With the digitalized transformation of enterprises, the functions and types of the services provided by the enterprises are diversified and personalized, so that the bandwidth resources required by each service are more and more increased. In the traditional wide area network, a private line mode is adopted between an enterprise branch and an enterprise headquarter to forward the service flow.
The special line mode has the advantages of stable bandwidth resource and high quality, but is high in price. Therefore, most enterprises choose to use the Internet (Internet) with lower cost for communication between branches and headquarters of the enterprise.

For example, an enterprise purchases 100G bandwidth resources from an operator. In a practical environment, the bandwidth resources provided by the operators may float between 80 and 120G. If the enterprise gateway configures the exit bandwidth speed limit according to the 100G bandwidth, when the operator provides the 80G bandwidth, there will be 20G traffic that is randomly discarded when the wide area network is transmitted, and the discarded traffic may be core traffic of the enterprise, so that the enterprise suffers a loss.

The bandwidth adjustment method provided in the embodiment of the present application is described in detail below. Referring to fig. 1, fig. 1 is a flowchart of a bandwidth adjustment method provided in an embodiment of the present application. The method is applied to network equipment, and the bandwidth adjustment method provided by the embodiment of the application can comprise the following steps.
Step 110, periodically detecting a current device packet loss rate of the network device, a current interface bandwidth utilization rate of the first interface, and a current network packet loss rate of a network where the network device is located;
specifically, the network device includes a first interface that has been configured with an original interface speed limit value. The network device periodically detects the current device packet loss rate of the network device, the current interface bandwidth utilization rate of the first interface and the current network packet loss rate of the network where the network device is located.
As shown in fig. 2, fig. 2 is a schematic networking diagram of an enterprise branch-enterprise headquarters according to an embodiment of the present application. In fig. 2, an in-enterprise terminal accesses an enterprise branched network device that accesses a network (e.g., a wide area network) through a first interface. One end of the enterprise headquarter gateway is connected to the network, and the other end is connected to the enterprise headquarter.
After receiving the traffic flow sent by the terminal in the enterprise, the network device periodically (e.g., every 10s, 20s, 30s, etc.) detects the current device packet loss rate, the current interface bandwidth utilization rate, and the current network packet loss rate.
The network device calculates the packet loss rate of the current device according to the following formula (1).
Current device packet loss ratio = bandwidth of discarded message/total bandwidth of first interface (1)
The bandwidth of the discarded message is specifically the quotient of the length of the discarded message of the network device and the preset time. The length of the discarded message, the network device may count a preset time through a token bucket mechanism, for example: 10s; the first interface total bandwidth is in particular a bandwidth configured by the operator for each interface, e.g. 300M.
The network device calculates the current interface bandwidth utilization by the following equation (2).
Current interface bandwidth utilization = used bandwidth of first interface/total bandwidth of first interface (2)
The used bandwidth of the first interface specifically refers to counting the length/preset time of all messages sent by the first interface within a preset time (e.g., 10 s).
The network equipment calculates the current network packet loss rate through the following formula (3).
Current network packet loss rate= (number of sending messages at sending end-number of receiving messages at receiving end)/number of sending messages at sending end (3)
The sending end performs characteristic marking on the appointed message and sends the appointed message to the receiving end through an in-band detection technology (namely, the real service message is subjected to characteristic marking or detection information is embedded in the real service message), the receiving end counts the message with the characteristic marking, and the counted number of the messages is fed back to the sending end.
In practical applications, the current network packet loss rate may also be obtained by other means. For example, a public network is deployed between the enterprise branch and the enterprise headquarter, and the packet is generally encrypted and protected through the IPSec protocol, and at this time, the packet loss rate may be calculated by using the anti-replay sequence number. For example, the packet loss rate calculation can also be performed by the extended BFD.
Step 120, if any one or a combination of the current equipment packet loss rate, the current interface bandwidth utilization rate and the current network packet loss rate meets a preset condition, adjusting the original interface speed limit value to obtain a current interface speed limit value;
specifically, according to the description of step 110, after the network device obtains the current device packet loss rate, the current interface bandwidth utilization rate, and the current network packet loss rate, it is identified whether any one or a combination of the current device packet loss rate, the current interface bandwidth utilization rate, and the current network packet loss rate satisfies a preset condition.
