Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a QinQ message processing method, a QinQ message processing device, a computer-readable medium, and an electronic device. Background Art

[0002] With the rapid development of the Internet of Things, a large number of devices are connected to the Internet, and the number of devices (i.e. users) has reached tens of millions, resulting in huge network traffic. The QinQ (802.1Q-in-802.1Q) protocol is a Layer 2 tunneling protocol based on the IEEE 802.1Q technology. QinQ is a technology that expands the VLAN (Virtual local Area Network) space. It achieves the function of expanding the VLAN space by adding another layer of 802.1Q tags on the basis of 802.1Q tagged messages, so that private network VLANs can be transparently transmitted to the public network. The QinQ termination is mainly used to realize the VLAN termination of messages carrying two or more layers of VLAN tags.

[0003] In the existing QinQ network message processing process, the network card driver determines the network physical interface for receiving the message, and the network physical interface for receiving the message matches the corresponding VLAN interface according to the outer VLAN tag information carried by the message, and then strips off the outer VLAN tag of the message; then the VLAN interface matches the corresponding QinQ interface according to the inner VLAN tag information carried by the message, and strips off the inner VLAN tag of the message; finally, the message is forwarded at Layer 3 or handed over to other services for processing.

[0004] In the existing QinQ message processing process, the QinQ interface relies on the VLAN interface for interface matching. The message needs to pass through the VLAN interface before it can find the QinQ interface, that is, it needs to pass through two layers of interfaces to achieve QinQ termination.

[0048] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as being limited to the examples set forth herein; on the contrary, these embodiments are provided so that the present disclosure will be more comprehensive and complete, and the concepts of the example embodiments are fully conveyed to those skilled in the art. The described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known technical solutions are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0049] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0050] With the rapid development of the Internet of Things, the number of user terminal devices connected to the Ethernet has increased significantly, reaching tens of millions, and the network traffic is huge. How to efficiently transmit information between huge network architectures has become a technical difficulty.

[0051] A virtual local area network (VLAN) is a group of logical devices and users that are not restricted by physical location and can be organized based on functions, departments, applications, and other factors. A network is logically divided into several small virtual networks, namely VLANs (virtual local area network). VLANs work at the data link layer of the OSI reference model. A VLAN is a switching network. All users in the same VLAN are in the same broadcast domain. Each VLAN is connected through a routing device to achieve communication.

[0052] With QinQ technology, the operator network can provide a VLAN ID for different VLANs from the same user network, saving the operator's VLAN ID and solving the problem of increasingly tight VLAN ID resources in the operator network. Therefore, it has become the mainstream technology in this field. The existing message processing process is explained using QinQ messages as an example.

[0053] like Figure 1 The figure shows a schematic diagram of the existing QinQ message processing scenario. If the user state wants to send a message to the remote end, the following steps need to be performed:

[0054] Each device in user mode determines the message to be sent, and the kernel protocol stack encapsulates the message to be sent into a message data packet to form a message data packet queue.

[0055] After the network message is routed, the packet interface is set to QinQ interface eth0.0.0~eth0.0.4094, and the packets are delivered to a certain QinQ interface one by one. The QinQ interface encapsulates the inner VLAN tag for the packet and directs it to one of the VLAN interfaces eth0.0~eth0.4094.

[0056] The VLAN interface encapsulates the outer VLAN tag for the message data packet and directs it to the network physical interface.

[0057] The network physical interface delivers the sent data packet to the network card driver for processing; the network card driver sets the sending parameters.

[0058] The network interface controller (eg, network card NIC) controls the sending of message data packets according to the set sending parameters.

[0059] In the above existing message processing process, for example, QinQ messages, which have two or more VLAN tags, need to add or strip VLAN tags layer by layer during their sending and receiving process. There are interdependencies between network interfaces, which are mainly reflected in the associated dependencies in management status, MTU (maximum transmission unit), interface coupling, and packet sending and receiving processes.

