Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In a specific practical process, the applicant of the present application finds that, in a process of transmitting business data traffic related to a cross-data center network, a situation that a transaction amount is greatly increased in a short time due to some marketing activities, for example, sales promotion activities of sales platforms on various networks, is sometimes found, and a sudden large flow may occur in a cross-center private line. When the dedicated bandwidth cannot effectively carry the traffic, congestion occurs, even a large amount of packet loss occurs, resulting in transaction failure. In order to avoid the situation, the burst traffic must be shunted in time after the burst traffic is generated, that is, part of the burst traffic is introduced into other special lines with lower load, so that the stable operation of the production network is ensured.
For example, as shown in fig. 1, two data centers exist in fig. 1, which are a first data center and a second data center respectively, the first data center is connected to the second data center through a dedicated line 1 and a dedicated line 2, the dedicated line 1 is a dedicated line for processing a card-less service traffic, and the dedicated line 2 is a dedicated line for processing a banking service traffic, so that when the card-less service traffic suddenly increases, the load of the dedicated line 1 is too high, and congestion and packet loss are generated.
In the prior art, the flow of the card-free service is equally divided into two parts, 50% of the flow is reserved on a special line 1, and the other 50% of the flow is divided into two parts on a special line 2. For example, in fig. 1, the flow rate of the cardless service is 800M, the flow rate of the banking service is 400M, however, the flow rate that the private line 1 can bear is 600M, and the flow rate that the private line 2 can bear is 400M, if the method of the average flow is used, the load on the private line 2 becomes 800M, which exceeds the load on the private line 2, and causes congestion and packet loss, that is, the above technical problem cannot be solved in the prior art.
Based on the above drawbacks of the prior art, the applicant of the present application has conceived a service flow control method, and when a burst flow occurs, a dedicated line matched with the burst flow is determined, and the burst flow is sent to a second data center, so as to achieve the purpose of shunting the burst flow.
After introducing the design concept of the embodiment of the present application, some simple descriptions are provided below for application scenarios to which the technical solution of the embodiment of the present application can be applied, and it should be noted that the application scenarios described below are only used for describing the embodiment of the present application and are not limited. In specific implementation, the technical scheme provided by the embodiment of the application can be flexibly applied according to actual needs.
To further illustrate the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the accompanying drawings and the detailed description. Although the embodiments of the present application provide the method operation steps as shown in the following embodiments or figures, more or less operation steps may be included in the method based on the conventional or non-inventive labor. In steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application.
An embodiment of the present application provides a method for controlling a traffic flow, specifically as shown in fig. 2, including:
step S201, a first data center obtains a total traffic of service data that needs to be currently transmitted to a second data center through a first dedicated line, where the total traffic of service data is determined according to traffic of each service data that needs to be transmitted to the second data center through the first dedicated line.
In the embodiment of the application, the first data center can obtain the total flow of the service data which needs to be transmitted to the second data center through the first special line currently. Optionally, in this embodiment of the application, the first data center may obtain each flow of each service data in real time, and then determine a total flow of each service data by calculating a sum of each flow of each service data, or in this embodiment of the application, each flow of each service data is stored in the database in advance, and the first data center obtains each flow of each service data in the database and calculates the total flow of each service data.
Optionally, in this embodiment of the present application, each flow of each service data may be determined by using a five-tuple of each service data, for example, in this embodiment of the present application, each acquired service data that needs to be transmitted to the second data center through the dedicated line 1 includes service data 1, service data 2, and service data 3, where the five-tuple of the service data 1 is: source ip 10.1.1.1, destination ip10.2.1.1, source port 1000, destination port 2000, communication protocol TCP, flow size b 1; the quintuple of the service data 2 is: source ip 10.1.2.1, destination ip10.2.2.1, source port 2000, destination port 3000, communication protocol TCP, flow size b 2; the quintuple of the service data 3 is: source ip 10.1.3.1, destination ip10.2.3.1, source port 1000, destination port 2000, communication protocol TCP, traffic size b 3.
Step S202, if the first data center determines to perform the offloading processing according to the total traffic of the service data, determining a second dedicated line matched with the traffic of the first service data, where the first service data is any one of the service data that needs to be currently transmitted through the first dedicated line.
In this embodiment of the application, if the first data center determines to perform the splitting processing according to the total traffic of the service data, the second dedicated line matched with the traffic of the first service data is determined.
In the embodiment of the application, the first data center determines whether to perform the shunting according to the total amount of the service data. In an optional embodiment, the first data center determines whether offloading is required according to the total amount of the service data and an offloading threshold.
