Detailed Description
In order to more clearly illustrate the invention, the invention is further described below with reference to preferred embodiments and the accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.
It is noted that, in the description of the present application, relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
In the prior art, a communication system is described as an example of using three transmission channels for data transmission in an inquiry allocation manner, where the inquiry sequence includes a transmission channel 1, a transmission channel 2, and a transmission channel 3.
When the cache of a file to be transmitted is large, and the transmission channel 1, the transmission channel 2 and the transmission channel 3 all perform cache transmission of a part of the file, because transmission speed differences exist among the 3 transmission channels, the transmission channel 1 with the highest transmission speed completes transmission at first, and sends the next group of transmission data, while the transmission channel 3 with the lowest transmission speed performs transmission of the current file data, and the server can only wait for the transmission channel 3 with the lowest transmission speed, thereby causing a great delay problem.
When the cache of the file to be transmitted is small, the transmission speeds of the transmission channels 1-3 are fast, the transmission channel 1 quickly completes the current transmission task and then becomes a writable state again, and the transmission channel 1 is at the first position in the polling sequence, so that the transmission channel 1 is in the writable state after being sent when the communication system inquires every time. In this case, the transmission channel 1 is essentially single-path transmission, and the transmission channels 2 and 3 are supplementary transmissions when the transmission channel 1 is busy, which causes a great waste of bandwidth of the transmission channels 2 and 3. Even if the file to be transmitted is in a proper buffer memory size, once the network speed of each transmission channel fluctuates, the problem of bandwidth waste is caused.
And when the communication system adopts an average distribution mode to transmit the files by using three transmission channels, the cache of the files to be transmitted is averagely divided into a plurality of parts with the same number as the transmission channels, and the parts are respectively and successively transmitted to the transmission channels 1-3. In this working mode, when the network speeds of the transmission channels are not consistent, the transmission channel with the lowest speed will limit the transmission rate of the whole communication system. In addition, in this operation mode, there is a problem that bandwidth is wasted as in the above-described inquiry allocation method.
In order to solve the problems, the inventor proposes through a large number of theoretical researches and experiments that 1, all modules are sent in sequence as much as possible; 2. the waiting time is reduced as much as possible. On this basis, as shown in fig. 1, an embodiment of the present invention provides a bandwidth enhancing method, including:
s1: polling to judge whether an available transmission channel exists in at least two transmission channels, if not, controlling a waiting counter to add 1 and jumping to S1, and if so, distributing the transmission channels;
s3: transmitting data packets by using the distributed transmission channels, and controlling a transmission counter of the transmission channel to be increased by 1;
s5: according to the waiting value t of the waiting counter of the current transmissionmDynamically adjusting the buffer capacity size of the transmission channel, and storing the waiting value tmInitializing the waiting counter;
s7: judging whether the sum of the transmission times of the transmission counters of the transmission channels is larger than or equal to a preset transmission threshold value, if not, skipping to S1 to continue to transmit data, and if so, skipping to S9;
s9: and dynamically adjusting the buffer capacity size of each transmission channel according to the transmission times of each transmission channel, initializing the transmission counter of each transmission channel, and jumping to S1 to continue to transmit data.
The invention provides a bandwidth enhancing method aiming at the existing problems, on one hand, the buffer capacity of each transmission channel is dynamically adjusted by utilizing the transmission number ratio of each transmission channel recorded in the preset transmission number, on the other hand, the buffer capacity of each transmission channel is dynamically adjusted in real time by utilizing the recorded waiting number transmitted by each data packet, so that the buffer capacity is maximally matched according to the transmission speed of each transmission channel, thereby realizing the maximum utilization of the bandwidth of each transmission channel, reducing the waiting time for writing data in each transmission channel, effectively realizing the bandwidth enhancement, relieving the bandwidth waste, improving the overall transmission rate of a communication system and having wide application prospect.
