Description

Technical Field

[0001] The present invention relates to the technical field of network traffic statistics, and in particular to a virtual link network traffic statistics method, device, electronic equipment and computer-readable storage medium. Background Art

[0002] Current network traffic products generally use physical interfaces or sub-interfaces as basic units to count network traffic. However, this method of traffic statistics is inadequate in terms of statistical structure, statistical dimension, statistical efficiency, and statistical standardization. In other words, the basic units designed based on physical interfaces or sub-interfaces have a relatively coarse granularity when calculating traffic statistics.

[0003] Of course, many products now also provide more fine-grained statistical functions, such as by optimizing the format of data packets, the port of traffic statistics, or the user interface. However, these methods require the configuration of relatively cumbersome rules, which is inconvenient for users or traffic statistics personnel and is not conducive to the portability and speed of network traffic statistics.

[0004] Therefore, it is necessary to improve the existing network traffic statistics method. Summary of the invention

[0005] In view of this, it is necessary to provide a virtual link network traffic statistics method, device, electronic device and storage medium, which can achieve fine traffic statistics granularity while being simple to configure, easy to expand and convenient to operate.

[0008] Creating at least one virtual link under each link based on traffic characteristics, and assigning a virtual link ID to each virtual link, wherein the traffic characteristics are determined according to network traffic statistics requirements;

[0009] The data message is ID-tagged based on the link ID and the virtual link ID to count the network traffic.

[0010] In a possible implementation, each link is bound to one or more physical interfaces. When network traffic passes through the bound one or more physical interfaces, the network traffic is marked with the link ID of the link corresponding to the one or more physical interfaces as the first identifier.

[0012] In a possible implementation, at least one virtual link is created under each link based on traffic characteristics, and a virtual link ID is assigned to each virtual link, including:

[0013] Obtaining a flow label and a flow range, and creating at least one virtual link corresponding to the flow label and the flow range under each link;

[0014] A unique virtual link ID is assigned to each virtual link.

[0015] In a possible implementation, when the network traffic meets the traffic label and traffic range corresponding to the virtual link, the network traffic is marked with a link ID corresponding to the virtual link as the second identifier.

[0016] In a possible implementation, performing ID marking on a data message based on the link ID and the virtual link ID to count network traffic includes:

[0017] When the network traffic passes through the link and the virtual link successively, the data message is marked with an ID by the link ID and the virtual link ID respectively, and stored as traffic two-dimensional data;

[0018] All the two-dimensional traffic data are traversed, statistics are collected on the two-dimensional traffic data, and the data are output in the form of logs or reports in real time.

[0019] In a possible implementation, the two-dimensional traffic data is a two-dimensional array, and the link ID and the virtual link ID are used as subscripts of two dimensions respectively, and the two-dimensional array is accumulated in a cumulative form.

[0020] In a second aspect, the present invention further provides a virtual link network traffic statistics device, comprising:

[0021] A link creation module is used to create several links based on the physical interface and assign a link ID to each link;

[0022] A virtual link creation module, used to create at least one virtual link under each link based on traffic characteristics, and to assign a virtual link ID to each virtual link, wherein the traffic characteristics are determined according to network traffic statistics requirements;

[0023] The traffic statistics module is used to perform ID marking on data messages based on the link ID and the virtual link ID to count network traffic.

[0024] In a third aspect, the present invention further provides an electronic device, including a memory and a processor, wherein:

[0025] The memory is used to store programs;

[0026] The processor is coupled to the memory and is used to execute the program stored in the memory to implement the steps in the virtual link network traffic statistics method described in any one of the possible implementation modes.

[0027] In a fourth aspect, the present invention also provides a computer-readable storage medium, on which a program or instruction is stored, and when the program or instruction is executed by a processor, the steps in the virtual link network traffic statistics method described in any one of the above possible implementation methods are implemented.

[0028] The beneficial effects of the present invention are as follows: the present invention first creates a plurality of links based on a physical interface, and allocates a link ID to each link to realize the first marking of flow statistics; secondly, based on flow characteristics, at least one virtual link is created under each link, and a virtual link ID is allocated to each virtual link to realize the second marking of flow statistics; finally, based on the link ID and the virtual link ID, data packets are ID-marked to count network flow, that is, flow statistics are performed on data packets that need to be counted by marking twice, which is convenient and quick.

[0029] The present invention adds a logical layer called "virtual link" on the basis of the conventional physical port, and classifies the traffic statistics in more detail based on the user's traffic statistics needs. It is simple to configure and easy to expand. Compared with the existing technology, it reduces the configuration difficulty and improves the statistical efficiency.

[0037] Reference to an "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] The present invention provides a virtual link network traffic statistics method, device, electronic device and storage medium, which are respectively described below.

[0039] Figure 1 A flow chart of an embodiment of a method for counting virtual link network traffic provided by the present invention is as follows: Figure 1 As shown, the virtual link network traffic statistics method includes:

[0040] S101, creating several links based on the physical interface, and assigning a link ID to each link;

[0041] S102, creating at least one virtual link under each link based on traffic characteristics, and assigning a virtual link ID to each virtual link, wherein the traffic characteristics are determined according to network traffic statistics requirements;

[0042] S103: Mark the data message with an ID based on the link ID and the virtual link ID to count network traffic.

[0043] It is understandable that in step S101, the purpose of creating a link is that when each link is bound to one or more physical interfaces, each link will be assigned an ID as a unique identifier, so that any traffic received by the interface bound to the link will be marked with the link ID. This first mark is used to perform preliminary identification of data packets.

