Abstract

The invention embodiment discloses a multi-core router. The internal bus of the multi-core router is based on PCIE which connects the master control board of the multi-core router to the backboard of the multi-core router; the multi-core router further internally includes a network board and at least an interface board, wherein the network board and the interface board are respectively connected with the backboard via PCIE, thus to realize data transmission; and the master control board includes a multi-core CPU which respectively controls the network board and the interface board. The invention embodiment can effectively save hardware resources and reduce power consumption.

Description

technical field [0001] The embodiment of the present invention relates to the communication field, and in particular to a multi-core router. Background technique [0002] Existing distributed routers include a main control board, a backplane, an interface board, and a network board. The main control board is a collection of multiple functional modules. The management of the entire router can Realize mutual communication with the interface board and network board. In the prior art, each interface board and network board have a separate central processing unit (CPU, Central Processing Unit), and the CPU is also connected with the bootrom chip and the flash chip, wherein the bootrom chip is used for starting the CPU, and the flash chip is used for starting the CPU. The chip is used to save relevant configuration data. When the interface board is started, it will initialize the Ethernet communication controller, send a message to the main control board through the backplane, an...
