[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0029] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in one or more embodiments of this specification are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and corresponding operation entrances shall be provided for users to choose to authorize or refuse.

[0030] With the development of Internet technology, users can send data requests to servers through terminals. When the server receives the data request, it responds to the data request and feeds back the corresponding data packet to the terminal.

[0031] In the related technology, the server can feed back the data packet to the terminal through the data plane. Among them, the data plane uses fixed functions to forward data packets based on some protocols. This closed design mode uses hard coding to limit the switch to proprietary function implementation, and the development cycle is lengthy and inflexible. Currently, P4 (Programming Protocol-independent Packet Processors) switches are widely used in the modern network field based on SDN (Software Defined Networking) due to their excellent performance in development flexibility due to their programmability.

[0032] Among them, the P4 switch has the concept of pipeline when processing messages. A pipeline represents a complete set of message processing procedures. This concept is similar to the pipeline in traditional switches. Figure 1 As shown in the figure, the message processing flow includes: standard Ingress (entry processing flow) processing, three business logic tables Table1 / 2 / 3 processing and standard Egress (egress processing flow) processing. For the convenience of understanding, this message processing flow will also be used in the future. Among them, the three business logic tables Table1 / 2 / 3 are configured in a P4 switch.

[0033] The inventors have discovered that there are at least the following technical problems in the related art: Due to the cost of hardware chips, the underlying resources of P4 switches are often very scarce. As a result, the processing capacity of P4 switches is limited by the scarcity of underlying resources, which in turn limits the scale of users that can be served by P4 switches.

[0034] In response to the technical problems in the prior art, the inventor's technical conception is as follows: by connecting multiple P4 switches in series, multiple business logic tables (such as the above-mentioned three business logic tables Table1 / 2 / 3) are configured in multiple P4 switches, and a complete message processing flow is formed by multiple P4 switches, thereby achieving the purpose of table item expansion.

[0035] Accordingly, the specific steps may include: first, in response to receiving a data packet sent by a client, obtaining the pipeline information corresponding to the data packet; the pipeline information includes multiple business logic tables and the business processing order of the multiple business logic tables; wherein the multiple business logic tables are configured to multiple network forwarding devices in a series relationship after capacity expansion, and the multiple network forwarding devices are connected in sequence according to the business processing order of the multiple business logic tables. Secondly, forwarding the data packet to the first network forwarding device among the multiple network forwarding devices, processing the data packet through the business logic table configured in the first network forwarding device, and forwarding the processed data packet to the next network forwarding device according to the connection order of the multiple network forwarding devices, until the last network forwarding device.

[0036] In this technical solution, since multiple business logic tables are configured in multiple network forwarding devices in a series relationship after capacity expansion, data packets can be processed based on the device capabilities of multiple network forwarding devices through the business logic tables after capacity expansion. Therefore, while improving the efficiency of data packet processing, it can also meet the resource needs of users of various sizes.

[0037] The following is a specific implementation process of the cloud network-based data transmission method and device involved in the embodiments of the present disclosure. Some examples are for illustrative purposes only and are not intended to be limiting. The execution subject of the cloud network-based data transmission method involved in the embodiments of the present disclosure is an electronic device, which may be a terminal, a server, etc.

[0038] Figure 2 The process of the data transmission method based on the cloud network provided by the embodiment of the present disclosure Figure 1 ,like Figure 2 As shown, the cloud network-based data transmission method may include:

[0039] S201. In response to receiving a data packet sent by a client, pipeline information corresponding to the data packet is obtained; the pipeline information includes multiple business logic tables and a business processing order of the multiple business logic tables; wherein the multiple business logic tables are configured to multiple network forwarding devices in a series relationship after capacity expansion, and the multiple network forwarding devices are connected in sequence according to the business processing order of the multiple business logic tables.

[0040] In the embodiment of the present disclosure, the network forwarding device may be any type of network device for forwarding or processing data packets. Optionally, the network forwarding device may be a gateway device, a P4 switch, and the like.

[0041] In one embodiment, multiple network forwarding devices can be connected in series by means of a protocol combination. The corresponding specific steps may include: determining the connection order of multiple network forwarding devices configured with multiple business logic tables according to the business processing order of multiple business logic tables; determining two adjacent network forwarding devices among the multiple network forwarding devices according to the connection order of the multiple network forwarding devices; and connecting the data packet sending end and the data packet receiving end of the two adjacent network forwarding devices in series through a preset transmission protocol. Among them, in actual applications, the multiple network forwarding devices in series relationship may only connect two network forwarding devices in series, or may connect multiple network forwarding devices in series.

[0042] Each network forwarding device includes a standard Ingress (entry processing flow) and a standard Egress (exit processing flow). In this application, in order to improve the transmission efficiency of data packets, the standard transmission protocol can be replaced by a preset transmission protocol. At the same time, the standard Ingress (entry processing flow) and the standard Egress (exit processing flow) in the network forwarding device need to be adjusted to adapt to the above-mentioned preset transmission protocol.

