The method and the device are applied to a service scene based on a cloud technology, wherein the cloud technology refers to a hosting technology for integrating hardware, software, network and other series resources in a wide area network or a local area network to realize calculation, storage, processing and sharing of data. The embodiment of the application can be applied to various scenes of data forwarding (or data exchange) combined with cloud technology, such as devices adopting servers, switches, routers and the like, and network components for data forwarding, so that the application can be applied to various scenes related to data forwarding, such as data migration, access, query and the like. For ease of description, various devices in the data forwarding end that perform data forwarding, as well as network components, are referred to as data forwarding devices.
The embodiment of the application discloses a data forwarding system, as shown in fig. 1A, the system includes: the first end is used for accessing, inquiring and data migration to the second end. The second end is used for returning feedback information to the first end according to the access and the inquiry of the first end and storing the migrated data. The data forwarding device may include various devices such as a server (cluster), a switch, a router, and a network component. The embodiment of the application can be applied to various devices for forwarding and interacting data at a data forwarding end.
The data forwarding device includes: a central processing unit (Central Processing Unit, CPU), a first programmable component and a second programmable component. The CPU is the operation and control core of the system and is the final execution unit for information processing and program running. The first programmable component and the second programmable component are used for forwarding data of different characteristics. According to the embodiment of the application, different types of data are forwarded through different types of programmable components, so that the data forwarding capacity of the data forwarding device is improved, and the forwarding efficiency of target data is improved.
The first programmable component is used for forwarding target data meeting a first condition, and the second programmable component is used for forwarding target data meeting a second condition. Specifically, after receiving the target data transmitted by the first end, the data forwarding device may detect feature information of the target data, divide the target data into data meeting a first condition and data meeting a second condition according to the feature information of the target data, and forward the divided target data by adopting a corresponding programmable component. By adopting the corresponding programmable components to forward data, the data forwarding efficiency can be improved.
The first storage table corresponding to the first programmable component may be set in the data forwarding device, the first storage table stores feature information of data meeting the first condition, and when the target data is divided, the feature information of the target data may be matched with the feature information stored in the first storage table. In one example of data processing, as shown in FIG. 1B:
after receiving the target data, the data forwarding device detects, in step 102, characteristic information of the target data, and then matches the characteristic information of the target data with the first storage table. Under the condition that the characteristic information of the target data is matched with the first storage table, determining that the characteristic information of the target data accords with a first condition; and under the condition that the characteristic information of the target data is not matched with the first storage table, determining that the characteristic information of the target data meets a second condition. In addition, a second storage table corresponding to the second programmable component may be set in the data forwarding device, where feature information of the data meeting the second condition is stored in the second storage table. The characteristic information of the target data may also be matched with the second memory table.
In an alternative embodiment, in setting the first storage table and the second storage table, the target data may be classified according to characteristics of the data in terms of traffic, such as size of the traffic and rate of the traffic. Data for a large number of continuous transmissions in the network (e.g., data for data migration) may be stored in the first memory table as data that meets the first condition. Data (e.g., mail, query web page, etc.) that is transmitted in a small amount for a short period of time in the network may be stored in the second storage table as data that meets the second condition.
Specifically, a traffic size standard and a traffic rate standard may be preset in the data forwarding device, where the traffic size may be determined according to a duration of data transmission and a data amount. The data forwarding device can divide target data according to the flow size standard and the flow rate standard, and store the target data which accords with the flow size standard and the flow rate standard into the first storage table as data which accords with the first condition; and storing the target data which does not accord with the flow rate standard or the flow rate standard into a second storage table as data which accords with a second condition. Or the flow size standard and the flow rate standard can be classified into grades, and the data meeting the first condition or the data meeting the second condition is determined according to the grade met. Wherein, the data meeting the first condition can also be called large-traffic type data, elephant flow data and the like; the data conforming to the second condition may also be referred to as small flow type data, mouse flow data, or the like. In addition, in the context of data transmission, typically a small amount of data, a larger amount of traffic (occupying a higher bandwidth) is provided; the large amount of data provides less traffic (occupies less bandwidth) and therefore the data in the first memory table is typically less than the data in the second memory table. Thus, data that meets a first condition may also be referred to as small entry data, and data that meets a second condition may also be referred to as large entry data.
An elephant flow is understood to mean a process of transferring data continuously in a large quantity through a network link; a mouse flow is understood to mean a small, short-term data transfer process over a network link. Data of the corresponding first category and the second category are determined based on the elephant flow and the mouse flow.
In an alternative embodiment, the first storage table may be determined according to a priority level of the target object. In an alternative embodiment, the data forwarding device obtains priority information of the target object; and determining first identification information of the target object meeting the priority standard as the first storage table based on the priority information. The target object may be a client corresponding to the second end, a service corresponding to the second end (such as a data storage service), and so on. The priority levels may include a first priority and a second priority, and the conforming levels may be determined according to priority criteria. And setting the priority corresponding to the target object in the data forwarding equipment, and storing the priority into a corresponding storage table by the data forwarding equipment according to the priority.
For example, the target object may be understood as a client, and the priority corresponding to the client may be set in the data forwarding device according to the traffic characteristics of the data related to the client. It is determined whether the traffic size and traffic rate of the client-related data meets the traffic size criteria and the traffic rate criteria. For the clients meeting the traffic size standard and the traffic rate standard, setting the clients as a first priority in the data forwarding device, and storing the mark information (first identification information) of the clients into a first storage table by the data forwarding device; for clients which do not meet the traffic size standard or the traffic rate standard, setting the clients as a second priority in the data forwarding device, and storing the identification information of the data forwarding device into a second storage table according to the priority information of the data forwarding device.
The characteristic information of the target data may be identification information of the target data corresponding to the first storage table in which the identification information is stored. After determining the first storage table storing the identification information, the data forwarding device may determine whether the identification information of the target data exists in the first storage table corresponding to the first programmable component; if the identification information of the target data exists in the first storage table, determining that the characteristic information of the target data accords with the first condition; and if the identification information of the target data does not exist in the first storage table, determining that the characteristic information of the target data accords with the second condition. By determining whether the identification information of the target data exists in the first storage table, it is possible to quickly determine whether the characteristic information of the target data meets the first condition or meets the second condition.
In an alternative embodiment, the first memory table may also be determined based on the traffic rate and traffic size of the target object over the historical period. Specifically, the data forwarding device collects corresponding flow characteristics of a target object in a target period; and determining second identification information of the target object meeting the flow standard based on the flow characteristic as the first storage table. Specifically, the target object may be a client, and the flow rate and the flow size of the data related to the client in the target period may be collected, and the client is classified based on a preset flow standard. Taking clients with the flow rate and the flow size meeting the flow standard as a first category; and taking clients with the flow rate and the flow size which do not accord with the flow standard as second categories. A first memory table may be generated for a first class of clients and a second memory table may be generated for a second class of clients. In this embodiment, the flow rate and the flow size in the history period corresponding to the target object may be obtained at regular time, so that the corresponding first storage table and second storage table may be updated at regular time, so that the accuracy of the data in the storage table may be improved, and the forwarding efficiency of the target data may be improved.
After determining that the characteristic information of the target data meets the first condition or meets the second condition, in step 104, if the characteristic information of the target data meets the first condition, forwarding the target data through the first programmable component; in step 106, if the characteristic information of the target data meets the second condition, the data forwarding device forwards the target data through the second programmable component.

