Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The ONU is configured to selectively receive broadcast data sent by an Optical Line Terminal (OLT), and receive a response to the OLT if the data needs to be received; and collecting and buffering Ethernet data required to be sent by a user, and sending the buffered data to the OLT end according to the distributed sending window. The connection structure between the OLT and the ONU is shown in fig. 1, and the ONU is connected to the OLT through an Optical Distribution Network (Optical Distribution Network, abbreviated as "ODN"). The OLT is equivalent to a switch or a router in a conventional communication network, and is also a multi-service providing platform that provides a fiber interface of a passive fiber network facing a user. The ONU is customer premise equipment in an optical network, is placed at a customer premise and is matched with the OLT for use, and provides voice, data and multimedia services for a user.
With the continuous development of PON technology, the PON rate is continuously increased from GPON to XG/XGSPON, NGPON2 to 50G PON, 100G PON, and the negotiation rate of the ONU LAN port is mostly used at 1GE or 10GE, which results in that the downstream rate is much greater than the negotiation rate of the ONU LAN port in a high-speed PON system. Take 50G PON ONU hung under 50G PON OLT as an example, wherein the LAN port of the 50G PON ONU is all GE port, and there is GE port and 10GE port. However, the negotiated rates of the LAN ports, whether the GE port or the 10GE port, cannot match the rate of the PON port, which may cause the downstream data transmission of the PON port to exceed the receiving capability of the ONU LAN port, resulting in loss of user data. Therefore, the embodiment of the invention carries out real-time detection on the traffic rate of the PON port of the ONU or the negotiation rate of the LAN port; if the negotiation rate of the LAN port is detected to be not matched with the flow rate of the PON port, reporting a notification message carrying the current negotiation rate of the LAN port to the OLT, and scheduling the transmission rate of the downlink service flow by the OLT according to the notification message so as to avoid the problem of user data loss possibly caused when downlink data is sent due to the fact that the negotiation rate of the ONU LAN port is not matched with the rate of the PON port.
An embodiment of the present invention relates to a method for controlling a transmission rate of an ONU, which is applied to the ONU, and the specific flow is shown in fig. 2. In this embodiment, the downstream traffic flow of the ONU is normal, but the rate of the downstream traffic flow is greater than the rate of the LAN port due to a change in the negotiated rate of the ONU LAN port. And the ONU reports the change of the negotiation rate of the ONU LAN port to the OLT actively, and the OLT schedules and optimizes the downlink service after receiving the change. The flow of fig. 2 is described in detail below:
in step 201, the onu detects the traffic rate of the PON port or the negotiated rate of the LAN port in real time. In this embodiment, the ONU normally receives the downstream service stream in the normal online operation, and in this step, the ONU mainly performs real-time detection on the negotiation rate of the LAN port.
In step 202, the ONU detects the matching degree of the negotiation rate of the LAN port and the flow rate of the PON port according to the detection result. In one example, the negotiation rate will change due to manual forced negotiation of the ONU LAN port, or during auto-negotiation. However, when the negotiated rate of the ONU LAN port changes, the PON port rate may be greater than the negotiated rate of the ONU LAN port, which means that the downstream data sent by the PON port exceeds the receiving capability of the ONU LAN port, which may cause loss of user data, and this rate mismatch needs to be handled. Therefore, in this step, after detecting that the negotiated rate of the LAN port has changed, the matching degree between the negotiated rate of the LAN port and the traffic rate of the PON port is detected.
In one example, the negotiation rate of the LAN port of the ONU is detected in real time, and if it is detected that the negotiation rate of the LAN port changes and the changed negotiation rate is lower than the negotiation rate before the change, the detection of the matching degree between the negotiation rate of the LAN port and the traffic rate of the PON port is triggered. Under the condition that the downlink service flow is normal, the negotiation rate of the LAN port is lowered, and the loss of user data is possibly caused, so that the detection of the matching degree is triggered after the change of the negotiation rate of the LAN port is determined to be changed from high to low, unnecessary matching detection can be avoided, and the operating efficiency of the system is improved.
Step 203, if it is detected that the negotiated rate of the LAN port is not matched with the traffic rate of the PON port, reporting a notification message carrying the current negotiated rate of the LAN port to the OLT, so that the OLT schedules the transmission rate of the downlink service stream according to the notification message. In one example, the change of the negotiated rate capability of the OLT with respect to the ONU LAN Interface is reported by the ONU through an optical network unit Management and Control Interface ("OMCI").
Specifically, since the negotiated rate of the ONU LAN port changes, the downstream traffic flow rate is greater than the rate of the LAN port, and at this time, the OMCI actively sends a message to the OLT, and reports the change of the negotiated rate of the ONU LAN port, so that the OLT can schedule the transmission rate of the downstream traffic flow according to the current negotiated rate of the LAN port carried in the notification message, thereby avoiding the loss of user data.
In another example, the determination of whether the negotiated rate after the change is lower than the negotiated rate before the change may not be performed, and as long as the change of the negotiated rate of the LAN port is detected, the negotiated rate of the LAN port is reported to the OLT, so as to notify the OLT that the rate supported by the LAN port of the ONU changes, thereby increasing the downlink rate of the PON port.
In another example, if it is detected that the negotiated rate of the LAN port is not matched with the traffic rate of the PON port, a notification message carrying the current negotiated rate of the LAN port may also be reported to the OLT through a Physical Layer Operations Administration and Maintenance (PLOAM) message.
Because the OMCI and the PLOAM messages are mature information interaction mechanisms with the OLT, the ONU can select to send the notification message through an OMCI reporting mechanism and also can select the PLOAM message to send the notification message, so that the OLT can smoothly receive the notification message carrying the current negotiation rate of the LAN port, the downlink service is scheduled and optimized, and the downlink sending data of the PON port is ensured not to exceed the receiving capacity of the LAN port of the ONU. The OLT in this embodiment may support GPON/XGPON/XGSPON/50GPON, for example, but not limited thereto.
Another embodiment of the present invention relates to a transmission rate control method for an ONU, which is applied to the ONU, and in this embodiment, the negotiated rate of the LAN port is not changed, and the OLT downstream traffic flow rate is abruptly changed. When the downstream traffic flow rate sent by the OLT PON port exceeds the negotiated rate of the ONU LAN port, the ONU detects the rate capability exceeding the LAN port, and the ONU actively reports that the traffic flow rate is greater than the negotiated rate of the ONU LAN port and informs the OLT to carry out scheduling.
Specifically, in step 201, the ONU detects the traffic rate of the PON port in real time.
In step 202, the ONU detects the matching degree between the negotiated rate of the LAN port and the traffic rate of the PON port based on the detection result of the traffic rate of the PON port.
In one example, the traffic rate of the PON port of the ONU is detected in real time, and if it is detected that the traffic rate of the PON port changes and the changed traffic rate is higher than the traffic rate before the change, the matching degree between the negotiated rate of the LAN port and the traffic rate of the PON port is detected. Since the traffic rate at the PON port of an ONU may be greater than the negotiated rate at the LAN port of the ONU after the traffic rate at the PON port of the ONU changes, this means that the downstream data sent by the PON port exceeds the receiving capability of the LAN port of the ONU, which may cause the loss of user data, and the case of rate mismatch needs to be handled. Therefore, when the traffic rate of the PON port becomes higher, the matching degree detection of the negotiation rate of the LAN port and the traffic rate of the PON port is triggered, which can avoid loss of user data on the one hand, and avoid unnecessary matching detection on the other hand, thereby improving the operating efficiency of the system.
In step 203, if it is detected that the downstream traffic flow rate of the OLT is greater than the negotiated rate of the LAN port of the ONU, that is, the negotiated rate of the LAN port is not matched with the traffic rate of the PON port, a notification message carrying the current negotiated rate of the LAN port is reported to the OLT, so that the OLT schedules the transmission rate of the downstream traffic flow according to the notification message.
In an example, the ONU may select to report the negotiated rate supported by the LAN port to the OLT through an OMCI reporting mechanism, or select a PLOAM message to report the negotiated rate supported by the LAN port to the OLT. After receiving the notification message, the OLT can schedule and optimize the downlink burst according to the notification message, so that the downlink data sent by the PON port does not exceed the receiving capacity of the ONU LAN port, and the loss of user data is avoided.
Another embodiment of the present invention relates to a method for controlling a transmission rate of an ONU, which uses an OLT, and the specific flow is shown in fig. 3.
Step 301: the OLT receives a notification message reported by the ONU; the notification message is triggered and reported after the ONU detects that the negotiation rate of the LAN port of the ONU is not matched with the flow rate of the PON port of the ONU, and the notification message carries the current negotiation rate of the LAN port. And after the OLT acquires the notification message, the OLT stores the negotiation rate supported by the ONU LAN port in the notification message.
In one example, the OLT receives a message that the negotiated rate of the ONU LAN port changes, which is reported by the ONU through the OMCI, and stores the message after acquiring the negotiated rate supported by the ONU LAN port.
In another example, the OLT receives a message that the negotiated rate of the ONU LAN port has changed, which is reported by the ONU through a PLOAM message, and stores the message after acquiring the negotiated rate supported by the ONU LAN port.
Step 302: and the OLT schedules the transmission data according to the rate capability supported by the ONU LAN port.
In one example, after receiving the negotiated rate information supported by the ONU LAN port, the OLT performs scheduling optimization on the downlink burst so that the data sent by the PON port in the downlink does not exceed the receiving capability of the ONU LAN port.
After receiving the notification message carrying the negotiation rate of the LAN port of the ONU, the OLT in this embodiment schedules the transmission rate of the downstream service stream according to the negotiation rate of the LAN port of the ONU, thereby avoiding the problem of user data loss.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.

In one example, the reporting module 402 reports the notification message to the OLT through the OMCI; or reporting a notification message to the OLT through the PLOAM message.
In an example, the detection module 401 detects a negotiated rate of the LAN port of the ONU in real time, and if it is detected that the negotiated rate of the LAN port changes and the negotiated rate after the change is lower than the negotiated rate before the change, detects a matching degree between the negotiated rate of the LAN port and a traffic rate of the PON port.
In another example, the detection module 401 detects a traffic rate of a PON port of an ONU in real time, and detects a matching degree between a negotiated rate of the LAN port and the traffic rate of the PON port if it is detected that the traffic rate of the PON port changes and the changed traffic rate is higher than a traffic rate before the change.
Compared with the related art, when the ONU provided in this embodiment detects that the negotiated rate of the LAN port is not matched with the traffic rate of the PON port, the ONU triggers reporting of a notification message carrying the current negotiated rate of the LAN port to the optical line terminal OLT, so that the OLT can quickly grasp the condition that the negotiated rate of the LAN port is not matched with the traffic rate of the PON port, and can schedule the transmission rate of the downstream service flow, thereby avoiding the problem of user data loss.

a scheduling module 502, configured to schedule a transmission rate of a downlink service flow according to the current negotiated rate of the LAN port carried by the notification message.

And after receiving the negotiation rate information supported by the ONU LAN port, scheduling and optimizing the downlink burst, so that the data sent by the downlink of the PON port does not exceed the receiving capacity of the ONU LAN port.