In this embodiment of the present application, the offloading threshold may be determined by a bandwidth utilization rate of the dedicated line, where the bandwidth utilization rate is determined according to a traffic of the bandwidth occupied by the dedicated line and a maximum supported traffic of the dedicated line bandwidth, for example, the maximum supported traffic of the dedicated line 1 is 100M, and for a traffic corresponding to the service data, the occupied bandwidth is 50M, and the bandwidth utilization rate is 50%. In the embodiment of the application, when the bandwidth utilization rate exceeds the shunting threshold, shunting is performed. Similarly, when the bandwidth utilization does not exceed the offloading threshold, the first data center determines that offloading is not required for the service data transmitted via the first dedicated line.
In this embodiment, in an optional embodiment, the offloading threshold may be determined by parameters such as a time delay and a packet loss rate, or the parameters such as an incoming time delay and a packet loss rate may be used as one of the offloading thresholds, and when the time delay and the packet loss rate of the first dedicated line are greater than the time delay threshold and the packet loss rate threshold in the offloading threshold, the first data center determines that offloading is required.
Optionally, in this embodiment of the application, the service data that needs to be transmitted through the first dedicated line may be understood as burst service data, where the burst service data conforms to one of the following characteristics: the traffic of the service data is increased rapidly within a set time, and the traffic of the service data keeps stable fluctuation after the traffic is increased rapidly; the traffic of the service data is increased rapidly within the set time, and the traffic of the service data keeps increasing stably after the traffic is increased rapidly.
Specifically, the burst service data includes:
1. the traffic bandwidth of the service data 1 is W, the service data is in a stable fluctuation state for a long time, the traffic bandwidth is increased to W1 within a short time t0, and the traffic bandwidth is stable fluctuation on W1, so that the service data 1 is burst service data;
2. the traffic bandwidth of the service data 1 is W, the service data 1 is in a steady fluctuation state for a long time, the traffic bandwidth is increased to W1 within a short time t0, and then the traffic bandwidth is increased to W2 steadily, so that the traffic of the service data 1 is burst service data.
Optionally, in this embodiment of the present application, whether each service data is burst service data is determined according to a quintuple of each service data.
In the embodiment of the application, after determining to perform the shunting processing, the first data center determines the second private line matched with any burst service data, and may also determine the first service data from each service data according to a certain rule.
In an optional embodiment, the service data with the largest flow in each service data may be used as the first service data, and an optional selection method is used. For example, in the embodiment of the present application, the service data that needs to be transmitted to the second data center through the first dedicated line are service data 1, service data 2, service data 3, and service data 4, a flow rate of the service data 1 is 300M, a flow rate of the service data 2 is 400M, a flow rate of the service data 3 is 200M, and a flow rate of the service data 4 is 250M. The sequence of the service data is service data 2, service data 1, service data 4 and service data 3, and the service data 2 is used as the first service data.
In this embodiment of the present application, the first service data may also be selected according to other methods, which are not described herein.
In this embodiment of the present application, determining the second dedicated line that matches the traffic of the first service data refers to determining a dedicated line that is different from the first dedicated line and is capable of bearing the traffic of the first service data, so in this embodiment of the present application, the unoccupied traffic of the second dedicated line is at least equal to the traffic of the first service data.
In an optional embodiment, the first data center may further sort, according to the unoccupied traffic, other private lines except the first private line, and may sort, from large to small, the unoccupied traffic to obtain a private line sequence, where the first main line in the private line sequence is used as the second main line.
For example, in the embodiment of the present application, the first data center and the second data center transmit the first service data through the dedicated line 1, the dedicated line 2, the dedicated line 3, and the dedicated line 4, where the unoccupied traffic of the dedicated line 2 is 300M, the unoccupied traffic of the dedicated line 3 is 600M, the unoccupied traffic of the dedicated line 4 is 500M, and the sequence of the dedicated lines is the dedicated line 3, the dedicated line 4, and the dedicated line 2, and the dedicated line 3 is used as the second dedicated line.
In this application, there is an optional embodiment, when the matching second dedicated line cannot be found in the traffic of the first service data, after the set time, the second dedicated line matching the traffic of the first service data is determined again.
Step S203, the first data center sends the first service data to the second data center through the second dedicated line, and returns to the step of the first data center acquiring total traffic of the service data currently required to be transmitted through the first dedicated line, where the total traffic of the service data currently required to be transmitted through the first dedicated line does not include the traffic of the first service data.
In the embodiment of the application, after the first data center determines the second dedicated line, the first service data is sent to the second data center through the second dedicated line, after the sending, the first data center obtains the total traffic of the service data which needs to be transmitted to the second data center through the first dedicated line, and at this time, the total traffic of the service data obtained by the first data center does not include the traffic of the first service data which is already sent to the second data center.
That is to say, in the embodiment of the present application, after the first data center sends the first service data to the second data center, the first data center further needs to determine the next first service data, and then determines the second private line matched with the next first service data.
