Description
Technical Field

Background
With the rapid development of information technology, the internet gradually develops towards networking, digitalization and intellectualization. In order to meet diversified demands for the users, improve the user experience, and reduce the cost of service for the users, the smart bank is becoming a development trend of the commercial bank.
In the construction of an intelligent bank, a plurality of terminal devices are required to be connected with each other to process mass data, and therefore, the network quality when the terminal devices process data becomes one of the key factors for providing service quality. In the aspect of direct experience of users, terminal devices such as intelligent teller machines, self-service terminal devices and self-service queuing machines are end-to-end services which are directly contacted by the users, and the network quality of the terminal devices determines the experience of the users. For accurate and efficient services provided by banks, it is generally necessary to acquire mass data of user transaction behaviors, for example, the mass data of user transaction behaviors are acquired through terminal devices by using technologies such as biometric identification, behavior capture, image acquisition and the like. Therefore, the information interaction of the intelligent device has strict requirements on the network transmission quality. Therefore, the improvement of the network quality is beneficial to establishing a more efficient intelligent bank service mode, the reasonable utilization of network resources, the timely solution of network problems and the reduction of network delay are the key for improving the network service quality.
In carrying out the presently disclosed concept, the inventors have found that there are at least the following problems in the related art.
In the network environment of the current network point, there are two general methods for solving the problem of data transmission in the network. The first method is based on a traditional network architecture, in which multiple paths are generally provided for transmitting data to the same destination address, and the traditional network architecture is mainly configured with an Equal-Cost multi-path (ECMP) protocol at a switch to ensure multi-path load balancing. However, if the bandwidth difference between the two paths is large, the network resource utilization rate is poor. The second method is to use 5G technology in the smart network, and each terminal device can access the 5G network, but some existing terminal devices do not have the function of accessing the 5G network. It is often necessary to customize a specific terminal device to access the 5G network, which results in excessive costs. Therefore, the above two methods are difficult to effectively monitor the network state and reasonably utilize the network resources for a certain network point.

Fig. 1 schematically illustrates an application scenario of a data forwarding method and a data forwarding apparatus according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of an application scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
As shown in fig. 1, the application scenario 100 according to this embodiment may control, for example, a device 110, a plurality of nodes 121, 122, 123, 124, 125, terminal devices 131, 132, 133.
The data forwarding method of the embodiment of the present disclosure may be implemented by, for example, a Software-defined network (SDN). The software defined network has the characteristic of separation of control and forwarding. The software defined network includes, for example, a control layer and a forwarding layer. The control layer can perform global monitoring and resource scheduling on the network, and the forwarding layer can forward network data based on control layer instructions. The network resources can be more reasonably used by utilizing the characteristic of separation of control and forwarding of the software defined network.
For example, the control device 110 serves as a control layer of the software defined network, and the plurality of nodes 121, 122, 123, 124, 125 serve as a forwarding layer of the software defined network. The plurality of nodes 121, 122, 123, 124, 125 may forward data of the terminal devices 131, 132, 133 under the control of the control device 110.
Among them, the terminal devices 131, 132, 133 may be various electronic devices having a display screen and supporting web browsing, including but not limited to smart phones, tablet computers, laptop portable computers, desktop computers, and the like.
According to an embodiment of the present disclosure, the plurality of nodes 121, 122, 123, 124, 125 may for example form at least one forwarding path. In the embodiment of the present disclosure, for example, two forwarding paths are formed by the plurality of nodes 121, 122, 123, 124, and 125. The first forwarding path may include nodes 121, 122, 123, 124 and the second forwarding path may include nodes 121, 125, 124. The node of the embodiment of the present disclosure may be a switch.
The control device 110, the plurality of nodes 121, 122, 123, 124, 125, and the terminal devices 131, 132, 133 are located in a local area network, for example. In one embodiment, the control device 110, the plurality of nodes 121, 122, 123, 124, 125, and the terminal devices 131, 132, 133 may be in a local area network in which a banking outlet is located.
For example, when terminal device 131 needs to transmit data to terminal device 133, the data to be transmitted may be the data to be forwarded according to the embodiment of the present disclosure. The control device 110 may determine a target forwarding path from the two forwarding paths to send the data to be forwarded. For example, after the control device 110 determines that the first forwarding path is the target forwarding path, the control device 110 may control the target forwarding path to forward the data to be forwarded.
It should be noted that the data forwarding method provided by the embodiment of the present disclosure may be generally executed by the control device 110. Accordingly, the data forwarding apparatus provided by the embodiment of the present disclosure may be generally disposed in the control device 110.