And if any one or combination meets the preset condition, the network equipment adjusts the original interface speed limit value to obtain the current interface speed limit value.
Optionally, in the process of periodically detecting the three parameters, in one implementation manner, when the network device first senses that the current network packet loss rate is different from the current previous network packet loss rate, if the current network packet loss rate is greater than 0, the network device reduces the original interface speed limit value to obtain the current interface speed limit value; if the current network packet loss rate is equal to 0 and the current device packet loss rate is greater than 0, the network device increases the original interface speed limit value to obtain the current interface speed limit value.
For example, the current network packet loss rate is C2 (20%), and the current previous network packet loss rate is C1 (10%). At this time, C2 is greater than 0, and the network device reduces the original interface speed limit value, to obtain the current interface speed limit value.
For another example, the current network packet loss rate is C2 (5%), and the current previous network packet loss rate is C1 (10%). At this time, C2 is still greater than 0, and the network device still reduces the original interface speed limit value, to obtain the current interface speed limit value.
For another example, the current network packet loss rate is C2 (0%), and the current previous network packet loss rate is C1 (10%). At this time, C2 is equal to 0, that is, no packet loss occurs in network transmission, and the network device identifies the current device packet loss rate A2 (the current previous device packet loss rate is A1). If A2 is greater than 0, the network device increases the original interface speed limit value to obtain the current interface speed limit value.
In another implementation manner, when the network device first perceives that the current device packet loss rate is different from the current previous device packet loss rate, if the current network packet loss rate is greater than 0, the network device reduces the original interface speed limit value to obtain the current interface speed limit value; if the current network packet loss rate is equal to 0 and the current equipment packet loss rate is equal to 0, the network equipment does not adjust the original interface speed limit value; if the current network packet loss rate is equal to 0 and the current device packet loss rate is greater than 0, the network device increases the original interface speed limit value to obtain the current interface speed limit value.
For example, the current network packet loss rate is C2 (20%), and the current previous network packet loss rate is C1 (10%). At this time, C2 is greater than 0, and the network device reduces the original interface speed limit value, to obtain the current interface speed limit value.
For another example, the current network packet loss rate is C2 (5%), and the current previous network packet loss rate is C1 (10%). At this time, C2 is still greater than 0, and the network device still reduces the original interface speed limit value, to obtain the current interface speed limit value.
For another example, the current network packet loss rate is C2 (0%), the network device identifies the change of the device packet loss rates A1 and A2, and if the current previous device packet loss rate A1 (20%) is changed to the current device packet loss rate A2 (0%), that is, the network device has no packet loss, the original interface speed limit value is suitable, and no adjustment is needed.
For another example, the current network packet loss rate is C2 (0%), and the network device again recognizes the change in the device packet loss rates A1, A2. Current previous device packet loss rate A1 (20%), current device packet loss rate A2 (10%). At this time, A2 is greater than 0, and the network device increases the original interface speed limit value, to obtain the current interface speed limit value.
In another implementation, when the network device first senses that the current interface bandwidth utilization is different from the current previous interface bandwidth utilization, if the current device packet loss rate and the current network packet loss rate are both 0, the current interface bandwidth utilization is greater than the current previous interface bandwidth utilization and the current interface bandwidth utilization is greater than the first value, and the current previous interface bandwidth utilization is less than the first value, the network device increases the original interface speed limit value to obtain the current interface speed limit value.
For example, the network device perceives a change in the interface bandwidth utilization B1, B2. Current previous interface bandwidth utilization B1 (90%), current interface bandwidth utilization (98%). The network device identifies a current device packet loss rate A2 and a current network packet loss rate C2. If both A2 and C2 are 0, and B2> B1, B2>95% and B1<95%, the network device increases the original interface speed limit value to obtain the current interface speed limit value.
Optionally, the specific process of the network device reducing the original interface speed limit value to obtain the current interface speed limit value is as follows: the network equipment calculates a difference value between the first value and the current network packet loss rate; the network device takes the product of the original interface speed limit value and the difference value as the current interface speed limit value.
