Description

A method for fully configuring a virtual local area network of an optical network unit

technical field

The invention belongs to the network field, and in particular relates to a method for fully configuring a virtual local area network (Virtual Local Area Network, vlan) of an optical network unit (Optical Network Unit, ONU).

Background technique

In an Ethernet Passive Optical Network (EPON) system, a management terminal ONU is configured through an optical line terminal (Optical Line Terminal, OLT) at the central office. For the registered ONU, the management staff will configure and manage the ONU through the OLT to realize the user's business needs. The virtual local area network mode configuration of the ONU is one of its indispensable configurations. With the development of fiber-to-the-home broadband access and the development of triple network integration, multiple user access unit (Multiple Dwelling Unit, MDU) devices have been widely used Among them, it caters to the development needs of multi-user broadband access.

When the vlan mode of a 24-port EPON MDU device is configured as full configuration, the OLT will send a large number of Operation Administration and Maintenance (OAM) messages to the ONU, and the ONU will analyze them after receiving the messages. message content to process and make a response to the OLT. For example: 24 ports of ONU are all configured as trunk mode, each port can be configured with 17 vlans (including a default vlan), and 24 ports can be configured with 17*24=408 vlans. MDU type ONU software adopts ECOS real-time operating system, multi-thread programming, OAM message processing in thread EPON. The implementation of vlan mode is relatively complicated. The user interface is based on port configuration, and the driver interface is based on vlan, which is the overall situation for the internal switching chip. The conversion from the user interface data structure to the driver interface data structure has more complex logic, especially when there are already a large number of vlans, adding another vlan configuration will take a long time for the central processing unit (CPU) to process . If the OLT sends the configuration data too quickly, it will wait for a longer time for the ONU to reply to the OLT. If the configuration is delivered, the previous configuration will not be delivered, resulting in failure to restore the configuration of the ONU.

Contents of the invention

The technical problem to be solved by the present invention is to provide a method for fully configuring a virtual local area network of an optical network unit. The problem of configuration failure occurs.

The present invention is realized in this way, a kind of virtual local area network full allocation method of optical network unit, it comprises the following steps: carry out management configuration to ONU by OLT, send a large amount of vlan configuration data, this vlan configuration data passes EPON protocol stack to EPON thread, the EPON thread performs extended OAM analysis processing, and includes the configuration of the vlan mode; the EPON thread receives the OAM message for analysis, and determines whether it is vlan configuration data; if it is vlan configuration data, then store the vlan configuration data; the EPON thread sends a vlan processing message to the vlan message queue; and the EPON thread replies a normal OAM message to the EPON protocol stack.

Compared with the prior art, the present invention has the beneficial effects that: the full configuration method of the virtual local area network of the optical network unit of the present invention can ensure that the OAM message carrying a large amount of vlan data issued by the OLT can be replied in time, and the OAM reply due to the ONU can be avoided. The timeout causes the OLT to think that the configuration has failed.

Description of drawings

FIG. 1 is a flow chart of a method for full configuration of a virtual local area network of an optical network unit provided by an embodiment of the present invention.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

As shown in Figure 1, the method for the virtual local area network of the optical network unit provided by the embodiment of the present invention is fully configured, for the MDU ONU efficiently and quickly responds to the configuration request message sent by the OLT (also does not carry the ONU vlan fully configured data ), and it does not affect the EPON efficiency of the ONU receiving core thread. This method handles the flow by changing the vlan. Create a thread configured in vlan mode, and add a message queue mechanism for EPON threads to notify the vlan processing thread to complete the configuration of vlan mode. Since EPON threads share memory, using the message queue mechanism is the best choice for synchronization between EPON threads and VLAN processing threads. In addition, the thread scheduling policy of embedded configurable operating system (ECOS system) should be set to preemptive , threads with higher priority are executed first. Set the priority of the vlan processing thread to be lower than the core thread EPON. In this way, most of the processing flow of vlan is handed over to the vlan processing thread for processing. Thus, the EPON thread can reply the OAM to the OLT in time, avoiding the problem that the OLT considers the configuration to be a failure due to the timeout of the configuration reply.

The method for fully configuring the virtual local area network of the optical network unit includes the following steps:

S1: The ONU is managed and configured through the OLT, and a large amount of vlan configuration data is delivered. The vlan configuration data passes through the EPON protocol stack to the EPON thread. The EPON thread mainly performs the analysis and processing of the extended OAM, including the configuration of the vlan mode.

S2: The EPON thread receives the OAM message, analyzes it, and determines whether it is vlan configuration data.

S3: If no data is configured for the vlan, then end.

S4: If it is vlan configuration data, store the vlan configuration data.

S5: The EPON thread sends the vlan processing message to the vlan message queue. The vlan processing message includes the storage address of the vlan configuration data, and the vlan processing thread reads the vlan configuration data according to the storage address.

S6: The EPON thread replies a normal OAM message to the EPON protocol stack, and then quickly responds to the configuration request of the OLT, avoiding reply timeout.

S7: the vlan processing thread polls the message queue in the running state to determine whether there is vlan configuration data to be processed.

S8: if there is no vlan configuration data to be processed, then end.

S9: If there is vlan configuration data to be processed, the vlan processing thread reads the vlan configuration data to process the vlan software table.

S10: the vlan processing thread sends the vlan software table to the hardware table, and finally completes the configuration processing of a large number of vlans.

Compared with the prior art, the method for fully configuring the virtual local area network of the optical network unit of the present invention will modify the processing flow of the MDU type vlan data, create a message queue to store the vlan configuration data, and then create a vlan processing thread. The priority of the vlan processing thread is lower than that of the core thread EPON. After this, the EPON thread parses out the vlan configuration data in time, saves it in the vlan message queue, and replies the OAM message to the OLT. Vlan configuration is processed in the vlan processing thread. This not only improves the core, but also does not waste the resources of the core process. It not only ensures the stability and high efficiency of the core thread, but also ensures that the OAM message carrying a large amount of vlan data sent by the OLT is answered in time, and the OLT is prevented from being caused by the ONU reply timeout. Issues that consider configuration failures.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