In a specific embodiment, the number of the transmission channels is 3, and each transmission channel is a 5G communication module.
In this embodiment, a polling manner is adopted to query whether there is an available transmission channel, for example, when the bandwidth controller queries that the transmission channel 1 is in a writable state, the transmission channel 1 performs data transmission, then the bandwidth controller continuously queries whether the transmission channel 2 is writable according to a polling sequence, if writable, performs data transmission through the transmission channel 2, then the bandwidth controller continuously queries whether the transmission channel 3 is writable according to the polling sequence, and if writable, performs data transmission through the transmission channel 3. The bandwidth controller then makes the next round of polling inquiry. Specifically, the 3 transmission channels of this embodiment are recorded as socket1 a, transmission channel socket2b, and transmission channel socket3 c, and the buffer capacities of their corresponding buffer buffers are [ sizeA ], [ sizeB ], and [ sizeC ].
The socket1 a, the socket2B, and the socket 3C respectively represent the transmission times of each transmission channel recorded by the transmission counter, the transmission times of the socket1 is a, the transmission times of the socket2 is B, and the transmission times of the socket3 is C, the size represents the buffer capacity of the buffer of each transmission channel, and the sizeA, the B, and the sizeC represent the corresponding buffer capacities of A, B and C, respectively.
The waiting counter records the waiting time of the current transmission channel to wait for the value tmAnd (5) identifying. If the 3 transmission channels are all in transmission, which indicates that the data to be transmitted cannot be written into the transmission channel in transmission, waiting for the waiting value t of the countermSelf-adding until there is a transmission channel available.
In an optional embodiment, before the S1, the bandwidth enhancing method further includes:
and setting the buffer capacity of each transmission channel as a preset capacity threshold.
In this embodiment, the capacity threshold is preset for the buffer capacity, so as to ensure that the transmission channel can be used within a reasonable range.
Specifically, the buffer capacity can be expressed as: size is y x n + j, where n is the buffer factor, y is the number of bytes of the data packet, j is the number of bytes to be adjusted, and the byte j is then continued according to the waiting time tmThe buffer size is adjusted to change.
More specifically, if n is initialized to 48, y is initialized to 1000, and j is initialized to 0, the initial value of the buffer capacity may be: size 1000 × 48+ 0.
The bandwidth enhancing method of the present invention will now be described with a specific embodiment, as shown in fig. 1:
and S1, polling to judge whether there is available transmission channel in at least two transmission channels, if not, controlling the waiting counter to add 1 and jumping to S1, if yes, distributing the transmission channel.
The transmission channel 1, the transmission channel 2, and the transmission channel 3 are queried according to the polling sequence to determine whether there is a transmission channel to which transmission data can be written. Specifically, if all 3 transmission channels cannot be written in transmission during inquiry, the waiting value of the counter is incremented by 1, and polling judgment is continued. If writable transmission channels exist during inquiry, the transmission channel of the current inquiry is used as the transmission channel of the data to be transmitted.
S3: transmitting data packets by using the distributed transmission channels, and controlling a transmission counter of the transmission channel to be increased by 1;
if the currently writable transmission channel is the transmission channel 1, the transmission channel 1 is used to transmit the data packet, and the transmission times of the transmission counter a of the transmission channel 1, which represents the transmission times, are changed to a + 1. For example, when the inquiry of the 22 nd packet transmission data is performed, if the transmission numbers of the transmission channels 1 to 3 are 5, 8 and 8, respectively, then the inquiry is expressed as socket 15, socket 28 and socket 38, and when the bandwidth controller inquires the 22 nd packet transmission data, if the transmission channel 1 is in a writable state, the transmission channel 1 is changed to socket16, and the transmission numbers of the transmission channels 2 and 3 are not changed.
In this step, the number of times of transmission channels is recorded in real time to determine the relative operating state of each transmission channel. It can be understood that when the transmission times among the transmission channels are greatly different, it indicates that the transmission speed difference among the transmission channels is large.
S5: according to the waiting value t of the waiting counter of the current transmissionmDynamically adjusting the buffer capacity size of the transmission channel, and storing the waiting value tmAnd initializes the wait counter.
With each inquiry, each transmission counter respectively records the transmission times a, b and c corresponding to the transmission channels 1-3, and meanwhile, the waiting counter simultaneously records the waiting value t of the transmission channel for the current transmission before transmitting datamAnd by waiting for the value tmTo adjust the transmission in real timeCurrent buffer size of input channelm。
E.g. a waiting value t when transmitting this timemAt time 3, the waiting value of the transmission is recorded in the register of the transmission channel so as to adjust the buffer capacity of the transmission channel subsequently, and the waiting value of the waiting counter is initialized, i.e. the waiting value is cleared by 0 so as to record the waiting time of the transmission.
In an alternative embodiment, as shown in fig. 2, the S5 further includes:
s51: judging the waiting value t of the waiting counter of the transmissionmWhether the value is greater than a preset first waiting threshold value t-s1If yes, storing the buffer capacity size of the current transmission channelmAnd adjusting the buffer capacity size of the transmission channel by using a preset first capacity ratiom+1Otherwise, go to S53.
In this step, when waiting for the value tmIs greater than a preset first waiting threshold value t-s1When the buffer capacity size of the transmission channel is required to be reducedmIn this embodiment, the buffer capacity of the transmission channel is adjusted to size by using the preset first capacity ratiom+1So that the adjusted buffer capacity size of the conventional channelm+1Size of original buffermThe number of the queries is reduced, so that the time delay of the next query is reduced, the transmission rate of the transmission channel is improved, the balance and stability among all the transmission channels are further improved, and the transmission rate of all the transmission channels is maximized.
In one particular example, the first capacity ratio is 0.99.
S53: judging the waiting value t of the waiting counter of the transmissionmWhether the value is less than or equal to a preset first waiting threshold value t-s1And is greater than a preset second waiting threshold t-s2If yes, storing the buffer capacity size of the current transmission channelmAnd adjusting the buffer capacity of the transmission channel by using a preset first step value, and otherwise, jumping to S55.
When the waiting value t of the waiting counter of the current transmissionmLess than a predetermined first waitThreshold value t-s1Then, it indicates the waiting time t before the transmission channel is written with the transmission datamVery short, at the same time, will wait for the value tmAnd a second waiting threshold t-s2Comparing to determine a wait value tmAccording to the waiting value t in different rangesmBuffer capacity size of the current transmission channelmAdjustment in different ways.
Specifically, while waiting for the value tmLess than or equal to a preset first waiting threshold value t-s1And is greater than a preset second waiting threshold t-s2When is, i.e. t-s2＜tm＜t-s1Then, the buffer capacity size of the current transmission channel is storedmAnd adjusting the buffer capacity of the transmission channel by using a preset first step value.
In one specific example, the second wait threshold t-s2The value is 0, a first further value is preset to be 1, and since size is y × n + j, when the buffer size of the current transmission channel is equal to sizemAdjusted size 'according to preset first stepping value plus 1'mY n + (j +1)), the number j of bytes to be adjusted increases with increasing preset first step value.
In this step, by the pair t-s2＜tm＜t-s1Buffer capacity size of current transmission channel of timemAnd gradually increasing and adjusting to ensure that the transmission speed of the transmission channel can be balanced with the buffer capacity of the transmission channel, so as to ensure the maximization of the transmission speed.