For example, the first value is specifically 1. The network device calculates the current interface speed limit value by the following formula (4).
x2=x1X (1-C2) formula (4)
Wherein X2 is the current interface speed limit value; x1 is an original interface speed limit value; c2 is the current network packet loss rate.
Optionally, the specific process of the network device increasing the original interface speed limit value to obtain the current interface speed limit value is as follows: the network equipment acquires the total bandwidth of the first interface configuration; the network equipment calculates the difference between the total bandwidth and the original interface speed limit value; the network device calculates a quotient of the difference value and the second value; the network device takes the sum of the original interface speed limit value and the quotient as the current interface speed limit value.
For example, the network device calculates the current interface speed limit value by the following equation (5).
X2=x1+|x0-x1|/2 formula (5)
Wherein X2 is the current interface speed limit value; x1 is an original interface speed limit value; x0 is the total bandwidth.
And 130, updating the original interface speed limit value to the current interface speed limit value at the first interface.
Specifically, after the network device obtains the current interface speed limit value according to the description of step 120, the original interface speed limit value is updated to the current interface speed limit value at the first interface. And then, the network equipment carries out speed-limiting forwarding processing on the service flow according to the current interface speed-limiting value.
As shown in fig. 3, fig. 3 is a graph of a change in a current interface speed limit value according to an embodiment of the present application. In fig. 3, X0 is the total bandwidth, and the current interface speed limit value is smoothly adjusted when it is close to X0; the current interface speed limit value is steeply adjusted when it is far from X0.
Therefore, by applying the bandwidth adjustment method provided by the application, the network equipment periodically detects the current equipment packet loss rate of the network equipment, the current interface bandwidth utilization rate of the first interface and the current network packet loss rate of the network where the network equipment is located; if any one or combination of the current equipment packet loss rate, the current interface bandwidth utilization rate and the current network packet loss rate meets a preset condition, the network equipment adjusts the original interface speed limit value to obtain the current interface speed limit value; at the first interface, the network device updates the original interface speed limit value to the current interface speed limit value.
Therefore, the self-adaptive bandwidth speed limit adjustment is carried out by detecting the packet loss rate in the network equipment, the network packet loss rate and the interface bandwidth utilization rate, so that the packet loss is limited in an enterprise, and the high-priority service priority forwarding can be selectively ensured by matching with the traditional QoS function; and adjusting the interface speed limit value in a controllable range to maximize the utilization of the operator network. The method solves the problems that in the existing communication process of enterprise branches and enterprise headquarters by using Interne, the network is unstable, the network condition cannot be perceived in real time, and bandwidth resource dynamic adjustment is made.
Based on the same inventive concept, the embodiment of the application also provides a bandwidth adjusting device corresponding to the bandwidth adjusting method.

and an updating unit 430, configured to update, at the first interface, the original interface speed limit value to the current interface speed limit value.
Optionally, the adjusting unit 420 is specifically configured to, when the current network packet loss rate is different from the current previous network packet loss rate, reduce the original interface speed limit value to obtain the current interface speed limit value if the current network packet loss rate is greater than 0;
and if the current network packet loss rate is equal to 0 and the current equipment packet loss rate is greater than 0, increasing the original interface speed limit value to obtain the current interface speed limit value.
Optionally, the adjusting unit 420 is specifically configured to, when the current device packet loss rate is different from the current previous device packet loss rate, reduce the original interface speed limit value to obtain the current interface speed limit value if the current network packet loss rate is greater than 0;

and if the current network packet loss rate is equal to 0 and the current equipment packet loss rate is greater than 0, increasing the original interface speed limit value to obtain the current interface speed limit value.
Optionally, the adjusting unit 420 is specifically configured to, when the current interface bandwidth utilization is different from the current previous interface bandwidth utilization, increase the original interface speed limit value if the current device packet loss rate and the current network packet loss rate are both 0, where the current interface bandwidth utilization is greater than the current previous interface bandwidth utilization and the current interface bandwidth utilization is greater than a first value, and the current previous interface bandwidth utilization is less than the first value, so as to obtain the current interface speed limit value.
