System and method for automatically verifying correctness of gigabit and 10 gigabit hybrid network controller

Abstract

The invention provides a system and method for automatically verifying correctness of a gigabit and 10 gigabit hybrid network controller. The system comprises a photoelectric conversion module and a programmable crystal oscillator as well as a control testing unit respectively connected with the photoelectric conversion module and the programmable crystal oscillator. The verifying method comprises the following steps of: (1) judging whether the default frequency of the programmable crystal oscillator is 125 MHz or not; (2) correcting the clock frequency or detecting a gigabit channel according to a judging result of the step (1); (3) correcting the frequency of the programmable crystal oscillator from 125 MHz to 161 MHz; and (4) detecting a 10 gigabit data channel. By using the system and method for automatically verifying correctness of the gigabit and 10 gigabit hybrid network controller, provided by the invention, network card equipment with the gigabit and 10 gigabit hybrid network controller can be used for automatically verifying the correctness of the hybrid network controller after being powered on.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a system and method for automatically verifying the correctness of gigabit and ten gigabit hybrid network controllers. Background technique [0002] In the prior art, on a network card with both Gigabit and 10 Gigabit mixed network controllers, the Gigabit network controller and the 10 Gigabit network controller have their own reference clocks. Since the network card may only have one network interface, such The network card generally only provides one crystal oscillator or clock source, that is, only one kind of controller is allowed to work at the same time. When using another controller, it is necessary to change the frequency of the crystal oscillator or clock source so that the network card can switch to On another controller, there may be a situation that it cannot work normally after switching. Therefore, it is necessary to provide a method for verifying whether it can...

[0002] In the prior art, on a network card with both Gigabit and 10 Gigabit mixed network controllers, the Gigabit network controller and the 10 Gigabit network controller have their own reference clocks. Since the network card may only have one network interface, such The network card generally only provides one crystal oscillator or clock source, that is, only one kind of controller is allowed to work at the same time. When using another controller, it is necessary to change the frequency of the crystal oscillator or clock source so that the network card can switch to On another controller, it may not work normally after switching at this time. Therefore, it is necessary to provide a method to verify whether it can work normally after switching during the test phase of this type of network card.

[0003] In the existing network card equipment, the mixed mode of Gigabit and 10 Gigabit multiplexing is rarely used, and most of them are Gigabit and 100 Gigabit adaptive modes. The main reason is that the reference clock frequencies of Gigabit and 10 Gigabit are different. On network card devices equipped with Gigabit and 10 Gigabit hybrid network controllers, there are few methods for verifying the correctness of functions after switching clocks
