In order to facilitate understanding of the technical solutions provided by the present invention, the following detailed description will be made with reference to embodiments of specific scenarios.
Aiming at the defects of the existing FTTR all-optical network energy-saving technology, the embodiment of the invention provides an all-optical network energy-saving device, which solves the problem of high energy consumption of the all-optical network. Fig. 5 is a schematic structural diagram of an all-optical network energy saving device according to an embodiment of the present invention, and it should be noted that the division of the module functions in this embodiment is not exactly the same as the previous embodiment. As shown in fig. 5, the apparatus may include: the energy-saving detection module 21, the energy-saving issuing module 22, the energy-saving recovery module 23 and the abnormality protection module 24.
Specifically, the energy-saving detection module 21 can continuously detect the alarm signal of the optical gateway in an interrupt mode, a timer training mode or a process scanning mode, and when the alarm signal is detected to be generated by the optical gateway, the alarm type of the alarm signal can be judged, wherein the alarm type comprises a power-off alarm, a fiber-break alarm, a wire-dropping alarm, a business failure alarm, and the like, and the alarm energy-saving issuing module 22 is notified to prepare for the alarm information. In the present embodiment, the energy saving detection module 21 is functionally equivalent to the function of the monitoring module 30 in the above-described embodiment.
The energy-saving issuing module 22 is responsible for communicating with the down-hanging optical router, when the optical gateway detects the alarm signal, the alarm signal is sent to the MinOlt module, and after the MinOlt module receives the alarm signal, the alarm information is issued to each optical router in different modes according to different alarm types. In the present embodiment, the energy saving issuing module 22 functionally includes the functions of the notification module 10 and the initiation module 20 in the above-described embodiment.
In this embodiment, when the optical gateway detects an LOS alarm, the optical gateway will turn on the LOS lamp, at this time, the optical gateway LOS lamp blinks to prompt the optical gateway to lose the optical signal packet, and at the same time, the optical gateway sends the LOS alarm information to the MinOlt module, and the MinOlt module notifies the down-hanging optical router through the private PLOAM message or OMCI message, and after receiving the alarm information, the optical router synchronously operates the alarm indicator lamp to turn on the LOS alarm lamp to prompt the backbone network to have the LOS alarm, so as to realize the alarm synchronization of the down-hanging optical router and the optical gateway.
In this embodiment, when the optical gateway is dropped by the OLT, the service is abnormal, the PON lamp of the optical gateway blinks, and the optical gateway continuously monitors the registration state, when the registration state is overtime, the optical gateway sends the dropped alarm information to the MinOlt module, and after the MinOlt module receives the dropped alarm information, continuously monitors the alarm state, and when the alarm recovery message is not received over time, the MinOlt notifies the down-hanging optical router that the working state of the optical gateway has been dropped through the private PLOAM message or OMCI message, and synchronizes the PON lamp of the optical router to blinks, so as to realize the alarm synchronization of the down-hanging optical router and the optical gateway.
In this embodiment, when the optical gateway is powered down, the service is abnormal, and the optical gateway sends power-down alarm information to the MinOlt module at the moment of power failure, so as to prompt the optical gateway to power down, and after the MinOlt module receives the power-down alarm information, the MinOlt informs the down-hung optical router through a private PLOAM message or OMCI message, the working state of the optical gateway is dropped, and the alarm indicator of the optical router is synchronized to flash, so that the alarm synchronization of the down-hung optical router and the optical gateway is realized.
In this embodiment, after the MinOlt module receives the above alarm information, the MinOlt module actively initiates a low-power consumption process while issuing the alarm information to the down-link router, so as to force the down-link router to start an energy-saving state machine, and after the energy-saving interaction is completed, the optical router closes the peripheral circuit to reduce power consumption. Specifically, the energy-saving interaction can be realized through an energy-saving state machine flow conforming to the g.984.3 or g.987.3 standard, or a low-power consumption flow can be realized by adopting a private PLOAM message or OMCI message.
After the optical gateway detects the alarm recovery signal, the service state of the optical gateway is continuously detected, when the service state is detected to be normal, the energy-saving recovery module 23 can send an alarm recovery message to the MinOlt module, and after the MinOlt module receives the alarm recovery message at the moment, the Mint module can inform the down-hanging optical router through a private PLOAM message or an OMCI message that the alarm is recovered, and the state of the synchronization point state indicator lamp is kept synchronous with the state of the optical gateway. In this embodiment, the energy saving recovery module 23 may be functionally equivalent to the recovery module 50 in the above-described embodiment.
In this embodiment, after receiving the alarm resume message, the MinOlt module initiates a wake-up low power flow to force the down-link router to wake up on line.