[0043] Optionally, the data packet sending end and the data packet receiving end of two adjacent network forwarding devices are connected in series through a preset transmission protocol, including: modifying the first egress processing flow and the first ingress processing flow of the two adjacent network forwarding devices into a second egress processing flow and a second ingress processing flow that comply with the preset transmission protocol; wherein the second egress processing flow and the second ingress processing flow that comply with the preset transmission protocol are used to transmit the processing result information of the network forwarding device.

[0044] Exemplarily, the first egress processing flow is a standard Egress (egress processing flow), and the first ingress processing flow is a standard Ingress (ingress processing flow). For two adjacent network forwarding devices, the standard egress processing flow of the first network forwarding device of the two adjacent network forwarding devices is modified to an egress processing flow that complies with a preset transmission protocol, and the standard ingress processing flow of the second network forwarding device is modified to an ingress processing flow that complies with a preset transmission protocol.

[0045] Among them, the egress processing flow that complies with the preset transmission protocol is used to add the processing result information of the network forwarding device on the data packet to the packet header according to the preset transmission protocol when the network forwarding device sends the data packet, and configure the destination port in the packet header as the data packet receiving end of the next network forwarding device. Among them, the ingress processing flow that complies with the preset transmission protocol is used to parse the packet header of the data packet when the network forwarding device receives the data packet, and obtain the processing result information of the previous network forwarding device on the data packet.

[0046] Optionally, the preset transmission protocol may be a Geneve (Generic Network Virtualization Encapsulation) transmission protocol.

[0047] For example, Figure 3 As shown, the packet header includes the header information of UDP (user datagram protocol) and the header information of Geneve transmission protocol. If the packet receiving end of the next network forwarding device is: 6081Geneve, the destination port in the UDP header information in the packet header is configured as: 6081Geneve.

[0048] Furthermore, in the header information of the Geneve transport protocol,

[0049] Ver means: the current version number is 0

[0050] Opt Len indicates the length of the Variable-Length Options part, in 4-byte units, with a maximum of 256 bytes.

[0051] O flag: Control message flag. When set, the receiving end does not forward the message.

[0052] C flag: When set, it indicates that there are one or more critical options. The tunnel endpoint must parse the Options part; if it cannot be parsed, it is discarded.

[0053] Protocol Type indicates: the protocol type of the inner data packet.

[0054] Virtual Network Identifier (VNI) means: a unique virtual network identifier.

[0055] Variable-Length Options means: an option set in TLV format, which is also a field carried by the communication protocol of the present invention.

[0056] In an embodiment of the present disclosure, in response to receiving a data packet sent by a client, before obtaining pipeline information corresponding to the data packet, the method also includes: expanding the capacity of each business logic table according to a preset expansion multiple corresponding to each business logic table; configuring the multiple business logic tables after capacity expansion to multiple network forwarding devices in sequence according to the business processing order of the multiple business logic tables; wherein the expansion multiple of the total capacity of the multiple business logic tables matches the number of the multiple network forwarding devices.

[0057] Optionally, the expansion multiple of the total capacity of the multiple business logic tables matches the number of the multiple network forwarding devices, which means that the number of the multiple network forwarding devices is the same as the expansion multiple of the total capacity of the multiple business logic tables.

[0058] The preset expansion multiples corresponding to the various business logic tables may be the same or different.

[0059] In some embodiments, the preset expansion multiples corresponding to each business logic table may be the same. Figure 4 As shown, the number of multiple network forwarding devices is 2, and the preset expansion multiples corresponding to the business logic tables are all 2. The multiple business logic tables include: Table1, Table2, and Table3. The business processing order of Table1, Table2, and Table3 is: Table1→Table2→Table3. According to the business processing order of the multiple business logic tables, the multiple business logic tables Table1, Table2, and Table3 after capacity expansion are sequentially configured to the two network forwarding devices.

[0060] It should be noted that in some scenarios, since capacity cannot be expanded on a single device, it is necessary to split a business logic table into two and configure them to two network forwarding devices respectively. Figure 3 As shown, the business logic table Table2 can be split into two and configured to two network forwarding devices respectively.

[0061] In other embodiments, not all business logic tables have capacity problems, so the capacity of only some business logic tables may be expanded.

[0062] Optionally, the business logic table includes an operation and maintenance table and a business table; the preset expansion multiple of the operation and maintenance table is equal to 1, and the preset expansion multiple of the business table is greater than 1. Accordingly, configuring multiple business logic tables to multiple network forwarding devices may include: keeping the capacity of the operation and maintenance table in the multiple business logic tables unchanged, expanding the capacity of the business table in the multiple business logic tables to a preset multiple; configuring the operation and maintenance table and each expanded business table to the multiple network forwarding devices in sequence according to the business processing order of the operation and maintenance table and each business table.

