Description

Data transmission control method and device, equipment and medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a data transmission control method, a data transmission control device, an electronic device, and a computer readable medium.

Background

In network function virtualization (Network Functions Virtualization, NFV) networks, an architecture employing an x86 server is adopted, which encapsulates different network functions such as routers, switches, firewalls, and load balancing into independent modular software, and by running different modular software on hardware devices, a diversified network function is realized on a single hardware device.

In the NFV network at present, as shown in fig. 1, there is no direct connection between the region a and the region B, and in order to open the connection between the region a and the region B, the connection is performed by bypassing the data transmission dedicated line between the region a to the region C and between the region C to the region B. The data enters through a data center Router (DataCenter Router, DR) of the region a, then flows into a Backbone Router (BR), then flows into the BR of the region B through a data transmission dedicated line between the region a to the region C and between the region C to the region B, and then flows out of the DR.

It is understood that customizable GateWay (GW) devices may be added to different domains in the NFV network, and may be controlled by a controller. Referring to fig. 1 again, the gw is usually mounted beside the DR, which does not affect data transmission.

Because a part of objects have higher requirements on network quality, in order to avoid network delay caused by detour of data transmission through other regions such as region C, in the related art, data designated by the objects are forwarded through other data transmission dedicated lines such as a third party dedicated line. As shown in fig. 2, since there is a direct third party dedicated line connection between the region a and the region B, data can enter through the DR of the region a, then flow into the GW of the region B through the third party dedicated line, and then flow out from the DR.

It can be understood that the data transmission between the region a and the region B is realized through the third party dedicated line, specifically, an instruction can be issued to the GW of the region a and the region B through the controller, a border gateway protocol (Border Gateway Protocol, BGP) neighbor is established, then a specific route is configured on the GW of the region B for the destination IP of the data to point to the DR, and then the GW of the region a learns the specific route through BGP and transmits the specific route to the corresponding DR.

However, since the third party dedicated line is leased by at least one operator of the two parties of the data transmission, the network quality is often uncontrollable, which may affect the normal transmission of the data. Therefore, how to detect the third party dedicated line to ensure the normal transmission of the data is a problem to be solved.

Various implementation details of the technical solutions of the embodiments of the present application are set forth in detail below:

referring to fig. 7, fig. 7 is a flowchart illustrating a method for controlling data transmission, which may be performed by the streaming calculator 302, according to an embodiment of the present application. As shown in fig. 7, the control method of data transmission at least includes S701 to S704, which are described in detail as follows:

S701, receiving a plurality of detection data packets sent by a detection party; the detection data packet is obtained by detecting network performance in the data transmission process of the data transmission special line by the detection guideline, and the data transmission special line is leased by an operator in at least one direction of the two data transmission parties.

In the embodiment of the application, a detecting party detects network performance aiming at the data transmission process of a data transmission special line to obtain a plurality of detection data packets, and sends the plurality of detection data packets to a streaming computing party; accordingly, the streaming calculator may receive a plurality of probe packets transmitted by the probe.

In the embodiment of the present application, the data transmission dedicated line is leased by at least one operator in both data transmission parties, that is, a third party dedicated line directly connected between the region a and the region B in the foregoing example; the network quality is often controllable, i.e. the dedicated line between the region a and the region C and the dedicated line between the region C and the region B in the foregoing example.

S702, calculating network performance index values in each transmission period contained in the data transmission process based on a plurality of detection data packets.

In this embodiment, the streaming computing side receives a plurality of detection data packets sent by the detecting side, and then may calculate the network performance index value in each transmission period included in the data transmission process based on the plurality of detection data packets.

It is understood that the data transmission process corresponds to a period of time, and the period of time can be subdivided into a plurality of transmission periods; for example, referring to fig. 8, the data transmission process includes 6 transmission periods, respectively T1', T2', T3', T4', T5', and T6', wherein the time periods corresponding to each transmission period may be the same or different, and the time periods corresponding to all the transmission periods are added to obtain the time period T corresponding to the data transmission process.

In the embodiment of the application, the network performance index is an index capable of reflecting the quality of the network, and includes, but is not limited to, a delay index, a packet loss rate index, a throughput index and the like. The time delay refers to a time interval from the first bit of the data packet entering the router to the last bit being output from the router, and can be divided into transmission time delay, propagation time delay, processing time delay, queuing time delay and the like; the better the network quality, the smaller the delay value, and conversely, the worse the network quality, the larger the delay value. Wherein the packet loss rate refers to the ratio of the number of lost data packets to the total number of transmitted data packets in the data transmission process; the better the network quality, the smaller the packet loss rate value is, and conversely, the worse the network quality, the larger the packet loss rate value is. Where throughput refers to the amount of successfully transmitted data (measured in bits, bytes, packets, etc.) per unit time; the better the network quality, the larger the throughput value is relatively, whereas the worse the network quality, the smaller the throughput value is relatively.

