Description

TECHNICAL FIELD The present invention relates to network communication technologies, and in particular, to a dynamic control transmission method and apparatus based on network traffic flow. BACKGROUND At present, with the development of network technologies, users have higher and higher requirements for the service data information they receive, similar to video calls or online games, and different services have different requirements for network transmission, that is, services. Shield

The requirements for (QoS) are also different. In order to solve the different requirements of different users for service flows, the general technical solution is to divide the service flow into thousands of different priorities according to the similarity of QoS requirements, and identify and classify the border routers and intermediate routers respectively. Operations such as tagging and traffic management to manage and allocate network resources for integrated traffic flows in the network at a statistical level, but this model cannot effectively manage and accurately control a single traffic flow, resulting in bandwidth between multiple traffic flows. Unbalanced distribution and instability of traffic flow bandwidth control.

For the above reasons, the overall minimum allocation scheme based on each service flow is proposed from the three dimensions of setting the priority, the preemption degree and the minimum maintenance bandwidth of the traffic flow value control. In actual traffic transmission, most of the traffic flows (about 80 ~ 90%) are small from the network traffic monitoring analysis, and only a small part of the traffic (about 10 ~ 20%) is large, but this part The traffic flow occupies most of the network traffic (about 80% or more). This part of the traffic that accounts for more network traffic is a key business flow, which is very important for the transmission of key business flows. Then there is a prominent problem in the lowest allocation scheme. The data transmission priority of the network traffic flow is generally determined, but the traffic of one of the service flows also suddenly increases due to the user's request. The traffic of the service flow is not guaranteed due to the transmission of the same priority, because the transmission of the minimum bandwidth of the overall transmission is guaranteed.

For this reason, based on the minimum bandwidth transmission, there is a need for a method of automatically controlling the transmission when the traffic of the transmission of certain traffic flows is increased. SUMMARY OF THE INVENTION In view of this, the technical solutions of the embodiments of the present invention are as follows:

The invention provides a dynamic control transmission method based on network service flow, which comprises:

(1) identifying a data type transmitted on a network device port, where the data type includes a service flow based service flow and a non-service transmission based non-service flow, wherein the service flow is divided into a single service flow and a multi-service flow; (2) setting a traffic transmission threshold of the network device port according to the data type, and setting a transmission priority and a preemption degree of each service flow, where the port of the multi-service flow or the single service traffic within the determined time period is higher than the default. The port at the traffic threshold is set to the cascading port by default. The cascading port and the non-cascading port are connected according to the topology relationship between the private protocol and the network device between the control cascade ports.

(4) dynamically controlling the traffic of the original cascade port and the non-cascading port according to the change of the ratio of the actual traffic flow of the service flow to the service flow priority of the non-cascading port.

When the data type of the non-cascading port transmission is a multi-service flow, the traffic value of each service flow received in the multi-service flow in the predetermined time period is counted, and is preset with the corresponding respective service flows. The output priority level is used as the ratio operation, and the service flow with the highest ratio value is transmitted with the highest priority;

And, when the traffic value received by the service flow with the lowest output priority level in the multi-service flow is greater than its preset threshold, and the ratio of the ratio of the output priority level value to the preset output priority level is the lowest, the The traffic flow is suspended for a preset period of time.

When the data type transmitted by the non-cascading port is a single service flow, the traffic value of the service received by the port in the predetermined time period is counted.

When the traffic value of the port receiving service in the predetermined time period is greater than the traffic threshold of the port, the port is used as a cascade port, and is connected to other non-cascading ports of the corresponding type according to the single service flow type.

The dynamic control transmission of the service flow of the original cascading port and the non-cascading port further includes: adjusting the transmission traffic of the network port, where the traffic transmission threshold of the cascading port is smaller than the traffic transmission threshold of the non-cascading port The traffic transmission threshold of the cascading port is adjusted, where the traffic transmission threshold of the cascading port is greater than that of all the cascading ports when the data type of the non-cascading port is multi-service flow The maximum actual transmission traffic of the service flow with the highest ratio value.