[0044] It should be noted that in step S102, the virtual link is a virtual link and does not actually exist. Its purpose is to be able to build a link on the link to serve as a marker according to network traffic requirements (ie, customer requirements) so as to specifically identify data packets.

[0045] Compared with the prior art, the present invention first creates several links based on the physical interface, and assigns a link ID to each link to achieve the first marking of traffic statistics; secondly, creates at least one virtual link under each link based on the traffic characteristics, and assigns a virtual link ID to each virtual link to achieve the second marking of traffic statistics; finally, based on the link ID and the virtual link ID, the data message is ID-marked to count the network traffic, that is, the traffic statistics of the data message to be counted are performed by marking twice, which is convenient and fast.

[0046] The present invention adds a logical layer called "virtual link" on the basis of the conventional physical port, and classifies the traffic statistics in more detail based on the user's traffic statistics needs. It is simple to configure and easy to expand. Compared with the existing technology, it reduces the configuration difficulty and improves the statistical efficiency.

[0047] In some embodiments of the present invention, each link is bound to one or more physical interfaces. When network traffic passes through the bound one or more physical interfaces, the network traffic is marked with the link ID of the link corresponding to the one or more physical interfaces as the first identifier.

[0048] In some embodiments of the present invention, traffic is further divided based on certain characteristics of traffic, and the set carrying these traffic is called a virtual link. The traffic characteristics include a traffic label and a traffic range, and the traffic label includes at least one of the following items: vlan, vxlan, mpls label, IP network segment and MAC address; the traffic range is the port range corresponding to the traffic label.

[0049] In some embodiments of the present invention, at least one virtual link is created under each link based on traffic characteristics, and a virtual link ID is assigned to each virtual link, including:

[0050] Obtaining a flow label and a flow range, and creating at least one virtual link corresponding to the flow label and the flow range under each link;

[0051] A unique virtual link ID is assigned to each virtual link.

[0052] In a specific embodiment, taking the traffic label as vlan as an example, the traffic range represents the vlan port range. For example, if the vlan port range value is 100 to 1000, the virtual link matches the data traffic with the lan port range value of 100 to 1000.

[0053] In a possible implementation, when the network traffic meets the traffic label and traffic range corresponding to the virtual link, the network traffic is marked with a link ID corresponding to the virtual link as the second identifier.

[0054] In a possible implementation, performing ID marking on a data message based on the link ID and the virtual link ID to count network traffic includes:

[0055] When the network traffic passes through the link and the virtual link successively, the data message is marked with an ID by the link ID and the virtual link ID respectively, and stored as traffic two-dimensional data;

[0056] All the two-dimensional traffic data are traversed, statistics are collected on the two-dimensional traffic data, and the data are output in the form of logs or reports in real time.

[0057] In a possible implementation, the two-dimensional traffic data is a two-dimensional array, and the link ID and the virtual link ID are used as subscripts of two dimensions respectively, and the two-dimensional array is accumulated in a cumulative form.

[0058] In the specific embodiments, see Figure 2 , Figure 2Another embodiment of the virtual link network traffic statistics method provided by the present invention is a flow chart. If a user wants to count the data traffic size of a certain port with a vlan value ranging from 100 to 1000, the implementation steps are as follows:

[0059] Step 1: Create a link and bind the physical interface. Assume that the system assigns a link ID of 1 to the link. Then create a virtual link under the link. The filtering condition of the virtual link is VLAN value 100-1000. Assume that the system assigns a virtual link ID of 2 to the virtual link. At this time, the system will create a traffic statistics structure with a link ID of 1 and a virtual link ID of 2 and store it in the memory. It can be understood that the system in this embodiment refers to a traffic statistics system, which is generally executed by software on the PC.

[0060] Step 2: When a vlan200 data packet enters the system from this physical interface, the system first marks the packet with a link ID of 1 according to the port, and then checks all virtual links under this link. There is a virtual link with a filtering condition of vlan100-1000, so the vlan value of this packet is checked to be 200, which meets the filtering condition, and determines that the traffic belongs to this virtual link, and marks the packet with a virtual link ID of 2.

[0061] Step 3: The message enters the traffic statistics module, and according to the mark in the message, its data is recorded in the traffic statistics data structure with link ID 1 and virtual link ID 2. The general data structure can use a two-dimensional array, with the link ID and virtual link ID as the subscripts of the two dimensions respectively, and the calculation method is generally to accumulate the original data.

[0062] Step 4: The system starts a task separately, regularly traverses all traffic statistics data structures, calculates the traffic data of each link and its virtual link, and outputs it in real time in the form of logs or reports. Finally, the traffic data of the VLAN values ​​100 to 1000 corresponding to the virtual link 2 under link 1 can be seen from the interface.

[0063] Step 5: If a packet with vlan 10 enters from the same interface, the system will mark the packet with a link ID of 1. However, the packet cannot match the filtering rules of any virtual link, so the packet will not be marked with a virtual link ID (in other implementations, the virtual link ID of 0 can be considered a special value, indicating that the packet does not belong to any virtual link, and can be marked with a virtual link ID of 0). Then, when statistics are performed later, the packet will only be counted in the traffic of link 1, and will not be counted in any virtual link.

[0064] It should be noted that the above is explained with vlan as the traffic label. If other traffic labels are used, such as vxlan, mpls labels, IP segments and MAC addresses, this solution can also be implemented. The specific process is not repeated here.

[0065] In order to better implement the virtual link network traffic statistics method in the embodiment of the present invention, based on the virtual link network traffic statistics method, the embodiment of the present invention also provides a virtual link network traffic statistics device, such as Figure 3 As shown, the virtual link network traffic statistics device 300 includes:
