Method for configuring shared table item resource pool, packet switching method, chip and circuit

Abstract

The invention discloses a method for configuring a shared table item resource pool, a packet switching method, a packet switching chip and a packet switching circuit. The packet switching circuit comprises an input port processing module, a routing resource processing module, a shared table item cache processing module and an output port processing module, wherein the shared table item cache processing module is respectively connected with the input port processing module and the output port processing module through the routing resource processing module. According to the method, chip re-customization and chip re-throwing are not needed, only the chip flow needs to be reconfigured, the method can adapt to a new application scene, and the method has the advantages of being high in universality, high in flexibility and the like; in addition, the cost can be reduced, and the tape-out manufacturing efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of cache management, and more specifically relates to a method for configuring a resource pool of shared entries, a packet switching method, a packet switching chip and a packet switching circuit. Background technique [0002] Packet switching, also known as packet switching, divides the data transmitted by the user into a certain length, each part is called a packet, and a packet header is added in front of each packet to indicate the address to which the packet is sent. The switch then forwards the packet to the destination address based on the information in each packet header. Traditional packet switching chips support fixed packet types and packet services, and the supported business scope is customized according to current needs. After chips, all functions of the packet switching chip are fixed, and the size of the processed behavior entry cannot be changed. [0003] However, when the subsequent requ...

Problems solved by technology

[0004] Aiming at the above defects or improvement needs of the prior art, the present invention provides a method for configuring a shared entry resource pool, a packet switching method and a packet switching chip, the purpose of which is to modify the processed behavior table when the requirement changes or the protocol update needs to be modified. When the table entry depth of the item is high, it only needs to reconfigure the process of the chip to adapt to the new application scenario and has versatility, thereby solving the technical problems of long time period and high cost of manufacturing new tape-outs
