The following describes an exemplary data stream transmission method according to an embodiment of the present invention with reference to the accompanying drawings:
The data stream transmission method, the data stream transmission device, the network equipment and the storage medium provided by the embodiment of the invention can be applied to a data stream transmission system. As shown in fig. 1, the data stream transmission system includes a terminal 101, a terminal 102, a terminal 103, a terminal 104, a terminal 105, a terminal 106, a network device 107, a network device 108, a network device 109, a network device 110, a network device 111, a network device 112, and a network device 113.

The data stream transmission system shown in fig. 1 further includes links 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12. In an embodiment of the present invention, the data information of each of the plurality of data streams may include a transmission path of the data stream, and in particular, the transmission path of one data stream may be composed of a plurality of links shown in fig. 1. For example, the transmission path of a certain data stream may consist of link 1, link 2, link 3 and link 4, i.e. the data stream may be sent from terminal 101 to terminal 104 via network device 107, network device 108 and network device 109, respectively.
It should be noted that the 6 terminals, 7 network devices, and 12 links shown in fig. 1 are an example of the embodiment of the present invention. The number of the above-mentioned devices and the number of links between the devices are not particularly limited in the embodiments of the present invention.

Specifically, the data stream input module is configured to input a plurality of data streams to be sent (or to be transmitted).

The queue resource allocation module is configured to add the plurality of data flows to the corresponding queues, and may also be understood as allocating queue resources of the corresponding queues to the plurality of data flows. Specifically, the queue resource allocation module may add at least two data flows to the target queue, that is, allocate the queue resources of the target queue to the at least two data flows; and the queue resource allocation module may also add at least one data stream (i.e., a data stream of the plurality of data streams other than the at least two data streams) to the other queue, i.e., allocate queue resources of the other queue to the at least one data stream.
The data stream output module is configured to output (also understood as transmitting or sending) the plurality of data streams. Specifically, the data stream output module may send the at least two data streams based on the target queue and send the at least one data stream based on the other queue.
Optionally, the network device further includes a data stream recording module and a timeslot resource allocation module.

The timeslot resource allocation module is configured to determine a transmission time of each of the plurality of data streams, and may also be understood as allocating timeslot resources to each of the plurality of data streams at the transmission time of each of the plurality of data streams. Specifically, when the timeslot resource allocation module determines to transmit a first data stream at a first time and transmit a second data stream at a second time, the timeslot resource allocation module may allocate timeslot resources for the first data stream at the first time and allocate timeslot resources for the second data stream at the second time.
As shown in fig. 3, the data stream transmission method provided by the embodiment of the present invention may include S101-S104.
S101, the network equipment acquires data information of a plurality of data streams.
Wherein the data information of a data stream comprises an identification of the data stream and a transmission path of the data stream.
It should be appreciated that a transmission path of a data stream may include a source node, a destination node, at least one network device, and at least two links, the transmission path being used to characterize the path of the data stream transmitted from the source node to the destination node. In particular, the data stream may be sent from the source node via the at least one network device (also understood as an intermediate node) and the at least two links to the destination node.
Illustratively, in connection with fig. 1, taking a certain data stream (e.g., a first data stream) of the plurality of data streams as an example, a source node included in a transmission path of the first data stream may be a terminal 101, a destination node may be a terminal 104, at least one network device included in the transmission path of the first data stream is a network device 107, a network device 108, and a network device 109, and at least two links included in the transmission path of the first data stream are a link 1, a link 2, a link 3, and a link 4.
Alternatively, the network device in the embodiment of the present invention may be a device having a data forwarding function, such as a switch.
S102, the network equipment determines the types of the data streams according to the identifiers of the data streams.
It will be appreciated that an identification corresponds to a type. For any one of the plurality of data streams, after acquiring the identifier of the data stream, the network device may determine the type corresponding to the identifier, and determine the type as the type of the data stream.
By way of example, the type of one data stream may be a time sensitive data stream, an audio video data stream, or a normal data stream, etc.
S103, the network equipment adds at least two data streams to the target queue.
The at least two data streams are data streams of the same type in the plurality of data streams, and the similarity between the transmission path of a first data stream and the transmission path of a second data stream is greater than or equal to a similarity threshold, wherein the first data stream is one of the at least two data streams, and the second data stream is a data stream of the at least two data streams except the first data stream.
