Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a network data processing method, device, network equipment and storage medium. Background Art

[0002] Link aggregation technology can achieve the purpose of increasing link bandwidth by bundling multiple physical interfaces into one logical interface without hardware upgrade. While achieving the purpose of increasing bandwidth, link aggregation adopts the mechanism of backup link, which can effectively improve the reliability of links between devices. After the network device creates an aggregation group, the aggregation group can be configured as a three-layer aggregation group or a two-layer aggregation group. The three-layer aggregation interface can be configured with an IP address to guide the completion of routing and forwarding functions.

[0003] Network devices can create aggregation groups based on the Data Plane Development Kit (DPDK). After adding physical interfaces to the aggregation group, they can send and receive messages to the outside in the form of the aggregation group. All member interfaces and aggregation interfaces use the same interface MAC address. When processing forwarding services, they only need to complete three-layer forwarding based on the IP address configured for the aggregation interface and the routing table of the network device. When the member interface switches state and a member interface is physically DOWN, the entire aggregation group can still work. However, when other member interfaces receive messages to access the network device itself, if the messages need to be sent to the kernel network card corresponding to the member interface that is physically DOWN, the messages will be discarded, affecting the processing of the messages.

[0004] In order to solve the above technical problems, two technical solutions are provided in the related art. One is to bypass the kernel network card and use some open source protocol stacks to process the messages that need to be processed by the network device itself. However, the architecture of the open source protocol stack is complex. The other is to modify the MAC address information of the message and send the modified message to the kernel network card corresponding to the aggregation interface matching the modified MAC address information. However, this method requires multiple unpacking, assembly and modification of the message, which seriously affects the processing efficiency of the message. Summary of the invention

[0005] The present invention provides a network data processing method, apparatus, network equipment and storage medium to solve the technical problem of how to improve the processing efficiency of network equipment for network data that needs to be processed by itself while ensuring that the network data is not discarded when a member interface configured with an aggregate interface IP address is in an inactive state.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0029] Figure 1 A flowchart of a network data processing method is provided for the first embodiment of the present invention. This embodiment is applicable to the case of processing network data. The method can be executed by a network data processing device. The network data processing device can be implemented in the form of hardware and / or software. The network data processing device can be configured in a network device. Figure 1 As shown, the method includes:

[0030] S110. When receiving network data, determine the data type of the network data; wherein the data type includes routing network data and non-routing network data.

[0031] Among them, network equipment is a dedicated hardware device used to connect various servers, PCs, application terminals and other nodes to form an information communication network. Network equipment can include switches, routers, firewalls, bridges, hubs, gateways, VPN servers, network interface cards, wireless access points, modems, 5G base stations, optical terminals, optical transceivers, optical cables, etc.

[0032] In an embodiment of the present invention, a network device receives network data sent by other network devices in real time, wherein the network data may be a network data packet, for example, the network data is a data message. The received network data is analyzed to determine the quantity and type of the network data. The data types include routing network data and non-routing network data, wherein routing network data refers to network data that needs to be forwarded to other devices, and non-routing network data refers to network data that needs to be processed by the network device itself. Exemplarily, the network data includes a data type identifier, and the data type of the network data is determined according to the data type identifier. It should be noted that the embodiment of the present invention does not limit the method for determining the data type of the network data.

[0033] S120. When the network data is non-routing network data, determine the physical state of the first member interface in the aggregate interface of the network device; wherein the physical state includes an active state and an inactive state; and the first member interface is a member interface configured with an aggregate interface IP address.

[0034] In an embodiment of the present invention, the DPDK in the network device provides a kernel NIC interface (KNI) and a Bond interface. Among them, the communication between the DPDK application and the kernel can be realized through the KNI interface, that is, the message can be sent to the kernel protocol stack for processing through the KNI interface. The Bond interface can be understood as an aggregated interface after aggregating and binding multiple network interfaces. Using DPDK, an aggregation group is created, and the physical interface is added to the aggregation group. The member interfaces under the aggregation group can send and receive messages. When the aggregation group performs three-layer forwarding, the IP address is configured on the aggregation interface, and while configuring the IP address for the aggregation interface, the same IP address is configured for any member interface of the aggregation interface to guide the aggregation group to perform three-layer forwarding. When the aggregation group is created, the MAC address of the member interface configured with the IP address is used as the MAC address of the aggregation port. Optionally, the network device can create one or more aggregation groups through DPDK, so there are one or more corresponding aggregation interfaces.

