Detailed Description

In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Example 1

The ONU device of the present embodiment includes a housing and a controller mounted within the housing. The shell is provided with communication ports and is provided with port lamps for each port, such as a user side electric port or a user side optical port serving as a user network interface UNI, see figure 2, two ONU devices with the same model m, wherein the upper ONU which has been registered on the target OLT at the target installation position is defined as old ONU device, the lower ONU is defined as new ONU device, the old ONU device and the new ONU device are connected and communicated through the communication ports of each other according to the connection operation of a user, and specifically, the two ONU devices are connected with the communication ports of each other through network cables respectively so as to realize the information interaction of the two ONU devices based on local connection. The ONU equipment shell is also provided with a physical switch (such as a key) connected with the controller to control the on/off of the copy replacement function. In other embodiments, the physical switch may be changed to control the on/off of the copy replacement function in an external button form or in a WEB/TELNET/CLI manner, or may be changed to be automatically triggered when the old ONU device recognizes that the preset communication port receives a communication request from the same type communication port of the new ONU device. When the ONU malfunctions or needs to replace the ONU devices for other reasons, an administrator or a user connects the old ONU devices and the new ONU devices with the same model with the network line as WAN ports of the communication ports, then presses the physical switches of the old ONU devices and the new ONU devices respectively, and the processors of the two devices execute the pre-stored program for realizing the copy replacement function, so as to identify the preset selection operation of the user on the old ONU devices and the new ONU devices, and complete the quick copy replacement based on the local connection by the local connection quick copy replacement method of the ONU of the embodiment shown in fig. 1.

The local connection quick copying replacement method of the ONU of the present embodiment specifically connects and communicates an old ONU device and a new ONU device through communication ports of each other, and then one of the old ONU device and the new ONU device initiates a replacement request, and the other one receives the replacement request. If the initiation and the reception are successful, the old ONU equipment transmits the replacement information to the new ONU equipment through the communication port after backing up the replacement information, the replacement information comprises the MAC address of the old ONU equipment, the new ONU equipment receives the replacement information through the communication port, the information of the corresponding position of the new ONU equipment is overwritten with the content of the replacement information, and the old ONU equipment changes the MAC address in the replacement information, so that the new ONU equipment copies and replaces the old ONU equipment. And all lamps continuously flash after the copying and replacing are completed by the two ONU devices until the ONU is automatically restarted. After the new ONU equipment and the old ONU equipment are mutually replaced, the identities of the new ONU equipment and the old ONU equipment are exchanged, the identities and the configuration information of the new ONU equipment are not changed, the new ONU equipment completely replaces the old ONU equipment after the new ONU equipment is accessed to the existing network, the connected OLT also does not sense the old ONU equipment, namely, the replacement is successful, and the OLT considers the original ONU after the OLT is connected, so that the method is convenient and quick.

The originating terminal of this embodiment is an old ONU device. In addition, the old ONU device and the new ONU device can be initiated and received instead, and the old ONU device and the new ONU device are not distinguished, and both backup their own replacement information, for example, the replacement information is stored in a local flash or other storage devices, so that the information rollback processing is performed after the copy replacement process fails. Then, the self-replacement information is sent to the opposite side and the replacement information sent by the opposite side is received, so that each ONU device does not need to distinguish whether the ONU device is the old ONU device needing replacement or the new ONU device newly installed, and misoperation is avoided.

Wherein, the old ONU device changing the MAC address in the replacement information means: the old ONU equipment changes the MAC address of the new ONU equipment or the old ONU equipment writes the MAC address in the non-replacement information so as to avoid the conflict between the two ONU equipment when communicating to the OLT.

Wherein the replacement information further includes basic device information and basic configuration information. The basic device information is ONU registration identification information, including device physical identification information such as GPON SN, and account information such as LOID/PASSWORD, and the MAC address may be included in the basic device information. The basic configuration information comprises local configuration information of ONU equipment of the model or private management message issuing information defined by manufacturers, namely independent service configuration information, such as WAN configuration, WLAN configuration, voice configuration, multicast configuration and the like, and the independent service configuration information of ONU equipment of different models of different brands is not identical.

If the initiation or the reception fails, for example, one or both of the old ONU equipment and the new ONU equipment do not support the function, one or both of the information interaction fails, or the other or both of the two fails to set the information of the other party locally, the two ONUs can perform information rollback processing so as to recover the original information of each ONU. At this time, the port lamps of the two ONU devices are always on, and after 10 seconds, both ONUs are automatically restarted.

And if any information content exchange in the basic equipment information and the basic configuration information fails, the ONU equipment information exchange is considered to fail. In addition, the replacement information further includes extended configuration information, and if only the extended configuration information fails to exchange, the ONU device is not considered to fail to exchange information. The extended service configuration information is configuration information which can be issued by the ONU through an OAM/OMCI message of the OLT.

The local connection quick replication replacement method of the ONU of this embodiment has different configuration information requirements under the EPON network architecture and under the GPON network architecture.

Configuration information under the EPON network architecture is as follows: configuring user side interface parameters, such as opening/closing of a user side interface, opening/closing of a Pause flow control, and configuration of Ethernet/ADSL2+/VDSL 2 interfaces (rate, noise margin and the like) of MDU and MTU ONU; configuring QoS functions of the service, such as classification, queuing, marking, scheduling and the like of the uplink service, and configuring functions of queuing, scheduling, speed limiting and the like of the downlink service; configuration of DBA parameters, such as the number of Queue sets and reporting threshold of each Queue; configuring Ethernet functions such as VLAN, frame filtering, multicast, MAC address aging time and the like; configuring PON interface functions such as optical fiber protection switching and the like; ACL configuration function of ONU; local software/firmware upgrades.

The configuration information under the GPON network architecture is as follows: configuration of ONU logic identification authentication; the user side interface parameters are configured, such as the opening/closing of a user side interface, the opening/closing of a Pause flow control, the configuration of Ethernet/ADSL2+/VDSL 2 interfaces (rate, noise margin and the like) of MDU and MTU ONU; configuring QoS functions of the service, such as classification, queuing, marking, scheduling and the like of the uplink service, and configuring functions of queuing, scheduling, speed limiting and the like of the downlink service; configuration of DBA parameters; configuring Ethernet functions such as VLAN, frame filtering, multicast, MAC address aging time and the like; configuring PON interface functions such as optical fiber protection switching and the like; ACL configuration function of ONU; local software/firmware upgrades.

When one of the new and old ONU equipment is an EPON network architecture and the other is a GPON network architecture, if the preset replacement information of the old ONU equipment can be covered by the new ONU equipment, see FIG. 4, the ONU equipment information interaction of the new ONU equipment can be successfully received, so that the old ONU equipment can be replaced by the new ONU equipment, and the replacement information of the old ONU equipment can be manually recorded or rewritten.

According to the local connection quick copying and replacing method of the ONU, communication ports on the new ONU equipment and the old ONU equipment are connected through the network cable so that the new ONU equipment and the old ONU equipment can communicate, the new ONU equipment can exchange basic equipment information and basic configuration information through a local communication mode, the new ONU equipment receives the replacement information through the communication port so as to overwrite information of corresponding positions of the new ONU equipment, particularly, the old ONU equipment also changes basic equipment information such as original MAC addresses and the like which can cause equipment conflict, so that the new ONU equipment can copy and replace the old ONU equipment, the whole copying and replacing process is realized by only manually opening physical switches on the two ONU equipment, and the transmission of account information, configuration information and data is realized by a preset program without manual operation, so that the method is quick and convenient, and manual operation is simplified.