S703, detecting the data transmission condition of the data transmission special line based on the relation between the network performance index value in each transmission period and the preset threshold value.

In the embodiment of the present application, the streaming computing side calculates the network performance index value in each transmission period included in the data transmission process based on the plurality of detection data packets, and then can detect the data transmission condition of the data transmission dedicated line based on the relationship between the network performance index value in each transmission period and the preset threshold value.

In this embodiment of the present application, the relationship between the network performance index value and the preset threshold value in each transmission period refers to that each transmission period corresponds to a network performance index value, and the network performance index value corresponding to each transmission period has a relationship between the magnitude of the network performance index value and the preset threshold value.

In the embodiment of the application, the preset threshold corresponds to the network performance index; the preset threshold is a preset threshold corresponding to the time delay index if the network performance index is the time delay index, the preset threshold is a preset threshold corresponding to the packet loss rate index if the network performance index is the packet loss rate index, and the preset threshold is a preset threshold corresponding to the throughput index if the network performance index is the throughput index. In practical applications, the preset threshold is flexibly set by the relevant workers based on experiments or experience.

And S704, if the data transmission condition represents that the data transmission has a fault, fault information is sent to the control party, the fault information is used for indicating the control party to determine the fault type, and the data transmission special line is adjusted to be matched with the fault type.

In the embodiment of the application, the streaming computing party detects the data transmission condition of the data transmission special line based on the relation between the network performance index value in each transmission period and the preset threshold value, and then can determine the subsequent processing process according to the data transmission condition.

In one embodiment of the present application, if the data transmission condition indicates that there is a failure in the data transmission, the streaming calculator may send failure information to the controller, so that the controller may determine a failure type of the data transmission failure on the data transmission dedicated line based on the failure information, and perform adjustment matching the failure type on the data transmission dedicated line.

In one embodiment of the present application, if the data transmission condition indicates that there is a fault in the data transmission, the streaming computing party may send fault information to the alerting party, so that the alerting party may perform alert processing in a specified alert manner based on the fault information.

In one embodiment of the present application, if the data transmission conditions indicate that there is no failure in the data transmission, the streaming calculator may not be processing.

In the embodiment of the application, a streaming computing party performs computation based on a plurality of detection data packets sent by a detection party, and detects to obtain the data transmission condition of a data transmission special line in the data transmission process; thus, the detection of the data transmission special line is realized. The flow computing party computes the network performance index value in each transmission period contained in the data transmission process based on a plurality of detection data packets, and detects the obtained data transmission condition based on the relation between the network performance index value in each transmission period and a preset threshold value; therefore, a plurality of periods are used as detection references, and the accuracy of detecting the special data transmission line is greatly improved.

In one embodiment of the present application, another method of controlling data transmission is provided, which may be performed by the streaming calculator 302. As shown in fig. 9, the control method of data transmission may include S901 to S903, S701, S703 to S704.

S901 to S903 are described in detail as follows:

It should be noted that, here, only a small amount of probe packets are included in the transmission period in the illustrated example, and in practical application, the transmission period can be flexibly adjusted according to a specific application scenario.

Wherein the structured data refers to Person type data, and the certain coding specification refers to the specification of the XML document. Generally, the common serialization methods include binary serialization, XML serialization, and JS object profile (JavaScript ObjectNotation, JSON) serialization.

For example, in connection with the foregoing example, the probe packet 1-2 in the transmission period T1 'may be subjected to the deserialization processing to obtain the probe packet 1' -2 'having the specified structure in the transmission period T1'. The same applies to the other transmission periods T2', T3', T4', T5', T6 '.

It should be noted that, only one probe packet shown in the example includes a small amount of probe data, and in practical application, the probe packet may be flexibly adjusted according to a specific application scenario. The same applies to the other transmission periods T2', T3', T4', T5', T6 '.

For example, with the foregoing example taken in mind, the network performance index value within the transmission period T1 'may be calculated based on a plurality of probe data n11', n12', n13', n14', n21', n22', n23', n24', n25', n26 'having a specified structuring within the transmission period T1'. The same applies to the other transmission periods T2', T3', T4', T5', T6 '.