[0035] Optionally, determining the type of the network data includes: parsing the network data to determine the target IP address of the network data; when the target IP address is consistent with the aggregate interface IP address, determining that the network data is non-routing network data; when the target IP address is inconsistent with the aggregate interface IP address, determining that the network data is routing network data. Specifically, the network data is parsed to determine the IP address in the network data, and the IP address parsed from the network data is referred to as the target IP address. Among all the aggregate interfaces of the network device, the aggregate interface whose MAC address is the same as the MAC address parsed from the network data is searched as the target aggregate interface. Then, the aggregate interface IP address of the target aggregate interface is further obtained, wherein the aggregate interface IP address is the IP address pre-configured on the target aggregate interface. Determine whether the target IP address parsed from the network data is consistent with the aggregate interface IP address. If so, it means that the network data is non-routing network data, that is, the network device itself needs to process the network data. Otherwise, it is determined that the network data is routing network data, that is, the network data is network data to be forwarded, and the network device needs to forward the network data to other devices without the network device processing the network data.

[0036] When it is determined that the network data is non-routing network data, the first member interface configured with the aggregate interface IP address is determined from each member interface of the aggregate interface, and the physical state of the first member interface is determined, wherein the physical state includes an active state (also referred to as an UP state) and an inactive state (also referred to as a DOWN state). The active state can be understood as the interface being in a working state and being able to send and receive data normally, and the inactive state can be understood as the interface being in a fault state or a backup state and being unable to send and receive data normally.

[0037] S130. When the first member interface is in an inactive state, the network data is sent to the kernel network card corresponding to the second member interface through the aggregation interface, so that the kernel network card corresponding to the second member interface processes the network data; wherein, the second member interface is any member interface in the aggregation interface that is in an active state.

[0038] In an embodiment of the present invention, when the first member interface is in an inactive state, a target member interface whose physical state is active is searched from all member interfaces of the aggregated interface, and a second member interface is determined from the target member interfaces whose physical state is active. Among them, a member interface can be randomly selected from the target member interfaces as the second member interface, or a member interface can be determined from the target member interfaces as the second member interface according to a preset rule. Then, the network device sends the network data to the kernel network card corresponding to the second member interface through the aggregated interface, so that the kernel network card corresponding to the second member interface processes the network data. For example, the network data can be processed based on the kernel protocol stack on the kernel network card corresponding to the second member interface.

[0039] Optionally, when the first member interface is in an inactive state, the network data is sent to the kernel network card corresponding to the second member interface through the aggregation interface, including: when the first member interface is in an inactive state, migrating the aggregation interface IP address to the second member interface in the aggregation interface, and updating the initial physical address of the aggregation interface based on the target physical address of the kernel network card corresponding to the second member interface; sending the network data to the kernel network card corresponding to the second member interface through the aggregation interface.

[0040] Exemplarily, when the first member interface is inactive, the aggregate interface IP address (i.e., the IP address configured by the aggregate interface) is migrated to the second member interface. It is understandable that the aggregate interface IP address is reconfigured on the second member interface, and the target physical address (i.e., the target MAC address) of the kernel network card corresponding to the second member interface is obtained, and then the initial physical address of the aggregate interface is updated based on the target physical address. It is understandable that the initial physical address of the aggregate interface is changed from the initial physical address to the target physical address. In an embodiment of the present invention, the configured MAC addresses of all member interfaces of the aggregate interface can also be updated to the target physical address. Then, the network data is sent to the kernel network card corresponding to the second member interface through the aggregate interface.

[0041] Optionally, after updating the initial physical address of the aggregate interface based on the target physical address of the kernel network card corresponding to the second member interface, it also includes: generating a physical address update message, and sending the physical address update message to the opposite network device; wherein the physical address update information is used to instruct the opposite network device to update a pre-stored Address Resolution Protocol (ARP) table based on the target physical address, the ARP table being a correspondence table between the physical address of the aggregate interface and the IP address, and the opposite network device is a network device used to send the network data.

[0042] Exemplarily, after updating the initial physical address of the aggregate interface based on the target physical address of the kernel network card corresponding to the second member interface, a physical address update message is generated, for example, the physical address update message can be an ARP message, and the ARP message is sent to the peer network device. The peer network device is a network device for sending network data. The peer network device updates a pre-stored ARP table based on the ARP message, wherein the ARP table is a correspondence table between the physical address of the aggregate interface and the IP address. It can be understood that the initial physical address of the aggregate interface in the ARP table is updated to the target physical address corresponding to the second member. The advantage of such a setting is that the peer network device can be instructed to send subsequent network data to be processed based on the updated ARP table.

