Detailed Description
Fig. 1 is a schematic diagram of a network architecture, as shown in fig. 1, the network may be a PON, which may include: ONU01, enterprise gateway 02, base station 03, enhanced core switching node 04, switch 05, OLT06, etc. Wherein the base station may be an eNodeB, etc., without limitation.
Normally, the PON interface of the ONU is used as an upstream interface, that is, a network side interface, and an Ethernet (ETH) interface is used as a user side interface.
Generally, an ONU has one PON interface and multiple ETH interfaces, but the PON interface may be interrupted due to a link failure or other reasons, so that the ONU cannot interact with a network-side device.
The application provides a new network interface switching method of an optical network unit.
Fig. 2 is a schematic flowchart of a network interface switching method of an optical network unit according to an embodiment of the present application, where an execution main body of the method may be an ONU. As shown in fig. 1, the method includes:
s201, the ONU monitors the link state between the currently used network side interface and the target network equipment.
The currently used network-side interface refers to an interface currently used as an uplink interface to communicate with a destination network device. The destination network device is a network device in which the ONU performs communication through the uplink interface, and optionally, the network device may be an upper layer service device such as a video monitoring platform, but is not limited thereto.
The link status between the currently used network-side interface and the destination network device may be monitored in real time or periodically. The link status may reflect whether the link is normal.
S202, when the ONU determines to switch the currently used network side interface according to the link state, the ONU determines a target network side interface in at least one standby network side interface.
In an embodiment, the ONU may determine to switch the currently used network side interface when the link status indicates that the link between the network side interface and the destination network device is interrupted, or determine to switch the currently used network side interface when the currently used network side interface fails, or determine to switch the currently used network side interface when the previously detected failure is recovered to be normal.
If there are multiple backup network side interfaces, one of the backup network side interfaces can be determined as the target network side interface according to a preset rule. For example, when the standby network side interface includes the original PON interface, the original PON interface is preferentially selected as the target network side interface.
If the standby network side interfaces are all ETH interfaces, one of the standby network side interfaces can be randomly determined to be the target network side interface, or one of the ETH interfaces can be selected to be the target network side interface according to the pre-configured priority.
And S203, the ONU switches the currently used network side interface to the target network side interface.
And after the switching is finished, the link between the target network side interface and the target network equipment is communicated. Optionally, the uplink information may be transmitted through the target network side interface after the handover is completed.
Wherein, the currently used network side interface and the standby network side interface comprise: at least one original PON interface, and at least one original ETH interface pre-enabled to be a network side interface.
The original ETH interface is a user-side interface, where the original ETH interface that is pre-enabled as a network-side interface refers to configuring the original ETH interface to be usable as a network-side interface, and specifically may identify 1 or more pre-enabled as network-side interfaces in the multiple ETH interfaces, for example, identify a certain original ETH interface as a network-side interface through configuration parameters, which is not limited in this application.
That is, in the present application, one or more original ETH interfaces may be pre-enabled to be interfaces that can serve as network side interfaces, so that multiple interfaces may serve as network side interfaces, when one is used as a network side interface, the other serves as a standby network side interface, so that when the current network side interface needs to be switched, only one or more of the standby network side interfaces need to be selected for replacement. For example, when the original PON interface is used as the current network side interface, the other original ETH interfaces pre-enabled as the network side interfaces are standby network side interfaces, and when one of the original ETH interfaces pre-enabled as the network side interface is used as the current network side interface, the original PON interface and the remaining original ETH interfaces pre-enabled as the network side interfaces are used as the standby network side interfaces.
Of course, if a certain interface fails, it may be temporarily not used as a backup, and may be deleted or marked as another interface in the backup network side interface, etc., without limitation.
In this embodiment, the ONU monitors a link state between the currently used network side interface and the destination network device, determines a target network side interface in the at least one standby network side interface when determining to switch the currently used network side interface according to the link state, and switches the currently used network side interface to the target network side interface. One or more of the original ETH interfaces are enabled to be network side interfaces on the basis of the original PON interfaces, so that one or more standby network side interfaces can be directly switched when the current network side interfaces need to be switched, the reliability of ONU carrying service is improved, the hardware cost does not need to be increased, and networking is simpler and easier to realize. A new way of deploying a network-side interface is also provided, which makes the entire networking more flexible and volatile, in such a way that the ETH interface can be used as a network-side interface.
Optionally, the ONU processes and monitors a link state between the currently operating network side interface and the destination network device, and may also monitor a link state between the original PON interface and the destination network side device. For example, whether a link between the original PON interface and the target network side device is accessible is detected.
In a possible implementation manner, the optical network unit determines to switch the currently used network side interface according to the link state, where the ONU determines to switch the currently used original PON interface when the currently used network side interface is the original PON interface and the link state between the original PON interface and the destination network side device is disconnection.