The embodiment of the disclosure provides a multilink network load balancing management system for intelligent equipment network resource management of an intelligent network point based on a framework of a software defined network, can monitor the global state of the network and manage network resources through the system, and can timely adjust or schedule the network resources according to service priority when the network has overlarge delay.
In the following, a data forwarding method according to an exemplary embodiment of the present disclosure is described with reference to fig. 2 to 5 in conjunction with an application scenario of fig. 1. It should be noted that the above application scenarios are merely illustrated for the convenience of understanding the spirit and principles of the present disclosure, and the embodiments of the present disclosure are not limited in this respect. Rather, embodiments of the present disclosure may be applied to any scenario where applicable.
Fig. 2 schematically shows a flow chart of a data forwarding method performed by a control device according to an embodiment of the present disclosure.
As shown in fig. 2, the data forwarding method performed by the control device of the embodiment of the present disclosure may include, for example, the following operations S210 to S240.
In operation S210, at least one forwarding path is determined, where each forwarding path is used for forwarding data to be forwarded.
According to the embodiment of the present disclosure, the data to be forwarded may be, for example, data to be transmitted by the first device to the second device. The first device and the second device may be, for example, terminal devices shown in fig. 1. Wherein, the data to be forwarded can be forwarded through at least one forwarding path. Before forwarding the data to be forwarded, the embodiments of the present disclosure may determine, by the control device, at least one forwarding path that may be used for forwarding the data to be forwarded.
In operation S220, node information of each forwarding path and bandwidth information of each forwarding path are determined.
In operation S230, a target forwarding path of the at least one forwarding path is determined based on the node information and the bandwidth information.
In the embodiment of the present disclosure, the node information of each forwarding path includes, for example, the number of nodes of each forwarding path and the number of nodes of the same node between different forwarding paths. For a forwarding path, the greater the number of nodes on the forwarding path, the lower the efficiency of forwarding data and the slower the speed of forwarding data. In addition, for one forwarding path, the larger the bandwidth of the forwarding path is, the higher the efficiency of data forwarding is, and the faster the data forwarding speed is. Therefore, one forwarding path may be determined as the target forwarding path from the at least one forwarding path based on the node information and the bandwidth information of each forwarding path. Wherein the forwarding efficiency of the target forwarding path is higher than that of other forwarding paths in the at least one forwarding path, for example.
Next, in operation S240, the control target forwarding path forwards the data to be forwarded.
After the control device determines the target forwarding path according to the node information and the bandwidth information of each forwarding path, the control device may control the target forwarding path to forward the data to be forwarded of the first device to the second device.
It can be understood that, in the embodiment of the present disclosure, the control device determines a target forwarding path with high forwarding efficiency from the multiple forwarding paths based on the node information and the bandwidth information of each forwarding path, and controls the target forwarding path to forward the data to be forwarded, so as to improve the forwarding efficiency of the data and reduce the time consumption for forwarding the data. In addition, the control equipment can monitor the global state of the network, and selects a path with high forwarding efficiency from a plurality of forwarding paths for data forwarding, so that the reasonable management and utilization of network resources are realized, the service quality of the network is improved, and the load balance of the network is ensured.
Fig. 3 schematically illustrates a flow chart for determining a target forwarding path according to an embodiment of the present disclosure.
As shown in fig. 3, the determining of the target forwarding path of the at least one forwarding path based on the node information and the bandwidth information in operation S230 includes, for example, the following operations S231 to S234. The specific implementation process of operations S231 to S234 will be described below with reference to fig. 1 and 3.
In operation S231, a total number of nodes in at least one forwarding path is determined based on the number of nodes of each forwarding path and the number of nodes of the same node between different forwarding paths.
As shown in fig. 1, for example, the at least one forwarding path includes two forwarding paths. The first forwarding path may include nodes 121, 122, 123, 124 and the second forwarding path may include nodes 121, 125, 124. Wherein the number of nodes of the first forwarding path is, for example, 4, the number of nodes of the second forwarding path is, for example, 3, and the number of nodes of the same node (node 121, node 124) between the first forwarding path and the second forwarding path is 2. Therefore, in the embodiment of the present disclosure, the total number of nodes in at least one forwarding path is, for example, the sum of the number of nodes in the multiple forwarding paths minus the number of nodes in the same node, that is, the total number of nodes in at least one forwarding path is: 4+3-2 ═ 5.
In operation S232, a weight of each forwarding path is determined based on the number of nodes and the total number of nodes of each forwarding path.
According to the embodiment of the present disclosure, the larger the number of nodes per forwarding path, the smaller the weight that can represent the forwarding path. That is, the larger the number of nodes per forwarding path is, the more nodes the data needs to pass through when forwarding the data, which results in lower forwarding efficiency and longer forwarding time. Therefore, the larger the number of nodes of a forwarding path, the smaller the weight representing the forwarding path.
