Rate is detected.
Photoelectric conversion unit (not shown) can be set in Fig. 1 and cluster routers shown in Fig. 2, on SFU,
The electric signal of FE output is converted to optical signal by photoelectric conversion unit, and is output to cascade port.Hereafter, by cascading port
The optical fiber of institute's grafting, by the machine frame of optical signal transmission to opposite end, to complete the forwarding across machine frame in cluster routers.FE's
After multiple pins are drawn, it is connected to a connector, and photoelectric conversion unit is plugged by the connector, thereafter, photoelectricity turns
It changes unit and is connected to cascade port, wherein a pin corresponds to the single line cable on an optical fiber, the number received and dispatched on the pin
According to being transmitted by cable corresponding on optical fiber.
Multiple first registers are can integrate inside FE, each first register pair answers a pin, for recording
Bit error rate when data is received on the pin.In addition, can also integrate multiple second registers inside FE, each second is posted
Storage can correspond to a pin, enabled for control that the pin data outputs and inputs.For example, in the second register
When value is " 0 ", the input and output for enabling data on corresponding pin are gone, i.e., this cable are set to DOWN state；Second
When value in register is " 1 ", the input and output of data on corresponding pin are enabled, i.e., this cable are set to UP state.
The port events for cascading port include UP event and DOWN event.If it is determined that the port events received are UP
Event can then remove the aging cumulative frequency of cascade port；The connection optical fiber for cascading port, which can also be removed, is included
A plurality of cable the bit error rate, that is, remove cascade port a plurality of cable generate CRC quantity.
FE records the state of the cascade port, that is, is denoted as UP state after the UP event for receiving cascade port.
At this point, aging identification information is labeled as first identifier, that is, start the aging timing for the cascade port.FE can distinguish
The aging cumulative frequency for recording each cascade port carries out an aging accumulation metering after aging timing reaches preset time
Several countings.For example, expression starts to carry out aging timing to cascade port when the value of aging mark information is set to 1,
And the cable for starting the optical fiber connected to cascade port carries out fault detection, when being set to 0, indicates to stop to cascade end
The aging timing of mouth, and terminate to detect the cable of cascade the connected optical fiber in port.
After receiving the UP event of a cascade port, then illustrate that the cascade port has been connected to an optical fiber, it can
To form cluster, the transmission of starting row data with the machine frame of opposite end.So, FE is needed value recorded in each second register
" 1 " is set to be enabled, allows pin to carry out data and outputs and inputs, and remove recorded in each second register
The bit error rate restarts to record.Data transmission during, then may occur due to the part cable on optical fiber virtual connection or
The case where person's disconnection.Due to the appearance of such situation, data packetloss can be caused, lead to the accumulation of the bit error rate.
In the present embodiment, testing conditions are preset as according to the state of the aging cumulative frequency of cascade port, cascade port
(UP state or DOWN state), and the aging identification information of cascade port determine, specifically will in the following embodiments
It is introduced.
It in the present embodiment, can be to cascade port cable in the case where cascade port reaches default testing conditions
The bit error rate (that is, quantity of cyclic redundancy check code CRC) is detected, and is recorded in corresponding first register.
Optionally, in the present embodiment, can to judge whether the cascade port meets by following three kinds of modes default
Testing conditions.
Mode one:
If the aging cumulative frequency of the cascade port is more than or equal to preset threshold, it is determined that meet the default inspection
Survey condition.
Specifically, in the present embodiment, if the port events received in step S302 are UP event, described in removing
After the bit error rate for a plurality of cable that the optical fiber that the aging cumulative frequency and cascade port for cascading port are connected includes, starting is fixed
When device.If timing arrives, the aging cumulative frequency of cascade port is obtained, and judges that the aging cumulative frequency for cascading port is
It is no to be more than or equal to preset threshold.It is if judging, it is determined that meet above-mentioned default testing conditions, and to the bit error rate of cable
It is detected.If the bit error rate that testing result is cable is higher than default value, DOWN state is set by the cable.
Mode two:
If from preset time, the cascade port is begun to pass through at the time of removing the aging cumulative frequency for cascading port
State be continuously UP state, and the aging identification information of the cascade port is continuously second identifier, it is determined that described in satisfaction
Default testing conditions, wherein the second identifier indicates that the cable for starting the optical fiber connected to the cascade port is examined
It surveys.
Specifically, in the present embodiment, if the port events received in step S302 are UP event, described in removing
After the bit error rate for cascading the aging cumulative frequency of port and a plurality of cable of cascade the connected optical fiber in port, start timer.
If timing arrives, from preset time is begun to pass through at the time of removing the aging cumulative frequency for cascading port, judge to cascade end
Whether the state of mouth is continuously UP state, and the aging identification information of judgement cascade port is continuously second identifier.If sentenced
It is disconnected to be out, it is determined that meet the default testing conditions, wherein the second identifier expression starts to the cascade port company, institute
The cable for connecing optical fiber is detected.