S55: judging the waiting value t of the waiting counter of the transmissionmWhether the value is less than or equal to a preset second waiting threshold value t-s2If yes, according to the waiting value t of the previous transmission of the transmission channelm-1Dynamically adjusting the buffer size of the transmission channelm。
When the waiting value t of the waiting counter of the current transmissionmNot only is smaller than the first waiting threshold t-s1And is also less than or equal to a second waiting threshold t-s2When, i.e., tm≤t-s2＜t-s1At this time, it is described that the transmission speed of the transmission channel is fast, and the transmission channel can be used for transmitting dataQuickly finishing the size of the current cache capacitymTherefore, the buffer capacity of the transmission channel can be increased to match the transmission speed, so that the balance between the transmission speed and the buffer capacity is realized, and the maximization of the transmission rate is ensured.
In one specific example, the second wait threshold t-s2Is 0, i.e. tmIs less than or equal to 0, at this moment, the waiting time t of the current transmission channel is describedmHas already been equal to 0, at this point, according to the waiting value t of the previous transmission of the transmission channelm-1And judging how to adjust the buffer capacity to further dynamically adjust the buffer capacity of the transmission channel, namely repeatedly searching for the optimal value of the buffer capacity of the transmission channel.
In an alternative embodiment, as shown in fig. 2, the S55 further includes:
s551: judging the waiting value t of the previous transmission of the transmission channelm-1Whether the threshold value is larger than a preset second waiting threshold value t-s2If so, go to S553, otherwise, go to S555.
In this step, the waiting value t for the previous transmission of the transmission channel is passedm-1And a second waiting threshold t-s2Compared with the prior art, the transmission state of the transmission channel can be judged more accurately.
S553: storing the buffer capacity size of the current transmission channelmSetting the buffer capacity of the transmission channel as the buffer capacity size of the previous transmission of the transmission channelm-1；
In this step, if the second waiting threshold t-s2If the value is 0, that is, the waiting time delay of the current transmission channel is 0, the waiting value t of the previous transmission of the transmission channel is utilizedm-1Judging, if it is greater than the second waiting threshold 0, i.e. tm-1When the buffer size is larger than 0, the previous buffer size of the transmission channel is shownmSmall size, high transmission speed, and small buffer sizemNot matched to the transmission speed. Therefore, the buffer capacity size of the current transmission channel is setmSet as the buffer size at the previous transmissionm-1Can more accurately judge the transmission of the transmission channelAnd the state is adjusted in real time according to the buffer capacity of the transmission channel.
The buffer capacity size of the current transmission channel is measuredm+1Is set to sizem-1When the next data transmission is carried out, the optimal cache capacity of the transmission channel can be further searched, so that the bandwidth is enhanced, the delay is reduced, the bandwidth waste is relieved, in addition, as the adjacent transmission data sequentially reach the server, the delay of the whole communication system is also reduced, and the whole transmission rate of the communication system is improved.
S555: storing the buffer capacity size of the current transmission channelmAnd adjusting the buffer capacity of the transmission channel by using a preset second capacity ratio.
In this step, if the second waiting threshold t-s20, the waiting value t of the previous transmission of the transmission channelm-1Less than or equal to a second waiting threshold of 0, i.e. tm-10 or less, and tm≤0＜t-s1At this time, it is described that the buffer capacity of the transmission channel is small and the transmission speed is fast, that is, the network transmission speed of the transmission channel is not fully utilized, the buffer capacity is not matched with the buffer speed, and the buffer capacity size of the transmission channel needs to be performedmAnd (4) adjusting.
In a specific example, the preset second capacity ratio is 1.05, and the adjusted buffer capacity size of the transmission channelm+1Become sizem1.05, the buffer capacity of the transmission channel is increased, the buffer capacity of the transmission channel is dynamically adjusted in real time to be adaptive to the transmission speed of the transmission channel, and the bandwidth of the transmission channel is utilized to the maximum extent.