[0043] The network data processing method of the embodiment of the present invention, when receiving network data, determines the data type of the network data; wherein the data type includes routing network data and non-routing network data; when the network data is non-routing network data, determines the physical state of the first member interface in the aggregation interface of the network device; wherein the physical state includes active state and inactive state; the first member interface is a member interface configured with the aggregation interface IP address; when the first member interface is inactive, the network data is sent to the kernel network card corresponding to the second member interface through the aggregation interface, so that the kernel network card corresponding to the second member interface processes the network data; wherein the second member interface is any member interface in the aggregation interface that is in active state. The technical solution provided by the embodiment of the present invention solves the technical problem that the network data is discarded when the member interface configured with the aggregation interface IP address is inactive, not only does it not need to develop an open source protocol stack with a complex architecture, but it also does not need to modify the received network data, nor does it need to rebind the aggregation group, avoiding the phenomenon of interface physical state switching during re-aggregation, which can greatly improve the processing efficiency of the network device for the network data that it needs to process.

[0044] In some embodiments, it also includes: when the network data is routing network data, obtaining a pre-stored routing table; wherein the routing table is a correspondence table between IP addresses and network devices; based on the routing table, searching for a target device whose IP address is consistent with the target IP address of the network data, and forwarding the network data to the target device. Exemplarily, when the target IP address parsed from the network data is inconsistent with the aggregate interface IP address, it is determined that the network data is routing network data. At this time, obtaining a pre-stored routing table in the network device, wherein the routing table is a correspondence table between IP addresses and network devices. Searching for a target device whose IP address is consistent with the target IP address in the routing table, and then the network device forwards the network data to the target device. For example, the network data can be forwarded to the target device via an aggregate interface.

[0045] In some embodiments, it also includes: when the first member interface is in an active state, the network data is sent to the kernel network card corresponding to the first member interface through the aggregation interface, so that the kernel network card corresponding to the first member processes the network data. Exemplarily, when the first member interface is in an active state, it means that the kernel network card corresponding to the first member interface will not discard the network data. At this time, the network data is sent to the kernel network card corresponding to the first member interface through the aggregation interface, so that the kernel network card corresponding to the first member interface processes the network data. For example, the network data can be processed based on the kernel protocol stack on the kernel network card corresponding to the first member interface.

[0046] In some embodiments, after sending the network data to the kernel network card corresponding to the second member interface through the aggregation interface so that the kernel network card corresponding to the second member interface processes the network data, it also includes: the kernel network card corresponding to the second member interface sends response data to the opposite network device; wherein the response data includes the target physical address of the kernel network card corresponding to the second member interface, and the opposite network device is a network device for sending the network data. Exemplarily, after the kernel network card corresponding to the second member interface processes the network data, it generates response data for the network data based on the processing result, and feeds back the response data to the opposite network device. wherein the response data includes the target physical address of the kernel network card corresponding to the second member interface.

[0047] Embodiment 2

[0048] Figure 2 A flowchart of a network data processing method provided in Embodiment 2 of the present invention is shown in FIG. Figure 2 As shown, the method includes:

[0049] S210. When network data is received, the network data is parsed to determine a target IP address and a target MAC address of the network data.

[0050] S220. Determine a target aggregate interface according to the target MAC address, and obtain an aggregate interface IP address of the target aggregate interface, wherein the target aggregate interface is an aggregate interface with a pre-configured MAC address that is the same as that of the target aggregate interface.

[0051] S230. Determine whether the target IP address is consistent with the aggregate interface IP address. If so, execute S240; otherwise, execute S2100.

[0052] S240, determining whether the physical state of the first member interface in the target aggregate interface is active, if so, executing S290, otherwise, executing S250.

[0053] The physical state includes an active state and an inactive state, and the first member interface is a member interface configured with an aggregate interface IP address.

[0054] S250: Migrate the aggregate interface IP address to the second member interface in the target aggregate interface, and update the initial physical address of the target aggregate interface based on the target physical address of the kernel network card corresponding to the second member interface.

[0055] S260. Send the network data to the kernel network card corresponding to the second member interface through the target aggregation interface, so that the kernel network card corresponding to the second member processes the network data.

[0056] S270. The kernel network card corresponding to the second member interface sends response data to the opposite network device; wherein the response data includes the target physical address of the kernel network card corresponding to the second member interface, and the opposite network device is a network device used to send the network data.

[0057] S280. Generate a physical address update message, and send the physical address update message to the peer network device; wherein the physical address update information is used to instruct the peer network device to update a pre-stored Address Resolution Protocol ARP table based on the target physical address, the ARP table is a correspondence table between the physical address and the IP address of the aggregation interface, and the peer network device is a network device used to send the network data.