It should be understood that the similarity between the transmission path of the first data stream (hereinafter referred to as the first transmission path) and the transmission path of the second data stream (hereinafter referred to as the second transmission path) is used to characterize the similarity between the first transmission path and the second transmission path. Specifically, when the similarity between the first transmission path and the second transmission path is greater than or equal to the similarity threshold, the first transmission path and the second transmission path are indicated to be more similar; otherwise, when the similarity between the first transmission path and the second transmission path is smaller than the similarity threshold, the first transmission path and the second transmission path are indicated to have larger difference.
In an alternative implementation, the similarity between the first transmission path and the second transmission path is a ratio between a number of links included in a preset intersection, which is an intersection between a set of links included in the first transmission path (hereinafter referred to as a first link set) and a set of links included in the second transmission path (hereinafter referred to as a second link set), and a number of links included in a preset union, which is a union between the first link set and the second link set.
In the embodiment of the present invention, the types of the data streams in the at least two data streams are the same, which is also understood as that the identifiers of the data streams are the same. And, the similarity between transmission paths of any two data streams in the at least two data streams is greater than or equal to a similarity threshold.
It will be appreciated that the network device may determine the at least two data streams from the plurality of data streams (the types of the respective data streams in the at least two data streams are the same, and the similarity between transmission paths of any two data streams in the at least two data streams is greater than a similarity threshold). Further, the network device may add the at least two data streams to the target queue.
In the embodiment of the present invention, the network device adds the at least two data streams to the target queue, which can be understood as adding at least two data streams with the same type and a transmission path similarity greater than or equal to a similarity threshold to the same queue, because in the related art, when the switch needs to transmit a plurality of time-sensitive data streams, the switch preferentially allocates a queue for each time-sensitive data stream in the plurality of time-sensitive data streams, and occupies excessive queue resources; in the embodiment of the invention, one queue may include (or exist) at least two data streams, so that when the network device sends at least two data streams based on one queue, the use efficiency of the queue resources can be improved.
For example, the type of each of the at least two data streams included in the target queue may be a time sensitive data stream, i.e. the network device may add the at least two time sensitive data streams to the same queue.
Alternatively, a plurality of queues may be stored in the network device, and the target queue is one of the plurality of queues. After the network device determines to add the at least two data flows to the target queue, the network device may further determine to add at least one data flow to another queue, the at least one data flow being a data flow other than the at least two data flows in the plurality of data flows, the other queue being a queue other than the target queue in the plurality of queues.
S104, the network equipment transmits at least two data streams based on the target queue.
It should be understood that the network device sends the at least two data flows based on the target queue, that is, sends (or transmits) the at least two data flows included in the target queue to a next device (e.g., a next network device or destination node) in connection with the network device.
The technical scheme provided by the embodiment at least has the following beneficial effects: as known from S101-S104, the network device may acquire data information of a plurality of data flows, and since the data information of one data flow includes an identifier of the data flow and a transmission path of the data flow, the network device may determine at least two data flows with the same type from the plurality of data flows, and a similarity between the transmission paths is greater than or equal to a similarity threshold; the network device may then add the at least two data streams to a target queue and send the at least two data streams based on the target queue. In the invention, the network device can add at least two data streams with the same type and similar transmission paths (namely, the similarity is greater than or equal to the similarity threshold value) to the same queue (namely, the target queue), and based on the transmission (or transmission) of the at least two data streams by the same queue, the at least two data streams can be transmitted by using the queue resources of the same queue, so that the use efficiency of the queue resources can be improved.
Referring to fig. 3, as shown in fig. 4, the data stream transmission method provided in the embodiment of the present invention further includes S105-S106.
S105, the network device determines the first number and the second number.
The first number is the number of links included in a preset intersection, the preset intersection is the intersection of a first link set and a second link set, the first link set is the set of links included in a first transmission path, the second link set is the set of links included in a second transmission path, the first transmission path is the transmission path of the first data stream, the second transmission path is the transmission path of the second data stream, the second number is the number of links included in a preset union, and the preset union is the union of the first link set and the second link set.
