Under the prior art, the configured synchronization needs to be sent by a communication system in a unit of configuration of a single PON or ONU, and after the opposite OLT receives the configuration, the configuration message needs to be parsed and sent to the ONU or PON. A maximum of 128 ONUs are connected to one PON port, a maximum of 16 PON ports are provided in one OLT, and in an extreme case, the configuration may be transmitted thousands of times, so that high-frequency synchronization is not likely to have a risk of losing the configuration, the configuration may be changed accidentally in the transmission process, and analyzing data and issuing the configuration may also bring a great burden to the CPU at the opposite end.

IGMP Profile: multicast-related configuration;
format Profile: and (5) format configuration.
Still further, the OLT of the active configuration protection group is used as a master device, and the configured OLT is used as a slave device;
when the protection group is established, two conditions need to be satisfied:
condition 1: any template does not exist in the master device, so that collision with the slave device is prevented;
condition 2: the PON added to the protection group in the master device and the slave device has no template already bound;

Detailed Description
The invention is described in detail below with reference to the drawings and the detailed description.
Example 1
Under the traditional technology, configuration synchronization can only take a single PON or ONU as a unit, and the configuration is transmitted one by one to achieve the synchronization effect. For example, tcont of an ONU needs to be configured, and after the ONU under the PON of the main OLT configures parameters of tcont, these parameters need to be transferred to the slave OLT through the communication system, analyzed, and then sent to the slave PON. If there are 128 ONUs under a PON, the configuration of tcont needs to be passed 128 times.
In order to ensure and enhance the reliability and efficiency of configuration synchronization, under the condition of supporting the original method of configuration synchronization, the embodiment also provides a method for automatic synchronization configuration of dual-homing PON protection, namely, configuration synchronization is performed by using a configuration template, and the method comprises the following steps:
s1: and after the two butted OLTs simultaneously start the dual-homing PON protection function, a protection group is established according to the template binding condition.
In a specific embodiment, the OLT of the active configuration protection group is used as a master device, and the configured OLT is used as a slave device;
when the protection group is established, two conditions need to be satisfied:
condition 1: any template does not exist in the master device, so that collision with the slave device is prevented;
condition 2: the PON added to the protection group in the master device and the slave device has no template already bound;
when the conditions are met, a protection group is established, and the master device and the slave device establish a TCP/IP communication link for message delivery.
In the specific flow of step S1 in this embodiment, as shown in fig. 2,
s101: the master device and the slave device are powered on, and the dual-homing PON protection function is opened.
S102: the method comprises the steps that a master device configures a protection group, a user inputs an ip address of a slave device and a matched PON port, and clicks and submits the ip address and the matched PON port; the master device first checks whether a template exists or not, if so, immediately returns and displays the configuration failure, and if not, step S103 is executed.
S103: the master device then attempts to connect to the slave device; the slave device receives the connection request, analyzes the message and acquires a PON port needing to be added into a protection group, checks whether the PON port is bound with a template, and if so, returns a message of refusing to build the group to the master device, and the master device displays the failure of configuration; if not, the slave device adds the protection group locally and returns successful group establishment to the master device.
S104: the master device receives the set-up success message and adds the protection group on its own, thereby completing the set-up of the protection group.
S2: establishing an ID unique template on any one OLT, synchronizing to an opposite terminal OLT through a communication system and establishing an ID unique template, wherein the two OLTs are provided with templates with the same ID; and completing the template configuration and synchronization of the two OLTs.
In a specific embodiment, step S2, when the OLT at the opposite end receives the newly created template information, it is checked whether the OLT at the opposite end has a template with the same ID, and if so, the synchronization template is rejected; if not, a template with the same ID and content is established on the terminal OLT. The specific flow of step S2 is shown in fig. 3.
In this embodiment, when the protection group is set, the configuration setting performed at any OLT is synchronized to another OLT.
However, since the slave device may have an old template, when any OLT device adds a new template, it will first query whether the opposite OLT device has a template with the same ID, and if so, it is not allowed to use the ID for template addition.
S3: binding a template on any OLT to a PON port in a protection group, and if the PON port belongs to a certain dual-homing protection group, transmitting an ID of the template to an opposite terminal OLT by the OLT; and the opposite terminal OLT binds the templates with the same ID according to the received ID, thereby completing template binding of PON ports in the protection group, and the template binding flow is shown in figure 4.
In a specific embodiment, step S3, when the opposite OLT receives a binding template request, it first checks whether there is a template with the same ID on the opposite OLT, and if so, binds; if the template does not exist, binding failure information is returned to the opposite side, and the opposite side does not bind the template to the PON port after receiving the failure information.
In this embodiment, after the template is set, the template can be bound to the PON port in the protection group, only one OLT needs to be operated at this time, and the ID of the template is transmitted to another OLT via the network, so that the PON port at the opposite end is also bound to the template with the same ID (i.e., the same content).
However, since the slave device may have an old template, when the PON port binding template in the group is protected, whether the template exists on the OLT should be queried first, and if not, the binding fails.
