission lines according to the preset statistical moments, wherein the message corresponding to one preset statistical moment is forwarded by one transmission line. For example, referring to fig. 6, a schematic diagram of burst packet forwarding in the embodiment of the present application is provided, and the statistical time t is preset currently _i (t in the figure ₁ ) The counted message is forwarded through a first line (e.g. a wire line) for the next preset counting time t _i (t in the figure ₂ ) The counted message flows through the second line (e.gE.g. radio line) for a further next preset statistical moment t _i (t in the figure ₃ ) And forwarding the counted message flow through the first line, and so on until the message flow in the occurrence period of the message emergency is completely forwarded.

If the function is not conductive during the occurrence of the message incident, in another embodiment, the average value of the burst message quantity during the occurrence of the message incident is selected as the second average value (different from the first average value and without a corresponding size relationship, where "first" and "second" are used only as the distinction) and calculated according to the following formula:

wherein t is _s Expressed as the burst start time, t _e Expressed as the end time of the burst of the message stream, f (t _ξ ) Is the average value of the number of message flows during the occurrence of the message emergency.

In practice, one embodiment is according to f (t _ξ ) With each preset statistical time t _i Statistics of the number of associated messages f (t _i ) Is assigned to different transmission lines for forwarding. In particular, when f (t _i )≤f(t _ξ ) At the time, the preset statistical time t _i The associated message is forwarded via a first line (e.g., a wireline); when f (t) _i )＞f(t _ξ ) When the burst message quantity is divided into a first part and a second part, for f (t _i ) The number of the middle messages is less than or equal to f (t) _ξ ) Is forwarded via the first line for f (t _i ) The number of the messages in the message is greater than f (t) _ξ ) Is forwarded via a second line, e.g. a radio line. It should be noted that the allocation method is not the only division method, and it is only required to allocate the message flows during the occurrence of the message emergency to different lines for forwarding.

It should be noted that, the first line and the second line may be two wired lines, or two wireless lines, so long as the purpose of splitting the two lines can be achieved.

In addition, in the embodiment of the present application, after determining a line adopted by forwarding a burst packet, a Service class TOS (Type-of-Service) of an IP (Internet Protocol ) header of the packet may be modified to indicate a quality of Service expected by an upper layer protocol for processing a current datagram, and the data packet is allocated according to an importance level, so that the DSCP ((Differentiated Services Code Point, differential Service code point) value in an identification byte carries the determined line information.

By the method provided by the application, the problem that the existing one-line forwarding message cannot share and split the message load according to the time period and the current message quantity is solved. The method for forwarding the message load sharing and shunting can be carried out according to the time period and the current message quantity, and the multi-line forwarding of the burst message flow is realized, so that the message flow can be forwarded through a plurality of lines when the message flow quantity is larger and exceeds the average value, and the purpose of load sharing is achieved.

Based on the same inventive concept, the embodiment of the application also provides a burst message processing device, and because the principle of the device for solving the problem is similar to that of a burst message processing method, the implementation of the device can refer to the implementation of the method, and the repetition is omitted.