It should be appreciated that when the network device acquires the first transmission path and the second transmission path, each link included in the first transmission path and each link included in the second transmission path may be determined. The network device may then determine the first set of links and the second set of links based on each link included in the first transmission path and each link included in the second transmission path. The network device may then determine the preset intersection set based on the first link set and the second link set, which may be specifically understood as determining X links (x≡0) that are simultaneously present in the first link set (or the first transmission path) and the second link set (or the second transmission path), and may determine the number of links included in the preset intersection set (i.e., the number of X links) as the first number.
In the embodiment of the present invention, the first number may also be understood as the number of links included in the first transmission path (or the number of links included in the second transmission path) that are the same as those in the first transmission path.
In addition, the network device may further determine the preset union set based on the first link set and the second link set, and determine the number of links included in the preset union set as the second number.
S106, the network equipment determines the ratio between the first number and the second number as the similarity between the first transmission path and the second transmission path.
For example, in combination with fig. 1, assuming that the first link set includes link 1, link 2, link 3, and link 4, and the second link set includes link 5, link 2, link 3, and link 4, the network device may determine that the preset intersection includes link 2, link 3, and link 4, and preset and centralized includes link 1, link 2, link 3, link 4, and link 5, the network device determines that the first number is 3, the second number is 5, and a similarity between the first transmission path and the second transmission path is 0.6.
Further, assuming that the similarity threshold is 0.5, the network device determines that the similarity between the first transmission path and the second transmission path is greater than the similarity threshold.
In an alternative implementation, the data information of a data stream may not include the transmission path of the data stream, and the data information of the data stream may also include the destination address of the data stream. After the network device obtains the destination address of the data stream, the network device may determine a transmission path of the data stream from at least one transmission path corresponding to the destination address. In particular, the network device may determine a transmission path with the smallest load (which may also be understood as the largest remaining bandwidth) of the at least one transmission path as the transmission path of the data stream.
Further, after determining the transmission path of each of the plurality of data streams, the network device may determine a similarity between the transmission path of each data stream and the transmission paths of the second other data streams, and further determine the at least two data streams from the plurality of data streams.
Referring to fig. 3, as shown in fig. 5, in an implementation manner of the embodiment of the present invention, at least two data flows are added to the target queue in S103, which may specifically include S1031-S1032.
S1031, the network device determines the transmission sequence of at least two data streams.
In an alternative implementation, the network device may determine the transmission order of the at least two data streams according to the priority of each of the at least two data streams and/or the reception time of each of the at least two data streams. Wherein the time of receipt of a data stream is used to characterize the time at which the data stream was received by the network device.
In one case, when the priority of the first data stream is higher than the priority of the second data stream, the network device may determine to transmit the first data stream preferentially, that is, the transmission order of the second data stream is subsequent to the transmission order of the first data stream.
In another case, when the reception time of the first data stream is before the reception time of the second data stream, the network device may determine to preferentially transmit the first data stream, i.e., the transmission order of the second data stream is after the transmission order of the first data stream.
In another case, when the priority of the first data stream is the same as the priority of the second data stream (or the reception time of the first data stream is the same as the reception time of the second data stream), the network device may determine whether the reception time of the first data stream is before the reception time of the second data stream (or whether the priority of the first data stream is higher than the priority of the second data stream). When the reception time of the first data stream is before the reception time of the second data stream (or the priority of the first data stream is higher than the priority of the second data stream), the network device may determine to transmit the first data stream preferentially, i.e., the transmission order of the second data stream is after the transmission order of the first data stream.
S1032, the network device adds at least two data streams to the target queue according to the transmission sequence of the at least two data streams.
In the embodiment of the present invention, the network device adds the at least two data streams to the target queue according to the transmission sequence of the at least two data streams, which can be understood that the network device preferentially adds the data stream with the earlier transmission sequence of the data stream to the target queue.
For example, as shown in fig. 6, it is assumed that the at least two data streams include 3 data streams, specifically, data stream 1, data stream 2, and data stream 3, where the priority of data stream 1 is higher than the priority of data stream 2, and the priority of data stream 2 is higher than the priority of data stream 3. The network device determines that the transmission order of the 3 data streams is data stream 1, data stream 2 and data stream 3 in sequence, and the network device adds the 3 data streams to the target queue according to the transmission order of the 3 data streams, specifically, the network device adds the data stream 1 to the target queue, then adds the data stream 2 to the target queue, and finally adds the data stream 3 to the target queue.