In this embodiment, the buffer capacity of the transmission channel is adjusted according to the waiting value of the waiting time of transmitting the data packet in each transmission channel, and specifically, the adjustment process of the buffer capacity may be represented as: size ═ 0.99 (y × n + j) ×d*1.05e+ f, where size (y × n + j) represents the current buffer capacity of the transmission channel, and d represents the wait value tmIs greater than a first waiting threshold t-s1E represents a wait value tmIs less than or equal to a second waiting threshold t-s2F denotes the wait value tmIs less than a first waiting threshold t-s1Wait for the value tmAnd is greater than a second waiting threshold t-s2The step value of the adjustment. For example, waiting for the value t this timemIs greater than a first waiting threshold t-s1If d is 1, e is 0, and f is 0, the buffer size of the next transmission channel is (y × n + j) × 0.991*1.050+0＝(y*n+j)*0.99。
Therefore, the embodiment of the invention waits for the value t for each time of the transmission channelmAnd by waiting for a value tmThe judgment of the specific value range can determine the transmission state of the current transmission channel, so that the buffer capacity of the transmission channel is adjusted in real time to realize the balance matching of the buffer capacity and the transmission speed, and the transmission channel writes a waiting value t of transmission datamAnd the data transmission is realized by each transmission channel according to the polling sequence, so that the time delay is reduced, and the transmission rate of the whole system can be improved.
S7: and judging whether the sum of the transmission times of the transmission counters of the transmission channels is greater than or equal to a preset transmission threshold value, if not, jumping to S1 to continue to transmit data, and if so, jumping to S9.
When the accumulated transmission times of all the transmission channels are within the preset threshold value, the buffer capacity size of the currently transmitted transmission channel is adjusted in real time through waiting time in the previous stepmBuffer size per transmission channelmWaiting value t with itselfmAnd adjusting, namely fine-adjusting the buffer capacity of each transmission channel to enable the transmission speed of each transmission channel to be optimally matched with the buffer capacity of the transmission channel, so that the transmission rate of the transmission channel is maximized.
In this step, when the accumulated transmission times of all the transmission channels is greater than or equal to the preset threshold, the overall working state of the transmission channels can be judged through the transmission times of each transmission channel recorded by the transmission counter.
In a specific example, the preset threshold is 100, and the cumulative transmission times of all the transmission channels 1 to 3 is 100 packets, where the transmission channel 2 transmits 30 data packets, and the transmission channel 3 transmits 20 data packets, which can be represented as:
the buffer capacity when the transmission channel 1 transmits 50 data packets is as follows: socket 150 [1024 × 48 ];
the buffer capacity when the transmission channel 2 transmits 30 data packets is as follows: socket 230 [1024 × 48 ];
the buffer capacity when the transmission channel 3 transmits 20 data packets is as follows: socket 320 [1024 × 48 ].
When the accumulated transmission times of all the transmission channels are greater than or equal to the preset threshold value 100, the transmission channel 1 has the most transmission times among the 3 transmission channels, the transmission rate is the fastest, and the transmission channel 3 has the least transmission times among the 3 transmission channels, and the transmission rate is the slowest. Within the preset threshold, each transmission channel already shows the difference of different transmission rates, so that the overall adjustment of all the transmission channels after exceeding the accumulated times is realized by setting the preset threshold, namely the coarse adjustment of the buffer capacity of each transmission channel is realized.
S9: and dynamically adjusting the buffer capacity of each transmission channel according to the transmission times of each transmission channel, initializing the transmission counter of each transmission channel, and jumping to S1 to continue to transmit data.
Further, as can be seen from the transmission times of the 3 transmission channels and the corresponding buffer capacity, the transmission channel 1 has the best current transmission effect, and the transmission channel 3 has the worst current transmission effect. In order to realize the maximum utilization of the transmission channel 1 in all the transmission channels and the adjustment of the transmission rate of the transmission channel 3, the transmission times of all the transmission channels can be recorded and judged, and the transmission proportion of each transmission channel in all the transmission channels can be adjusted, so that the integral transmission stability of all the transmission channels is realized, and the integral transmission rate is greatly improved.
