Problems solved by technology

[0003] However, because the switch chip adds a private information header to the Ethernet header of the message according to the private protocol, this will cause the CPU to fail to recognize the message normally because the Ethernet header of the message carries the private information header after receiving the message. Affects the distribution of packets by the CPU

[0039] like image 3 As shown, the switch chip 301 may include a CPU interface 301_1 and a peripheral interface 301_2. Here, the number of peripheral interfaces 301_2 is greater than or equal to one. The peripheral interface is used for receiving messages outside the switch chip 301 and for sending messages outside the switch chip 301 .

[0040] like image 3 As shown, the CPU 302 includes at least: a media access controller 302_1 , a buffer 302_2 , a memory 302_3 , a CPU core 302_4 , and a distribution module 302_5 . The number of CPU cores 302_4 is greater th...

Embodiment 2

[0061] see Figure 5 , Figure 5 It is a structural diagram of a network device provided by Embodiment 2 of the present application. like Figure 5 As shown, in the structural diagram of the network device provided in Embodiment 2, the network device may include: a switch chip 501 , a CPU 502 , and a logic device 503 . The network device shown in Embodiment 2 is taken as an example including only one switch chip.

[0062] like Figure 5 As shown, the switch chip 501 may include a CPU interface 501_1 and a peripheral interface 501_2.

[0063] The CPU 502 includes at least: a media access controller 502_1 , a buffer 502_2 , a memory 502_3 , a CPU core 502_4 , and a distribution module 502_5 .

[0064] In Embodiment 2, the CPU interface 501_1 of the switch chip 501 is connected to the media access controller 502_1 of the CPU 502 .

[0065] In the second embodiment, the logic device 503 is connected between the media access controller 502_1 and the buffer 502_2.

Abstract

The invention provides network equipment and a virtual device. In the present application, by adding the logic device to the network equipment, the logic device migrates the private information headeroriginally carried in the Ethernet header of the message from the Ethernet header to the position where message identification is not affected by dividing the private information header by the Ethernet header, so that the situation that identification and distribution of the message are affected due to the fact that the private information header is carried by the message is prevented.

Description

technical field [0001] This application relates to network communication technology, in particular to network equipment and virtual devices. Background technique [0002] A network device generally consists of a switch chip and a CPU. Among them, when the switch chip sends a message to the CPU, it will first add a private information header to the Ethernet header of the message according to the private protocol, and then send the message carrying the private information header to the CPU, so that the CPU can learn from the private information of the message. Get the message characteristic information in the header. The message feature information may include: the VLAN to which the message belongs, the QoS of the message, the interface information of the peripheral interface that received the message, and the like. [0003] However, because the switch chip adds a private information header to the Ethernet header of the message according to the private protocol, this will ca...