That is, in an alternative embodiment, the flow calculator calculates the network performance index values corresponding to the plurality of probe data in each transmission period, and then calculates the network performance index values in each transmission period based on the network performance index values corresponding to the plurality of probe data in each transmission period.

Optionally, the network performance index values in each transmission period are calculated based on the network performance index values corresponding to the plurality of detection data in each transmission period, and the network performance index values corresponding to the plurality of detection data may be summed and averaged for each transmission period to obtain the network performance index value in each transmission period.

For example, in connection with the foregoing example, for the transmission period T1', the network performance index values corresponding to the plurality of probe data n11', n12', n13', n14', n21', n22', n23', n24', n25', n26 'are summed and averaged to obtain the network performance index value in the transmission period T1'. The same applies to the other transmission periods T2', T3', T4', T5', T6 '. It should be noted that, the operation is only one illustrated example, but may be other operations, and in practical application, the operation may be flexibly adjusted according to a specific application scenario.

In the embodiment of the application, the streaming computing party performs deserialization processing on the detection data packets in each transmission period, and then performs splitting processing on the detection data packets with appointed structures in each transmission period; therefore, the detection data with the appointed structure in each transmission period can be accurately obtained, and the accuracy of the network performance index value in each transmission period, which is calculated based on the detection data with the appointed structure in each transmission period, is improved.

In one embodiment of the present application, another method of controlling data transmission is provided, which may be performed by the streaming calculator 302. As shown in fig. 11, the control method of data transmission may include S1101 to S1102, S701 to S702, S704.

S1101 to S1103 are described in detail as follows:

s1101, obtaining the type of the network performance index, and determining a target strategy based on the type of the network performance index.

In the embodiment of the application, different types of network performance indexes correspond to different strategies; the policy is used for indicating how to acquire the network performance index value in the transmission period, and the target policy is a policy corresponding to the type of the network performance index.

Referring to table 1 below, an exemplary mapping table of type and policy of preset network performance indexes is shown, wherein the mapping table of type and policy of preset network performance indexes is preset with a plurality of types of network performance indexes and policies corresponding to the plurality of types of network performance indexes respectively.

Type of network performance index	Strategy
		Time delay	Successive 3 transmission periods
Packet loss rate	Successive 3 transmission periods
		Throughput of	Discontinuous 2 transmission periods
……	……

TABLE 1

In one embodiment of the present application, the process of determining the target policy based on the type of the network performance index in S1101 may include at least the following steps:

based on a preset network performance index type and a strategy mapping relation table, determining a strategy corresponding to the network performance index type, and taking the determined strategy as a target strategy.

That is, in an alternative embodiment, the streaming calculator may search the policy corresponding to the type of the network performance index from the preset mapping relationship table of the type of the network performance index and the policy, where the searched policy is the target policy.

S1102, acquiring network performance index values in a specified number of transmission periods based on the target strategy.

In the embodiment of the application, the streaming computing party acquires the type of the network performance index, determines the target strategy based on the type of the network performance index, and then acquires the network performance index value in a specified number of transmission periods based on the target strategy.

For example, in the foregoing example, the network performance index values in the transmission periods T1', T2', T3', T4', T5', T6' are calculated, and if the network performance index is a delay index, the target policy is 3 consecutive transmission periods based on the foregoing table 1. Therefore, the network performance index values in the 3 continuous transmission periods T1', T2', T3 'need to be acquired, the network performance index values in the 3 continuous transmission periods T2', T3', T4' need to be acquired, the network performance index values in the 3 continuous transmission periods T3', T4', T5 'need to be acquired, and the network performance index values in the 3 continuous transmission periods T4', T5', T6' need to be acquired.

And S1103, if the network performance index value in the designated number of transmission periods reaches a preset threshold value, obtaining a transmission condition for representing that the data transmission has faults.

In the embodiment of the application, the streaming calculator acquires the network performance index value in the designated number of transmission periods based on the target policy, and then obtains the transmission condition for representing whether the data transmission has a fault or not based on the magnitude relation between the network performance index value in the designated number of transmission periods and the preset threshold.

And if the network performance index value in the designated number of transmission periods reaches a preset threshold value, obtaining a transmission condition for representing that the data transmission has faults.

It will be appreciated that the network performance index value over a specified number of transmission cycles may be compared to a preset threshold value each time the network performance index value over the specified number of transmission cycles is obtained based on the target policy. For example, in the foregoing example, the network performance index values in 3 consecutive transmission periods of T1', T2', and T3 'are obtained and compared with the preset threshold, respectively, and if the network performance index values in 3 consecutive transmission periods of T1', T2', and T3' reach the preset threshold, the network performance index values in the specified number of transmission periods can be obtained without obtaining the network performance index values in 3 consecutive transmission periods of T2', T3', and T4', and the network performance index values in 3 consecutive transmission periods of T4', T5', and T6', respectively, which can reduce the resource consumption of the streaming computing party to a certain extent.