The embodiments of the present invention are described in the following with reference to the accompanying drawings, and the embodiments of the invention are intended to illustrate and explain the invention.

The present invention sets traffic for transmission of each service flow by first identifying the type of each service flow in the network transmission. The threshold value ensures that each service flow can transmit substantially normal traffic in the network transmission; and at the same time, for each change of the service flow, the transmission priority based on each service flow is compared with the change of the actual transmission traffic to determine that some Or a large traffic change in some service flows is a method of dynamically controlling transmission. This method can ensure the normal transmission of service flows, and can ensure the transmission of some large-traffic traffic in actual applications, thereby ensuring specific service flow requirements. The amount of service shield.

The basic implementation of the present invention is shown in Figure 1, and the specific steps are as follows:

A dynamic control method based on network service flow provided by an embodiment of the present invention includes:

Step 101: Identify a data type transmitted at a network device port, where the data type includes a service flow based service flow and a non-service transmission based non-service flow, where the service flow is classified according to the type of data type included therein. Business flow and multi-service flow;

The method of identification here collects detailed data information of a stream including source, destination address, port number, protocol, service type, start and end time, packet and number of bytes, etc., and through service flow determination, service flow classification and identification, Traffic flow sampling, traffic flow monitoring, and traffic flow feature analysis and traffic modeling techniques are identified. For service flows and non-service flows, the protocol feature words in the data packets are mainly identified, and the non-service flows mainly refer to A private protocol and a public protocol for controlling data stream transmission, such as IGMP, etc., which controls Internet group management, and a private protocol controls a control protocol for data redundancy transmission of a network node, such as a PRP parallel redundancy protocol.

For single-service and multi-service, the main purpose is to further analyze the data received by the network device port, which involves the determination of service flow and service flow classification. The decision of the service flow is generally identified by a series of bursts of packet rows of the same source and destination (determining the interval between two packets as the same packet), and all packets of the same TCP connection. For the same service flow setting method (that is, according to the TCP protocol itself, such as SYN and FIN for service flow division). For service flow classification, it is generally based on service flow attributes, such as: directionality of data transmission and end judgment method as the basis of service flow classification, but it is necessary to further understand the overall service flow characteristics of network traffic, and must also analyze other statistical characteristics of service flow. For example: size of the traffic (byte size and packet size), growth rate, traffic duration, and so on.

For example, through the analysis of network data. In terms of traffic flow size, many actual network traffic monitoring and analysis found that most of the traffic (about 80 ~ 90%) is small, and only a small part of the traffic (about 10 ~ 20%) is large, but this part of the business The flow occupies most of the network traffic (about 80% or more). This part of the traffic that accounts for more network traffic is a key service flow, and priority traffic is required for key service flows. For key business flows, the traffic value calculation method is used, or the service flow rate and the service flow duration are judged. For multi-service flows, the ports of the network device mainly perform multiple types of service flows for transmission. The type of service flow here mainly refers to the type of service such as mail or multimedia.

Step 102: Set a corresponding traffic transmission threshold of the relevant network device port according to the data type, and set a priority and a preemption degree of each service flow, where the port of the multiple service flow or the single service traffic within the determined time period is higher than the default. By default, the port is configured as a cascading port. The cascading port and the non-cascading port are connected according to the topology relationship between the private protocol and the network device between the control cascading ports.

The network device is not a separate device for data transmission, and the network device is connected into a chain or ring network for data transmission. Regardless of the chain network or the ring network, there is a redundancy problem involving the transmission of data by the network device, that is, the reliability problem. The reliability here is generally solved by the network equipment manufacturer's own proprietary protocol, such as PRP redundancy protocol (parallel redundancy protocol) and HSR protocol (high reliability redundant ring network). The network device port responsible for the network port logic switch in the chain network or ring network formed by the connection of multiple network devices is the main port connecting other network devices, and is also the main port for multi-service stream transmission, which is called a cascade port. That is to say, the connection between the cascaded ports forms the transmission of the bones, but the single-service flow with a large amount of data can also be a cascade port, and the cascade port is connected to the non-cascading port instead of the cascade port and the terminal device. The connection gets the business flow (including single business flow and / or multi-service flow).

