Description

TECHNICAL FIELD

[0001] The present application relates to the field of data query, in particular to a data query method, system and computer readable storage medium. BACKGROUND

[0002] In a routing forwarding network, there are various kinds of messages, and it is very difficult for a switch to use hardware logic to process these messages completely. Routing messages can be divided into two categories: protocol messages and data messages. Protocol messages are used for inter-device interaction connection and establishment of related tasks. For a switch, relevant fields in the message need to be parsed and processed according to the protocol. For a single protocol message, a large amount of logic is needed to implement the processing flow. Using hardware to process numerous protocols will make the hardware logic very complex.

For example, a routing table needs to store Internet Protocol Address (IP Address) in a memory for lookup, and also needs to store corresponding forwarding behaviors in the memory for indexing after the IP address is looked up.

[0024] Embodiment 1

[0025] According to an embodiment of the application, an embodiment of a data query system is provided, Figure 1 is a schematic diagram of a data query system according to an embodiment of the application, as Figure 1 shown, comprising message data 102, processing chip 104, processor 106.

[0027] The first index information can be Hash.

[0028] The processing chip can be a hardware processing device, and the processor can be a software processing device.

[0029] Optionally, the processing chip comprises: a first parsing module configured to parse the packet data to obtain a first packet field, and send the first packet field to a first index calculation module, wherein the first packet field is configured to represent a general field of a packet type corresponding to the packet data; the first index calculation module is configured to generate first index information according to the first packet field, and send the first index information to the processor; and a flow module is configured to parse the packet data according to the configuration information to obtain target packet data, and send the target packet data to the processor.

[0030] The first parsing module is configured to parse information contained in the packet data.

[0031] Optionally, the target packet data comprises packet original data and packet annotation data, and the flow module is further configured to parse the packet data according to the configuration information to obtain the packet original data and the packet annotation data, wherein the packet original data is configured to represent data associated with a target task in the packet data, and the packet annotation data is configured to represent annotation data in a packet data forwarding process.

[0032] The packet annotation data is configured to represent annotation data annotated to the packet data by a related device in a packet data forwarding process.

[0033] Optionally, the processor comprises: a second parsing module configured to parse the packet original data to obtain a second packet field, and send the second packet field to a second index calculation module; the second index calculation module is configured to generate second index information according to the second packet field, the packet annotation data and the first index information, and send the second index information to a query module; and the query module is configured to query the second index information based on the preset forwarding table to obtain the forwarding information of the packet data.

[0034] In the embodiment of the present application, the processing chip is configured to generate first index information and target packet data according to received packet data and configuration information, and forward the first index information and the target packet data to the processor; the processor is configured to generate second index information according to the first index information and the target packet data, and query the second index information by using a preset forwarding table to obtain forwarding information of the packet data, wherein the preset forwarding table is configured to record a plurality of index information and forwarding information corresponding to the plurality of index information, and the forwarding information is configured to record information required for forwarding the packet data. The part of the calculation required by the processor can be placed in the processing chip to reduce the calculation resources of the processor, and the efficiency of the query can be improved, thereby solving the technical problem of large resource consumption in the related art for querying the forwarding information.

[0035] Currently, a Hash value is generally calculated by hardware based on IP quintuple and the like, and the Hash value is uploaded to a Central Processing Unit (CPU) for software forwarding lookup table. The specific processing manner is that after the hardware receives an Ethernet packet, the packet field information such as IP quintuple, differentiated services, fragmentation information, layer 2 type, layer 3 type, layer 4 type and the like is parsed. Then, after the packet enters the switch, the packet information such as the entry direction port number, forwarding domain identifier, load sharing information and the like is parsed. According to the task configured on the switch, the corresponding field is selected to calculate a Hash value by using a Cyclic Redundancy Check (CRC) algorithm. The Hash value is uploaded to the CPU. The CPU uses the Hash value to index the forwarding table to find the forwarding information.

[0036] The disadvantage of the above method is that the network has many traffic tasks, different tasks calculate Hash values based on different field information, and the logic implemented by hardware is relatively complex. Moreover, the hardware fixed logic cannot finely divide and select the field information, and lacks flexibility.

