Description
Technical Field
The invention relates to the technical field of communication, in particular to a method for realizing automatic configuration of a service VLAN to an ONU (optical network unit) by a GPON (gigabit Passive optical network) system.
Background
In the existing GPON OLT system, there are two ways to implement configuring ONU services: one is to manually configure a single ONU, and the other is to automatically configure a single or a plurality of ONUs by a template. The automatic configuration of the service after ONU registration is online is realized by configuring each service template, and different ONUs using the same service template are configured with one or more service VLANs by the OLT. As disclosed in chinese patent publication No.: CN1901464A, published: 2007-01-24 discloses an EPON network element equipment automatic configuration method, which comprises the following steps: the following data is stored on the OLT of the EPON: default configuration data, network management configuration data and current configuration data; when the OLT is initialized, the OLT and the ONU are configured by using OLT-level default configuration data, and the default configuration data is copied as network management configuration data and current configuration data after the configuration is successful; the user can configure the OLT or the ONU from the network management according to the actual requirement and issue the relevant configuration data; when the OLT is reset or deactivated, the current configuration data of the OLT level and all ONU levels on the OLT are cleared; when the OLT is reset or reactivated after deactivation, configuring the OLT by using OLT-level configuration data in network management configuration data; after the ONU is successfully registered, configuring the ONU by using ONU-level configuration data in network management configuration data; and after the ONU is unregistered, clearing the current configuration data of the ONU level.
The limitation of the automatic configuration of the ONU service by the GPON OLT in the existing scheme is that a service VLAN cannot be flexibly configured to the ONU, and all ONUs bound and configured by the same template are configured with the same service VLAN or service VLANs, so that the automatic batch operation of allocating a different service VLAN to each ONU cannot be realized. The invention solves the limitation of the existing scheme by designing and realizing the variable function of the VLAN, and achieves the purposes of avoiding the trouble of manual single configuration and configuring different service VLANs for each ONU.
Disclosure of Invention
In order to solve the defects and shortcomings of the prior art, the invention provides a method for realizing the automatic configuration of a service VLAN to an ONU by a GPON system, which can avoid the trouble of manual single configuration and can configure different service VLANs for each ONU.
In order to achieve the purpose of the invention, the technical scheme is as follows:
a method for realizing GPON system to configure service VLAN to ONU automatically includes following steps:
s1: when the OLT equipment is powered on and initialized, initializing a VLAN variable function and acquiring a VLAN variable initial value;
s2: judging whether to start a VLAN variable function according to a VLAN variable initial value, and if the VLAN variable function is started, starting automatic registration functions of all PON ports at the same time;
s3: when receiving a message of ONU registration online, calling an ONU online processing function to check whether a PON port where the ONU registered online is located starts a VLAN variable function;
s4: verifying whether a VLAN variable function is started or not by acquiring a value of a global variable, and calculating a current service VLAN value of the ONU according to the ID of a PON port of the ONU and the ID of the ONU after the VLAN variable function is started;
s5: and carrying out validity check on the service VLAN value, and if the validity check is passed, configuring the service VLAN to the ONU equipment by the OLT equipment.
Preferably, the OLT device stores status data of the VLAN variable function in a flash memory;
when the OLT equipment enters initialization, firstly reading whether state data of a VLAN variable function in a flash memory exists or not, if not, establishing and writing 00000000, wherein the first 4 bytes are used as a VLAN variable initial value, and the last 4 bytes are used as an extended voice VLAN function;
and storing the VLAN variable initial value in a global variable, traversing the global linked list of all PON port nodes, updating and storing the VLAN variable initial value, and updating the global variable and VLAN variable zone bits of all PON port nodes.
Further, whether to start the VLAN variable function is determined according to the VLAN variable start value, which is specifically as follows: if the VLAN variable initial value is equal to 0, the VLAN variable function is closed; if the VLAN variable initial value is larger than 0, the VLAN variable function is started.
Still further, a CPU in the OLT apparatus creates a first message queue for sending a message, creates a first thread, and creates a receive message queue for receiving a status message of the ONU apparatus in the first thread; the state information comprises ONU registration on-line information, off-line information and alarm information;
when the receiving message queue receives the message of the ONU registering on line, executing the step S3; and if the VLAN variable function is started, sending a VLAN variable message by using the first message queue, and returning to continuously wait for receiving the status message of the ONU equipment after the sending is finished or the VLAN variable function is not started.
Still further, the first thread acquires the content of the received message queue every 1 s.
Still further, the CPU in the OLT apparatus further creates a second thread for processing a common service task, and creates a second message queue in the second thread; the second message queue is used for receiving messages with variable VLAN; when the second message queue receives the message of which the VLAN is variable, steps S4, S5 are performed.
And further, reporting the VLAN variable message to a CPU in the OLT equipment through the ONU registration on-line message, and distinguishing the VLAN variable message from the ONU registration on-line message by adopting a message parameter type.
Still further, the calculation formula for calculating the service VLAN value of the ONU is as follows:
variable_vlan＝vv_feature+128×(onuInfo.pon-1)+(onuInfo.onu-1)
here, variable _ VLAN represents a service VLAN value of an ONU, vv _ feature represents a VLAN variable start value, onuinfo.
And further, if the calculated service VLAN value is between 1 and 4094, the service VLAN value is legal and passes the validity check, otherwise, the service VLAN value does not pass the validity check.
