Description
Technical field
The present invention relates to communication network device technical field, is specifically a kind of optical port self-adaptive Ethernet switch and adaptive approach thereof.
Background technology
Since fibre system commercial installation first in 1977, telephone operator just brings into use optical fiber link to substitute old communication systems as new transmission medium.Optical Fiber Transmission has highly sensitive, long transmission distance, the many advantages such as high bandwidth, also makes current most of long-distance transmissions all can use optical fiber transmission technique.
Optical Fiber Transmission needs SFP (the Small Form-factor Pluggables) optical module relying on two ends, converts the electrical signal to light signal, after then opposite end receives light, light signal is reverted to the signal of telecommunication, complete communication with this.At present, in ethernet standard agreement, defining 100,000,000 light mouths is 100Base-FX, and gigabit light mouth is 1000Base-X.
In order to allow the information desired by user can pass with the fastest speed, usually special Ethernet switch can be adopted.But because the self adaptation of light mouth scarcely supported by existing Ethernet switch, when Optical Fiber Transmission is distant, just there will be the situation cannot determining opposite end light mouth speed, once speed is not reciprocity, just cannot proper communication during connection, cause user normally cannot use Optical Fiber Transmission.At present, minority Ethernet switch is also had to support optical port self-adaptive function.This Ethernet switch preferentially uses the initial rate configuration set, if initial rate cannot connect, is switched to new rate configuration, then continues to detect whether successful connection, so repeatedly, determines final speed.But in use find, because the method preferentially uses the initial rate configuration set, if when the speed beyond initial rate need be consulted in two ends, the time connected then can be very long, not only can affect the judgement of final speed, and Consumer's Experience is poor.
Summary of the invention
For the defect existed in prior art, the object of the present invention is to provide a kind of optical port self-adaptive Ethernet switch and adaptive approach thereof, not only efficiently solve speed not reciprocity time connectivity problem, and the efficiency connected in adaptive process is high, quality good, and Consumer's Experience is good.
