Description

Bandwidth limiting method, device and system

Technical Field

The present invention relates to the field of network technologies, and in particular, to a method, an apparatus, and a system for bandwidth limitation.

Background

When the occupied bandwidth in the network is high, the data transmission efficiency is also reduced, thereby affecting the network quality. In order to ensure the network quality, in the prior art, the bandwidth limitation is generally performed on the basis of a single link.

Specifically, the server in the network is used for realizing specific services, and when each client needs to request the server for services, a single link is established between each client and the server. For each single link, when the occupied bandwidth of the single link exceeds a preset bandwidth threshold, the occupied bandwidth of the single link is limited.

For each single link, bandwidth limitation may be achieved by applying the above approach. However, for the whole network, the number of clients establishing single links with each server is variable and uncontrollable, so that bandwidth limitation can be implemented only for each single link by applying the above method, and when the number of single links is too large, the bandwidth occupation of the whole network is still high.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

First, a bandwidth limiting system applied to an embodiment of the present invention will be described. Referring to fig. 1, fig. 1 is a schematic diagram of a bandwidth limiting system according to an embodiment of the present invention, which includes a bandwidth limiting user interface, a configuration node, a management node, a service node 1, and a service node 2, where the service node 1 includes a management child node 1, a service child node 11, a service child node 12, … …, and a service child node 1n, and the service node 2 includes a management child node 2, a service child node 21, a service child node 22, a service child node … …, and a service child node 2 n.

The service sub-node 11, the service sub-node 12, … … and the service sub-node 1n are used for providing services for users and interacting data with the management sub-node 1. Likewise, the service sub-node 21, the service sub-node 22, … …, and the service sub-node 2n are also used to provide services to users, and perform data interaction with the management sub-node 2. Each service child node may be one electronic device or a plurality of electronic devices.

The management sub-node 1 and the management sub-node 2 perform data interaction with each service sub-node on one hand and perform data interaction with the management node on the other hand. The processes of the above two aspects can be performed simultaneously by two threads. The management sub-node 1 and the management sub-node 2 may be electronic devices independent of the service sub-node in the service node to which they belong, or may be electronic devices serving as the service sub-node in the service node to which they belong, that is, one electronic device serves as both the management sub-node and the service sub-node. Specifically, a hash value of each electronic device identifier serving as a service child node may be calculated by a hash algorithm, and then one electronic device may be selected from the electronic devices serving as the service child node as a management child node according to the calculated hash value.

The bandwidth limiting user interface is: and the interface displayed on the client used by the staff or the user is used for inputting the bandwidth limitation information such as domain names, bandwidth thresholds and the like.

The configuration node is used for receiving bandwidth limitation information sent by a client used by a worker or a user and storing the bandwidth limitation information.

The management node is used for carrying out data interaction with each management sub-node and acquiring bandwidth limitation information set by staff or users from the configuration node.

The following describes a bandwidth limiting method provided by an embodiment of the present invention.

Referring to fig. 2, fig. 2 is a schematic flowchart of a first bandwidth limiting method applied to a management node in a bandwidth limiting system according to an embodiment of the present invention, where the method includes S201 to S203.

S201: and determining a target domain name and sending the target domain name to each management child node.

The target domain name may be a single domain name, for example: www.xxx.com or www.xxx.cn. The target domain name may also be a plurality of domain names belonging to a domain name group, for example: the suffix is a plurality of domain names of.com.

The target domain name may be a domain name input by a user or a worker on the bandwidth limitation user interface, or may be a domain name selected from various domain names provided by the user or the worker on the bandwidth limitation user interface. And may also be information selected from information of various service response policies provided on the bandwidth limited user interface by the user or staff. The bandwidth limitation user interface sends information configured by a user or a worker to the configuration node, the configuration node stores the configured information, and the management node acquires a target domain name configured by the user or the worker stored in the configuration node at a fixed time or according to a preset interval time.

The management node may send the target domain name obtained within a preset time interval to each management child node.