[0058] S290. Send the network data to the kernel network card corresponding to the first member interface through the target aggregation interface, so that the kernel network card corresponding to the first member processes the network data.

[0059] S2100. Obtain a pre-stored routing table; wherein the routing table is a correspondence table between IP addresses and network devices.

[0060] S2110. Search for a target device whose IP address is consistent with the target IP address based on the routing table, and forward the network data to the target device.

[0061] For example, Figure 3 A system architecture diagram based on DPDK provided in an embodiment of the present invention. Figure 3 As shown in the figure, the Bond interface provided by DPDK isolates the aggregation interface corresponding to the aggregation group from the underlying physical interface by creating an aggregation group, and unbinds the driver layer of the underlying kernel network card and the upper network layer (also called the business layer).

[0062] Taking the physical interfaces PORT1, PORT2, and PORT3 as examples, when these three physical interfaces are used as independent service interfaces, IP can be configured separately and three-layer forwarding can be completed. These three physical interfaces have different MAC addresses, and when receiving messages to be forwarded or sent to the KNI interface, they can all be processed normally. Table 1 is a configuration information table before physical interface aggregation provided by an embodiment of the present invention:

[0063] Table 1 Configuration information before physical interface aggregation

[0064]

[0065] After creating an aggregation group based on DPDK, the physical interfaces PORT1, PORT2, and PORT3 are aggregated to generate an aggregation interface TRUNK, and the IP address configured for the aggregation interface TRUNK is configured on the kernel network card corresponding to the member interface PORT1. At the same time, the MAC address of the kernel network card corresponding to the member interface PORT1 is used as the MAC address of the entire aggregation group, and the MAC address of each member interface under the aggregation group is updated based on the MAC address of the aggregation group configured by DPDK. At the business level, each member interface uses the same interface MAC address and appears to be the same interface to the outside world. Table 2 is a physical interface aggregation configuration information table provided in an embodiment of the present invention:

[0066] Table 2 Physical interface aggregation configuration information

[0067]

[0068]

[0069] When the physical interface under the aggregation group receives a message, if the destination IP address of the message is inconsistent with the IP address of the aggregation interface, a route search is performed, for example, a target device whose IP address is consistent with the destination IP address of the message is searched according to the pre-stored routing table, and the message is forwarded to the target device. If the destination IP address of the message is consistent with the IP address of the aggregation interface, the message is sent through the aggregation interface to the kernel network card corresponding to the member interface configured with the IP address of the aggregation interface, and the kernel network card processes the message.

[0070] For example, when member interfaces PORT1, PORT2, and PORT3 receive a message with a target IP address of 10.2.1.1, they all determine that the message is an address message for accessing themselves. The message is sent to the kernel network card corresponding to member interface PORT1 for processing. After the kernel network card corresponding to member interface PORT1 completes processing of the message, if a response message needs to be sent, a response message is generated and sent to the peer network device through the kernel network card corresponding to member interface PORT1, wherein the source MAC address of the response message uses the MAC address of the kernel network card corresponding to member interface PORT1.

[0071] When member interface PORT1 is DOWN for some reason, and the network device detects that the physical state of member interface PORT1 is in the DOWN state, since member interface PORT1 is a physical interface configured with the aggregate interface IP address, at this time, the IP address configured on the member interface PORT1 (that is, the aggregate interface IP address) is migrated. Specifically, the aggregate interface IP address is reconfigured on a network card that can work normally.

[0072] Exemplarily, when the physical state of the member interface PORT2 is detected to be UP (i.e., active state, also referred to as normal state), the IP address of the aggregation interface is reconfigured on the member interface PORT2. After the IP address migration is successful, the MAC address of the kernel network card corresponding to the member interface PORT2 is obtained, and the MAC address of the aggregation interface TRUNK is updated to the MAC address of the kernel network card corresponding to the member interface PORT2. Table 3 is a configuration information table after the physical interface address information is updated according to an embodiment of the present invention:

[0073] Table 3 Configuration information table after physical interface address information is updated

[0074]

[0075] The local network device sends an ARP message to the peer network device, so that the peer network device updates the pre-stored ARP according to the received ARP message. Specifically, the peer network device updates the MAC address of the aggregation interface in the ARP table to 6C:F1:7E:9C:00:C8 based on the ARP message. When the peer network device subsequently sends other messages that need to be processed by the local network device itself (that is, non-routing messages) to the local network device, they are all sent to the kernel network card corresponding to member PORT2.
