Description
Technical field
The present invention relates to Ethernet technology, more particularly to a kind of ethernet device attachment means and its test of application
System and method.
Background technology
Ethernet possesses auto-negotiation ability, and auto-negotiation is realized by a kind of signal for being called quick connection pulse, from
The both sides of negotiation exchange data by quickly connecting pulse.In the case of not connected in the port for possessing auto-negotiation ability,
Port can send quick connection pulse always, the concatenation ability information of oneself be included in quickly connection pulse, including support
Speed, duplex, stream control etc..If both sides support auto-negotiation, the quick connection pulse of other side, and handle can be all received
Information in quick connection pulse decodes, so as to obtain the concatenation ability of other side, then each according to oneself with other side's
Maximum concatenation ability, best connected mode is selected to be attached.Such as if both sides had both supported 10,000,000 or support 100,000,000,
Then speed is according to 100,000,000 connections, and after connection is established, quick connection pulse just stops sending.
In addition, in order to ensure also establish connection in the case where a side can not support auto-negotiation, then parallel inspection is introduced
The mechanism of survey, auto-negotiation is opened in a side, in the case that the opposing party closes auto-negotiation, establishment of connection just relies on parallel detection work(
It can realize.
So-called parallel detection mechanism is exactly, and on the device port with auto-negotiation ability, quickly connects if do not received
Pulse is connect, then detects whether the characteristic signal of 10,000,000 links or 100,000,000 links, if it is 10,000,000 equipment to detect, is not supported certainly
Consult, then generic connectivity pulse is sent on link, it is in place that generic connectivity pulse is merely representative of equipment, not comprising other extra
Information.If it is 100,000,000 equipment to detect, do not support auto-negotiation, then in the absence of data, can a straight hair on link
The idle code stream for sending 4B/5B to encode.Based on principles above, when a side does not open auto-negotiation, the side for opening auto-negotiation can only
Consult into semiduplex mode.
Current chip manufacturer can provide testing tool or test instruction allows equipment under test from output data line to realize
Send the idle code stream for testing required 4B/5B codings.But the testing tool that chip manufacturer provides typically exists
Use under Windows operating system, can not just make for some do not have the equipment under test of Windows operating system
With；The test instruction that chip manufacturer provides needs to remove Input Software code in the environment of running software, less ripe for one
Know for the personnel of software, operate inconvenient.And either testing tool still test instruction be required for looking for it is each
Different chip manufacturer helps provide, and compare and lose time.