[0060] Specifically, the dependencies include: Management status: The management status of the VLAN interface will be synchronized to the QinQ interface. MTU: The MTU value of the QinQ interface cannot be greater than the minimum value of the VLAN interface and the network physical interface. Interface coupling: When a VLAN interface is deleted, the QinQ interface it manages will also be deleted synchronously. Packet sending and receiving process: QinQ packets must pass through the VLAN interface on which they depend to complete sending and receiving.

[0061] The dependency between the above network interfaces (QinQ interface and VLAN interface) cannot meet the message immediacy requirement when the number of user devices increases sharply, and the management and maintenance cost is very high.

[0062] Based on the above problems, the present invention designs a QinQ message processing method.

[0063] The technical solution of the embodiment of the present disclosure is described in detail below:

[0064] refer to Figure 2 As shown, a QinQ message processing method according to an exemplary embodiment of the present disclosure may include the following steps:

[0065] Step S210, determining a matching relationship between the double-layer VLAN tag information and the QinQ interface information; the QinQ interface information includes a QinQ interface identifier;

[0066] Step S220, configuring the matching relationship in the network physical interface;

[0067] Step S230, according to the matching relationship, matching the double-layer VLAN tag information carried by the QinQ message with the QinQ interface identifier through the network physical interface to determine the QinQ interface identifier corresponding to the QinQ message;

[0068] Step S240: Process the QinQ message through the QinQ interface corresponding to the QinQ interface identifier according to the service information.

[0069] In the QinQ message processing method provided in this example implementation, the matching relationship between the double-layer VLAN tag information and the QinQ interface information can be first determined; the matching relationship can be configured in the network physical interface; according to the matching relationship, the double-layer VLAN tag information carried by the QinQ message is matched with the QinQ interface identifier through the network physical interface to determine the QinQ interface identifier corresponding to the QinQ message; according to the service information, the QinQ message is processed through the QinQ interface corresponding to the QinQ interface identifier. On the one hand, the dependency between the QinQ interface and the VLAN interface in the QinQ message processing process is eliminated, so that the QinQ message can be directly processed through the QinQ interface, thereby improving the QinQ message processing efficiency; on the other hand, the layer-by-layer identification and stripping process of the double-layer VLAN tag information is avoided, thereby reducing the consumption of hardware resources. In addition, the creation, management status, MTU (maximum transmission unit), and packet receiving and sending operations of the QinQ interface are completely independent of the VLAN interface, and the MTU of the QinQ interface is independent of the network physical interface, which is convenient for the management and maintenance of the entire system.

[0070] Next, in another embodiment, the above steps are described in more detail.

[0071] In step S210, the matching relationship between the double-layer VLAN tag information and the QinQ interface information is determined. In this example implementation, the QinQ interface information may include information such as the QinQ interface identifier, the QinQ interface transmission rate, the QinQ interface status (e.g., management status (up)), and the QinQ interface IP. The double-layer VLAN tag information may include inner VLAN tag information, i.e., inner VLAN tag information, and outer VLAN tag information, i.e., outer VLAN tag information. The inner VLAN tag information is a private network tag, and the outer VLAN tag information is a public network tag. The message containing the double-layer VLAN tag information can realize the private network VLAN transparent transmission to the public network.

[0072] In this example implementation, the inner VLAN tag information may also carry multiple layers of VLAN tag information, for example, two layers of VLAN tag information or three layers of VLAN tag information. In this embodiment, the VLAN tag information within the outermost layer may be collectively referred to as inner VLAN tag information. One inner VLAN tag information corresponds to one virtual local area network.

[0073] In this example implementation, the matching relationship between the double-layer VLAN tag information and the QinQ interface information may be determined through steps S310 - S320 .

