Embodiment

As shown in Figure 1, verifying automatically the system of 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, converts light signal into the signal of telecommunication, exports the 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; Said controller major function is to realize the processing of gigabit and 10,000,000,000 physics and link layer protocol; And a simple user interface is provided backward; The GE/10GE detection module of back notifies the controller of which path in this control to work through this interface, if notice is carried out the detection of gigabit data path, then enables gigabit PHY and gigabit mac controller; If notice is carried out the detection of 10,000,000,000 data paths, then enable 10,000,000,000 PHY and 10,000,000,000 mac controllers;

Crystal oscillator able to programme, can through iic bus to its inquire about, operation such as modification, mainly provide network processes required clock frequency, like required 125MHz clock of gigabit and 10,000,000,000 required 161MHz clocks;

The GE/10GE detection module is controlled crystal oscillator able to programme through iic bus, and through a simple interface visit GE/10GE controller, judges whether the data of the controller path that is detected are correct.

As shown in Figure 2, verify automatically to comprise the steps: the method for gigabit and 10,000,000,000 hybrid network controller correctness

After system powers on; Whether the default frequency that the GE/10GE detection module is read the codified crystal oscillator through iic bus is gigabit networking required 125MHz when handling, generally definition when programming first of the default frequency of crystal oscillator here, and the method for affirmation is; Read the address contents of this default frequency of storage; See that whether content conforms to the corresponding content of 125MHz clock frequency, and the frequency that reads crystal oscillator selects to enable the address content, see whether this default frequency is enabled;

If the clock that reads is not 125MHz; The GE/10GE detection module need write the frequency content of 125MHz in the default frequency address described in (1); And affirmation enables this frequency; Need judge whether once more to work then, promptly reading frequency content and frequency enable just can confirm once more;

If the clock that reads is correct 125MHz, then begin to carry out the detection of gigabit path.It is that the gigabit data path is to enable the controller at gigabit path place that the GE/10GE detection module is at first notified the data path of GE/10GE controller current detection; Send data code flow through a simple interface to the GE/10GE controller then, simultaneously this data code flow is deposited in inside, wait for a regular time then with certain characteristic; Like 0.5s; In the stand-by period,, then can these data returned and the data code flow of depositing before be compared by byte if the GE/10GE detection module has been received the data that the GE/10GE controller returns; If content is consistent; Represent that then the gigabit closed-circuit working is normal,, perhaps after the stand-by period finishes, still can not obtain data if content is inconsistent; Then can confirm the network controller existing problems of gigabit path, can verify the correctness of gigabit networking controller place path in view of the above;

Behind the stand-by period 0.5s,, all will get into the operation of revising crystal oscillator frequency regardless of the gigabit path result who detects; Just be the clock frequency data of 161MHz with the clock frequency data modification of 125MHz this moment;

After revising the success of 161M Hz clock frequency, begin to carry out the detection of 10,000,000,000 data paths.This testing process and gigabit data detection process are identical, the controller of 10,000,000,000 data paths in the GE/10GE module that just enables this moment.

After the fixing stand-by period; Regardless of the testing result of 10,000,000,000 data paths, the GE/10GE detection module all will withdraw from testing process, and the result who detects 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.

What need statement is that 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 the qualification to protection range of the present invention.Those skilled in the art can do various modifications, be equal to replacement or improvement under spirit of the present invention and principle inspiration.But these changes or modification are all in the protection range that application is awaited the reply.