S4: when an ONU located on any OLT registers, extracting configuration from a template of the OLT and issuing the configuration to the ONU through an OMCI, or extracting configuration from the template of the OLT and modifying an OMCI stack of the ONU; and synchronously registering information to the opposite terminal OLT to finish the registration of the opposite terminal ONU.
In this embodiment, if the ONU is deleted, the ONU at the opposite end will be deleted at this time, and the ONU may read the configuration from the template on the OLT when re-registering.
In this embodiment, the procedure flow of ONU registration is shown in fig. 5.
S401: the ONU is online on the main equipment OLT and synchronously registers information to the slave equipment OLT;
s402: and the PON ports on the two OLT sides respectively check whether binding templates exist, and if so, the PON ports extract the configuration from the templates of the OLT and issue the configuration to the ONU through the OMCI or modify the OMCI stack of the ONU.
In a specific embodiment, the template is a configuration format, which includes various service configurations of the ONU, and the applicable object is a PON port or an ONU.
In a specific embodiment, the configurable templates include the following:
ONU Profile is basic information of ONU, critical range;
DBA Profile: dynamic bandwidth allocation;
traffic Profile: browsing configuration;
line Profile: line configuration;
service Profile: service configuration;
alarm Profile: alarm configuration;
pri Profile: private OMCI configuration;
IGMP Profile: multicast-related configuration;
format Profile: and (5) format configuration.
In a specific embodiment, when an ONU located on any OLT is deleted, the deletion information is synchronized to the opposite end, and the ONU on the opposite end is deleted correspondingly; when re-registering, the ONUs may read the configuration from the templates on the respective OLTs.
In a specific embodiment, after the protection group is established, the configured templates are automatically synchronized to the OLTs at the two ends and stored; when a new PON port is added to a new protection group, if the same template is used, only the ID of the synchronization template is needed, and the configuration of the same content is not needed to be sent to the opposite OLT.
In this embodiment, the PON port of the binding template issues the same configuration to the downstream ONU according to the content in the format.
The template is used for being bound on a PON port, and when the ONU is registered on the PON port, the ONU and the PON can be directly issued by using the configuration set on the template, so that the aim of configuring the PON and the ONU is fulfilled. Different templates are distinguished using IDs, in this embodiment, one ID for each template.
After a protection group is established between the two OLTs, the newly-built templates at any one end can be automatically synchronized to the other end. When the PON port of one OLT binds a specific template, the template ID is also sent to the opposite PON port, so that the opposite PON port binds a template having the same ID. At this time, when the ONU is on line at the PON port of the master, the PON port of the slave will register the same ONU registration information in synchronization with the PON port of the master, but the configuration information does not need to be synchronized by the communication system, and it is only necessary to read the configuration information from the templates on the respective OLTs based on the bound IDs.
The template synchronizing method can reduce the number of times of configuration synchronization and the size of the total content in the dual-homing PON protection. And the configuration is taken from the OLT, so that the possibility that the error configuration which is accidentally modified in the transmission process is issued to the PON and the ONU can be reduced, and the reliability of the service is enhanced.
Example 2
Based on the method for automatic synchronization configuration of dual-homing PON protection described in embodiment 1, in this embodiment, for the purpose of a specific practical example, the configuration of the protection group and the template described in this embodiment may be configured in a command line and a web page, and the following examples are configured in a web page as examples.
In each of the drawings described below, the left boundary surface is the master OLT and the right boundary surface is the slave OLT.
First, turning on a switch of dual-homing PON protection of two OLT apparatuses, as shown in fig. 6;
in the second step, a protection group is configured, in this example, the master OLT uses PON5, the slave OLT uses PON8, inputs IP addresses of the two OLTs, clicks sub, and adds a protection group. After addition, there is information of corresponding protection groups on the interface of the two devices, as shown in fig. 7.
Thirdly, a template is configured, taking a Line Profile configuration as an example. As can be seen from fig. 8, there is no Line Profile on the master OLT, but there is one (ID 1) on the slave OLT, and at this time, if the Line Profile with ID 1 is added to the master OLT, an error is reported (as shown in fig. 9). Therefore, a template with an ID of 2 and named as "example_line_profile" is added to the main device OLT, as shown in fig. 10, both sides have a Line Profile with an ID of 2, the Line Profile is edited, taking a configuration Tcont as an example, and a configuration is synchronized to another section, as shown in fig. 11.
Fourth, the PON port binding template, as shown in fig. 12, is bound by the OLT at one end, and the OLT at the other end is bound by the same template.
Fifth, the ONU registers on-line, and after the ONU goes on-line, the PON takes the configuration from the bound template and issues it to the ONU (only Tcont in this example). After registration is online, information of the ONUs exists on both sides, the ONUs on the main PON port are displayed as an online state, the ONUs on the opposite-end PON port are in an offline state (fig. 13), the configuration of the ONUs is checked by clicking, tcont on both sides is found to be configured (fig. 14), and the configuration of the ONUs is completed synchronously.
