Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for controlling an operating state of a channel terminal.
Background
With the development of Network technology, a large amount of services such as voice, data, video and the like can be transmitted by using a Network, so that the requirement for bandwidth is continuously increased, and a Passive Optical Network (PON) is generated under the requirement. As shown in fig. 1, a topology structure of a PON system generally includes an Optical Line Terminal (OLT) on a central office side, an Optical Network Unit (ONU) on a user side, and an Optical Distribution Network (ODN), and generally adopts a point-to-multipoint Network structure. The ODN is composed of a single-mode optical fiber, an optical splitter, an optical connector, and other passive optical devices, and provides an optical transmission medium for physical connection between the OLT and the ONU.
With the further increase of bandwidth demand, a topology structure of a proposed TWDM PON (Time-and Wavelength-Division Multiplexed PON, a passive optical network based on Time Division and Wavelength Division multiplexing) system is shown in fig. 2, where the TWDM PON network includes an OLT, an optical distribution network, and a plurality of ONUs, and each OLT includes a plurality of OLT channel terminals. The TWDM PON network is provided with a plurality of TWDM PON channels, each OLT channel terminal and a group of ONUs work on one TWDM PON channel, and each TWDM PON channel comprises a downstream wavelength channel and one or a plurality of upstream wavelength channels. And one OLT channel terminal on each TWDM PON channel manages a group of ONUs, the uplink wavelengths of the group of ONUs for sending uplink data are the same, the downlink wavelengths for receiving the downlink data are also the same, and different ONUs in the group of ONUs transmit the uplink data in a time division multiplexing mode. The downstream wavelengths of different TWDM PON channels are different, and the upstream wavelengths used by each group of ONUs managed by different OLTs are also different. Each ONU transmits upstream data in a specific upstream time slot according to the command of the OLT. In addition, for reasons of load balancing, energy saving, reduction of the inventory types of ONUs and the like, the transmission wavelength and the reception wavelength of the ONUs in the TWDM PON system can be tuned, and the OLT can command the ONUs to tune the operating wavelength, so that the ONUs can operate in any TWDM PON channel. According to the transmission requirement of the service data, the OLT configures an OLT channel terminal to communicate with the ONU. How the OLT channel terminals are in the TWDM PON when there are a plurality of OLT channel terminals
When the traffic of the PON network is small, the OLT may only open part of the OLT channel terminals for communicating with the ONUs, and close the optical module of one or more OLT channel terminals, so that part of the OLT channel terminals enter an energy-saving state. When the PON network has a large amount of traffic, the OLT needs to increase and open some OLT channel terminals to enter a working state from an energy-saving state. The prior art does not provide a method for the OLT to enter an energy-saving and working state recovery.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Fig. 3 is a flowchart of a method for controlling an operation state of a channel terminal according to the present invention. The method of fig. 3, comprising:
and step 302, the first OLT channel switches the operating state of the first OLT channel terminal according to the switching instruction, wherein the operating state includes an energy-saving state and a working state.
The embodiment of the method provided by the invention controls the change of the running state of the first OLT channel terminal by acquiring the switching instruction, thereby realizing energy conservation and ensuring the balance of data transmission.
The above method is further illustrated below:
wherein, the first OLT channel terminal acquiring the switching instruction of the operating state includes:
the first method is as follows: the first OLT channel terminal receives a switching instruction which is sent by the OLT and enters an energy-saving state or a working state;
specifically, when the OLT detects that the data volume of the service data to be transmitted increases or a fault occurs in a part of the PON channels, the OLT notifies the first OLT channel terminal entering the energy-saving state to switch to the working state; and when the OLT detects that the data volume of the service data needing to be transmitted is reduced, the OLT notifies the first OLT channel terminal entering the working state to switch to the energy-saving state.
The second method comprises the following steps: the first OLT channel terminal receives a switching instruction which is sent by a second OLT channel and enters an energy-saving state or a working state;
specifically, when the second OLT channel detects that the data volume of the service data to be transmitted increases or a part of the PON channels fails, the second OLT channel notifies the first OLT channel terminal entering the energy-saving state to switch to the working state; when the second OLT channel detects that the data amount of the service data to be transmitted decreases, the second OLT channel notifies the first OLT channel terminal which enters the working state to switch to the energy-saving state.
The third method comprises the following steps: and the first OLT channel terminal detects that the data volume of the service data needing to be transmitted is reduced or zero, and generates a switching instruction for entering an energy-saving state.
From the above, the wake-up command may be received externally, such as sent by the OLT or other OLT channel terminals, or may be generated by itself.