[0037] Currently, there is another method for calculating a Hash value by software based on IP quintuple and the like for software forwarding lookup table. Specifically, the hardware uploads the packet and the related packet information after the packet enters the switch to the CPU. The CPU parses the packet field information, selects the field in combination with the task, calculates a Hash value by using the CRC to index the forwarding table, and finds the forwarding information.

[0038] The disadvantage of the above method is that the Hash value is completely calculated by software, which occupies the CPU resources, and the performance is much lower than that of hardware, thereby increasing the packet forwarding delay.

[0039] In view of the above method in flexibility and performance has some shortcomings, the present application proposes a combination of software and hardware Hash computing method, which can provide more accurate and fast soft forwarding. The basic idea of the present application is that the long field normalization field is calculated in hardware, and the optional implementation of the field set is realized. The software combines the calculation results of the hardware, and further performs incremental calculation on the additional fields required by different task stages.

[0040] The CPU needs to calculate an index value to find the soft forwarding table. In order to distinguish different tasks and different forwarding behaviors, the index value needs to be related to the characteristic message field of the task and the related forwarding information. That is, the index value is calculated by combining the characteristic message field and the related forwarding information. The calculation of this index value usually uses CRC calculation. A good polynomial is selected, and a long template composed of the characteristic message field and the related forwarding information is calculated to obtain a short Hash value. This Hash value is the index value.

[0041] In order to improve performance, part of the calculation in the original CPU is offloaded to the hardware in the present application. Figure 2 is a schematic diagram of another data query system according to an embodiment of the present application, as shown in Figure 2 The processing of the message data can be divided into two parts, chip processing and CPU processing. After the message data enters the switch, the chip is parsed by the first parsing module. Based on the message three-layer type, four-layer type, and whether it is a tunnel message, the field information parsing result (ParserResult) in the message is obtained.

[0042] In other module processes, such as the above-mentioned process module, the switch will analyze according to the current configuration whether the message data belongs to a task and whether it needs to use soft forwarding, collect the forwarding information (PacketInfo) of the message in the switch, that is, obtain the above-mentioned message original data and message labeled data.

[0043] Part of the calculation in the CPU is offloaded to the Hash calculation module of the chip. Mainly to calculate the long field normalization field in the routing task, that is, to calculate the optional configuration. For example, the IP five tuple is a general field in the routing message. For IPv4 messages, the five tuple has the source IP address (IPDA) + the destination IP address (IPSA) + the source port number (Protocol) + the destination port number (L4SrcPort) + the protocol number (L4DstPort), a total of 104 bits. And the IPv6 message has 296 bits. In the Hash calculation module, the parsed five tuple information is taken out from the ParserResult, and a 32-bit Hash value is calculated through CRC. The Hash value is sent to the CPU through the PacketHeader to replace the IP five tuple used when calculating the Hash value in software forwarding. It should be noted that for tunnel messages, the outer Hash and the inner Hash need to be calculated, and the CPU determines which one to use for calculation.

[0044] The chip will send the message data that needs to be soft forwarded and the required PacketInfo (message annotation data) to the CPU through the PacketHeader for software processing.

[0045] After the CPU receives the message data, the second parsing module of the CPU parses the original message data to obtain the second message field, for example, the information outside the five tuple such as the fragmentation information, the service type, etc., and transmits the second message field to the second index calculation module of the CPU.

[0046] The Hash calculation module of the CPU obtains the first index information (HashValue) calculated by the chip and the message annotation data (PacketInfo) used to distinguish tasks from the PacketHeader. According to different tasks, the fields parsed by the CPU parsing module (i.e., the second message field described above) are selected to combine the second message field and then do CRC calculation to obtain the second index information of the soft forwarding table.

[0047] In the lookup module of the CPU, the preset forwarding table corresponding to the configuration / learning is found from the Memory according to the second index information, so as to obtain the forwarding information according to the preset forwarding table. According to the forwarding information, the message editing mode and the forwarding outlet can be known. Then it is sent to the chip and forwarded out.

[0048] Through the above content of the present application, the software lookup Hash value is realized by the optional implementation of the field set to calculate the long field normalization field in hardware. The software combines the calculation results of hardware, and further performs incremental calculation on the additional fields required by different business stages. The software directly uses the final result to query the Hash table.