103. Detecting traffic of a service flow of a non-cascading port in a predetermined time period, when detecting that the actual traffic flow of the service flow is lower than a traffic flow threshold set by the non-cascading port, each service The flow is transmitted according to the setting of the transmission priority and the preemption; when it is detected that the actual transmission traffic of the service flow exceeds the traffic flow threshold set by the non-cascading port, the preemption of the original fixed setting of the service flow is changed. Degree, and reset the ratio of the priority of the service flow to the actual transmission traffic;

The predetermined time period here can be set according to the actual situation, for example: 30 seconds or 10 minutes, but this set time should be 'j, more than the actually detected time exceeding the flow threshold. Here, the method of traffic monitoring may be based on the port number of the Internet number assignment management authority, or may be based on the keyword characteristics of the service flow.

When the non-cascading port detects the actual transmission traffic of a certain service flow within a preset time, when the actual transmission traffic is smaller than the traffic flow threshold, each service flow is transmitted according to a fixed setting of the transmission priority and the preemption degree; When the actual traffic flow is not less than the traffic flow threshold, the preemption should be reset according to the ratio of the priority of the traffic flow to the actual traffic flow.

The preemption here indicates the ratio of the actual bandwidth that all traffic of this type can obtain to the input bandwidth of all traffic flows in the type in the allocation process, with the remaining bandwidth of the network allowed. The value of the preemption is 0 < and < 1 .

104. Perform dynamic control transmission on the service flows of the original cascade port and the non-cascading port according to the change of the ratio of the actual traffic flow of the service flow to the service flow priority of the non-cascading port.

Since the existing technical solution proposes an overall minimum allocation scheme based on each service flow from three dimension directions of setting priority of the network data traffic value, preemption degree, and minimum maintenance bandwidth of the service flow, the transmission of the service flow is based on the advance Set the priority to set the traffic size used by the service flow, and ensure the minimum maintenance bandwidth of each service flow, that is, the traffic of the service flow in the transmission process is basically determined, and the traffic demand of the entire service flow is large. At this time, the traffic of the key service flow cannot be guaranteed. In this solution, the ratio of the actual traffic flow of the service flow to the service flow priority of the non-cascading port is used to reset the preemption, and the preemption here is dynamic. Data, because The actual transmission traffic for the traffic flow is dynamically transmitted, and the optimal transmission of the high priority traffic with high priority is also ensured.

Based on the basic embodiment, further, FIG. 2 is a flowchart of a dynamic control method based on multiple services in a network service flow according to an embodiment of the present invention.

As shown in Figure 2, the specific steps are:

201: Calculate a traffic value of each service flow received in the multiple service flow in a predetermined time period, and perform a ratio operation with a preset output priority level of each of the corresponding service flows;

202: The service flow with the highest ratio value is transmitted with the highest priority;

203: When, when the traffic value received by the service flow with the lowest output priority level in the multi-service flow is greater than its preset threshold, and the ratio of the ratio of the output priority level to the preset output priority level is the lowest, Pausing the service flow as a pause transmission within a preset time period

In this step, for the multi-service flow transmitted in the non-cascading end, for example, three kinds of service streams of video, mail, and sample are transmitted, and the transmission priorities are 1, 2, and 3 respectively, and the preemption degree is also 0.4, respectively. 0.4, 0.3, after the predetermined time detection, the mail and service traffic value exceeds the set threshold, and the video is lower than the threshold. At this time, the actual detected traffic is 2M, 20M, 15M, then the actual transmission according to the service flow The ratio of traffic to priority is 2, 10, and 5 respectively. At this time, the mail service flow is a large service flow, that is, a key service flow, and priority transmission should be ensured. In addition, if the actual detection traffic is 2M, 20M, 3M respectively. Then, according to the actual transmission traffic and the priority ratio of the service flow are 2, 10 and 1, respectively, at this time, the service flow is used as the original transmission priority is the lowest, and the actual transmission traffic and the priority ratio of the service flow are the lowest. , then suspend the traffic flow, the actual time is a lot, because the normal critical service flow is also bursty transmission in a short period of time, if the actual traffic In the case of a pause in transmission, the priority of the setting is unreasonable. Here you need to #> reset according to the actual situation. Based on the basic embodiment, further, as shown in FIG. 3, it is a working flowchart of a dynamic control method based on a single service in a network service flow according to an embodiment of the present invention.

