Embodiment 1

[0071] Please refer to figure 1 , Embodiment 1 of the present invention is:

[0072] A method for expanding multiple network ports in an embedded system, such as figure 1 shown, including steps:

[0073] S1. The embedded central processing terminal 2 receives the first message sent by the switch chip terminal 5, and the first message includes a first label for identifying the source network port;

[0074] S2. The embedded central processing terminal 2 replaces the first label of the first message with the second label identifying the destination network port to obtain the second message;

[0075] S3. The embedded central processing terminal 2 forwards the second message to the destination network port through the switching chip terminal 5 .

[0076] In this embodiment, step S2 is specifically:

[0077] The embedded central processing terminal 2 obtains the destination network port corresponding to the source network port according to the preset protocol stack rules, replac...

Embodiment 2

[0078] Please refer to figure 1 and figure 2 , the second embodiment of the present invention is:

[0079] A method for expanding a plurality of network ports in an embedded system, on the basis of the above-mentioned embodiment 1, the following steps are included before step S1:

[0080] S0. The switching chip terminal 5 receives the source message from the source network port, puts the first label corresponding to the source network port on the source message, obtains and sends the first message.

[0081] In this embodiment, step S3 is specifically:

[0082] The embedded central processing terminal 2 sends the second message to the switching chip terminal 5;

[0083] The switch chip end 5 receives the second message, and determines the destination network port according to the second label of the second message;

[0084] The switch chip end 5 strips the second label from the second message to obtain the source message;

[0085] The chip switching end sends the source p...

Embodiment 3

[0098] Please refer to image 3 , Embodiment three of the present invention is:

[0099] A kind of embedded system expands the system 1 of a plurality of network ports, comprises embedded central processing end 2, and embedded central processing end 2 comprises first memory 4, first processor 3 and is stored on the first memory 4 and can be in The first computer program running on the first processor 3, when the first processor 3 executes the first computer program, implements the steps performed by the embedded central processing terminal 2 in the first embodiment above.

Abstract

The invention discloses a method and system for expanding a plurality of network ports of an embedded system, and the method comprises the steps: receiving a first message from one of a plurality of external network ports on a switching chip end, replacing a first label, used for identifying a source network port, on the first message with a second label, used for identifying a target network portof the first message, and obtaining a second message; forwarding the second message to the destination network port through the switching chip end according to the content of the second label, so themulti-network-port requirement of embedded products in the communication field is met, and meanwhile, the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and system for expanding multiple network ports in an embedded system. Background technique [0002] At present, embedded system-level chips based on ARM architecture are widely used in various fields including mobile phones, communications, and industrial control. The field of network security communication has also extended from the original X86 platform to embedded platforms of various general-purpose CPUs based on ARM. In this type of CPU, there are usually only a few Ethernet controllers in consideration of cost, power consumption, energy efficiency, etc., which makes it unable to meet the needs of products in the communication field with dozens or even dozens of network ports. . [0003] The traditional X86 multi-network port solution is to expand multiple PCIE network cards through the PCIE (high-speed serial computer expansion bus standard) bus to reali...
