Problems solved by technology

When the bandwidth required for table lookup is less than the bandwidth provided by the number of copies, it will cause a waste of the number of banks; if the bandwidth required for table lookup is greater than the bandwidth provided by the number of copies, it is necessary to add another set of copy blocks , which will also cause a waste of storage resources
In addition, when the number of remaining banks is not enough to place a group of replicated blocks, it will also cause waste of storage resources

Embodiment Construction

[0048] In a typical configuration of the present application, a computing device includes one or more processors (CPUs), input / output interfaces, network interfaces, and memory.

[0049] Memory may include non-permanent storage in computer readable media, in the form of random access memory (RAM) and / or nonvolatile memory such as read only memory (ROM) or flash RAM. Memory is an example of computer readable media.

[0050]Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read only memory (ROM), Electrically Erasable Programmable Read-Onl...

Abstract

The invention discloses a table entry copying method and device, and the method comprises the steps: determining the number of copies and the shape after copying according to the resource demands needed by a table entry; selecting a basic copy unit according to the determined copy number and the copied shape; and copying the table item according to the attribute of the selected basic copying unit.According to the method and the apparatus, the purpose of few configuration parameters required for a copying purpose is achieved through a plurality of preset basic copying units, and the plasticityof the copying shape is very good, so that the efficiency and usability during table item copying are improved, and the storage resources are fully utilized.

Description

technical field [0001] The present application relates to but is not limited to communication data processing technology, especially a method and device for replicating entries. Background technique [0002] During the processing of network communication packets, it is necessary to match the characteristic fields of the packets through table lookup for forwarding. There are two main storage methods for entries: external memory and embedded memory. Among them, the external memory mainly includes synchronous dynamic random-access memory (SDRAM, Synchronous dynamic random-access memory). SDRAM has the characteristics of large capacity, high storage density and low price, but the bandwidth utilization rate is low. In the design of using SDRAM as the embedded storage, because the SDRAM needs to be refreshed continuously, and in order to prevent conflicts with the read and write operations during the refresh, it is generally limited to refresh a memory bank (bank), so the current...