[0063] For example, Figure 5 As shown in the figure, the forwarding processing logic includes three business logic tables: Table 1, Table 2, and Table 3. Among them, Table 1 is the operation and maintenance table, and Table 2 and Table 3 are business tables. If the capacity of all three tables is doubled, Table 1 will waste some resources. If according to the above logic, Table 1 resources remain unchanged, and the extra resources are allocated to Table 2, then Table 2 can be expanded to 3 times the original size, achieving the purpose of fully utilizing resources.

[0064] S202, forwarding the data packet to the first network forwarding device among multiple network forwarding devices, processing the data packet through the business logic table configured in the first network forwarding device, and forwarding the processed data packet to the next network forwarding device according to the connection order of the multiple network forwarding devices, until the last network forwarding device.

[0065] In the embodiment of the present disclosure, a data packet is processed by a service logic table configured in a first network forwarding device, and the processed data packet is forwarded to the next network forwarding device according to the connection order of multiple network forwarding devices, until the last network forwarding device, including the following steps (1) to (4):

[0066] (1) Query the forwarding rule information corresponding to the data packet from the service logic table configured in the first network forwarding device to obtain the first query result of the data packet.

[0067] (2) When the first network forwarding device sends a data packet, the first query result of the first network forwarding device on the data packet is added to the packet header of the data packet according to the preset transmission protocol, and the destination port in the packet header is configured as the data packet receiving end of the next network forwarding device according to the connection order of the multiple network forwarding devices.

[0068] Optionally, the first query result of the first network forwarding device on the data packet is added to the header of the data packet according to the preset transmission protocol, including: if the forwarding rule information corresponding to the data packet is hit from the business logic table configured by the first network forwarding device, the forwarding rule information is added to the header of the data packet according to the preset transmission protocol.

[0069] Optionally, the forwarding rule information includes a business logic table identifier, a rule length, and a rule content. Accordingly, adding the forwarding rule information to the header of the data packet according to the preset transmission protocol includes: configuring a first preset field in the header of the data packet according to the business logic table identifier, configuring a second preset field in the header of the data packet according to the rule length, and configuring a third preset field in the header of the data packet according to the rule content.

[0070] It should be noted that if the forwarding rule corresponding to the data packet is not hit in the business logic table configured from the first network forwarding device, the business logic table identifier of the business logic table is determined; according to the business logic table identifier, the first preset field in the packet header of the data packet is configured, and the second preset field and the third preset field in the packet header are kept unchanged.

[0071] For example, the header of a data packet is as follows: Figure 6 As shown, where:

[0072] Option Class means: option category, used to identify usage scenarios.

[0073] Type indicates: the option type under the namespace, which determines the meaning and format of the Data part. If the first bit is set, it indicates that this option is a critical option and must be parsed by the tunnel endpoint. If a critical option exists, the C flag in the header information of the above Geneve transport protocol also needs to be set at the same time.

[0074] Length means: Option Data length in 4-byte units, which is also the rule length.

[0075] Variable-Length Options Data means: the option content defined by Type, used to store the rule content.

[0076] (3) Until the last network forwarding device receives the data packet, the packet header is parsed to obtain the first query result of the data packet by the previous network forwarding devices, and the forwarding rule information corresponding to the data packet is queried from the business logic table configured by the last network forwarding device to obtain the second query result of the data packet.

[0077] For example, Figure 7As shown, the first query result and the second query result of each network forwarding device for the data packet include: Table 1 query result, Table 2 query result and Table 3 query result. Among them, Class is 0x158, which means the usage scenario is switch series connection. Data is the query result of the corresponding table item, which defaults to 0. If it is not hit, the default value is retained.

[0078] (4) Forwarding the data packet according to the forwarding rules in the first query results and the forwarding rules in the second query results.

[0079] The disclosed embodiment provides a data transmission method based on a cloud network: first, in response to receiving a data packet sent by a client, the pipeline information corresponding to the data packet is obtained; the pipeline information includes multiple business logic tables and the business processing order of the multiple business logic tables; wherein the multiple business logic tables are configured to multiple network forwarding devices in a series relationship after capacity expansion, and the multiple network forwarding devices are connected in sequence according to the business processing order of the multiple business logic tables. Secondly, the data packet is forwarded to the first network forwarding device among the multiple network forwarding devices, the data packet is processed by the business logic table configured in the first network forwarding device, and the processed data packet is forwarded to the next network forwarding device according to the connection order of the multiple network forwarding devices, until the last network forwarding device. In this technical solution, since the multiple business logic tables are configured to multiple network forwarding devices in a series relationship after capacity expansion, the data packet can be processed based on the device capabilities of the multiple network forwarding devices through the business logic table after capacity expansion, so that while improving the efficiency of data packet processing, it can also meet the resource needs of users of various sizes.
