Embodiment

As shown in Figure 1, the system of automatic Verification gigabit and 10,000,000,000 hybrid network controller correctness has increased detection module in gigabit and 10,000,000,000 hybrid network controller architectures;

System comprises photoelectric conversion module, GE/10GE controller, crystal oscillator able to programme and GE/10GE detection module; Photoelectric conversion module can be accepted the flow input of GE and 10GE, and light signal is converted to the signal of telecommunication, exports GE/10GE controller to; GE/10GE controller inside comprises gigabit PHY, 10,000,000,000 PHY, gigabit mac controller, 10,000,000,000 mac controllers, described controller major function is to realize the processing of gigabit and 10,000,000,000 physics and link layer protocol, and provide backward a simple user interface, GE/10GE detection module below notifies the controller of which path in this control to work by this interface, if notice is carried out the detection of gigabit data path, enable gigabit PHY and gigabit mac controller, if notice is carried out the detection of 10,000,000,000 data paths, enable 10,000,000,000 PHY and 10,000,000,000 mac controllers;

Crystal oscillator able to programme, can by iic bus to its inquire about, the operation such as amendment, mainly provide network processes required clock frequency, 125MHz clock as required in gigabit and 10,000,000,000 required 161MHz clocks;

GE/10GE detection module is by iic bus control crystal oscillator able to programme, and by a simple interface access GE/10GE controller, whether the data of the controller path that judgement detects are correct.

As shown in Figure 2, the method for automatic Verification gigabit and 10,000,000,000 hybrid network controller correctness, comprises the steps:

After system powers on, whether the default frequency that GE/10GE detection module is read codified crystal oscillator by iic bus is gigabit networking required 125MHz while processing, generally definition in the time programming first of the default frequency of crystal oscillator herein, the method of confirming is, read the address contents of this default frequency of storage, see whether content conforms to content corresponding to 125MHz clock frequency, and read crystal oscillator frequency select enable address content, see whether this default frequency is enabled;

If the clock reading is not 125MHz, GE/10GE detection module need to write the frequency content of 125MHz in the default frequency address described in (1), and confirmation enables this frequency, then need again to judge whether to work, reading frequency content and frequency enable just can determine again;

If the clock reading is correct 125MHz, start to carry out the detection of gigabit path.First GE/10GE detection module notifies the data path of GE/10GE controller current detection is that gigabit data path is to enable the controller at gigabit path place, then send the data code flow with certain feature to GE/10GE controller by a simple interface, this data code flow is deposited in inside simultaneously, then wait for a regular time, as 0.5s, within the stand-by period, if GE/10GE detection module has been received the data that GE/10GE controller returns, the data that this can be returned contrast by byte with the data code flow of depositing before, if content is consistent, represent that gigabit closed-circuit working is normal, if content is inconsistent, or until the stand-by period still can not obtain data after finishing, can determine the network controller existing problems of gigabit path, can verify accordingly the correctness of gigabit networking controller place path,

After stand-by period 0.5s, regardless of the gigabit path result detecting, all the operation of amendment crystal oscillator frequency will be entered; The clock frequency data that are now just 161MHz by the clock frequency data modification of 125MHz;

After the success of amendment 161M Hz clock frequency, start to carry out the detection of 10,000,000,000 data paths.This testing process is identical with gigabit data detection process, the controller of 10,000,000,000 data paths in the GE/10GE module just now enabling.

After the fixing stand-by period, regardless of the testing result of 10,000,000,000 data paths, GE/10GE detection module all will exit testing process, the result of detection is exported to carry out subsequent reference, usually, this result can export outside LED light to, or is uploaded to main frame, for judging whether current system exists the fault of gigabit path or 10,000,000,000 paths.

Need statement, content of the present invention and embodiment are intended to prove the practical application of technical scheme provided by the present invention, should not be construed as limiting the scope of the present invention.Those skilled in the art inspired by the spirit and principles of the present invention, can do various amendments, be equal to and replace or improve.But in the protection range that these changes or amendment are all awaited the reply in application.
