Kilomega and tens of kilomega Ethernet composite card and implementation method thereof

Abstract

The invention provides a kilomega and tens of kilomega Ethernet composite card and an implementation method thereof. The kilomega and tens of kilomega Ethernet composite card comprises a central processing unit (CPU) control module, an optical module, a serial-parallel conversion module, a transceiver module, a firmware memory module, a peripheral component interface express (PCIE) bridge chip module, an internal memory module, a parameter memory module, an algorithm memory module, an RS232 interface chip module and two PCIE*4 downlink ports, wherein the CPU control module is a many-core processor and is connected with the serial-parallel conversion module, the transceiver module, the firmware memory module, the algorithm memory module, the parameter memory module, the PCIE bridge chip module, the internal memory module and the RS232 interface chip module; a system file protection (SFP) module comprises two SFP interfaces and two SFP+ interfaces; the two SFP+ interfaces are connected with the CPU control module through the serial-parallel conversion module; and the two SFP interfaces are connected with the CPU control module through the transceiver module. The many-core processor serves as a CPU processing module of the network card, so that the performance, the power consumption and the cost are balanced.

Description

technical field [0001] The invention relates to a high-performance network card, in particular to a gigabit and ten gigabit Ethernet composite network card. Background technique [0002] In the current market, there are generally several ways to implement 10GbE network cards: dedicated ASIC, NP processor, and FPGA. The solution implemented with ASIC has the highest line speed, but the function is very single and cannot be flexibly changed; the solution implemented with FPGA is very flexible in design, but the cost and performance are poor; the solution implemented with NP is powerful but costly, and because of its special architecture Programming is difficult. [0003] In view of the above problems, the present invention provides a way to implement a network card by using a many-core processor to achieve a balance between performance, power consumption and cost. Contents of the invention [0004] A Gigabit Ethernet composite network card provided by the present invention...