[0074] In step S310, the double-layer VLAN tag information is added to the QinQ interface information to form the QinQ interface information containing the double-layer tag. In this example implementation, the double-layer VLAN tag information may include an outer VLAN tag and an inner VLAN tag. The outer VLAN tag may include a 2-byte ETYPE field and a 2-byte tag field, and the tag field may include a priority, a CFI (Canonical Format Indicator), and a VLAN ID field. The VLAN ID is 12 bits and can represent 4K VLANs. The format of the inner VLAN tag is the same as that of the outer VLAN tag. The above double-layer VLAN tag information is added to the QinQ interface information.

[0075] For example, for the Linux operating system, by reconfiguring the QinQ interface information in the 802.1Q module of the Linux kernel, the above double-layer VLAN tag information is configured in the QinQ interface information of the 802.1Q module, so that the QinQ interface information contains double-layer VLAN tag information. In this way, when sending and receiving messages, the QinQ interface can be directly searched, and the double-layer VLAN tag can be identified and stripped at one time, simplifying the message processing process.

[0076] In step S320, a matching relationship between the double-layer VLAN tag information and the QinQ interface identifier is established according to the QinQ interface information containing the double-layer tag. In this example implementation, a matching relationship can be established between the double-layer VLAN tag information in the QinQ interface information containing the double-layer tag and the corresponding QinQ interface identifier. The matching relationship is essentially a data structure, and the data structure can be presented in the form of a lookup table item or a self-balancing binary search tree. Preferably, this example establishes a corresponding self-balancing binary search tree according to the matching relationship between the double-layer VLAN tag information and the QinQ interface identifier, and one node in the self-balancing binary search tree corresponds to one QinQ interface identifier.

[0077] For example, in this example implementation, the nodes of the self-balancing binary search tree have two attributes. In addition to the general mandatory requirements of the binary search tree, the following requirements are added:

[0078] (1) A node has two attributes.

[0079] (2) The root node is the first attribute.

[0080] (3) Each leaf node (NIL node, empty node) has the first attribute.

[0081] (4) Both child nodes of each second attribute node are first attributes. (There cannot be two consecutive second attribute nodes on all paths from each leaf to the root)

[0082] (5) All paths from any node to each of its leaves contain the same number of first attribute nodes.

[0083] The above constraints enforce the key property of a self-balancing binary search tree: the longest possible path from the root to a leaf is no longer than twice the shortest possible path. As a result, the tree is roughly balanced. The worst-case time required for operations such as inserting, deleting, and looking up a value is proportional to the height of the tree. This theoretical upper limit on the height allows the self-balancing binary search tree to be efficient in the worst case, ensuring efficient lookup of double-layer VLAN tag information and QinQ interface identifiers.

[0084] In step S220, the matching relationship is configured in the network physical interface. In this example implementation, the network physical interface may be a network card interface in a software system. It may be used to implement data exchange between a user and an external device. This example mainly refers to the network physical interface (i.e., the main interface) in the data exchange process. In general, the matching relationship between the interface and the VLAN tag is recorded in the data structure of the corresponding interface at the upper level. In this example, the matching relationship between the double-layer VLAN tag information and the QinQ interface identifier is directly configured in the network physical interface, so that the network physical interface can directly search for the corresponding QinQ interface according to the double-layer VLAN tag information carried by the message without going through the VLAN interface, completely eliminating the dependency between the QinQ interface and the VLAN interface, and changing the network interface from the previous hierarchical relationship to the current parallel relationship. When the message carries a double-layer VLAN tag, the corresponding QinQ interface is directly searched in the network physical interface. When the message carries a single-layer VLAN tag, the corresponding VLAN interface is directly searched in the network physical interface. Whether it is a single-layer or double-layer VLAN tag, it only needs to go through the interface search and forwarding process once, which improves the message processing efficiency.