S202: and acquiring the quantity of established links sent by each management sub-node and the node bandwidth.

The established links are: managing the established link between the target service sub-node and the client in the service node where the sub-node is located, wherein the target service sub-node is: a service child node is provided that accesses the target domain name service.

Specifically, since the target service sub-node is used for providing access to the target domain name service, when the user accesses the target domain name on the client used by the user, the client establishes a link with the target service sub-node. For example: when the user accesses the target domain name www.xxx.com on the client used by the user, the target service sub-node accessing the target domain name www.xxx.com is provided as the service sub-node A, and then the client establishes a link with the service sub-node A.

The node bandwidth represents the bandwidth occupied by the established link corresponding to the service node where the management child node is located. Specifically, the node bandwidth may be an occupied bandwidth of each established link, or may be a total occupied bandwidth of the established links corresponding to the service node where the management child node is located.

The established links corresponding to the service nodes are as follows: and the established link between the target service child node in the service node and the client.

After each management sub-node receives the target domain name sent by the management node, each management sub-node determines a service sub-node for providing access to the target domain name service, namely the target service sub-node, counts the number of established links between the target service sub-node and the client, and obtains the node bandwidth. Each management sub-node may send the counted number of established links and node bandwidth to the management node according to a preset interval time.

S203: if the total occupied bandwidth exceeds a preset bandwidth threshold, determining the available bandwidth corresponding to each service node according to the obtained quantity of established links and the node bandwidth, and sending the determined available bandwidth to each management sub-node, so that each management sub-node limits the occupied bandwidth of the established links corresponding to the service node according to the received available bandwidth.

The total occupied bandwidth is as follows: and the sum of the obtained node bandwidths. For example: the bandwidth limiting system includes a service node 1 and a service node 2, a node bandwidth corresponding to the service node 1 is 100Mbps (megabits per second), a node bandwidth corresponding to the service node 2 is 200Mbps, and then a total occupied bandwidth is 100Mbps +200Mbps, which is 300 Mbps.

When the target domain name is a single domain name, the total occupied bandwidth is the sum of the bandwidths occupied by the established links corresponding to the single domain name; when the target domain name belongs to a plurality of domain names in the domain name group, the total occupied bandwidth is the sum of the occupied bandwidths of the established links corresponding to the plurality of domain names. The established link corresponding to the domain name can be understood as: a link between a service child node accessing the domain name service and the client is provided.

The preset bandwidth threshold may be set on a bandwidth limiting user interface by a user or a worker, and the management node obtains the preset bandwidth threshold set on the bandwidth limiting user interface by the user or the worker. For example: the preset bandwidth threshold may be 1000 Mbps.

When the total occupied bandwidth exceeds a preset bandwidth threshold value, the total occupied bandwidth is high.

When the number of links established between each target service sub-node in the service node and the client is large, the number of clients accessing the target domain name is large, so that more available bandwidth can be determined for the service node to ensure that the service sub-node can provide normal service for accessing the target domain name; similarly, when the link established between each target service sub-node in the service node and the client occupies a higher bandwidth, it indicates that the data volume transmitted between each target service sub-node and the client is larger, so that more available bandwidth can be determined for the service node, and normal data transmission between each target service sub-node and the client is determined. Therefore, the available bandwidth corresponding to each service node is determined from two aspects, and the network state in each service node is fully considered, so that the normal data transmission of each established link in each service node and the normal service provided by each service sub-node can be ensured while the bandwidth is limited.

In an embodiment of the present invention, according to the obtained number of established links and node bandwidth, the available bandwidth quote corresponding to each service node can be calculated according to the following formula:

Quota＝[(a/A)*X+(b/B)*Y]*C

Therefore, the available bandwidth corresponding to each service node is calculated according to the calculation formula, and the available bandwidth corresponding to each service node can be determined more accurately.