A GPON system comprises an OLT, an ODN and a plurality of ONUs; the OLT is in communication connection with the plurality of ONUs through the ODN; and the OLT executes the method for realizing the automatic configuration of the service VLAN to the ONU by the GPON system and configures the service VLAN to the ONU.
The invention has the following beneficial effects:
by the method for realizing the automatic configuration of the service VLAN to the ONU by the GPON system, the GPON OLT system can flexibly configure the ONU service VLAN in batches without being limited by a template, which is different from a single VLAN with a plug-and-play function, and the ONU is also not configured one by one.
The invention is suitable for configuring the ONU in batch, and each ONU has a service VLAN different from other ONUs. In the above scenario, if a service VLAN is manually configured for each ONU, the time used is about 20s, and assuming that there are 8 PON ports, each PON port is full of 128 ONUs, and the time required for configuring all ONUs is about 5.69h, which is 20480s, which is 8 × 128 × 20 s. The invention can save the time of the manual configuration and complete the automatic service configuration after the ONU is on line. Therefore, the more the number of the ONUs to be configured is, the better the effect brought by the method is, and the more comprehensive and friendly user experience can be brought to the user of the GPON OLT.

In this embodiment, when configuring the VLAN variable start value, the global variable g _ vv _ feature for storing the VLAN variable start value is also updated accordingly. The VLAN variable initial value is a service VLAN numerical value corresponding to a first ONU of a first PON.
If the VLAN variable function is switched from off to on, the OLT needs to ensure that each PON port turns on the ONU automatic registration function, and each PON port is used to turn on the VLAN variable function (some PON ports can be supported to turn on or off the VLAN variable function individually), so that the VLAN variable flag bits of all PON port nodes need to be updated.
S2: judging whether to start the VLAN variable function according to the VLAN variable initial value, if the configured VLAN variable initial value is equal to 0, the VLAN variable function is closed; if the configured VLAN variable initial value is larger than 0, the VLAN variable function is started, and the automatic registration function of all PON ports is started.
S3: when the OLT equipment is powered on and the system is initialized, a CPU in the OLT equipment creates a first message queue MSG _ send _ queue [ VS _ MSG _ FLAG ] for sending messages, then creates a first thread, and creates a receiving message queue MSG _ send _ queue [ VS _ MSG _ FLAG ] for receiving status messages of the ONU equipment in the first thread; the state information comprises ONU registration on-line information, off-line information and alarm information;
when a message queue receives a message of ONU registration online, calling an ONU online processing function to check whether a PON port where the ONU registered online is located starts a VLAN variable function;
if the VLAN variable function is started, the VLAN variable message is sent by using a first message queue MSG _ send _ queue [ VS _ MSG _ FLAG ], and the state message of continuously waiting for receiving the ONU equipment is returned after the sending is finished or the VLAN variable function is not started. Wherein the first thread obtains the contents of the received message queue every 1 s.
S4: when the OLT equipment is powered on and the system is initialized, the CPU in the OLT equipment also creates a second thread sspDRvComService for processing a public service task, and a second message queue comMsgQueue is created in the second thread; the second message queue is used for receiving messages with variable VLAN; when the second message queue comMsgQueue receives the VLAN variable message, firstly, whether the VLAN variable function is started or not is verified by acquiring the value of the global variable, and the current service VLAN value of the ONU is calculated according to the ID of the PON port of the ONU and the ID of the ONU after the VLAN variable function is started;
s5: and meanwhile, carrying out validity check on the service VLAN value in the second message queue comMsgQueue, if the calculated service VLAN value is between 1 and 4094, the service VLAN value is legal, and if the validity check is passed, the OLT equipment configures the service VLAN to the ONU equipment, otherwise, the service VLAN does not pass. And if the configuration of the service VLAN is completed or abnormality and ineligibility occur in the process of configuring the service VLAN, returning to the waiting receiving state of the received message queue.
In a specific embodiment, the VLAN-variable message is reported to a CPU in the OLT device through a message that the ONU registers to be on-line, and the VLAN-variable message and the message that the ONU registers to be on-line are distinguished by using a message parameter type.
In a specific embodiment, the calculation formula for calculating the service VLAN value of the ONU is as follows:
variable_vlan＝vv_feature+128×(onuInfo.pon-1)+(onuInfo.onu-1)
here, variable _ VLAN represents a service VLAN value of an ONU, vv _ feature represents a VLAN variable start value, onuinfo.
The specific operation is as follows: VLAN variable function the user interface in the GPON OLT system has a command line CLI and a Web page Web.
In the command line CLI interface, the global configuration command operation specification is as shown in table 1:
TABLE 1
The operation command in the PON port mode is shown in table 2:
TABLE 2
In a Web page Web interface, in an ONU AutoLearn menu, selecting a Variable Vlan drop-down box, enabling to select 'Enable', and inputting a Variable initial value in a text box, wherein the default value is 1; disable selects the "Disable" option.
Based on the PON port, under the condition that the VLAN variable function is enabled, the enabling/disabling configuration of the VLAN variable function of the PON port can appear in a WEB page, and an 'Enable' option corresponds to the enabling of the selected PON port; the "disable" option is reversed.
The variable initial value of the operational Web page Web configuration VLAN in this embodiment is 20.
