[0029] The features and exemplary embodiments of various aspects of the present application will be described in detail below. To make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0030] It should be noted that in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, elements defined by the statement "comprising..." do not preclude the existence of additional identical elements in the process, method, article or device comprising the elements.

[0031] Before elaborating on the technical solutions provided in the embodiments of the present application, for the convenience of understanding the embodiments of the present application, the present application first specifically describes the problems existing in the related technologies:

[0032] Currently, the broadband access network corresponding to the user equipment is as Figure 1 shown, as Figure 1The exemplary broadband access network provided includes an OLT device 101, a primary BRAS device 102, and a standby BRAS device 103. Usually, based on the Virtual Router Redundancy Protocol (VRRP), the broadband access network provides broadband services for user equipment through the primary BRAS device 102. When the primary BRAS device 102 is disconnected from the OLT device 101, the standby BRAS device 103 provides broadband services for user equipment. However, in the case where the standby BRAS device is also disconnected from the OLT device, the user equipment will be unable to use broadband services, resulting in a poor user experience.

[0033] Based on this, the embodiments of the present application provide a method, system, device, equipment, medium, and product for switching communication ports, which can solve the above problems.

[0034] Next, a system for switching communication ports provided by the embodiments of the present application will be described in detail.

[0035] In some embodiments, as Figure 2 shown, the embodiments of the present application provide a system for switching communication ports. The above system may include:

[0036] A first BRAS device 2011 and a second BRAS device 2012. The first BRAS device and the second BRAS device are used to provide broadband services for user equipment. The first BRAS device 2011 is a standby device for providing broadband services for user equipment, and the second BRAS device 2012 is a primary device for providing broadband services for user equipment;

[0037] An OLT device 202. The OLT device 202 may include a first port 2021, a second port 2022, and a third port 2023. Among them, the OLT device is connected to the first BRAS device 2011 through the first port 2021, the OLT device is connected to the second BRAS device 2012 through the second port 2022, and the OLT device 202 is connected to a routing switch device through the third port 2023. The OLT device 202 is used to obtain the state of the first port 2021 of the OLT device 202. When the state of the first port 2021 is a closed state, the state of the third port 2023 is modified to a start state, so that the target BRAS device provides broadband services for user equipment based on the communication link composed of the router device, the routing switch device, and the OLT device;

[0038] A router device 203, which is used to communicate with the target BRAS device and the routing switch device. The target BRAS device includes the first BRAS device or the second BRAS device;

[0039] A routing switch device 204 for communicating with a router device 203 and an OLT device 201.

[0040] In some embodiments, as Figure 2 shown, the above OLT device may further include a fourth port 2024. When the state of the second port 2022 changes to closed, the OLT device 202 may change the state of the fourth port 2024 from the closed state to the start state. When the OLT device determines that the state of the fourth port 2024 is the start state and the state of the first port 2021 is the closed state, it may change the state of the third port 2023 to the start state, so as to ensure that when the states of both the first port 2021 and the second port 2022 are the closed state, the third port 2023 is started to provide broadband services for the user device based on the communication link composed of the router device, the routing switch device, and the OLT device, and improve the accuracy of changing the state of the third port 2023.

[0041] In some embodiments, when the OLT device later detects that the state of the first port 2021 or the second port 2022 is the start state, it may change the state of the third port 2023 to the closed state, so that the first BRAS device or the second BRAS device provides broadband services for the user device.

[0042] By providing a system for switching communication ports including the above first BRAS device, second BRAS device, OLT device, router device, and routing switch device in the embodiments of the present application, when both the first BRAS device and the second BRAS device are disconnected from the OLT device, the BRAS device can provide broadband services for the user device based on the communication link composed of the router device, the routing switch device, and the OLT device, enabling the user to continuously use broadband services. Moreover, the above communication link does not need to be configured on the user device side, and the communication link can be switched without the user's awareness, improving the user experience.

[0043] In some embodiments, as Figure 3 described, the embodiments of the present application provide a method for switching communication ports, which is applied to an optical line terminal OLT device. The OLT device includes a first port, a second port, and a third port. The OLT device is connected to a first BRAS device through the first port, connected to a second BRAS device through the second port, and connected to a routing switch device through the third port. The first BRAS device is a standby device for providing broadband services to the user device, and the second BRAS device is a primary device for providing broadband services to the user device. The method includes:

[0044] S310: Obtain the state of the first port of the OLT device.