[0085] For example, the storage information of the QinQ interface information is configured in the 802.1Q module of the Linux kernel so that the matching relationship is stored in the network physical interface. When the matching relationship is a lookup table item, the corresponding lookup table item is stored in the network physical interface; when the matching relationship is a self-balancing binary search tree, the self-balancing binary search tree is stored in the network physical interface. In the process of sending and receiving messages, if the kernel protocol stack finds that the message carries a double-layer protocol as VLAN, the 802.1Q module is called to process the message; and the corresponding QinQ interface is found through the self-balancing binary search tree stored in the network physical interface; when the corresponding QinQ interface is not found, the message is directly discarded. If a matching QinQ interface is found, the message can be transmitted to the QinQ interface.

[0086] In step S230, according to the matching relationship, the double-layer VLAN tag information carried by the QinQ message is matched with the QinQ interface identifier through the network physical interface to determine the QinQ interface identifier corresponding to the QinQ message.

[0087] In this example implementation, the node information identical to the double-layer VLAN tag information carried by the QinQ message is searched in the self-balancing binary search tree stored in the network physical interface; the corresponding QinQ interface identifier is determined according to the node information found. The specific implementation process is that after the Linux kernel protocol stack recognizes that the message carries VLAN tag information, it calls the 802.1Q module, and the 802.1Q module strips off the two layers of VLAN tags of the message, and searches for the corresponding node information in the matching relationship of the network physical interface, such as the self-balancing binary search tree, and determines the corresponding QinQ interface identifier according to the corresponding node information found. When no matching information is found in the matching relationship, the current message data packet is discarded.

[0088] In step S240, the QinQ message is processed through the QinQ interface corresponding to the QinQ interface identifier according to the service information.

[0089] In this example implementation, reference Figure 4 As shown, message processing is performed through steps S410-S420.

[0090] In step S410, the service type information is determined, and the service type information includes termination information and forwarding information. In this example implementation, the service type information can be determined by the service information identifier carried in the message, or can be obtained by the kernel through other interactive forms.

[0091] The service type information may be QinQ message termination information or QinQ message subsequent forwarding information. The QinQ message termination information may be information required to implement VLAN termination of messages carrying two or more VLAN tags. The QinQ message subsequent forwarding information may be information required for layer 2 forwarding, layer 3 forwarding, or other service processing.

[0092] In step S420, based on the service type information, the QinQ message is terminated or forwarded through the QinQ interface corresponding to the QinQ interface identifier. In this example implementation, since the double-layer VLAN tag information is added to the QinQ interface information in advance, when receiving and sending messages, the QinQ interface can be directly searched, and there is no need to go through the VLAN interface. The QinQ message can be directly terminated or forwarded through the QinQ interface, which simplifies the processing flow in the message receiving and sending process and improves the message processing efficiency.

[0093] In another embodiment of the present disclosure, for a message carrying a single layer of VLAN tag information, a VLAN interface can be directly used to process the message. This example retains a VLAN interface corresponding to a public network tag for processing a message carrying a single layer of VLAN tag information.

[0094] In this example implementation, VLAN message processing is implemented through the following steps: First, single-layer VLAN tag information is added to VLAN interface information, so that the VLAN interface information contains VLAN tag information; then, the VLAN interface information containing single-layer VLAN tag information is configured in the network physical interface, so that the message finds a matching VLAN interface in the network physical interface, and the VLAN interface is used to directly process the message.

[0095] For example, refer to Figure 5 , the message processing method disclosed in the present invention is used to implement the message receiving and sending process.

[0096] (1) Message sending process:

[0097] (1a) Each application in user mode sends a message to the remote end.

[0098] (1b) The kernel protocol stack encapsulates the message into a message queue to form a network data packet.

[0099] (1c) The network data packet is routed by the system, the packet sending interface is set as the QinQ interface, and the network data packets are delivered to the QinQ interface one by one.

[0100] (1d) The QinQ interface calls the 802.1Q module to encapsulate two layers of VLAN tags for network data packets.

[0101] (1e) Call the 802.1Q module to redirect the sending device of the network data packet to the network physical interface, and submit the network data packet to the network physical interface for processing.

