Abstract
The invention provides a method for automatically configuring Ethernet line medium chaining, which comprises the following steps: a pseudorandom number generator generates a fixed and relatively-random sequence to configure corresponding Ethernet line connection, a signal detection circuit detects network signals, such as quick link circuit pulse, common link circuit pulse or MLT3Z(multi-level transmission 3) signals with 100 Base-T to determine whether the effective signals are received or not, and a polarity controller circuit receives the signal detection circuit and the pseudorandom number generator signals to select or change the receiving and sending polarity of the Ethernet.
Description
Technical field
The present invention is a kind of method of automatic configuration ethernet line medium linking, is to need not manually to change the method for connecting line be used to realizing ethernet line automatically to configure.
Background technology
Along with the further reduction of network cost and to the increase in demand of network, network has entered the every aspect of live and work because Ethernet at cost and use convenient, the interconnected overwhelming majority between indoor interconnected and building has still adopted ethernet technology.Ethernet link the earliest, terminal and switch, router, and the line of switch, router and Upper Switch has different cable interface types.Interconnectedly need not to consider the cable interface type and the proposition of the automatic interleaving techniques of netting twine makes the network equipment, facilitate the quick links of equipment.
And the invention provides a kind of method of automatic configuration ethernet line medium linking, and detect respectively by the signal in network, and adopted improved Polarity Control algorithm, further improved speed and the link stability of network linking.
Summary of the invention
A kind of method of automatic configuration ethernet line medium linking, the method comprises the following steps: comprise two timers, two Pseudo-random number generator, signal deteching circuit, polar configurations circuit and medium commutation circuits, two timers produce the required different timing time of input; Pseudo-random number generator 1 produces fixing relatively random order and determines to adopt the timing of timer 1 or timer 2; Pseudo-random number generator 2 produces fixing relatively random order and configures corresponding ethernet line connection; Signal deteching circuit Sampling network signal, determine whether to receive useful signal; Polar configurations circuit reception signal deteching circuit, timer, Pseudo-random number generator signal carry out the control medium commutation circuit, select to change or keep Ethernet to receive and dispatch polarity; The medium commutation circuit is controlled two docking port I/O modes, to determine to intersect input and output or parallel input and output.
Description of drawings

Fig. 1 is the logic diagram of automatic configuration ethernet line medium linking device.
Fig. 2 is the state machine of polarity controller module.
Embodiment
In the following detailed description, having described specific details comprehensively understands the present invention in order to provide.Yet the professional and technical personnel will appreciate that, the present invention also can implement with other similar details.
Automatically the method for configuration ethernet line medium linking comprises timer 1 (203), timer 2 (204), Pseudo-random number generator 1 (206), Pseudo-random number generator 2 (207), signal deteching circuit (202), polarity controller circuit (205) and medium commutation circuit (201) as shown in Figure 1.Timer 1 (203) and timer 2 (204) produce the required different timing time of input; Pseudo-random number generator 1 (206) produces fixing relatively random order and determines to adopt the timing of timer 1 or timer 2; Pseudo-random number generator 2 (207) produces fixing relatively random order and configures corresponding ethernet line connection; Signal deteching circuit (202) Sampling network signal, MLT3 (multilevel transmission 3) signal as fast link pulse, Normal Link Pulse or 100Base-T, determine whether to receive useful signal; Polar configurations circuit (205) receives signal deteching circuit (202), timer 1 (203), timer 2 (204), Pseudo-random number generator 1 (206) and Pseudo-random number generator 2 (207) and carrys out control medium commutation circuit (201), to select to change or keep Ethernet transmitting-receiving polarity; Medium commutation circuit (201) is controlled two docking port I/O modes, to determine to intersect input and output or parallel input and output.
The state transition of polar configurations circuit (205) is as shown in Figure 2:
While resetting, polar configurations circuit (205) enters (300) MDI detected state (30).Under current state, produce a random number by Pseudo-random number generator 1 (206), select timer 1 (203), or timer 2 (204), when the timing of timer is completed,, if signal deteching circuit (202) detects effective signal, enter (303) MDI stable state (31); If testing circuit (202) does not detect effective signal, by Pseudo-random number generator 2 (207), produce a random number, to determine that polar configurations circuit (205) keeps (301) in MDI detected state (30), or enter (302) MDIX detected state (32).
When polar configurations circuit (205) is in MDI stable state (31), by timer 2 regularly,, if signal deteching circuit (202) detects effective signal, keep (311) in MDI stable state (31); Signal deteching circuit (202) does not detect effective signal always else if, enters (312) MDI detected state (30).
When polar configurations circuit (205) is in MDIX stable state (32), produce a random number by Pseudo-random number generator 1 (206), select timer 1 (203), or timer 2 (204), when the timing of timer is completed,, if signal deteching circuit (202) detects effective signal, enter (323) MDIX stable state (33); If testing circuit (202) does not detect effective signal, by Pseudo-random number generator 2 (207), produce a random number, to determine that polar configurations circuit (205) keeps (321) in MDIX detected state (32), or enter (322) MDI detected state (30).
When polar configurations circuit (205) is in MDIX stable state (33), by timer 2 regularly,, if signal deteching circuit (202) detects effective signal, keep (331) in MDI stable state (33); Signal deteching circuit (202) does not detect effective signal always else if, enters (332) MDI detected state (32).
Although herein declarative description some feature of the present invention and a kind of implementation method,, for the professional and technical personnel, will there will be many modifications, replacement, variation and equivalent substitution.Therefore, protection scope of the present invention is as the criterion with the scope of appended claim.