The FPGA device belongs to a semi-custom circuit in an application-specific integrated circuit, is a programmable logic array, and has the characteristics of rich wiring resources, repeated programming and high integration level, so that the FPGA device is widely applied to the field of digital circuit design. DDR SDRAM is a device that can transfer data twice in one clock cycle, once in the rising and falling periods of the clock.
In an alternative embodiment, FIG. 2 illustrates the transmission flow of target data by the first programmable component and the second programmable component.

The first programmable component then forwards the target data in a forwarding manner and a speed limiting manner.
For target data meeting the second condition, after the first programmable component receives the target data, the first programmable component sends the target data to the second programmable component. The double-rate synchronous dynamic random access memory of the second programmable component matches the target data in the lookup table to determine the forwarding mode of the target data, and determines the speed limiting mode corresponding to the target data according to the speed limiting module. The second programmable component then forwards the target data in a forwarding manner and a speed limiting manner.
The first programmable component can analyze the destination address corresponding to the target data and determine the corresponding routing information according to the destination address. The first programmable component then forwards the destination data according to the routing information. On the one hand, the data forwarding device may forward the target data to another data forwarding device; on the other hand, the data forwarding device may forward the target data to the second end. Specifically, the step of forwarding, by the first programmable component, the target data includes: analyzing the data head information of the target data through the static random access memory to obtain a first destination address; determining first routing information corresponding to the first destination address; forwarding the target data based on the first routing information.

The message comprises: a message header (or header) and a message body, where the message header may include information such as a message length, a message identifier, a source address, and a destination address. In the process of analyzing the target data by the first programmable component, the data header information (message header) of the target data can be analyzed through the static random access memory so as to obtain a first destination address corresponding to the target data. After the first programmable component obtains the first destination address, the first routing information corresponding to the first destination address may be determined by using a lookup table stored in the first programmable component, where the first routing information may also be referred to as routing path information, forwarding manner, and the like, and includes a routing path corresponding to the target data.

After the second programmable component obtains the second destination address, a lookup table stored in the second programmable component may be used to determine second routing information corresponding to the second destination address, where the second routing information includes a routing path. The second programmable component determines a next site (which may be a data forwarding device or a second end) of the target data via the second routing information and forwards the target data to the next site. In addition, the embodiment adopts the double data rate synchronous dynamic random access memory to analyze the data header information of the target data, and can analyze the target data with longer data header information.
In an optional embodiment, in the embodiment of the present application, the process of forwarding the target data by using the programmable component may first buffer the target data in the data forwarding device, and forward the buffered target data. In another example, the target data may be buffered in the data forwarding device first, then the buffered target data is grouped and each group of target data is forwarded separately. In addition, the data forwarding device can utilize the cached target data to verify the target data which is completed to be forwarded, and re-forward the target data which is abnormal under the condition that the target data which is completed to be forwarded is abnormal.