In an alternative embodiment, as shown in fig. 3, the S9 further includes:
s91: determining the maximum value and the minimum value of the transmission times in each transmission channel;
s93: judging whether the difference value between the maximum value and the minimum value is smaller than a preset difference value threshold k, if so, initializing the transmission counters of the transmission channels, and jumping to S1 to continue to transmit data, otherwise, jumping to S95;
s95: and adjusting the buffer capacity of the corresponding transmission channel according to the ratio of the transmission times of each transmission channel to the minimum value, initializing the transmission counter of each transmission channel, and jumping to S1 to continue to transmit data.
In this embodiment, the maximum number of transmission times and the minimum number of transmission times are utilized to perform the specific gravity adjustment of the buffer capacity of each transmission channel in all the transmission channels, so that the buffer capacity of each transmission channel is matched with the transmission speed of the transmission channel to achieve the maximized performance, the transmission rate of each transmission channel is maximized, the broadband waste of each transmission channel is reduced, the overall transmission rate of the communication system is improved, and the overall stability of the communication system is effectively improved.
In one embodiment, as can be seen from the foregoing, the minimum number of transmissions in the 3 transmission channels is 20, i.e., Min { a, b, c } ═ 20; the maximum number of transmissions in the 3 transmission channels is 50, i.e., Max { a, b, c } — 50.
The preset difference threshold k is 3, Max { a, b, c } -Min { a, b, c }, 50-20 ═ 30 >3, and the maximum value and the minimum value of the transmission times are greater than the preset difference threshold, so that a transmission channel with a large transmission rate difference exists in the 3 transmission channels, and the buffer capacity of each transmission channel needs to be adjusted.
Since the buffer capacity is: size ═ y × n + j, where n is the buffer factor, y is the number of bytes of the packet, j is the number of bytes to be adjusted, and byte j is then changed by adjusting the buffer size according to the waiting time tm. When n is 48 and y is 1024, the buffer capacity of each adjusted transmission channel buffer can be expressed as:
transmission channel 1: socket 150 ═ 1024 × 48 (50/20) + j;
the transmission channel 2: socket 230 ═ 1024 × 48 (30/20) + j;
the transmission channel 3: socket 320 ═ 1024 × 48 × (20/20) + j.
It can be known that, namely, the buffer capacity of each transmission channel is adjusted by adjusting the buffer factor, in this embodiment, since the transmission rate of the transmission channel 1 is higher, the buffer capacity corresponding to the adjusted transmission channel 1 is increased more, and the buffer capacity in all the transmission channels is the largest, the faster transmission speed is adapted to the larger buffer capacity, the transmission rate of the transmission channel is maximized, and the bandwidth is utilized to the maximum. The transmission channel 2 and the transmission channel 3 respectively adjust the relative cache capacity, and the maximum setting of the cache capacity under the transmission speed of the transmission channel is realized, so that the overall transmission rate of the communication system is improved, and the overall stability of the communication system is effectively improved.
In this embodiment, the transmission times of each transmission channel are used to compare the buffer capacity of each transmission channel for coarse adjustment, and the waiting value of each transmission channel is used to fine-adjust the buffer capacity of each transmission channel in real time, so that the communication system is in an ideal state: when a group of data just before the transmission of the transmission channel 1 is finished becomes writable, and the inquiry of the current transmission data by the bandwidth controller arrives at the same time, the waiting time for transmitting the data packet by using the transmission channel 1 is short, and in this case, the transmission channel 1 can transmit the data uninterruptedly. When the bandwidth controller inquires the transmission channel 1 and writes in the transmission channel 2 after the completion, the transmission channel 2 just transmits the last group of data to be in a writable state, the bandwidth controller simultaneously arrives at the current transmission inquiry, the waiting time for transmitting the data packet by using the transmission channel 2 is short, and the transmission channel 2 can transmit the data uninterruptedly. Therefore, the polling sequence of the bandwidth controller is consistent with the allocation sequence of the actual transmission channels, and is 1- >2- >3- >1- >2- >3 … …, in this case, the bandwidth of each transmission channel can be utilized to the maximum extent, the waste of bandwidth is effectively reduced, and the time delay of the whole communication system is reduced because the adjacent transmission data sequentially reach the server, and the overall transmission rate of the communication system is improved.
