Technical Field

At present, many communication devices integrate a hundred mega/giga optical fiber/twisted pair communication interface, and users want to plug and unplug a network cable at will to keep the devices in a normal communication state, so that the problem of free switching between electrical signals and optical signals is faced. At present, many devices need a method that a user inputs an operation command or logs in a webpage first and then clicks to select a communication medium when switching between the photoelectric devices, and although the method can meet the requirement and the switching is not frequent, the method wastes time and labor after all.

The adaptive processing of hundreds of mega/giga of fiber/twisted pair is added in driving the bundled physical layer PHY implementation. On need not any operation can automatic identification and switch to concrete physical medium when practical scene, convenient and fast has avoided manual operation's loaded down with trivial details, has greatly promoted user experience.

Detailed Description

The present invention is further illustrated by the following description in conjunction with the accompanying drawings and the specific embodiments, it is to be understood that these examples are given solely for the purpose of illustration and are not intended as a definition of the limits of the invention, since various equivalent modifications will occur to those skilled in the art upon reading the present invention and fall within the limits of the appended claims.

A connection method of photoelectric free switching, as shown in fig. 1 and 2, comprising the following steps:

step 1, the MAC layer driver is associated with the physical layer PHY, and the MAC layer driver can always read the current state of the physical layer PHY after the physical layer PHY is bound.

And 2, switching the physical layer (PHY) register to an optical communication mode to detect whether light energy exists or not because optical communication is preferred.

And 3, switching to an electric signal mode if no light energy exists, configuring the physical layer PHY to the electric signal mode, and then setting PHY attributes including full duplex, rate, auto-negotiation, state and the like.

And 4, if light energy is detected, the optical fiber is inserted currently, but hundreds of megabytes or gigabytes need to be detected.

And 5, detecting whether the current light energy parameter is consistent with the last stored value:

in step 51, if the current optical energy parameter is detected to be inconsistent with the last stored value, for example, the last giga is detected, and the energy parameter is different in this hundred mega, the PHY of the physical layer is reset first.

And step 52, resetting the required time, increasing printing, reading the hundred mega flag register of the current physical layer PHY, if the hundred mega flag register is successfully set, indicating that the physical layer PHY is reset, and otherwise, exiting.

In step 53, the PHY attribute at this time is set.

Step 54, detecting the connection status if the current optical energy parameter is detected to be consistent with the last stored value.

Step 541, if it is Link Up state, directly setting PHY attributes including full duplex, rate, auto-negotiation and state.

Step 542, if not in Link Up state, automatically defining a hundred mega optical interface, and setting a hundred mega attribute of the PHY, which is a method designed for the problem that many devices cannot adapt to a hundred mega optical fiber, that is, light energy is found but cannot adapt.

At this point, the algorithm ends.

As shown in the network deployment of fig. 1, the device communication interface has the following three insertion modes:

1) only inserting the twisted pair;

the next hop is connected with a hundred mega/kilomega switch, and the equipment can obtain an IP address and normally receive and transmit data packets;

2) plugging hundreds of mega/giga optical fibers;

the next hop of a hundred mega/giga optical switch or an optical-to-electrical converter can be self-adaptive, and can be freely switched among hundred mega/giga optical fiber communication.

3) The optical fiber and the twisted pair are simultaneously inserted.

Since optical communication is preferred, it is selectively connected to an optical switch/optical-to-electrical converter, which converts an input optical signal into an electrical signal and then forwards the electrical signal. Even if the twisted pair interface is pulled out, the equipment is not influenced.

The optical interface accommodates hundreds of megabits/gigabytes by negotiating with the optical switch/optical-to-electrical converter, with normal communication of data. When the optical port is unplugged, the equipment can be automatically switched to the twisted-pair interface, and data can still be normally communicated.

The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
