Abstract

The invention discloses an ONU management method and an ONU management system under a vOLT cluster architecture, which relate to the technical field of communication.

Description

ONU management method and system under vOLT cluster architecture
Technical Field
The invention relates to the technical field of communication, in particular to an ONU (optical network unit) management method and system under a vOLT (virtual line terminal) cluster architecture.
Background
In an access Network system, each physical OLT (Optical line terminal) hangs a plurality of ONUs (Optical Network units), and each physical OLT independently processes ONU configuration data and status data that are hung down. For example, when a large number of ONUs are on-line simultaneously, there are many data packets that need to process the configuration and state of the ONUs, and the processing capability of a single OLT is limited, which may cause the on-line process of the ONUs to be long and the user experience to be poor. In addition, since an ONU belongs to a specific OLT, when the ONU needs to be migrated to another OLT, the ONU needs to be newly configured on the new OLT, and the configuration of the original OLT cannot be automatically migrated to the new OLT.
The current network functional unit with separated and standardized control and forwarding can effectively respond to the challenges of the access network; the Network is reconstructed through Network Function Virtualization (NFV), functions of existing proprietary equipment are fused, Network hop count is reduced, Network delay can be effectively reduced, and challenges faced by an access Network are met; by means of NFV, the functional part of the terminal device is moved upwards, especially the value added service part, so that the device form life cycle can be prolonged, and the challenge of the access network can be met.
A cluster is a group of mutually independent computers interconnected by a high-speed network, which form a group and are managed in a single system mode. A client interacts with a cluster, which appears as a stand-alone server. The cluster configuration is for improved availability and scalability. Each node in the cluster can bear certain processing load, and dynamic distribution of the processing load among the nodes can be realized so as to realize load balance. For network traffic load, when the network service program receives high network access traffic and cannot process the traffic quickly, the network traffic is sent to the network service program running on other nodes. At the same time, optimization can be performed according to different available resources on each node or the special environment of the network.
However, in the above scenario, the ONU data of the own OLT is processed independently by each physical OLT, and the following problems still exist:
1. when the ONUs are online in batch, a large amount of time is required for processing the ONU states and configuration data.
2. ONU configuration belongs to each OLT, ONU migration needs reconfiguration, and migration is difficult.

vOLT: virtual optical line terminal.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
The embodiment of the invention provides an ONU management method under a vOLT cluster architecture, which comprises the following steps:
referring to fig. 1, in the downstream direction, the vlolt module receives ONU configuration data and sends the ONU configuration data to the cluster center; the cluster center comprises a plurality of ONU protocol processing modules, stores ONU configuration data into a configuration data queue, searches for an idle ONU protocol processing module, sends the ONU configuration data to the idle ONU protocol processing module for processing, sends the ONU configuration data to the entity OLT according to the ip of the entity OLT, and forwards the ONU configuration data to the ONU by the entity OLT;

Preferably, the method further comprises the steps of: when the ONU configuration data is stored in the configuration data queue or the ONU state data is stored in the state data queue, the data is stored in the queue with the corresponding priority according to the priority of the ONU configuration data or the ONU state data belonging to the ONU;
and when the ONU configuration data is sent to the idle ONU protocol processing module for processing or the ONU state data is sent to the idle ONU protocol processing module for processing, the data in each queue is sent to the idle ONU protocol processing module for processing in sequence according to the priority sequence of the queue. By classifying the ONUs, the load sharing module preferentially processes data of the high-priority ONUs.
Preferably, the searching for an idle ONU protocol processing module specifically includes the following steps: setting a plurality of ONU protocol processing modules respectively corresponding to entity OLTs at different geographical positions, setting ONU protocol processing modules corresponding to the entity OLTs at the same geographical position to share the same domain name, and respectively sharing different domain names by the ONU protocol processing modules corresponding to the entity OLTs at different geographical positions;
and searching for the idle busy state of the ONU protocol processing module under the corresponding domain name according to the geographical position of the entity OLT, and returning to the IP of the idle ONU protocol processing module.
The role of the domain name is: when the vOLT module or the entity OLT needs to communicate with the ONU protocol processing modules, detailed IP of each ONU protocol processing module does not need to be known. The message can be sent to the domain name only by knowing the domain name shared by the ONU protocol processing module. And then the load sharing module determines which ONU protocol processing module is specifically selected to process the message.
Each ONU protocol processing module has an independent and unique IP, each ONU protocol processing module can be distinguished through the IP, and the load sharing module sends a message to the corresponding ONU protocol processing module according to the IP.
Preferably, the method further comprises the following steps of generating a new ONU protocol processing module if all ONU protocol processing modules are in a non-idle state for a long time;

And the vOLT configures the ONU through the ONU ID, and the ONU logically belongs to the vOLT and does not belong to a specific entity OLT. The relationship table of the ONU ID and the OLT where the ONU is located exists, if the ONU migrates from one OLT to another OLT, only the corresponding relationship table needs to be modified, and ONU configuration is issued again, and the vOLT does not need to change the stored configuration. And the ONU configuration is stored in a public database, and each ONU protocol processing module accesses the database through the ONU ID to acquire related information, so that the data migration is facilitated.

And the vOLT module acquires the priority of the ONU to be sent in the ONU configuration data packet and adds the configuration packet into a queue corresponding to the priority.
The load sharing module judges whether an idle ONU protocol processing module exists in the cluster, and if the idle ONU protocol processing module exists in the cluster, the load sharing module preferentially processes the configuration packet in the queue with high priority. Only after no packets to be processed exist in the high priority queue, packets in the low priority queue are processed in sequence. And the load sharing module delivers the taken configuration packet to an idle ONU protocol processing module for processing. The load sharing module detects each priority queue, and if the number of packets to be processed in a certain level is found to be excessive and exceeds a preset upper limit threshold value continuously for a period of time, which indicates that the number of the ONU protocol processing modules in operation is too small, the cluster system is required to generate more ONU protocol processing modules to accelerate the process of processing the ONU configuration packets. On the contrary, when the number of the messages to be processed in all the priority queues continuously exceeds a preset lower threshold for a period of time and is less than the preset lower threshold, indicating that an idle ONU protocol processing module exists in the cluster, the number of the ONU protocol processing modules in operation can be reduced.