In an alternative implementation, after the network device adds the at least two data to the target queue according to the transmission order of the at least two data flows, the at least two data flows may be further sent according to the transmission order.
Referring to fig. 3, as shown in fig. 7, in an implementation manner of the embodiment of the present invention, the data information of one data stream further includes the data size of the data stream and the transmission period of the data stream, and the data stream transmission method provided by the embodiment of the present invention further includes S107.
And S107, the network equipment determines the corresponding processing time length of each data stream according to the data volume of each data stream in at least two data streams and the preset processing rate.
It should be understood that, for each data stream, the network device may determine a ratio of the data size of each data stream to the preset processing rate as a processing duration corresponding to each data stream. The data size of a data stream can also be understood as the load of the data comprised in the data stream.
In an alternative implementation, the preset processing rate may be a processing rate of the network device. The preset processing rate may be, for example, 100Mbps, 1000Mbps, or 1Gbps.
Continuing with FIG. 7, the sending at least two data streams based on the target queue specifically includes S1041.
S1041, when the transmission period of the current data stream is the same as the transmission period of the next data stream, and the current data stream is transmitted at the first time in the preset transmission period, the network device transmits the next data stream at the second time in the preset transmission period.
The current data stream is one of the at least two data streams, the time interval between the first time and the second time is a preset time length, the preset time length is a processing time length corresponding to the current data stream, the preset transmission period is one of M transmission periods corresponding to the next data stream, and M is more than or equal to 1.
It will be appreciated that the transmission period of a data stream is used to characterize the transmission of the data stream once per a predetermined period of time. For example, assuming a transmission period of 100 μs (microseconds), this means that the data stream is transmitted once every 100 μs interval.
It will be appreciated that the transmission order of the current data stream is adjacent to the transmission order of the next data stream, and that the transmission order of the next data stream is subsequent to the transmission order of the current data stream. After the network device obtains the data size of the current data stream, the network device may combine the preset processing rate to determine the processing duration corresponding to the current data stream (i.e., the preset duration).
In the embodiment of the present invention, M transmission periods corresponding to a next data stream are used to characterize that the network device needs to transmit the next data stream in each transmission period of the M transmission periods. For the current data stream, the network device may transmit the current data stream in each of the Y transmission periods corresponding to the current data stream, where Y is greater than or equal to 1. The length of time characterized by each of the M transmission periods (i.e., the transmission period of the next data stream) is the same as the length of time characterized by each of the Y transmission periods (i.e., the transmission period of the current data stream), and the sizes of M and Y may be the same or different.
When the transmission period of the current data stream is the same as the transmission period of the next data stream, it is indicated that the network device should transmit (or send) the current data stream and the next data stream within a certain preset time period (e.g., a preset transmission period) characterized by the transmission period of the current data stream (or the transmission period of the next data stream). And the processing duration corresponding to the current data stream may be spaced between the transmission time of the current data stream (i.e. the first time) and the transmission time of the next data stream (i.e. the second time), specifically, the network device sends the current data stream at the first time, and sends the next data stream at the second time spaced from the first time by the preset duration after the first time.
Alternatively, the preset duration may be understood as a time offset of the second time with respect to the first time.
As shown in fig. 8, it is assumed that the at least two data streams include a data stream 1, a data stream 2, and a data stream 3, where the data stream 1 has a data size of 3000 bytes, the data stream 1 has a transmission period of 200 μs, the data stream 2 has a data size of 1500 bytes, the data stream 2 has a transmission period of 100 μs, the data stream 3 has a data size of 1500 bytes, and the data stream 3 has a transmission period of 100 μs. Assuming that the preset processing rate is 1000Mbps, the network device determines that the processing duration corresponding to the data stream 1 is 24 μs, the processing duration corresponding to the data stream 2 is 12 μs, and the processing duration corresponding to the data stream 3 is 12 μs.