Corresponding to the bandwidth enhancement method provided by the foregoing embodiment, as shown in fig. 4, an embodiment of the present application further provides a communication system applying the bandwidth enhancement method, including: at least two transmission channels, a waiting counter and a bandwidth controller, wherein
Each transmission channel comprises a transmission counter for recording the transmission times of the transmission channel;
the waiting counter is used for recording the waiting time of one transmission;
the bandwidth controller is configured to:
s1: polling to judge whether an available transmission channel exists in at least two transmission channels, if not, controlling a waiting counter to add 1 and jumping to S1, and if so, distributing the transmission channels;
s3: transmitting data packets by using the distributed transmission channels, and controlling a transmission counter of the transmission channel to be increased by 1;
s5: dynamically adjusting the cache capacity of the transmission channel according to the waiting value of the waiting counter of the current transmission, storing the waiting value and initializing the waiting counter;
s7: judging whether the sum of the transmission times of the transmission counters of the transmission channels is larger than or equal to a preset transmission threshold value, if not, skipping to S1 to continue to transmit data, and if so, skipping to S9;
s9: and dynamically adjusting the buffer capacity of each transmission channel according to the transmission times of each transmission channel, initializing the transmission counter of each transmission channel, and jumping to S1 to continue to transmit data.
The invention provides a communication system applying the bandwidth enhancing method aiming at the existing problems, on one hand, the buffer capacity of each transmission channel is dynamically adjusted by utilizing the transmission number ratio of each transmission channel recorded in the preset transmission number, on the other hand, the buffer capacity of each transmission channel is dynamically adjusted in real time by utilizing the recorded waiting number transmitted by each data packet, so that the buffer capacity is maximally matched according to the transmission speed of each transmission channel, thereby realizing the maximum utilization of the bandwidth of each transmission channel, reducing the waiting time for writing data in each transmission channel, effectively realizing the bandwidth enhancement, relieving the bandwidth waste, improving the overall transmission rate of the communication system and having wide application prospect.
In an optional embodiment, the number of the transmission channels is 3, and each transmission channel is a 5G communication module.
Specifically, the bandwidth controller performs inquiry of each transmission channel before data transmission in a polling manner, and if the transmission channels 1 to 3 are all transmitting, the waiting times recorded by the waiting counter are increased by 1, and the inquiry of all the transmission channels in the next round is performed in the current polling sequence. If the transmission channel 1 can be used, the bandwidth controller uses the transmission channel 1 to transmit the data packet, and controls the transmission times recorded by the transmission counter of the transmission channel 1 to be added with 1. Meanwhile, the waiting counter records the waiting time length before the transmission channel 1 of the current transmission data writes data as a waiting numerical value. The bandwidth controller dynamically adjusts the buffer capacity of the transmission channel 1 according to the waiting value, and reduces the waiting time before data is written into the transmission channel.
The bandwidth controller records the transmission times through the transmission counters 1-3 of the transmission channels 1-3, adjusts the buffer capacity of each transmission channel according to the transmission time ratio of each transmission channel, enables the transmission speed of each transmission channel to be matched with the buffer capacity to the maximum, and enables the buffer capacity of each transmission channel to be relatively balanced with the buffer capacity of other transmission channels by dynamically adjusting the buffer proportion of each transmission channel relative to the buffer capacity of all the transmission channels, so that the bandwidth of each transmission channel is maximally utilized, the bandwidth waste is effectively reduced, the waiting time of each transmission channel is reduced, the time delay is reduced, and the bandwidth controller has a wide application prospect.