And if the network performance index value in any transmission period in the appointed number of transmission periods does not reach the preset threshold value, obtaining the transmission condition for representing that the data transmission has no fault.

It can be understood that the network performance index values in all the designated number of transmission periods need to be obtained based on the target policy, so that when the network performance index value in any transmission period in the designated number of transmission periods does not reach the preset threshold, a transmission condition for representing that no fault exists in data transmission can be obtained. For example, in the foregoing example, the transmission situation for characterizing that the data transmission has not failed cannot be directly obtained because the network performance index value in any one of the 3 acquired transmission periods T1', T2', T3 'does not reach the preset threshold, which is further required to be sequentially based on the network performance index values in the 3 acquired transmission periods T2', T3', T4', the network performance index values in the 3 continuous transmission periods T3', T4', T5 'and the network performance index values in the 3 continuous transmission periods T4', T5', T6' are compared to finally obtain the transmission condition for representing that the data transmission has no fault, so that the accuracy of the detected transmission condition of the data transmission special line can be improved to a certain extent.

It should be noted that, for the detailed description of S701 to S702 and S704 shown in fig. 11, please refer to S701 to S702 and S704 shown in fig. 7, and the detailed description is omitted here.

According to the method, a streaming computing party determines a target strategy based on the type of the acquired network performance index, acquires network performance index values in a specified number of transmission periods based on the target strategy, and then detects whether the acquired network performance index values in the specified number of transmission periods reach a preset threshold value or not, so that the data transmission condition of a data transmission dedicated line is detected; the data transmission conditions of the data transmission special lines detected according to the network performance indexes of different types are different, the flexibility is higher, and the method is applicable to wider application scenes.

S1401 to S1402 are described in detail as follows:

s1401, transmitting a plurality of detection data packets to a message queue for buffering; the message queues are used for respectively buffering a plurality of detection data packets obtained by network performance detection of each detection party aiming at the data transmission process of the data transmission special line.

It should be noted that, the embodiments shown in fig. 13 to 14 are explained from the perspective of the detecting party, and the following details of implementation of the technical solutions of the embodiments of the present application are explained in detail from the perspective of the controlling party with reference to fig. 15 to 16:

Referring to fig. 15, fig. 15 is a flowchart illustrating a control method of data transmission, which may be performed by the controller 303 according to an embodiment of the present application. As shown in fig. 15, the control method of data transmission at least includes S1501 to S1503, which are described in detail as follows:

s1501, receiving fault information sent by a stream computing side; the fault information is sent when the stream computing party detects the data transmission condition of the data transmission special line and represents the fault of the data transmission based on a plurality of detection data packets sent by the received detection party, network performance index values in all transmission periods contained in the data transmission process and the relation between the network performance index values in all the transmission periods and a preset threshold value.

In the embodiment of the application, a streaming computing party calculates network performance index values in each transmission period contained in a data transmission process based on a plurality of received detection data packets sent by a detection party, detects the data transmission condition of a data transmission dedicated line based on the relation between the network performance index values in each transmission period and a preset threshold value, and sends fault information to a control party when the transmission condition represents that data transmission has faults; accordingly, the controller may receive the failure information sent by the streaming calculator. Please refer to the foregoing embodiments for the processing procedure of the flow-type computing method, and the description thereof is omitted herein.

S1502, determining a fault type of the data transmission fault on the data transmission special line based on the fault information.

In the embodiment of the application, the control party receives the fault information sent by the stream computing party, and then can determine the fault type of the data transmission fault generated on the data transmission dedicated line based on the fault information.

The fault types in the embodiment of the present application are divided into two types; one of the types of faults is that the data transmission dedicated line has faults as a whole, which belongs to the consideration of the large granularity level of the data transmission dedicated line, and the type of faults can be obtained by a stream calculator based on a plurality of detected data packets detected by a network detector as described in the previous embodiment; the other is a failure type in which a data transmission dedicated line is partially failed, which is a consideration from a small granularity level of the data transmission tunnel, and it may be obtained by the stream calculator detecting a plurality of detected data packets based on the gateway device as described in the foregoing embodiment.

S1503, adjusting the data transmission special line to be matched with the fault type.