In an embodiment provided by the present invention, the switching, by the first OLT channel, the operating state of the first OLT channel terminal according to the switching instruction includes:
if the switching instruction is generated according to the transmission requirement information with reduced data volume of the service data to be transmitted, the first OLT channel terminal requests the second OLT channel terminal to enter an energy-saving state, and sends ONU transmission convergence layer configuration information of a passive optical network TWDM PON channel which is based on time division and wavelength division multiplexing and corresponds to the second OLT channel terminal;
and after receiving a message which is sent by the second OLT channel terminal and agrees that the first OLT enters the energy-saving state, the first OLT channel terminal enters the energy-saving state.
Specifically, when the first OLT channel terminal detects that the amount of the service data is reduced, that is, when the first OLT channel terminal still has no service data to send, in order to ensure that the data transmission of the ONU corresponding to the first OLT channel terminal is not affected after the first OLT channel terminal enters the energy-saving state, the second OLT channel terminal continues to complete the unfinished data transmission task of the first OLT channel by sending the ONU transmission convergence layer configuration information to the second OLT channel terminal, and enters the energy-saving state after receiving that the second OLT channel terminal agrees to continue to complete the data transmission task instead of the first OLT channel terminal, thereby ensuring the continuous transmission of the data on the premise of realizing energy saving.
Wherein, whether the second OLT channel terminal agrees the first OLT channel terminal to enter the energy-saving state includes:
the second OLT channel terminal allocates bandwidth to the ONU corresponding to the first OLT channel terminal on the TWDM PON channel managed by the second OLT channel terminal according to the ONU transmission convergence layer configuration information sent by the first OLT channel terminal;
after the second OLT channel terminal completes bandwidth allocation, whether a new ONU sending uplink frame to the TWDM PON channel managed by the second OLT channel terminal is received or not is judged;
and if the second OLT channel terminal receives that the new ONU sends an uplink frame on the TWDM PON channel managed by the second OLT channel terminal, the first OLT channel terminal is allowed to enter an energy-saving state.
Specifically, after the second OLT channel terminal allocates a bandwidth to the ONU corresponding to the first OLT channel terminal on the TWDM PON channel managed by the second OLT channel terminal, the preparation work for replacing the first OLT channel terminal to continue transmitting data is completed, if an uplink frame sent by the ONU originally communicating with the first OLT channel terminal on the TWDM PON channel managed by the second OLT channel terminal can be received, which indicates that the sending of subsequent data can be completed by replacing the uplink frame, the first OLT channel terminal is allowed to enter an energy-saving state, and if not, the first OLT channel terminal is rejected to enter the energy-saving state.
The above description is made when the data amount of the traffic data to be transmitted is reduced, and unlike the above case, the following description is made when the data amount of the traffic data to be transmitted is zero:
and if the switching instruction is generated according to the transmission requirement information that the data volume of the service data to be transmitted is zero, the first OLT channel terminal enters an energy-saving state, and sends information that the first OLT channel terminal enters the energy-saving state to the second OLT channel terminal.
Specifically, when the first OLT channel terminal detects that the amount of the service data is zero, that is, the first OLT channel terminal has no service data to send, that is, whether the first OLT channel terminal is dormant or not does not affect data transmission of the ONU corresponding to the first OLT channel terminal.
In the above description, the switching of the first OLT channel terminal to the power-saving state is described, and the switching of the first OLT channel terminal to the operating state is described as follows:
wherein, the switching the operating state of the first OLT channel terminal by the first OLT channel according to the switching instruction includes:
if the switching instruction is generated according to the data volume increase of the service data to be transmitted or the information that the TWDM PON channel has a fault, the first OLT channel terminal enters a working state, receives the ONU transmission convergence layer configuration information of the TWDM PON channel corresponding to the first OLT channel terminal, and executes bandwidth allocation operation by using the received ONU transmission convergence layer configuration information.
The switching instruction may be obtained by:
the first OLT channel terminal receives a switching instruction which is sent by the OLT and enters an energy-saving state;
specifically, when the OLT detects that the data volume of the service data to be transmitted increases or a fault occurs in a part of the PON channels, the OLT notifies the OLT channel terminal entering the energy-saving state to switch to the working state;
alternatively, the first and second electrodes may be,
the first OLT channel terminal receives a switching instruction which is sent by a second OLT channel and enters an energy-saving state or a working state;
specifically, when the second OLT channel detects that the data amount of the service data to be transmitted increases, the second OLT channel notifies the first OLT channel terminal entering the energy-saving state to switch to the working state.
In the above flow, the purpose of data transmission is achieved by acquiring the ONU transmission convergence layer configuration information, executing bandwidth allocation operation by using the received ONU transmission convergence layer configuration information, and communicating with the ONU by using the allocated bandwidth, thereby effectively reducing the transmission pressure of data in the network.