Mode three:
If the aging cumulative frequency of the cascade port is more than or equal to preset threshold, it is determined that meet the default inspection
Survey condition.
If from preset time, the cascade port is begun to pass through at the time of removing the aging cumulative frequency for cascading port
State be continuously UP state, and the aging identification information of the cascade port is continuously second identifier, it is determined that described in satisfaction
Default testing conditions, wherein the second identifier indicates to start to detect the cable of cascade the connected optical fiber in port.
If the bit error rate that testing result is cable is higher than default value, DOWN state is set by cable.
Based on above-mentioned three kinds of modes, the default value of aging cumulative frequency, the timing of timer and the bit error rate can
To be configured based on experience value, the range of setting is with no restrictions.
Step S308 sets the cable to if the bit error rate that testing result is the cable is higher than default value
DOWN state.
Specifically, in the present embodiment, if the port events received in step S302 are UP event, described in removing
After the bit error rate for a plurality of cable that the aging cumulative frequency and cascade the connected optical fiber in port for cascading port include, starting timing
Device.If timing arrives, obtain cascade port aging cumulative frequency, and judge cascade port aging cumulative frequency whether
More than or equal to preset threshold, which can be configured according to actual needs, such as 3 times.And judge from clear
Preset time is begun to pass through at the time of except the aging cumulative frequency for cascading port, judges whether the state for cascading port is continuously UP
State, and the aging identification information for cascading port is continuously second identifier.If it is judged that being, it is determined that meet the default inspection
Survey condition, wherein the second identifier indicates to start to detect the cable of cascade the connected optical fiber in port.If detection
As a result it is higher than default value for the bit error rate of cable, then sets DOWN state for cable.
In an optional embodiment, this method further includes following steps: if the optical fiber that the cascade port is connected
More cables in the cable of preset quantity be arranged to DOWN state, then set DOWN state for the cascade port, and
Isolation processing is carried out to the cascade port.
Certain route table items can be stored on FE, with guidance to received data can by which port into
Row forwarding if the outgoing interface for the route table items being matched to is cascade port, needs to pass through when receiving a message
It cascades port and carries out across machine frame forwarding.Data input and output can not be carried out when multiple cables in an optical fiber have been in
DOWN state is then actually matched to when the route table items are forwarded it is possible that can not the case where data jamming
Meet transmission requirement, then can delete corresponding to the optical fiber route table items that cascade port is related to, avoid receiving message after
It is continuous to be matched to the route table items, thus the problem of further resulting in data jamming.
Since the optical fiber that is connected of cascade port is comprising more cables, and two machines can be connected to by multifiber
Between frame, i.e., in connection, configuring redundancy will not cause cluster routers when occurring situations such as guaranteeing a certain optical fiber broken string
It seriously affects, but if cascade port can not perceive cable fault, then data may continue to transmit on the cable, with the time
Passage, the loss of data can exist always.At this point, on an optical fiber, if cable fault quantity included in it increases
Add, then the loss of data can continue to increase.Therefore, it can determine fault wire in optical fiber that the cascade port of itself is connected in FE
When cable reaches a preset quantity, which is directly turned off, then it can be to avoid this lasting loss of data, to keep away
Exempt from the expansion influenced.
Above-mentioned preset quantity can be set according to actual needs, for example, can be connected according to cascade port
The total quantity of the cable of optical fiber presets a fixed numbers as preset quantity；A ratio value can also be preset,
For example, 0.6 or 0.7, if it is determined that be arranged to out the cable of DOWN state quantity be more than the total quantity of 0.6* cable (or
The total quantity of person's 0.7* Internal cable), then isolation processing is carried out to the cascade port.In the present embodiment, really to preset quantity
Determine process to be not specifically limited, for that can be set according to actual needs.
It should be noted that in the present embodiment, after carrying out isolation processing to cascade port, restarting timing
Device waits the timing of next cycle to arrive, and repeat the above steps process described in S302 to step S308, herein no longer
It repeats.
It should be noted that in the present embodiment, if the port events received are UP event, can be delayed one section
Time and then starting timer, and after starting the timer, execute above-mentioned steps S306 and step S308.
The purpose of delay a period of time and then starting timer is to become UP state from DOWN state in cascade port,
And after cascade port status keeps stable state, it can guarantee the accuracy for cascading port-action processing, while also can the period
The failure that monitoring processing equipment occurs in operational process, guarantees cluster device reliability.
In conclusion in the present embodiment, becoming UP state from DOWN state in the cascade port of cluster routers, and locate
After stablizing UP state, whether the cable of the regular check cascade port has occurred failure, if it find that there is the corresponding FE of cable
Pin be in the state of enable and DOWN, alternatively, the CRC (error code of cable that the data that receive on some pin occur
Rate) be greater than default value, then it can set cable to DOWN state.
By above-mentioned processing mode, cause when efficiently solving cable fault corresponding to cluster routers cascade port
Cluster routers the problem of continuing packet loss, this method can guarantee the stability and reliability of cluster routers.