Assuming that the transmission period 1, the transmission period 2, and the transmission period 3 shown in fig. 8 belong to the above M transmission periods, since the transmission period of the data stream 2 is the same as the transmission period of the data stream 3 (i.e., all are 100 μs), and further assuming that the network device determines that the data stream 2 is transmitted at time t1 in the transmission period 1, the network device determines that the data stream 3 is transmitted at time t2 in the transmission period 1, and the time interval between the time t1 and the time t2 is the processing duration (i.e., 12 μs) corresponding to the data stream 2. Similarly, when the network device determines that the data stream 2 is transmitted at time t3 in the transmission period 2 (or determines that the data stream 2 is transmitted at time t6 in the transmission period 3), the network device determines that the data stream 3 is transmitted at time t4 in the transmission period 2 (or determines that the data stream 3 is transmitted at time t7 in the transmission period 3), and specifically, a time interval between the time t3 and the time t4 (or a time interval between the time t6 and the time t 7) is also a processing duration (i.e., 12 μs) corresponding to the data stream 2.
In an alternative implementation, the transmission periods of the respective data streams of the at least two data streams may also be different. When the transmission periods of the respective data streams are different, the network device may determine a transmission super period corresponding to the respective data streams of the at least two data streams, and the transmission super period may be a minimum integer multiple of the transmission period of the respective data streams of the at least two data streams.
For example, in combination with the example in fig. 8, the transmission super-period 1 shown in fig. 8 is a transmission super-period corresponding to the 3 data streams, and the time length represented by the transmission super-period 1 is 200 μs. It should be appreciated that since the transmission supersycle 1 characterizes a same length of time as the transmission cycle of data stream 1 and the transmission supersycle 1 characterizes a length of time that is 2 times the transmission cycle of data stream 2 (or data stream 3), the network device may determine to transmit 1 data stream 1 in 1 transmission supersycle (e.g., transmission supersycle 1) corresponding to data stream 1, specifically may transmit the data stream 1 in the transmission cycle 1, and not transmit the data stream 1 in the transmission cycle 2. In addition, since the transmission period 3 belongs to a time interval characterized by a next transmission super period (the next transmission super period is not fully shown in fig. 8) corresponding to the transmission super period 1, the network device may also transmit the data stream 1 in the transmission period 3.
Assuming that the data stream 1 is the first of the at least two data streams (which may also be understood as requiring the first data stream to be sent from the network device), the network device may determine that the data stream 1 is sent at time t0 in the transmission period 1 (which may also be understood as the first time in the transmission period 1), and the time interval between the time t0 and the time t1 is the processing duration (i.e. 24 μs) corresponding to the data stream 1. Similarly, the network device may also determine that the data stream 1 is transmitted at time t5 in the transmission period 3 (i.e. the first time in the transmission period 3), where the time interval between the time t5 and the time t6 is the processing duration (i.e. 24 μs) corresponding to the data stream 1.
Referring to fig. 7, as shown in fig. 9, the data stream transmission method provided in the embodiment of the present invention further includes S108.
And S108, the network equipment transmits the next data stream at the third moment.
The time interval between the third time and the second time is N preset transmission periods, and N is more than or equal to 1.
In connection with the above description of the embodiments, it should be understood that a transmission period of one data stream is used to characterize transmission of the data stream once every predetermined time period, where the predetermined transmission period is one of M transmission periods corresponding to the next data stream, and the network device may determine to transmit the next data stream in each of the M transmission periods.
It will be appreciated that the predetermined period of time is a length of time characterized by a transmission period of the data stream, i.e. the data stream is transmitted once per interval of the length of time. After the network device transmits the next data stream at the second time, the network device may determine to transmit the next data stream once every interval for a time period characterized by a transmission period of the next data stream. Specifically, when the second time is a certain time in the first transmission period (the first transmission period is one of the M transmission periods), the network device may determine that the third time is a certain time in one transmission period other than the first transmission period in the M transmission periods, that is, a time interval between the third time and the second time is N preset transmission periods, which may also be understood as N transmission periods of the next data stream.