Specifically, the management node may send a message including the determined available bandwidth to each management child node, where the message may further include an identifier that the total occupied bandwidth exceeds a preset bandwidth threshold. In this way, the management child node can perform bandwidth limitation on the established link according to the available bandwidth and the identifier that the total occupied bandwidth carried in the message exceeds the preset bandwidth threshold.

In addition, the message may be a message generated according to a preset message format.

In an embodiment of the present invention, after the determining the target domain name in S201, the method may further include:

The new link described above can be understood as: and providing a link newly established between the target service sub-node accessing the target domain name and the client.

The information of the service response policy based on the new link corresponding to the target domain name may be identification information of the service response policy based on the new link corresponding to the target domain name, or may be specific content of the service response policy based on the new link corresponding to the target domain name.

Specifically, the information of the service response policy based on the new link corresponding to the target domain name may be information input by the user or the staff on the bandwidth-limited user interface, or information selected from information of each service response policy provided by the user or the staff on the bandwidth-limited user interface. The bandwidth limitation user interface sends information configured by a user or a worker to the configuration node, the configuration node stores the configured information, and the management node acquires the information of the service response strategy configured by the user or the worker stored in the configuration node at a fixed time or according to a preset interval time.

In an embodiment of the present invention, the service response policy may include one of the following policies:

the first method comprises the following steps: and sending a response to the client aiming at the service request sent by the client based on the new link.

The first strategy described above can be understood as: when the client sends a service request to the target service child node based on the new link, the target service child node rejects the policy to provide the service to the client.

The response contains a status code and information indicating denial of service.

The status code is used to indicate the reason for denial of service. For example: the status code may be 403, which indicates that the service child node understands the content of the service request, but rejects to execute the service request sent by the client based on the new link; the status code may also be 404. 404 indicates that the content that the client wishes to be served based on the service request sent by the new link is not stored on the serving child node. The status code may be stored in a header of the response message denying the provision of the service.

Therefore, service is refused to be provided for the client, extra occupied bandwidth of the network is not increased, the existing occupied bandwidth of the network is guaranteed to be unchanged, and the reason for refusing to respond to the client to send the request can be determined according to the state code returned to the client.

And the second method comprises the following steps: and sending a service response based on the newly linked service request to the client according to the preset bandwidth.

The second strategy described above can be understood as: when the client sends a service request to the target service child node based on the new link, the target service child node may send a policy of the provided service response to the client according to the preset bandwidth.

When the target service child node sends the service response based on the newly linked service request to the client, the service response can be sent according to a preset bandwidth, and the service response can also be sent according to a bandwidth which does not exceed the preset bandwidth.

Therefore, data transmission is carried out according to the preset bandwidth, and the whole occupied bandwidth of the network can be limited.

And the third is that: and forwarding the service request to a preset service sub-node aiming at the service request sent by the client based on the new link, so that the preset service sub-node responds to the service request.

The third strategy described above can be understood as: when the client sends the service request to the target service sub-node based on the new link, the target service sub-node forwards the service request to the preset service sub-node, so that the preset service sub-node sends the policy of the provided service response to the client.

Specifically, the target service child node may change the destination IP address or the target domain name carried in the service request to an IP address or a domain name of a preset service child node, so that the service request may be forwarded to the preset service child node. Therefore, the service request is forwarded to the preset service sub-node, the service request sent by the client based on the new link can be normally responded, and the quality of the service provided for the user is ensured.

In this way, since the service response policy can be a plurality of service response policies, the service child node in the service node where the management child node is located can flexibly respond to the service request based on the new link.

Referring to fig. 3, fig. 3 is a flowchart illustrating a second bandwidth limiting method according to an embodiment of the present invention, which is applied to a management child node included in a service node in a bandwidth limiting system, where the method includes S301 to S302.

S301: and receiving the target domain name sent by the management node.

S302: the number of established links and the node bandwidth are obtained.

Specifically, the management sub-node may monitor each target service sub-node included in the service node where the management sub-node is located, and after monitoring the target service sub-node establishing a link with the client, record the link established between the target service sub-node and the client and an occupied bandwidth of the link established between the target service sub-node and the client, thereby determining the number of established links and the node bandwidth.