In the embodiment of the application, the controller determines the fault type of the data transmission fault generated on the data transmission special line based on the fault information, and then can adjust the data transmission special line in a matching manner with the fault type.

In one embodiment of the present application, if the fault type indicates that the data transmission dedicated line has a fault in its entirety, the data transmitted on the data transmission dedicated line is adjusted to be transmitted on other data transmission lines. That is, if the data transmission dedicated line has a fault, the data transmitted on the whole data transmission dedicated line needs to be adjusted to other data transmission lines for transmission, so that the normal transmission of the data is ensured.

For example, referring to fig. 2 again, the data transmitted on the third party dedicated line shown in fig. 2 may be adjusted to be transmitted on the data transmission dedicated line between the region a to the region C and the region C to the region B.

In one embodiment of the present application, if the fault type indicates that the data transmission dedicated line has a fault locally, the data transmitted on the data transmission tunnel with the fault included in the data transmission dedicated line is adjusted to the data transmitted on other data transmission tunnels included in the data transmission dedicated line. That is, if the data transmission dedicated line has a fault in a local part (i.e., the data transmission tunnel), the data transmitted on the data transmission tunnel with the fault needs to be adjusted to other data transmission tunnels contained in the data transmission dedicated line for transmission, so that normal transmission of the data is ensured.

For example, referring to fig. 6 again, assuming that the failed data transmission tunnel is k11, the data transmitted on the data transmission tunnel k11 may be adjusted to the data transmitted on the other data transmission tunnels k12, k13, k 14. The data transmitted on the data transmission tunnel k11 can be adjusted to any one or more of the other data transmission tunnels k12, k13, k 14. Alternatively, the data transmitted over the data transmission tunnel k11 may be equally tuned to the other data transmission tunnels k12, k13, k14, i.e. each of the other data transmission tunnels k12, k13, k14 carries about 33% of the data transmitted over the data transmission tunnel k 11.

In the embodiment of the application, the control party determines the fault type based on the fault information sent by the stream computing party, and adjusts the data transmission special line in a matching manner with the fault type; therefore, the control party is instructed to correspondingly adjust the data transmission special line through the sending of the fault information, the phenomenon that the normal transmission of the data is influenced due to uncontrollable network quality of the data transmission special line in the related art can be avoided, the normal transmission of the data is ensured, the success rate of the data transmission is greatly improved, and the method is suitable for application scenes with high requirements on the network quality.

In one embodiment of the present application, another control method of data transmission is provided, which may be performed by the controller 303. As shown in fig. 16, the control method of data transmission may include S1601 to S1604, S1501, S1503.

S1601 to S1604 are described in detail as follows:

s1601, a transmission line identifier of the failure is obtained from the failure information.

In the embodiment of the application, the fault information comprises a transmission line identifier with a fault, wherein the transmission line identifier refers to a unique identifier for representing a transmission line; therefore, the controller in the embodiment of the application can obtain the failed transmission line identification from the failure information.

S1602, determining an identification corresponding to the transmission line identification based on a preset private line identification and tunnel identification table.

In this embodiment of the present application, a preset dedicated line identifier and a tunnel identifier table are preset, refer to table 2 below, which is an example of a preset dedicated line identifier and a tunnel identifier table, where the preset dedicated line identifier and the tunnel identifier table are preset with identifiers of data transmission dedicated lines, and identifiers of data transmission tunnels respectively corresponding to the identifiers of the data transmission dedicated lines.

TABLE 2

It can be understood that the preset special line identifier and the tunnel identifier table in the illustrated example are in a table form, and can be split into two table forms, so that in practical application, the preset special line identifier and the tunnel identifier table can be flexibly adjusted according to specific application scenes.

In the embodiment of the application, the controller can search the identifier corresponding to the transmission line identifier from the preset special line identifier and tunnel identifier table, and then can obtain the fault type for representing that the whole or part of the data transmission special line has faults based on the searched identifier.

S1603, if the determined identification is matched with the special line identification, obtaining a fault type for representing that the whole data transmission special line has faults.

In the embodiment of the application, if the determined identifier is matched with the dedicated line identifier, the fault type used for representing the fault of the whole data transmission dedicated line can be obtained.

S1604, if the determined identification is matched with the tunnel identification, obtaining a fault type used for representing that the data transmission special line has a fault locally.

In the embodiment of the application, if the determined identifier is matched with the tunnel identifier, the fault type used for representing that the data transmission special line has a fault locally can be obtained.

Note that, in the detailed description of S1501 and S1503 shown in fig. 16, reference is made to S1501 and S1503 shown in fig. 15, and the detailed description is omitted here.