Illustratively, in connection with the example of fig. 8 above, when the network device determines to transmit data stream 3 at time t2 in transmission period 1, the network device determines to transmit data stream 3 at time t4 in transmission period 2 (and at time t7 in transmission period 3). The time interval between the time t2 and the time t4 is a time length (i.e. 100 μs) characterized by 1 preset transmission period (in particular, the transmission period of the data stream 3), and the time interval between the time t2 and the time t7 is a time length (i.e. 200 μs) characterized by 2 preset transmission periods (i.e. the transmission period of the data stream 3).
In an alternative implementation, the network device may further determine to transmit the current data stream at a fourth time. Specifically, the time interval between the fourth time and the first time may be at least one transmission period of the current data stream.
In one implementation manner of the embodiment of the present invention, the network device may determine that the time interval between the first time and the third time (hereinafter referred to as a target duration) satisfies the following formula:
wherein T' represents the target duration, N represents the number of preset transmission periods of the interval between the third time and the second time, T represents the transmission period of the next data stream, 
Indicating the preset time period.
It should be understood that, since the second time and the first time belong to the same preset transmission period, the number of preset transmission periods between the third time and the second time may be also understood as the number of preset transmission periods between the third time and the first time, specifically, the number of N preset transmission periods in S108.
In the embodiment of the present invention, for the same data stream (for example, the next data stream), the time interval between two transmission moments (for example, the second moment and the third moment) corresponding to the next data stream is N transmission periods of the next data stream. For different data streams (for example, the next data stream and the current data stream), a time interval between a transmission time (for example, a second time or a third time) corresponding to the next data stream and a transmission time (for example, a first time) corresponding to the current data stream is the preset duration, or a sum of transmission periods of the N next data streams and the preset duration.
For example, in conjunction with the example in fig. 8, assuming that the data stream 2 is the current data stream, the data stream 3 is the next data stream, t1 is the first time, t2 is the second time, and t4 is the third time, the network device determines n=1, and the target duration is 112 μs.
In the embodiment of the present invention, the network device may further divide each of the plurality of data streams into at least one data packet (or data frame).
Alternatively, the size of one packet may be the maximum transmission unit (maximum transmission unit, MTU). Specifically, the network device may determine a ratio of a data size of a certain data flow (for example, the first data flow) to the MTU as a number of data packets included in the first data flow.
It should be noted that the network device may determine the number of data packets included in one data stream in a round-up manner. Specifically, if the data size of the first data stream is smaller than the MTU, the network device determines that the first data stream includes 1 data packet.
In an implementation manner of the embodiment of the present invention, the network device may further implement the adding process and the sending process of the at least two data flows based on a form of a data packet. Specifically, the network device may add at least one data packet included in each of the at least two data flows to the target queue, and transmit the at least one data packet included in each data flow based on the target queue.
The explanation of the network device adding the at least one packet included in each data stream to the target queue is the same as or similar to the description of the network device adding each data stream to the target queue. And, the explanation of the network device transmitting the at least one data packet included in each data stream based on the target queue is the same as or similar to the above description of the network device transmitting each data stream based on the target queue. And will not be described in detail herein.
In the embodiment of the present invention, the foregoing transmission (or transmission) process of at least two data flows may satisfy at least one of the following 5 constraints:
constraint 1: for a certain one of the at least two data streams (e.g. a first data stream), the end transmission time on any one of the first transmission paths is after the start transmission time on that link.
Constraint 2: if the transmission sequence of the second data stream is after the transmission sequence of the first data stream, for a link included in the preset cross-point, the transmission start time of the second data stream on the link is after the transmission end time (and the transmission start time) of the first data stream on the link.
Constraint 3: for a link included in the preset intersection, only one data stream can be transmitted on the link at a certain time (or within a certain time interval).
Specifically, at a time (or within the time interval), the network device allocates the resources of the link to a unique data flow.
Constraint 4: if a certain link (e.g., a first link) included in the first transmission path precedes a second link (a link other than the first link in the first transmission path), a start transmission time of the first data stream on the second link is after an end transmission time (and a start transmission time) of the first data stream on the first link.
Constraint 5: for one of the at least two data streams (e.g., the first data stream), the end-to-end transmission delay of the first data stream is less than or equal to the transmission period of the first data stream.
The end-to-end transmission delay of the first data stream may be a time difference between transmission of the first data stream from the source node to the destination node.