When the data type of the non-cascading port is a single service flow, the traffic value of the service received by the port in the predetermined time period is counted, and when the traffic value of the port receiving service in the predetermined time period is greater than the traffic threshold of the port The port is used as a cascade port, and is connected to other non-cascading ports of the corresponding type according to the single service flow type.

As shown in Figure 3, this step is as follows: 301: Counting the traffic value of the service received by the port in the predetermined time period;

302: When the traffic value of the port receiving service in the predetermined time period is greater than the traffic threshold of the port, the port is used as a cascading port;

303: Simultaneously connect with other non-cascading ports of the corresponding type according to the single service flow type.

The service flow transmitted by the non-cascading port may be a single service flow. In this case, different and multiple service flows are used. This solution will be converted to a cascade port to continue to transmit this type of service flow, which can reduce the network. Difficult to set the port

Further, as shown in FIG. 4, the working flow chart of the cascading port adjustment based on the network service flow is provided in the embodiment of the present invention, and the data flow of the original cascading port and the non-cascading port is further included in the transmission control. Adjusting the transmission traffic of the network port, and adjusting the traffic transmission threshold of the cascade port when the traffic transmission threshold of the expansion port is smaller than the traffic transmission threshold of the non-cascading port, where the non-cascading port is When the data type of the transmission is multi-service flow, the traffic transmission threshold of the cascade port should be greater than the maximum actual transmission traffic of all service flows that have the highest ratio value in the cascade port.

This step is as follows:

401: Adjust transmission traffic of the network port;

402: Adjust a traffic transmission threshold of the cascading port when a traffic transmission threshold of the cascading port is smaller than a traffic transmission threshold of the cascading port;

403: wherein, when the data type of the non-cascading port is a multi-service flow, the traffic transmission threshold of the cascade port is greater than the maximum actual traffic of all service flows that have the highest ratio value in the cascade port. .

In general, the traffic transmission threshold of the cascade port is larger than the non-cascading port traffic threshold, but if the private protocol (such as the redundancy protocol) is based on the redundancy requirement of the link, the non-cascading port is set to cascade. Port, at this time, the threshold of the non-cascading port is smaller than the threshold of the cascade port, which is not allowed in actual network transmission. For this reason, the threshold setting of the new cascade port should be greater than the actual transmission traffic and priority. The sum of the thresholds of the service flow with the highest ratio, the hardware device of the network device port cannot transmit traffic without restriction. Therefore, the traffic transmitted by the network port needs to be restricted to ensure the secure transmission of the data stream. In general, the traffic of large traffic in the network is sporadic. The smoothness of data transmission should be determined in the network transmission. To this end, ensure that the threshold setting of the cascade port should be greater than the actual transmission traffic and priority. The sum of the thresholds of the service flow with the highest ratio, that is, to ensure that the cascade port can transmit the large amount of data that occurs in a service flow. Of course, if there is another big data stream at the same time, you need to compare the priority transmission of the service flow on the cascade port to ensure that the network port will not be paralyzed due to data congestion.

FIG. 5 is a structural block diagram of a dynamic control transmission apparatus based on a network service flow according to an embodiment of the present invention. The apparatus shown in FIG. 5 corresponds to the steps shown in FIG. 1, and the related description is not described again. The apparatus includes:

a service flow setting module 501, configured to identify a data type transmitted at a network device port, where the data type includes a service flow based service flow and a non-service flow based non-service flow, wherein the service flow is classified into a single service flow and a multi-service flow according to the type of the data type included therein;

The service flow threshold setting module 502 is configured to set a traffic transmission threshold of the relevant network device port according to the data type, and set a transmission priority and a preemption degree of each service flow, where the port of the multiple service flow or the determined time period When the single-service traffic is higher than the default traffic threshold, the default setting is the cascading port. The cascading port and the non-cascading port are connected according to the topology relationship between the private protocol and the network device between the cascading ports.

