Example Embodiment

[0014] The present invention will be described in further detail below through specific examples.

[0015] A switch technology that supports function expansion. The method is based on the hardware structure of the existing switch and realizes the expansion of the switch function based on the FPGA chip, and maximizes the function of the switch.

[0016] Implementation of key technologies for the realization of this method:

[0017] The implementation of the present invention includes the connection between the switch chip of the switch and the FPGA, the implementation of the present invention includes the connection between the management CPU of the switch and the FPGA, and the implementation of the present invention includes the connection between each FPGA.

[0018] (1) Data transmission between the switching chip and FPGA: Add a PHY (BCM5241) at the port of the switching chip (BCM53262). One side of the BCM5241 is connected to the switching chip BCM53262, and the other side is conn...

Abstract

An interchanger supporting function extension comprises an outer shell and a circuit board arranged in the outer shell, optical module receiving and sending device interfaces, namely, SFP interfaces, PHY chips, a switch chip, a management CPU and an FPGA are arranged on the circuit board, the SFP interfaces input an external signal passing through the interfaces to the PHY chips, the PHY chips are connected with one end of the FPGA, the other end of the FPGA is connected with the second PHY chip, and finally the FPGA is connected into the switch chip through the PHY chips. The management CPU is connected with the switch chip through an MII. On the basis of the structure, diversified software functional development can be performed, and the use value of the interchanger is maximized.

Description

technical field [0001] The invention belongs to the communication field in the power system, in particular to a switch used in the power system. Background technique [0002] With the rapid development of network technology, switches play an increasingly important role in modern people's lives, and at the same time people have higher and higher requirements for switches. [0003] At present, most of the switches on the market adopt a structural system of a dedicated switch chip and a management CPU. In this system, the switch chip is responsible for the storage and forwarding of data frames, and the CPU is responsible for the setting and management of the switch chip and the processing of some protocol messages. Due to the limited resources of the CPU, more functions cannot be developed on it. It is not very realistic to propose a specially customized switching chip or management CPU. A switch technology that supports function expansion is proposed, which can develop diver...
