Abstract

The invention provides a network equipment and a message forwarding method; wherein, the network equipment comprises a first multicore processor and a second multicore processor. The first multicore processor comprises a first classification unit and a first forward processing unit which comprises a plurality of core units, and the second multicore processor comprises a second classification unitand a second forward processing unit which comprises a plurality of core units. By adopting the equipment and the method of the invention, the message forward processing capability of network equipment can be effectively improved.

Description

technical field [0001] The invention relates to the field of multi-core technology, in particular to a network device and a message forwarding method based on a multi-core processor. Background technique [0002] Since the invention of the microprocessor in the 1970s, the traditional von Neumann model has been followed, with some minor modifications and exceptions. To the programmer, each computer consists of a single processor, executing a preprogrammed sequence of sequential instructions, connected to a memory that stores all program data. Because the backward compatibility of early processors can bring good economics, chip designers only enhance the existing designs in principle to further improve performance, while the CPU architecture changes very little, and this trend is maintained. decades. In the past 30 years, CPU designers have mainly improved CPU performance from the following three aspects: [0003] Clock speed: Increase the tempo of CPU work and let the CPU ...