Generally, the ONU may preferentially use the original PON interface, and during the use process, if the link state between the original PON interface in use and the destination network side device is disconnection, it is determined to switch the currently used original PON interface. It may also be that the original PON interface in use itself fails, and then the original PON interface currently in use is also switched.
In yet another possible implementation, when the ONU determines to switch the currently used network side interface according to the link state, the ONU determines the target network side interface among the at least one standby network side interface, where the ONU determines that the original PON interface is the target network side interface when the currently used network side interface is the original ETH interface and a link between the original PON interface and the target network side device is accessible.
That is, if there is an original PON interface that can be used normally in the standby network side interface, it is preferable to use the original PON interface. The implementation mode can improve the utilization rate of the interface, so that the original ETH interface can be continuously recovered as the user side interface, and more user side interfaces serve the user equipment.
In a specific implementation process, the ONU determines whether a link between the original PON interface and the destination network side device is accessible by detecting a link state between the original PON interface and the destination network side device. For example, the ONU sends a test message to the destination network side device through the original PON interface, and if the sending is successful, it may be considered that the link between the original PON interface and the destination network side device is accessible. If the transmission fails, it may be considered that a link between the original PON interface and the destination network side device fails or the failure has not been recovered.
One scenario may be that the originally used PON interface fails to switch to the standby network side interface (the original ETH interface that is pre-enabled as the network side interface). And the ONU continuously detects the state of the original PON interface, detects the failure removal, namely determines that a link between the original PON interface and the destination network side equipment is accessible, and then determines that the original PON interface is the destination network side interface. This continues to use the original PON interface as the network side interface.
Optionally, the ONU may periodically or in real time monitor the link state of the currently used network-side interface. In a specific implementation, the link state of the link connected to the currently used network side interface may be periodically or real-timely monitored after the uplink monitoring instruction is received, or the link state of the link connected to the currently used network side interface may be periodically or real-timely monitored after the network is connected, which is not limited herein.
Optionally, the method for detecting the link status may also be that a test message is sent to the destination network-side device through the currently used network-side interface, so as to determine whether the link between the currently used network-side interface and the destination network-side device is available.
For the case of receiving the uplink monitoring instruction, the ONU may obtain the uplink monitoring instruction before monitoring the link state of the current wan network side interface, where the uplink monitoring instruction is used to instruct to monitor the link state of the link connected to the currently used network side interface.
Specifically, there are various ways for the ONU to receive the uplink monitoring instruction, for example:
1) the ONU obtains an uplink monitoring instruction issued by the OLT through an Optical network Management and Control Interface (OMCI).
For example, the OLT may run an uplink monitoring command (an OLT command line or a Simple Network Management Protocol (SNMP) based command) that is issued to the ONU through the OMCI. However, the present invention is not limited to this, and other command methods may be used as the OLT is clouded.
2) And the ONU receives an uplink monitoring instruction sent by the network equipment.
Here, the network device may be a server, a network management device, or other network devices that can be directly connected to the ONU, and the network devices may send the uplink monitoring instruction through an in-band channel.
Alternatively, the uplink monitoring command may be transmitted through tr069 (Customer-Premises Equipment (CPE)) or an Extensible Markup Language (XML) file, but is not limited thereto.
3) And the ONU receives an uplink monitoring instruction issued by the OLT through a special channel.
Specifically, the OLT establishes a dedicated channel with the ONU, and then the OLT sends an uplink monitoring instruction to the ONU through the dedicated channel.
4) And the ONU acquires an uplink monitoring instruction input by a user.
Specifically, the ONU may provide an interface or button set by the user, and the uplink monitoring instruction is selected or input by the user.
Alternatively, the user may connect to the ONU setting interface through a network according to the address information of the ONU, for example, the user connects to the ONU setting interface through a web interface of a terminal (mobile phone, tablet, computer), and the like, and selects or inputs the uplink monitoring instruction on the ONU setting interface.
Of course, the ONU is not limited to the above example, and may obtain the uplink monitoring instruction in other manners.
Further, on the basis of the above embodiment, the method further includes: the ONU acquires standby network side interface configuration information, wherein the network side interface configuration information indicates at least one piece of information for specifying an original Ethernet interface. And the ONU enables the network side interface configuration information as the standby network side interface according to the standby network side interface configuration information. Optionally, the at least one piece of information specifying the original ethernet interface may be indicated by carrying at least one piece of identifier specifying the original ethernet interface in the network side interface configuration information.
It should be noted that, at least one specified original ethernet interface may be enabled as a standby network side interface in advance when the device is shipped from a factory, or the original ethernet interface indicated in the network side interface configuration information may be enabled as the standby network side interface after the network side interface configuration information is obtained. In the specific configuration process, parameters related to the configuration of the original ethernet interface indicated in the network side interface configuration information may be configured to open the uplink transmission channel of the specified original ethernet interface. For example, each original ethernet interface has an interface status identifier, and the value of the identifier reflects whether the ethernet interface is enabled to be a network side interface or a user side interface, for example, the status identifier "1" identifies the network side interface, and the status identifier "0" identifies the user side interface. Or, adding a state identifier to the original Ethernet interfaces which can be the network side interfaces, wherein other Ethernet interfaces which continue to be the user side interfaces have no state identifiers. Of course, the specific configuration is not limiting in this application.