[0045] Here, the status of the first port of the OLT device can be obtained. The status of the first port can include the connection status and communication status of the port. For example, the connection status can be the physical status of the port, and the communication status can be the protocol status of the port.

[0046] S320: When the status of the first port is the closed state, modify the status of the third port to the start state, so that the target BRAS device provides broadband services for the user device based on the communication link composed of the router device, the routing switch device, and the OLT device. Wherein, when the status of the first port is the closed state, the status of the second port is the closed state, and the target BRAS device includes the first BRAS device or the second BRAS device.

[0047] It can be conceived that under normal circumstances, the statuses of the first port and the second port are both in the start state. However, due to the setting of the VRRP protocol, broadband services will only be provided for the user device through the second BRAS device. When the status of the second port is the closed state, broadband services will be provided for the user device through the first BRAS device. When it is detected that the status of the first port is the closed state, the status of the third port can be modified to the start state. For example, the communication status of the third port can be changed from down to up. Here, when the status of the first port is the closed state, it can include that the connection status of the first port is down or the communication status is down.

[0048] In some examples, when it is determined that the statuses of both the first port and the second port are the closed state, the status of the third port can be modified to the start state.

[0049] In some examples, the above-mentioned routing switch device and router device can connect to the same local area network in response to the configuration information input by the user. For example, they can connect to the same Virtual Local Area Network (VLAN) to enable communication between the routing switch device and the router device.

[0050] In some examples, the above-mentioned routing switch device is a device that can convert a wired signal into a wireless signal, enabling the routing switch device to communicate with the router device and enabling the user device such as an Optical Network Unit (ONU) to be unaware when switching the communication link.

[0051] In the embodiments of the present application, by obtaining the status of the first port connected to the first BRAS device, when the status of the first port is in a closed state, the status of the third port connected to the routing switch device is modified to a startup state, so that when the standby BRAS device is disconnected from the OLT device, the user device can perform traffic data transmission based on the transmission link composed of the OLT device - routing switch device - router device - BRAS device, enabling the user device to maintain the use of broadband services, improving the user experience, and no configuration is required on the user device side when setting and switching the above communication link, achieving user imperceptibility.

[0052] It can be conceived that to ensure the accuracy of modifying the status of the third port, the status of the third port can be modified when it is determined that the statuses of the first port and the second port are both in a closed state.

[0053] In some embodiments, the OLT device further includes a fourth port, wherein the OLT device is connected to the routing switch device through the fourth port; when the status of the first port is in a closed state, modifying the status of the third port to a startup state includes:

[0054] Obtaining the status of the fourth port, wherein the status of the fourth port is determined based on the status of the second port; when the status of the fourth port includes a startup state and the status of the first port includes a closed state, modifying the status of the third port to a startup state.

[0055] In some examples, the communication link through which the OLT device is connected to the first BRAS device through the first port can be the first link, the communication link through which the OLT device is connected to the second BRAS device through the second port can be the second link, the communication link through which the target BRAS device is based on the router device, routing switch device, and OLT device can be the third link, and the link through which the OLT device is connected to the routing switch device through the fourth port is the fourth link. The first link and the third link can be set as the first link aggregation group, and at the same time, the second link and the fourth link can be set as the second link aggregation group. The above one link aggregation group can be aggregated through the link aggregation protocol (such as E-TRUNK), and the maximum number of surviving links in one link aggregation group is set to 1.

[0056] When the status of the second port becomes a closed state, the status of the fourth port will be modified from a closed state to a startup state, and it is set that only when the status of the fourth port is in a startup state and the status of the first port is in a closed state, the status of the third port can be modified from a closed state to a startup state, so that the BRAS device provides broadband services for the user device based on the third link. Here, the startup state of the fourth port can include that the communication status of the fourth port changes from down to up.

[0057] In the embodiments of the present application, by setting the fourth port as the indication port for determining whether the second port is closed and jointly forming the control port for whether the third port is started with the first port, it is possible to start the third port when ensuring that the states of the first port and the second port are both closed, improving the accuracy of modifying the state of the third port.

[0058] It can be conceived that when the state of the third port is the started state, the states of the first port and the second port can be continuously monitored, and when it is determined that any one of the ports becomes the started state, the state of the third port can be promptly modified to the closed state to cut off the third link, so that the BRAS device provides broadband services for the user device based on the first link or the second link.

[0059] In some embodiments, as Figure 4 shown, after step S320 modifies the state of the third port to the started state, the method further includes:

[0060] S410: Obtain the state of the target port, where the target port is the first port or the second port.