For example, the weight of each forwarding path of the embodiments of the present disclosure may be expressed as:
the embodiment of the present disclosure includes n forwarding paths, for example. i may represent the current forwarding path.
May represent the total number of nodes for the n forwarding paths. pw (i) may represent the number of nodes of the current forwarding path. Wherein the weight C of each pathiFor example both greater than 1 or less than 10.
As shown in fig. 1, an embodiment of the present disclosure includes, for example, n-2 forwarding paths.
The weight of the first forwarding path (i ═ 1) is, for example:
the weight of the second forwarding path (i ═ 2) is, for example:
in operation S233, a transmission capability of each forwarding path is determined based on the weight of each forwarding path and the bandwidth information of each forwarding path.
According to embodiments of the present disclosure, the transmission capacity of each forwarding path may be characterized, for example, as a product between a weight value and a bandwidth value of each forwarding path. Wherein, when the product between the weight value and the bandwidth value of each forwarding path is larger, it may indicate that the transmission capability is larger.
Next, in operation S234, a target forwarding path of the at least one forwarding path is determined based on the transmission capability.
For example, a forwarding path with the maximum transmission capability in at least one forwarding path is used as a target forwarding path, and the target forwarding path is controlled by the control device to forward the data to be forwarded, so that the data forwarding efficiency is improved, and the time consumption of data forwarding is reduced.
Fig. 4 schematically shows a flow chart of a data forwarding method performed by a control device according to another embodiment of the present disclosure.
As shown in fig. 4, the data forwarding method performed by the control device of the embodiment of the present disclosure may include, for example, operations S210 to S240 and the following operations S410 to S430. The operations S210 to S240 are, for example, the same as or similar to the operations shown in fig. 2, and are not described herein again.
Wherein, S410 to operation S430 of the embodiment of the present disclosure are performed, for example, before operation S220.
In operation S410, a target service to which data to be forwarded belongs is determined.
According to the embodiment of the present disclosure, in order to meet the service requirements, corresponding priority forwarding paths may be set for different services. For example, the at least one forwarding path may include a plurality of forwarding paths. For the target service, one or more forwarding paths may be set in advance from a plurality of forwarding paths to forward data belonging to the target service.
In operation S420, a priority forwarding path of the at least one forwarding path is determined, wherein the priority forwarding path is used for forwarding data of the target traffic.
Next, in operation S430, the priority forwarding path is controlled to forward the data to be forwarded.
For example, when data to be forwarded of the target service needs to be forwarded, the control device may determine a priority forwarding path for forwarding the data of the target service from the multiple forwarding paths, and then control the priority forwarding path to forward the data to be forwarded of the target service.
Therefore, the data forwarding method of the embodiment of the present disclosure can adapt to various service requirements by setting the corresponding priority forwarding paths for different services.
In another embodiment, when the data to be forwarded is sent through the target forwarding path, the data may be sequentially forwarded through a plurality of nodes in the target forwarding path. For example, the target forwarding path includes at least one node, and the step of forwarding the data to be forwarded on the control target forwarding path in operation S240 includes: and for the current node in the at least one node, receiving the data to be forwarded from the upper-level node or the first equipment by the current node, and forwarding the data to be forwarded to the lower-level node or the second equipment by the current node.
As shown in fig. 1, when the data to be forwarded is transmitted from the first device (terminal 131) to the second device (terminal 133), the data to be forwarded may be transmitted to the second device via the target forwarding path, for example. The target forwarding path may include node 121, node 122, node 123, and node 124. The node 121 may receive data to be forwarded from the first device and send the data to be forwarded to the node 122, the node 122 may send the received data to be forwarded to the node 123, the node 123 may send the received data to be forwarded to the node 124, and then the node 124 sends the data to be forwarded to the second device.
When the current node is the node 121, the node 121 may receive the data to be forwarded from the first device, and send the data to be forwarded to the next node (node 122). When the current node is the node 122, the node 122 may receive the data to be forwarded from the previous node (node 121) and send the data to be forwarded to the next node (node 123). When the current node is the node 123, the node 123 may receive the data to be forwarded from the previous node (the node 122) and send the data to be forwarded to the next node (the node 124). When the current node is the node 124, the node 124 may receive the data to be forwarded from the previous node (the node 123) and send the data to be forwarded to the second device.
According to the embodiment of the present disclosure, the current node may be configured to forward a plurality of data to be forwarded, where the plurality of data to be forwarded corresponds to the plurality of services one to one. For example, the current node may be node 123, and this node 123 may be used to receive and forward data to be forwarded from different services.