S303: and sending the obtained quantity of the established links and the node bandwidth to the management node, so that the management node determines the available bandwidth corresponding to each service node according to the received quantity of the established links and the node bandwidth.

S304: and receiving the available bandwidth which is sent by the management node and corresponds to the service node where the management sub-node is located, and limiting the occupied bandwidth of the established link according to the received available bandwidth.

When the available bandwidth received by the management sub-node is the available bandwidth of each established link corresponding to the service node where the management sub-node is located, the management sub-node may limit the occupied bandwidth of each established link according to the available bandwidth.

In an embodiment of the present invention, when the available bandwidth received by the management sub-node is the total available bandwidth corresponding to the serving node, the management sub-node may determine the available bandwidth of each established link according to the received available bandwidth and the obtained number of established links; and limiting the occupied bandwidth of each established link according to the determined available bandwidth of each established link.

Specifically, the management child node determines the available bandwidth of each established link according to the received available bandwidth and the number of established links, and there may be the following two determination manners.

The first mode is as follows: the available bandwidth for each established link is evenly distributed based on the received available bandwidth and the number of established links. For example: when the available bandwidth received by the management sub-node is 1000Mbps and the number of established links is 10, the available bandwidth of each established link is 100 Mbps.

The second mode is as follows: the available bandwidth of each established link is calculated according to the received available bandwidth and the number of the established links. For example: when the available bandwidth received by the management sub-node is 1000Mbps, the number of established links is 2, and the weight of the established link 1 is 0.4, the available bandwidth of the established link 1 is 400Mbps, and the weight of the established link 2 is 0.6, the available bandwidth of the established link 2 is 600 Mbps. In this way, the management sub-node can flexibly determine the available bandwidth of each established link, thereby limiting the occupied bandwidth of each established link.

When the occupied bandwidth of the established link corresponding to the service node is limited, the occupied bandwidth parameter information of each established link can be modified into the received available bandwidth.

As can be seen from the above, when the scheme provided by this embodiment is applied to perform bandwidth limitation, the management child node in the service node sends the number of established links and the node bandwidth to the management node, and receives the available bandwidth sent by the management node and determined according to the received number of established links and the node bandwidth. Therefore, the management node receives data and sends available bandwidth in units of service nodes, and compared with the client related to the prior art, the number of the service nodes is controllable and less variable. Therefore, when the available bandwidth is determined by taking the service nodes as a unit, the bandwidth in the network is not easily occupied too much due to the uncontrollable number of the service nodes.

S306: and informing a target service sub-node in the service node to respond to the service based on the new link according to the service response strategy when the total occupied bandwidth exceeds a preset bandwidth threshold.

When the total occupied bandwidth exceeds the preset bandwidth threshold, the management sub-node may send a request for executing the service response policy to each target service sub-node, and each target service sub-node responds to the service based on the new link according to the service response policy.

As can be seen from the above, when the scheme provided by this embodiment is applied to perform bandwidth limitation, the service response policy may be multiple service response policies, so that the service child node in the service node where the management child node is located can flexibly respond to the service request based on the new link.

sending a response to the client aiming at the service request sent by the client based on the new link, wherein the response comprises a status code and information for indicating that the service is refused to be provided, and the status code is used for indicating the reason for refusing to provide the service; therefore, the whole occupied bandwidth in the network can be ensured, and the reason for refusing to respond to the request sent by the client can be determined according to the status code returned to the client.

Sending a service response based on the newly linked service request to the client according to the preset bandwidth; therefore, data transmission is carried out according to the preset bandwidth, and the whole occupied bandwidth of the network can be limited.

And forwarding the service request to a preset service sub-node aiming at the service request sent by the client based on the new link, so that the preset service sub-node responds to the service request. Therefore, the service request is forwarded to the preset service sub-node, the service request sent by the client based on the new link can be normally responded, and the quality of the service provided for the user is ensured.