The service flow static setting module 503 is configured to detect traffic of the service flow of the non-cascading port within a predetermined time period, and when detecting that the actual traffic flow of the service flow is lower than the service set by the non-cascading port When the traffic flow threshold is used, each service flow is transmitted according to the setting of the transmission priority and the preemption degree; when it is detected that the actual transmission traffic of the service flow exceeds the traffic flow threshold set by the non-cascading port, the service flow is changed. The traffic flow is originally fixedly set to the preemption degree, and the preemption degree is reset according to the ratio of the priority of the service flow to the actual transmission traffic;

The service flow dynamic setting module 504 is configured to dynamically control the service flow of the original cascade port and the non-cascading port according to the change of the ratio of the actual traffic flow of the service flow to the service flow priority of the non-cascading port. .

Further, FIG. 6 is a schematic structural diagram of a network traffic flow-based dynamic control apparatus according to an embodiment of the present invention, and the apparatus shown in FIG. 6 corresponds to the steps shown in FIG. 2, and the related description is not repeated herein. The service flow dynamic setting module provided by the embodiment of the invention further includes: a service flow ratio value highest module, configured to: when the data type transmitted by the non-cascading port is a multi-service flow, receive the multi-service flow in the predetermined time period for receiving The traffic value of each service flow to be compared with the output priority level of each corresponding service flow preset, and the service flow with the highest ratio value is transmitted with the highest priority; the service flow ratio value is the lowest module, When the traffic value received by the service flow with the lowest output priority level in the multi-service flow is greater than its preset threshold, and the ratio of the ratio of the output priority level to the preset output priority level is the lowest, the service is The stream is paused for transmission within a preset time period.

Further, the service flow dynamic setting module further includes: when the data type transmitted by the non-cascading port is a single service flow, counting the traffic value of the service received by the port in the predetermined time period, when the predetermined time period is When the traffic value of the port receiving service is greater than the traffic threshold of the port, the port is used as a cascade port, and is connected to other non-cascading ports of the corresponding type according to the single service flow type.

The service flow transmitted by the non-cascading port may be a single service flow. In this case, different and multiple service flows are used. This solution will be converted to a cascade port to continue to transmit this type of service flow, which can reduce the network. The difficulty of setting the port.

Then, the service flow dynamic setting module further includes: adjusting the transmission traffic of the network port, and adjusting the cascading when the traffic transmission threshold of the cascading port is smaller than the traffic transmission threshold of the non-cascading port The traffic transmission threshold of the port, wherein when the data type of the non-cascading port is a multi-service flow, the traffic transmission threshold of the cascade port is greater than the service flow with the highest ratio value among the cascade ports. Maximum actual transmission traffic.

In general, the traffic transmission threshold of the cascade port is larger than the non-cascading port traffic threshold, but if it is private A protocol (such as a redundancy protocol) sets a non-cascading port as a cascading port according to the redundancy requirement of the link. In this case, the threshold of the non-cascading port is smaller than the threshold of the cascading port, in actual network transmission. It is not allowed. For this reason, the threshold setting of the new cascade port should be greater than the sum of the thresholds of the service flow with the highest ratio of the actual transmission traffic and the priority.

The hardware device of the network device port cannot be used for unlimited traffic transmission. Therefore, it is necessary to limit the traffic transmitted by the network port to ensure the secure transmission of the data stream. In general, the traffic of large traffic in the network is sporadic. The smoothness of data transmission should be determined in the network transmission. To this end, ensure that the threshold setting of the cascade port should be greater than the actual transmission traffic and priority. The sum of the thresholds of the service flow with the highest ratio, that is, to ensure that the cascade port can transmit the large amount of data that occurs in a service flow. Of course, if there is another big data stream at the same time, you need to compare the priority transmission of the service flow on the cascade port to ensure that the network port will not be paralyzed due to data congestion.