[0061] The state of the first port or the second port can be obtained.

[0062] S420: When the state of the target port is the started state, modify the state of the third port to the closed state.

[0063] When the state of the target port is the started state, it indicates that the BRAS device corresponding to the target port resumes communication with the OLT device. The state of the third port can be modified to the closed state, so that the BRAS device provides broadband services for the user device based on the aforementioned first link or the second link.

[0064] For example, when it is determined that both the connection state and the communication state of the target port are up, the communication state of the third port is modified to down.

[0065] When the embodiments of the present application detect that the state of the target port is the started state, the state of the third port is promptly modified to the closed state, so that the BRAS device provides broadband services for the user device through the link directly connected to the OLT device, which can improve the quality of broadband services provided for the user device, enhance the user experience, and the above link switching also does not need to be configured on the user side, realizing user imperceptibility.

[0066] In some embodiments, modifying the state of the second port to the closed state includes:

[0067] When the target port includes the second port, modify the state of the fourth port to the closed state to modify the state of the third port to the closed state.

[0068] Here, when the above-mentioned target port is the second port, that is, when the state of the second port changes to the startup state, the state of the fourth port can be modified to the closed state. When the state of the fourth port is the closed state, the state of the third port will be modified to the closed state. Here, the communication state of the fourth port can be directly modified to down, and the communication state of the third port will be modified to down.

[0069] In some embodiments, the third port includes a first sub-port and a second sub-port. The first sub-port is used to transmit user service data, and the second sub-port is used to transmit device management data.

[0070] The above-mentioned first sub-port is used to transmit user service data at the second layer of the link, and the above-mentioned second sub-port is used to transmit device management data at the third layer of the link. The above-mentioned user service data is traffic data generated by users using broadband services, and the above-mentioned device management data is traffic data generated for managing OLT devices.

[0071] It can be set that the third port includes a first sub-port and a second sub-port. Here, the OLT device can transmit user service data to the routing switch device based on the above-mentioned first sub-port, and the OLT device can transmit device management data based on the second sub-port, so that the routing switch device transmits the above-mentioned user service data and device management data to the routing device, so that the routing device transmits the above-mentioned user service data and device management data to the BRAS device, so that the BRAS device manages the user service data and device management data.

[0072] By setting the first sub-port and the second sub-port to transmit user service data and device management data respectively in the embodiments of the present application, it is convenient for the BRAS device to manage the above-mentioned data later, and the communication security is improved.

[0073] In some embodiments, as Figure 5 shown, the embodiments of the present application provide a device for switching communication ports, which is applied to an OLT device. The OLT device includes a first port, a second port and a third port. Among them, the OLT device is connected to a first BRAS device through the first port, the OLT device is connected to a second BRAS device through the second port, and the OLT device is connected to a routing switch device through the third port. The first BRAS device is a standby device for providing broadband services to user devices, and the second BRAS device is a primary device for providing broadband services to user devices. The device includes:

[0074] An acquisition module 501, configured to acquire the state of the first port of the OLT device;

[0075] A status modification module 502 is configured to modify the status of a third port to a startup status when the status of a first port is in a closed state, so that a target BRAS device provides broadband services for a user device based on a communication link composed of a router device, a routing switch device, and an OLT device. Wherein, when the status of the first port is in a closed state, the status of a second port is in a closed state, and the target BRAS includes a first BRAS device or a second BRAS device.

[0076] In some embodiments, the OLT device further includes a fourth port, wherein the OLT device is connected to the routing switch device through the fourth port; specifically, the status modification module may be configured to:

[0077] Obtain the status of the fourth port, where the status of the fourth port is determined based on the status of the second port;

[0078] When the status of the fourth port includes a startup status and the status of the first port includes a closed state, modify the status of the third port to a startup status.

[0079] In some embodiments, the obtaining module may further be configured to:

[0080] Obtain the status of a target port, where the target port is the first port or the second port;

[0081] When the status of the target port is in a startup state, modify the status of the third port to a closed state.

[0082] In some embodiments, the status modification module may further be configured to:

[0083] When the target port includes the second port, modify the status of the fourth port to a closed state, so as to modify the status of the third port to a closed state.

[0084] In some embodiments, the traffic data includes user service data and device management data; the third port includes a first sub-port and a second sub-port, the first sub-port is used to transmit user service data, and the second sub-port is used to transmit device management data.