For example, in the embodiment of the present application, after a first data center sends service data 2 in a sequence of service data to a second data center through a dedicated line 3, the first data center updates each service data in the sequence of service data, then determines a second dedicated line matched with the first service data, and sends the first service data through the second dedicated line.
In this embodiment of the present application, a first data center may send first service data to a second data center through an SR technique, and specifically, in this embodiment of the present application, the first data center creates first SR tunnel information including the second private line information, where the first SR tunnel information is used to indicate that the first service data needs to be transmitted to the second data center through the second private line, and the first data center adds the first SR tunnel information to a header of the first service data, and sends the first service data to the second data center according to the header of the first service data.
In this embodiment of the application, after the first data center sends the first service data to the second data center, the second data center may also send the response data to the first data center, and the second data center may also send the response data to the first data center through the second dedicated line.
That is to say, after the first data center establishes the first SR tunnel information by using the SR technology, the second data center also establishes the second SR tunnel information corresponding to the first SR tunnel information by using the SR technology, and the second SR tunnel information is used to indicate that the response data of the first service data is transmitted to the first data center through the second dedicated line.
In this embodiment, there may also be an optional embodiment, after the first data center sends the first service data to the second data center, when the first data center determines that the total traffic of the service data that needs to be transmitted to the second data center through the first dedicated line does not need to be split, the first data center further sends the second service data in the service data to the second data center through the first dedicated line.
Optionally, in this embodiment of the present application, a backflow threshold may be set to determine whether backflow is required. That is, in the embodiment of the present application, the first data center determines whether to perform the reflow processing according to the total traffic data flow.
In an alternative embodiment, the backflow threshold is determined at least according to the bandwidth usage rate of the first dedicated line, for example, when the bandwidth usage rate of the first dedicated line reaches 90%, the backflow threshold is set, and when the bandwidth usage rate of the first dedicated line falls back to 60%, the backflow threshold is set.
In the embodiment of the application, when the first data center determines that the reflow processing is required, the SR tunnel information is deleted, so that the first data center can send the service data to the second data center according to the first private line.
Meanwhile, in the embodiment of the application, the second data center also deletes the corresponding SR tunnel information, so that the second data center can send the response data of the first service data to the first data center through the first dedicated line.
An exemplary explanation of the shunting process and the reflow process of the first data center is shown in fig. 3, each service data that needs to be transmitted to the second data center through a specific dedicated line is service data 1, service data 2, service data 3, and service data 4, where a flow of the service data 1 is 200M, a flow of the service data 2 is 150M, a flow of the service data 3 is 100M, a flow of the service 4 is 50M, a total flow of each service data in the first data is determined to be 500M, a bandwidth usage rate of the set dedicated line is calculated to be 90% and a shunting threshold value is 85% for a total flow of current service data, so the first data center determines that the shunting process needs to be performed.
In the embodiment of the application, the first data center sorts the traffic of each service data from large to small to form service data, and the sequence is service data 1, service data 2, service data 3 and service data 4; similarly, the first data center sorts other private lines from large to small according to idle traffic to form a private line sequence, the other private lines include a private line 1, a private line 2, a private line 3 and a private line 4, the idle traffic of the private line 1 is 800M, the idle traffic of the private line 2 is 700M, the idle traffic of the private line 3 is 500M, and the sequence of the private line sequence is the private line 1, the private line 2, the private line 3 and the private line 4.
The method comprises the steps that a first data center determines that a special line matched with service data 1 is a special line 1, the service data 1 is sent to a second data center through the special line 1, after the first data center sends the service data, a service data sequence is updated, the updated service data sequence is service data 2, service data 3 and service data 4, the first data center determines that the total flow of current service data is 300M, and the bandwidth utilization rate of the special line is set to be 88% and is larger than a shunting threshold value aiming at the total flow of the current service data, so that shunting processing is needed.
The first data center updates a private line queue, the updated private line queue is a private line 2, a private line 1 (remaining 600M) and a private line 3, the service data 2 is sent to the second data center through the private line 2, then the first data center continues to determine the total flow of each service data currently for the set private line, in the embodiment of the present application, each service data for the set private line is a service data 3 and a service data 4, the total flow of each service data is 150M, the total flow of each service data is set with a private line bandwidth utilization rate of 50%, the set backflow threshold value is 60%, so the first data center determines to perform backflow processing, and the first data center sends the service data 3 to the second data center through the set private line.
In order to better explain the embodiment of the present application, the traffic control method provided in the embodiment of the present application is described below in combination with a specific implementation scenario, and in the embodiment of the present application, the method is applied to a traffic control system, where the traffic control system at least includes a first data center and a second data center, and the first data center and the second data center are connected by a plurality of dedicated lines.
In the embodiment of the present application, as shown in fig. 4, the method specifically includes:
