[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0056] Figure 1 The flowchart of an optical line terminal interaction method applicable to an embodiment of the present invention is schematically shown.

[0057] See also Figure 1 , an embodiment of the present invention provides an optical line terminal interaction method, the method comprising the steps of:

[0058] S1: Configure the terminal controller and terminal function device on the switch;

[0059] Exemplarily, configuring the terminal controller and the terminal function device on the switch includes the following steps:

[0060] Configure switches, terminal controllers, and terminal function devices;

[0061] Configuring an Ethernet interface on the interface of the terminal controller;

[0062] Configuring an optical module on the interface of the terminal function device;

[0063] Connecting the Ethernet interface to the first network port of the switch;

[0064] Connect the optical module to the second network port of the switch.

[0065] In the embodiments of the present application, the optical line terminal includes two types of hardware: a terminal controller (OLT Controller) and a terminal function device (OLT Stick). There can be only one terminal controller, but multiple terminal function devices can exist. The terminal controller is primarily responsible for the management and control functions of the optical line terminal, such as data service delivery, performance statistics, alarm statistics, configuration management, terminal function device upgrades, and terminal controller upgrades. The terminal function device is primarily responsible for the basic functions of the Ethernet passive optical network, such as registration, ranging, DBA, encryption, statistics, alarms, and line identification. The terminal controller is connected to any network port of the switch via an Ethernet interface, and the terminal function device is plugged into the switch via an optical module. The terminal controller and the terminal function device communicate via Layer 2 private Ethernet messages.

[0066] S2: Communicating and connecting the terminal controller and the terminal function device;

[0067] Exemplarily, the communication connection between the terminal controller and the terminal function device includes the steps of:

[0068] Determining whether the terminal controller has received a discovery request message sent by the terminal function device;

[0069] If so, the terminal controller sends a response request message to the terminal function device;

[0070] If not, the terminal function device sends a discovery request message to the outside world.

[0071] In this embodiment of the present application, after a terminal function device is plugged into a switch and powered on, it sends a discovery request message to the surrounding area via a broadcast mechanism. The terminal controller listens to a specific Ethernet broadcast address and receives the discovery request message. After receiving the discovery request message, the terminal controller sends a response request message, establishing a communication connection between the terminal function device and the terminal controller.

[0072] Exemplarily, the communication connection between the terminal controller and the terminal function device further includes the steps of:

[0073] Parsing the discovery request message;

[0074] Obtaining media access control address information in the discovery request message;

[0075] The terminal controller stores the media access control address information.

[0076] In the embodiment of the present application, the discovery request message includes the media access control address information of the terminal function device, and the terminal controller stores the media access control address information and is used to maintain the media access control address information of the terminal function device.

[0077] Exemplarily, the communication connection between the terminal controller and the terminal function device further includes the steps of:

[0078] Parsing the discovery request message;

[0079] Obtaining the sequence number information in the discovery request message;

[0080] The terminal controller stores the serial number information.

[0081] In the embodiment of the present application, the discovery request message includes the serial number information of the terminal function device, and the terminal controller stores the serial number information and uses it to maintain the serial number information of the terminal function device.

[0082] S3: assigning a logical serial number to the terminal function device;

[0083] Exemplarily, allocating a logical serial number to the terminal function device includes the steps of:

[0084] Obtaining media access control address information corresponding to the terminal function device;

[0085] Determining whether the terminal function device is online;

[0086] If so, determining whether the media access control address information includes a logical sequence number;

[0087] If not, return to the step of obtaining the media access control address information corresponding to the terminal function device;

[0088] If so, assigning the logical serial number to the terminal function device;

[0089] If not, a new logical sequence number is inserted and configured at the end of the media access control address information.

[0090] In the embodiments of the present application, a switch is equipped with multiple terminal function devices and a terminal controller to achieve flexible service configuration and expansion. Therefore, for multiple terminal function devices, there is a problem of how to configure a specific terminal function device so that the logical sequence of different terminal function devices plugged into the same network port remains unchanged regardless of the plugging and unplugging of the terminal function devices on the switch. At the same time, to facilitate maintenance personnel in locating the terminal function devices, a mapping relationship between the terminal function device and the switch port number must be established (this relationship is stored in a database) so that operation and maintenance personnel can clearly know which terminal function device on which switch needs to be operated.

[0091] Specifically, the terminal controller needs to record the association between the terminal function device and its media access control address information. When a terminal function device comes online, the terminal controller retrieves the mapping between the terminal function device and the switch port number from the database. If a logical sequence number is configured for a particular media access control address in the database, the terminal function device directly uses the pre-assigned logical sequence number. If a particular media access control address does not have a logical sequence number, a new media access control address is inserted at the end of the media access control address information in the database and assigned a corresponding logical sequence number.

[0092] S4: managing the communication process of the terminal function device;

[0093] Exemplarily, the process of managing the communication of the terminal function device includes the steps of:

[0094] Managing the session state of the terminal function device;

[0095] exchanging data between the terminal function device and the terminal controller;

[0096] Querying the communication status of the terminal function device;

[0097] Reporting performance data of the terminal function device.

[0098] In an embodiment of the present application, the terminal function device manages session status by using a heartbeat mechanism to periodically send heartbeat packets to maintain session activity. The terminal controller monitors these packets and promptly detects the terminal function device's session status. Data exchange between the terminal function device and the terminal controller is achieved by designing a standardized message communication interface for exchanging commands and data between the terminal controller and the terminal function device. The terminal function device's communication status is queried by the terminal controller, which queries the terminal function device's operating status, including port status and bandwidth utilization. Performance data reporting for the terminal function device is achieved by the terminal function device periodically reporting performance data, such as traffic statistics and latency, to the terminal controller.

[0099] S5: Reporting the alarm information of the terminal function device.

[0100] Exemplarily, the reporting of the alarm information of the terminal function device includes the steps of:

[0101] Get alarm events and their corresponding occurrence frequencies;

[0102] Determining whether the occurrence frequency exceeds a preset threshold;

[0103] If yes, report the alarm events in batches and regularly;

[0104] If not, report the alarm event.

[0105] In an embodiment of the present application, when a terminal function device detects an alarm event, it immediately sends an alarm message to the terminal controller. The message contains information such as the alarm address, level, type, timestamp, and detailed description. For alarm events that occur frequently (the frequency of occurrence exceeds a preset threshold), a batch periodic reporting mechanism can be adopted to regularly package and send alarm information to reduce network load. After receiving the alarm message, the terminal controller sends a confirmation message to the terminal function device to ensure that the alarm information is successfully received. If the alarm message is not confirmed, the terminal function device can resend it.
