Problems solved by technology

[0007] from figure 2 It can be seen that the line card board can only forward and schedule the packets received by the local line card board on each core. figure 1 As shown in the figure, a distributed multi-core network device contains multiple line cards. In practical applications, it often occurs that a large number of packets appear on some interfaces, while there are few packets on other interfaces. Some line card boards are very busy, and even the messages cannot be processed in time, while other line card boards are very idle, which makes the message forwarding capability of the entire distributed multi-core network equipment low

Embodiment Construction

[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] image 3 A schematic diagram of the composition of the distributed multi-core network device provided by the embodiment of the present invention, such as image 3 As shown, it mainly includes: at least one line card board 31, a switching network card 32 and at least one centralized processing engine 33, wherein:

[0049] Line card board 31: used to detect and record the status of each core used to forward messages in this line card board: busy or idle, obtain and record the message forwarding status of other line card boards and centralized processing engine 33: busy or idle idle. Receive the message sent from the outside of the multi-core network device from the external interface of the card board of this line, and judge whether there is an idle core in the core of the card board of this line for forwarding the message, and...

Abstract

This invention discloses a kind of distributed multi-core network device and two kinds of line card boards in the device, if the device includes a centralized process engine and when the line card board receives a message out of the device, if the local card board is busy, it sends the message to the engine, which looks up the list and processes it, if the device does not include a centralized process engine and when the line card board receives a message out of the device, if the board is busy, it sends the message to an idle line card board in other line card boards to look up the list and transfer it.

Description

technical field [0001] The invention relates to the field of multi-core technology, in particular to a distributed multi-core network device and two line card boards in the distributed multi-core network device. Background technique [0002] A multi-core processor refers to the integration and packaging of multiple general-purpose central processing units (CPUs) and some functional components into one chip. For communication, compared with CPUs located on multiple chips, the processing capability of the chip is greatly improved. The multiple execution cores of the multi-core processor can completely execute instructions concurrently, and the processing capability of the processor is greatly improved without increasing the operating frequency of the processor. [0003] The network device with routing function is an indispensable part in network communication. This part completes the reception of the message, searches the forwarding table according to the address information ...