[0102] (1f) The network physical interface submits the network data packet to the network card driver for processing.

[0103] (1g) The network card driver sets the sending parameters, and the network interface controller controls the sending of network data packets.

[0104] (2) Message receiving process:

[0105] (2a) The network interface controller controls the reception of network data packets from the remote end and notifies the network card driver.

[0106] (2b) The network card driver performs preliminary processing such as information verification on the network data packet, sets the network physical interface for receiving the packet, and submits the network data packet to the kernel protocol stack.

[0107] (2c) The kernel protocol stack parses the network data packet and, based on the parsing results, calls the 802.1Q module to process the message.

[0108] (2d) If the parsing result is a single-layer VLAN protocol, the 802.1Q module strips off the VLAN tag of the message and searches for the corresponding VLAN interface in the network physical interface accordingly; if the parsing result is a two-layer VLAN protocol, the 802.1Q module strips off the two-layer VLAN tags of the message and searches for the corresponding QinQ interface in the self-balancing binary search tree of the network physical interface accordingly.

[0109] (2e) If no corresponding QinQ interface or VLAN interface is found, the message is discarded directly.

[0110] (2f) If the QinQ interface is successfully matched, the packet receiving device is redirected to the QinQ interface.

[0111] If the VLAN interface is successfully matched, the packet receiving device is redirected to the VLAN interface.

[0112] (2g) The message is delivered to the upper layer protocol of the kernel protocol stack.

[0113] (2h) The message is delivered to each application in user mode.

[0114] The present disclosure can first determine the matching relationship between the double-layer VLAN tag information and the QinQ interface information; configure the matching relationship in the network physical interface; according to the matching relationship, match the double-layer VLAN tag information carried by the QinQ message with the QinQ interface identifier through the network physical interface to determine the QinQ interface identifier corresponding to the QinQ message; according to the business information, process the QinQ message through the QinQ interface corresponding to the QinQ interface identifier. On the one hand, the dependency between the QinQ interface and the VLAN interface in the QinQ message processing process is eliminated, so that the QinQ message can be directly processed through the QinQ interface, improving the efficiency of QinQ message processing; on the other hand, the layer-by-layer identification and stripping process of the double-layer VLAN tag information is avoided, reducing hardware resource consumption. In addition, the creation, management status, MTU (maximum transmission unit), and packet receiving and sending operations of the QinQ interface are completely independent of the VLAN interface, and the MTU of the QinQ interface is independent of the network physical interface, which is convenient for the management and maintenance of the entire system.

[0115] The present invention can simplify the message processing process by removing the dependency between network interfaces, especially in terms of QinQ message information, and search for QinQ interfaces in the self-balancing binary search tree of the network physical interface without going through the VLAN interface. The creation, management status, MTU, and packet receiving and sending operations of the QinQ interface disclosed in the present invention are completely independent of the VLAN interface; the MTU of the QinQ interface is independent of the network physical interface; the QinQ message does not need to be processed by the VLAN message when it is terminated; and the network interfaces are completely independent.

[0116] Furthermore, in this exemplary implementation, a QinQ message processing device 600 is also provided. The QinQ message processing device 600 can be applied to a communication device between a user and a remote end.

[0117] refer to Figure 6 As shown, the vehicle loading rate determination device 600 in the logistics station may include:

[0118] The matching relationship building module 610 is used to determine the matching relationship between the double-layer VLAN tag information and the QinQ interface information; the QinQ interface information includes the QinQ interface identifier.

[0119] The matching relationship configuration module 620 is used to configure the matching relationship in the network physical interface.

[0120] The interface matching module 630 is used to match the double-layer VLAN tag information carried by the QinQ message with the QinQ interface identifier through the network physical interface according to the matching relationship, and determine the QinQ interface identifier corresponding to the QinQ message.

[0121] The message processing module 640 is used to process the QinQ message through the QinQ interface corresponding to the QinQ interface identifier according to the service information.