The identifier of the original ethernet interface may be a number or an identification code of the ethernet interface.
Optionally, there are various ways for the ONU to obtain the configuration information of the standby network side interface, for example:
1) and the ONU acquires the network side interface configuration information issued by the OLT through the OMCI.
Specifically, the OLT executes a network side interface configuration instruction (OLT command line or SNMP-based instruction) to instruct configuration of one or more specified original ethernet interfaces, and then issues the instructions to the ONU through the OMCI. However, the present invention is not limited to this, and other command methods may be used as the OLT is clouded.
2) And the ONU receives the network side interface configuration information sent by the network equipment.
Here, the network device may be a server, a network management device, or other network devices that can be directly connected to the ONU, and the network devices may send the uplink monitoring instruction through an in-band channel.
Alternatively, the uplink monitoring instruction may be transmitted through the tr069 protocol or an XML file, but not limited thereto.
3) And the ONU receives the network side interface configuration information issued by the OLT through the special channel.
Specifically, the OLT establishes a dedicated channel with the ONU, and then the OLT sends network side interface configuration information to the ONU through the dedicated channel.
4) And the ONU acquires the network side interface configuration information input by the user.
Specifically, the ONU may provide an interface or a button set by the user, and the user selects or inputs the network-side interface configuration information.
Alternatively, the user may connect to the ONU setting interface through a network according to the address information of the ONU, for example, the user connects to the ONU setting interface through a web interface of a terminal (mobile phone, tablet, computer), and selects or inputs the network side interface configuration information on the ONU setting interface.
This approach is intuitive, for example: the user can directly select or input the ETH interface identification and the like which need to be configured on the interface.
Of course, the ONU is not limited to the above example, and the ONU may configure the information on the network side interface in another manner.
Further, in some cases, the ETH interface pre-enabled as the network-side interface may also be restored as the user-side interface, that is, used for downlink interaction with the user-side device, and the like. For example, one or more ETH interfaces pre-enabled as network-side interfaces may be restored as user-side interfaces when the user-side interfaces are not sufficient or when the user-side interfaces fail. Or after the original PON interface is restored to normal, the original PON interface is switched to a network side interface, and then one or more ETH interfaces pre-enabled as network side interfaces may also be restored to user side interfaces. So that more user-side interfaces serve the user equipment.
Specifically, the ONU obtains spare network side interface cancellation information, where the network side interface cancellation information indicates information of at least one original ethernet interface that is pre-enabled as the network side interface. And the ONU restores the at least one original Ethernet interface which is pre-enabled as the network side interface into the user side interface according to the network side interface cancellation information. The recovered ethernet interface is no longer used as the network side interface, but the ONU may pre-enable the ethernet interface to be the network side interface according to the configuration information of the network side interface in the case of subsequent needs.
It should be noted that the network side interface cancellation information may carry one or more identifiers of ETH interfaces that are pre-enabled as network side interfaces.
Corresponding to the aforementioned enabling of at least one designated original ethernet interface as the standby network-side interface, when the user-side interface is restored, the state identifier of the interface may be changed, for example, the state identifier "1" identifies the network-side interface, and the state identifier "0" identifies the user-side interface, and then the state identifier is changed from 1 to 0. Or deleting the state identifier when only the network side interface has the state identifier. The present application is not particularly limited.
Optionally, the ONU obtains the cancellation information of the standby network side interface, and there may be multiple ways, for example:
1) and the ONU acquires the network side interface cancellation information issued by the OLT through the OMCI.
Optionally, the OLT executes a network side interface cancellation instruction (OLT command line or SNMP based instruction) to instruct to restore one or more original ethernet interfaces that have been pre-enabled as network side interfaces, and then issues the ethernet interfaces to the ONUs through the OMCI. However, the present invention is not limited to this, and other command methods may be used as the OLT is clouded.
2) And the ONU receives the network side interface cancellation information sent by the network equipment.
Here, the network device may be a server, a network management device, or other network devices that can be directly connected to the ONU, and the network devices may send the uplink monitoring instruction through an in-band channel.
Alternatively, the uplink monitoring instruction may be transmitted through the tr069 protocol or an XML file, but not limited thereto.
3) And the ONU receives the network side interface cancellation information issued by the OLT through the special channel.
Specifically, the OLT establishes a dedicated channel with the ONU, and then the OLT sends network side interface cancellation information to the ONU through the dedicated channel.
4) And the ONU acquires the network side interface cancellation information input by the user.
Specifically, the ONU may provide an interface or a button set by the user, and the user selects or inputs the network-side interface cancellation information.
