Description
Technical field
The present invention relates to chip monitoring and breakage alarming method in the digital communicating field, specifically, relate to a kind of chip monitoring and breakage alarming method in the optical transmission field.
Background technology
At present, in optical transmission device, a lot of equipment provide the measure of some single board backup protections to protect the imperfection of agreement to service protection in order to the transmission that remedies employing.But the function that a lot of single-chip protection that provides is at present realized is very limited; except minority can detected several power alarms or the alarm of CPU related chip; auto switching took place within a few tens of milliseconds meeting triggering veneer when the appearance alarm makes outside the professional quick-recovery soon, and most of Business Stream chip on the veneer is if damage is to trigger the auto switching of veneer.Generally speaking, after finding possible alarm, can only on webmaster, issue by the attendant and switch order accordingly and go to realize professional from damaging the switching of veneer to normal veneer.From the manual switching veneer appears alarming, alarm disappears the general time of this process all can be very long, can cause the service disconnection of a few minutes even several hrs, and the user is sustained a loss.
The basic reason that causes this problem is that present equipment does not possess the ability whether real-time monitoring Business Stream chip damages.The host-host protocol alarm detection that most of Business Stream chips provide can only detect the alarm of Business Stream itself, and the monitoring range of Business Stream alarm is very wide, may cross over a plurality of equipment and optical fibre channel, can't accurate in locating in equipment, whether the position that chip damages and chip damages be arranged so detect the alarm of Business Stream, so the alarm that defines in the host-host protocol that current operation stream chip provides is the criterion that can not whether damage as chip monitoring.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method of chip monitoring and breakage alarming, can monitor the state of chip on the transmitting business stream transmission passage in real time, thereby when chip breaks down, can trigger board switchover timely, make professional recovery in time.Avoided the situation of the service disconnection that the damage because of transport service circulation road chips causes.
In order to solve the problems of the technologies described above, it is as follows to the invention provides scheme:
A kind of method of chip monitoring and breakage alarming comprises the steps:
Step 1: the transmitter side at upstream business stream chip calculates the position that the transmission data are prepared the fixed overhead of insertion, and inserts desired value in described fixed overhead position;
Step 2: the receiver side at the downstream traffic flows chip calculates the position that receives the data stationary idle overhead, and takes out the fixedly numerical value of idle overhead in described fixedly idle overhead position;
Step 3: the numerical value of the fixedly idle overhead position that will take out and desired value are relatively;
Step 4: if the numerical value of the fixedly idle overhead position of taking out is different with desired value, then in the traffic flow path device failure is arranged, and trigger and switch accordingly.
Further, in the method for a kind of chip monitoring and breakage alarming of the present invention, described fixed overhead position is meant transmitting business stream stage casing overhead byte.
Further, in the method for a kind of chip monitoring and breakage alarming of the present invention, the described desired value of inserting in the fixed overhead position is to insert a fixing self-defined byte.
Further, in the method for a kind of chip monitoring and breakage alarming of the present invention, the fixed overhead position of described transmitter side at upstream business stream chip insert numerical value that desired value takes out fixing idle overhead to the receiver side at the downstream traffic flows chip also detection be every frame once.
Further, in the method for a kind of chip monitoring and breakage alarming of the present invention, if the numerical value of the fixedly idle overhead of described taking-up is identical with desired value, then all chip and interfaces all are normal in the traffic flow path.
Compared with prior art, the invention has the advantages that:
The present invention inserts and detects the method for a fixed byte by the fixed overhead position in transmitting business stream; whether can realize monitoring transport service circulation road chips operating state normal; thereby guaranteed when failure of chip, can in time recover professional, realized single board backup protection truly.
Technical problem to be solved by this invention, technical scheme main points and beneficial effect below in conjunction with embodiment, are further described with reference to accompanying drawing.
Description of drawings
Fig. 1 is the flow chart of chip monitoring and breakage alarming method of the present invention.
Fig. 2 is the schematic diagram of the specific embodiment of the invention.
Embodiment
With reference to Fig. 1, be the flow chart of chip monitoring and breakage alarming method of the present invention.
101, calculate the position of the fixed overhead that sends data preparation insertion at the transmitter side of upstream business stream chip, and insert desired value in described fixed overhead position;
Here, described fixed overhead position is meant transmitting business stream stage casing overhead byte; The described desired value of inserting in the fixed overhead position is to insert a fixing self-defined byte.
102, the receiver side at the downstream traffic flows chip calculates the position that receives the data stationary idle overhead, and takes out the fixedly numerical value of idle overhead in described fixedly idle overhead position;
The numerical value of the fixedly idle overhead position that 103, will take out and desired value are relatively;
The fixed overhead position of described transmitter side at upstream business stream chip insert numerical value that desired value takes out fixing idle overhead to the receiver side at the downstream traffic flows chip also detection be every frame once, therefore as long as chip or signal path go wrong, 125us just can detect, and can finish the business of triggering from the switching of failing single board to normal veneer at Millisecond like this.
If the numerical value of the 104 fixedly idle overhead positions of taking out is different with desired value, then in the traffic flow path device failure is arranged, and trigger and switch accordingly.
If the numerical value of the fixedly idle overhead of described taking-up is identical with desired value, then all chip and interfaces all are normal in the traffic flow path.
With reference to Fig. 2, further specify an example of utilizing the method for the invention to carry out the cross board backup protection below.
Data flow is inserted a desired value for example 96 when business board sends in the expense position of the frame head of every data lines, desired value can be self-defining any one numerical value.As the data wire check byte.Behind business board transmission interface chip, send to cross board, behind cross board receiver side interface chip, arrive cross chips and intersect.
Whether the data wire check byte that cross chips detects the frame head place is identical with the desired value of inserting 96.If different, expression cross board receive direction has fault.
If two cross boards are detected all to be non-desired value, be expressed as business board and send and survey interface chip and damage, if a cross board is a desired value, one be non-desired value, then expression receives the cross board reception place interface chip damage of non-desired value.Can trigger switching services to normal veneer.
The method of a kind of chip monitoring and breakage alarming of the present invention, be not restricted to listed utilization in specification and the execution mode, it can be applied to various suitable the present invention's field fully, for those skilled in the art, can easily realize additional advantage and make amendment, therefore under the situation of the spirit and scope of the universal that does not deviate from claim and equivalency range and limited, the examples shown that the present invention is not limited to specific details, representational equipment and illustrates here and describe.