The anomaly protection module 24 protects the abnormal alarm signal, when the optical gateway detects the alarm signal frequently, the alarm signal is notified to the MinOlt module frequently, and the MinOlt module is forced to start energy-saving interaction with the optical router frequently, so that impact is caused to the all-optical network, and the occurrence of the situation needs to be avoided as much as possible. The anomaly protection module 24 is functionally equivalent to the protection module 40 in the above-described embodiment.
Specifically, the anomaly protection module 24 counts the detected alarm messages, and adopts a timing polling mode, when an alarm is generated, minOlt issues the alarm messages, initiates energy-saving interaction, continuously detects the alarm state in energy saving, and when the same alarm is repeatedly triggered in a short time in a timer period, the anomaly protection module 24 does not immediately issue the alarm to the down-link router, thereby avoiding the state switching of the down-link router for frequent alarms to generate anomalies.
According to the embodiment of the invention, through the four modules, the alarm states of the FTTR optical gateway and the optical router can be ensured to be synchronous, and meanwhile, the MinOlt module is prompted to send a message through the alarm signal, so that the lower hung optical router enters the energy-saving state, and the optical router can enter the energy-saving state in the alarm state, thereby achieving the purpose of reducing energy consumption. The energy-saving processing method for the alarm state in the embodiment has the following characteristics and advantages:
firstly, in the embodiment, the energy-saving processing is mainly aimed at the down-hung optical router, the optical gateway always keeps a monitoring state, once the service is recovered, the optical gateway can immediately inform the down-hung optical router to wake up, the service recovery time is short, the service recovery of a user is quick, and the user experience is improved; secondly, the energy-saving protection module 24 can effectively protect abnormal alarm signal impact, so that the problem that the optical gateway frequently issues alarm information due to external factors is avoided, and the impact of continuous alarm information on a user network is avoided; finally, the energy-saving issuing module 22 can synchronize the alarm state of the optical gateway in real time, and inform the user of the network state of the FTTR networking in an indicator lamp mode, so that the trouble that the user needs to check the FTTR networking equipment one by one when the user is not working for the service is eliminated, and the usability of the user is further improved.
The embodiment of the invention also provides an all-optical network energy-saving processing method, and fig. 6 is a flow chart of the all-optical network energy-saving processing method, as shown in fig. 6, the method can comprise the following steps:
s601: the optical gateway detects the alarm signal at regular time.
Specifically, the optical gateway may continuously monitor the optical gateway alarm signal by means of an interrupt or a timer.
S602: the optical gateway judges whether the alarm signal is detected or not, and only the effective alarm signal is taken for issuing within the time length of the timer.
Specifically, the optical gateway determines whether an alarm signal is detected, if no alarm signal is detected, continues detection, and if an alarm signal is detected, proceeds to step S603.
S603: the optical gateway sends alarm information to the MinOlt module, and the MinOlt module sends alarm information and energy-saving instruction to the optical router to require the optical router to enter an energy-saving state.
Specifically, after the alarm signal is generated, the optical gateway judges whether the alarm signal is an unstable alarm signal which is frequently reported in the time length of the timer, if the alarm signal is the frequent alarm signal in the time length of the timer, the optical gateway only issues the alarm information corresponding to the alarm signal once to the MinOlt module, so that the frequent alarm is prevented from impacting the network, and the MinOlt module can send the alarm information to the optical router through private PLOAM or OMCI information so as to inform the optical router to keep synchronous with the alarm state of the optical gateway.
Further, after the MinOlt module receives the alarm information, the MinOlt module actively initiates a low-power consumption flow, forces the down-hanging router to start an energy-saving state machine, and after the energy-saving interaction between the MinOlt module and the optical router is completed, the optical router enters an energy-saving state.
S604: after the optical gateway monitors the alarm recovery, the optical gateway sends alarm recovery information to the MinOlt module, and the MinOlt module sends alarm recovery signals and energy-saving recovery instructions to the optical router so as to enable the optical router to exit the energy-saving state.
Specifically, when the optical gateway monitors alarm recovery, the optical gateway sends alarm recovery information to the MinOlt module, and the MinOlt module can notify the underhung optical router through the private ploam message or the omci message according to the received alarm recovery information, and the optical router switches to the alarm recovery state after receiving the alarm recovery information so as to keep synchronous with the state of the optical gateway.
Furthermore, after receiving the alarm recovery message, the MinOlt module may initiate a wake-up low power flow via PLOAM or OMCI message to force the down-link router to wake up on line.
Through the steps of the embodiment of the invention, the normal operation of the FTTR networking can be ensured, and simultaneously, the energy-saving treatment is carried out on the FTTR networking in an alarm state, so that the low energy consumption of the FTTR networking in the alarm state is ensured, the power consumption of the FTTR networking is greatly reduced, and the economic applicability of the FTTR networking can be further improved.
