[0023] In order to make the purpose, technical solution and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0024] Embodiment 1

[0025] Figure 1AThis is a flow chart of a method for configuring a service table provided in Embodiment 1 of the present application. This embodiment can be applied to configuring a service table in a memory. The method can be executed by a device for configuring a service table in an embodiment of the present application. The device can be implemented by software and / or hardware and can generally be integrated in a network device. The method specifically includes the following steps:

[0026] S110 , converting the format of the acquired target data to obtain table writing data, and writing the table writing data into a cache queue.

[0027] Network devices (e.g., switches, bridges, routers, and fiber optic transceivers) manage the operation of various network protocols through the control layer, such as the spanning tree protocol, VLAN (Virtual Local Area Network) protocol, ARP protocol (Address Resolution Protocol), routing protocol, and multicast protocol, so that network devices can understand the devices, links, and interaction protocols in the entire network environment, and also process and forward various types of data on different ports through the data forwarding layer; the control layer provides the data forwarding layer with various network information and service tables required for data forwarding; the service table is also the forwarding query table item (e.g., port table, medium access control (MAC) table, and routing table, etc.), the data layer sends data according to these forwarding query table items, and the control layer stores these forwarding query table items in various memories, such as static random access memory (SRAM), ternary content addressable memory (TCAM), and synchronous dynamic random access memory (SDRAM).

[0028] The acquired target data is integrated according to a preset format to obtain table writing data conforming to the preset format, so that the table writing data is suitable for the table writing operation.

[0029] The cache queue adopts a producer / consumer model to store table write data, and writes the table write data into the cache queue, that is, as a producer, it performs an enqueue operation, and the asynchronous table write thread acts as a consumer to perform a dequeue operation; optionally, in an embodiment of the present application, the cache queue can be a ring structure; the cache queue with a ring structure separates the enqueue operation and the dequeue operation of the table write data from each other and can be performed simultaneously, thereby improving data flow efficiency.

[0030] Optionally, in an embodiment of the present application, before the acquired target data is format-converted, it also includes: creating a cache queue set according to the memory type and / or the chip bus type; wherein the cache queue set includes at least one cache queue; since in a network device, different types of memories use different chip buses (for example, a PCI-E bus and a Local Bus bus), for example, a routing table exists in a ternary content-addressable memory and is written through the PCI-E bus; and a service table existing in a double data rate (DDR) memory is written through a network processor (NP) bus; therefore, one or more cache queues can be created according to the memory type and / or the chip bus type, and accordingly, the table write data is written into the cache queue, including: writing the table write data into a matching target cache queue in the cache queue set; specifically, the table write data can be written into a corresponding cache queue according to the data type of the table write data.

[0031] Optionally, in the embodiment of the present application, there is no specific limitation on the type of network device, the type of memory, the type of chip bus, and the type of service table.

[0032] S120, reading the table writing data from the cache queue through an asynchronous thread, and writing the table writing data into a memory through a chip bus.

[0033] The function of the asynchronous thread is to read the table write data from the cache queue; after reading the table write data through the asynchronous thread, the table write interface is mobilized and written into the memory through the chip bus.

[0034] Optionally, in an embodiment of the present application, after creating a cache queue set according to the memory type and / or chip bus type, it also includes: creating an asynchronous thread set according to the cache queue set; wherein the asynchronous thread set includes at least one asynchronous thread, and the asynchronous thread is matched one-to-one with the cache queue; accordingly, reading the write table data from the cache queue through the asynchronous thread includes: obtaining a target asynchronous thread matching the target cache queue in the asynchronous thread set, and reading the write table data from the target cache queue through the target asynchronous thread.

[0035] The table writing data includes all information for executing the business table operation; wherein, if the business table type is not preset, the table writing data includes a processing function and processing parameters; wherein, the processing function includes a table writing function or a table deletion function; accordingly, writing to the memory through the chip bus includes: performing an operation of adding or deleting the business table to the memory through the chip bus; if the business table type is not preset, then it is necessary to specify the processing function to be used in the table writing data, and by calling the processing function, add the business table to the memory or delete the business table. If the business table type has been preset, the table writing data includes an operation type and processing parameters; wherein, the operation type includes adding or deleting; accordingly, writing to the memory through the chip bus includes: performing an operation of adding or deleting the business table to the memory through the chip bus; if the business table type has been preset, then the corresponding processing function has been fixed, and at this time, the corresponding processing function does not need to be included in the table writing data, and it is only necessary to specify whether the operation type of the business table is adding or deleting, and the business table can be added or deleted in the memory according to the operation type.

[0036] The technical solution provided by the embodiment of the present application writes table write data into a cache queue, reads the table write data from the cache queue through an asynchronous thread, and then writes it into a memory, so that the write operation of the table write data is separated from the read operation. At the same time, different chip buses work in parallel and are written into corresponding memories respectively, so that the business table configuration operations in each memory can be performed simultaneously, which greatly improves the configuration efficiency of the business table.

[0039] S210. The forwarding table management unit assembles the data transmitted by the upper platform into table writing data.

[0040] The upper-layer platform is a module in the network device used for sending and receiving network protocol messages and protocol calculation.
