Embodiment Construction

[0026] Such asfigure 1 As shown, the system adopts a multi-channel input and output interface structure design. The access unit 1 includes a 2.5GPOS interface, a 10G POS interface and a Gigabit interface. Bus interconnection, the bandwidth resource of the SPI bus is 10G, data communication is carried out between the main control unit 2 and the security inspection unit 3 through the PCI (external device interface) bus, the bandwidth resource of the PCI bus is 1000MBps, the main control unit 2 and the exchange output The units 4 are interconnected through an SPI (System Packet Interface) bus, and the bandwidth resource of the SPI bus is 10G.

[0027] Such as figure 2 As shown, the access unit is composed of 10G photoelectric signal conversion module, 2.5G POS photoelectric signal conversion module CP-3395 and framing chip IXF19301. The 10G photoelectric signal conversion module and 2.5G conversion module cannot be used at the same time. The two modules are connected through the...

Abstract

The safe filtering flow divider consists of access unit, main control unit, safety examination unit and exchange output unit connected together. The access unit consists of 10G photoelectronic signal converting module, 2.5G POS photoelectronic signal converting module and frame forming chip; the main control unit consists of network processor unit and four channels of giga level physical interfaces; the safety examination unit consists of four standard CPU processing modules with giga level electric interface; and the exchange output unit consists of giga level main exchange control module, giga level electric interface module and giga level optical interface module. The safety examination unit returns the examining result to the main control unit, and the main control unit makes the data flow dividing policy based on the filtering result and distributes the data flow dividing policy to the exchange output unit for data transmission.

Description

technical field [0001] The invention relates to a data processing device in a high-speed network traffic environment, in particular to a security filter splitter based on a network processor and a CPU array switching architecture, which is used in the field of network information technology. Background technique [0002] In recent years, my country's broadband backbone network has developed rapidly. At present, the bandwidth of most regional backbone networks has reached 2.5G, and the bandwidth of some backbone networks has reached 10G or even 40G. Judging from the development of the Internet in the past 10 years, the speed of the processor doubles every 18 months, but the bandwidth of the Internet backbone connection doubles every 12 months. It can be seen that how to meet the high-speed data processing requirements of broadband networks based on the performance of existing processors is the key to ensuring the quality of network services. Load balancing and data shunting ...