In addition, different services of the disclosed embodiments have different priorities. For example, the different services may include service 1, service 2, service 3. The priority of the service 1, the priority of the service 2, and the priority of the service 3 may be a high priority, a medium priority, and a low priority in sequence.
When the current node forwards a plurality of data to be forwarded, the service to which each data to be forwarded belongs in the plurality of data to be forwarded can be determined, then the service priority of each service in the plurality of services is determined, and the plurality of data to be forwarded are forwarded based on the service priority.
For example, after the current node receives the data to be forwarded 1, the data to be forwarded 2, and the data to be forwarded 3, it may be determined that the data to be forwarded 1, the data to be forwarded 2, and the data to be forwarded 3 belong to the service 1, the service 2, and the service 3, respectively. Next, the current node determines that the priorities of the service 1, the service 2, and the service 3 are high priority, medium priority, and low priority in sequence. The current node can forward a plurality of data to be forwarded in sequence according to the priority. For example, data to be forwarded 1 belonging to a high priority service may be forwarded preferentially, data to be forwarded 2 belonging to a medium priority service may be forwarded preferentially, and data to be forwarded 3 belonging to a low priority service may be forwarded subsequently.
In the embodiment of the present disclosure, a service person may set different priorities for different services to obtain a priority setting result, where the priority setting result includes, for example, a correspondence between a service identifier and a priority, and the correspondence includes, for example, "service 1 corresponds to a high priority, service 2 corresponds to a medium priority, and service 3 corresponds to a low priority. And then the control device sends the priority setting result to all nodes (including at least one node of the embodiment of the disclosure, for example) by issuing the flow table. When the current node in the target forwarding path receives the data to be forwarded, the service to which the data to be forwarded belongs can be determined from the data to be forwarded. For example, the data to be forwarded may include a network packet, and the current node may acknowledge the service to which the network packet belongs from the TOS field in the network packet. Then, the current node searches the priority corresponding to the service from the priority setting result, and forwards the network packet based on the priority. The TOS field in the network message is used, for example, to record the service described in the network message.
In the embodiment of the present disclosure, the control device may send request information to each node in real time to request to acquire relevant information of each node. After each node receives the request information of the control device, the attribute information of other nodes or terminal devices adjacent to the node can be acquired, the attribute information of the node and the attribute information of the adjacent nodes or terminal devices are sent to the control device, and the control device acquires the topological structure of the network based on the attribute information of each node, the connection relationship between the nodes and the association relationship between the nodes and the terminal devices. Wherein the attribute information may include a node name. The topology of the network includes, for example, a first device (terminal device), a second device (terminal device), and a connection relationship between a plurality of nodes. Wherein the plurality of nodes are configured to form at least one forwarding path as described in the embodiments of the present disclosure, so as to forward the interaction data between the first device and the second device through the at least one forwarding path. The interaction data between the first device and the second device includes, for example, data to be forwarded, which is to be sent by the first device to the second device, or data to be forwarded, which is to be sent by the second device to the first device.
Then, the control device may determine whether the plurality of nodes includes a failed node. For example, the control device may send a message to each node in a polling manner, and determine whether the node fails by whether each node feeds back. If a node has no feedback, it may be indicated as a failed node. In one case, the node feeds back immediately, but if the current feedback information of the node is not consistent with the previous feedback information, it may also be indicated that the node is a failed node.
In the embodiment of the present disclosure, when the plurality of nodes include the failed node, the control device may mark the failed node in the topology structure, so that the user may know the failed node in time, and take remedial measures in time. For example, the control device may mark the failed node in red in the topology structure, so as to send a warning to the maintenance personnel, thereby facilitating the maintenance personnel to locate the failure problem in time and solve the failure problem quickly.
Through the technical scheme of the embodiment of the disclosure, no matter in a conventional network or an intelligent network, the popularization of the intelligent equipment puts forward higher requirements on the network stability. The disclosed embodiment can better guarantee the stability of the network based on the software defined network architecture under the advantages of low cost and low maintenance. When the path delay is too large, the forwarding path can be switched through a multipath load balancing mechanism.
In addition, the embodiment of the disclosure can determine the path with the large transmission capability through the weight and the bandwidth of the path, and forward the data through the path with the large transmission capability, so that the utilization rate of the network resources is greatly improved.
According to the technical scheme of the embodiment of the disclosure, the network state can be checked through the Web interface, the forwarding path can be switched, and the forwarding priorities of different services can be formulated. Thereby greatly improving the maintainability of network resources. The Web interface may show, for example, a topology of a network.
