Description

Method and device for matching home gateway feature code under optical network unit

The present invention relates to the field of EPON (Ethernet Passive Optical Networks) technology, and in particular, to a method and device for matching a home gateway feature code under an optical network unit. Background technique

The network architecture of the 无源 (passive optical network) system is shown in Figure 1. It mainly includes: OLT (Optical Line Terminal), ODN (Optical Distribution Network), and ONU (Optical Network Unit). Optical network unit) three parts, connected by ODN between OLT and OJ.

In the FTTH (fiber-to-home) mode of the main application, the ONU directly connects the Home Gateway (HG) to implement related services, and the ONU and the OLT use the extended OAM (operation, management, and maintenance) to interact. The NMS uses SNMP (Simple Network Management Protocol) to manage the OLT.

The application scenario of the home gateway (HG) under the optical network unit (O J ) is shown in Figure 2. The main requirements are as follows:

1. The HG signature code (MAC address) can be accurately matched after the ONU is connected. When the HG is connected to the network, if the signature is not within the specified range, the network management system matches the HG signature when the HG accesses the network. Whether it is within the specified range, if not, reject the HG access network;

2. When the port connected to the HG on the ONU is replaced with a PC, the PC is required to be able to access the Internet normally.

3. When the port connected to the HG on the ONU is replaced with a PC and then replaced with the HG again, the HG must be used normally.

In principle, the switching between the PC and the HG also needs to support the feature code that accurately matches the HG. However, it is considered that: First, all HG signature codes of the entire network cannot be saved on the ONU; Second, the ONU needs to be able to quickly switch configurations, and the message is not suitable. Reported to the network management for accurate judgment; In addition, the MAC address of the PC and The mask of the HG may be the same after the mask processing. In this case, when the PC and the HG are switched, the PC may be mistaken for HG, so that the configuration data cannot be switched normally. Summary of the invention

Embodiments of the present invention provide a method and device for matching a home gateway feature code of an optical network unit, which effectively solves some problems of data configuration switching when PC and HG are switched.

A method for matching a home gateway feature code of an optical network unit according to an embodiment of the present invention includes:

After the home gateway (HG) connected to the optical network unit (ONU) is successfully connected to the network, the ONU registers the medium access control (MAC) address of the HG as an HG signature;

When the ONU detects the access device, if the MAC address of the access device is consistent with the registered HG signature, the access device is identified as an HG.

Preferably, the method further includes:

After the ONU identifies that the access device is an HG, it determines whether the home gateway network access flag is an incoming network, and if not, reports the home gateway network access information to the network management device, and receives the home gateway reply from the network management system. After the network identification message is confirmed, the home gateway network access flag is set as the network access.

Preferably, the O U reports the home gateway network information to the network management system as follows:

ONU data port number, the HG MAC address, Data Vlan, IPTV Vlan. VoIP Vlan information.

Preferably, the method further includes:

After the HG is successfully connected to the network, the HG is performed on the network management system after the new HG is replaced. After the new HG is successfully accessed, the OJ updates the registered HG signature to the new HG. MAC address.

Preferably, when the ONU detects the access device, if the MAC address of the access device does not match the HG signature registered in the ONU, the access device is identified as a PC.

Preferably, the MAC address of the access device and the HG signature code registered by the ONU If the current data is the configuration of the PC scene, the current data is configured in the HG mode.

Preferably, when the MAC address of the access device is inconsistent with the HG signature code registered by the ONU, it is determined whether the current data is a configuration of an HG scenario or a configuration of a PC scenario. If the current data is a configuration of an HG scenario, Switch to the configuration of the PC mode.

An embodiment of the present invention further provides a feature code matching device, where the device is applied to an ONU, where the device includes a device discovery module and a management module, where:

The management module is configured to register the HG MAC address as an HG signature after the HG connected to the ONU is successfully connected to the network;

The device discovery module is configured to report the MAC address of the access device to the management module when the access device is detected.

Preferably, the management module is configured to determine whether the MAC address of the access device is consistent with the registered HG signature when receiving the MAC address of the access device reported by the device discovery module. If they are consistent, the access device is identified as an HG; if not, the access device is identified as a PC.

Preferably, the management module is configured to: after determining that the access device is an HG, determine whether the home gateway network access flag is an incoming network, and if not, report the home gateway network access information to the network management, and receive the information After the home gateway replies the home gateway identity confirmation message, the home gateway network access flag is set as the network access.

If the MAC address of the access device is inconsistent with the registered HG feature code, it is determined whether the current data is the configuration of the HG scenario or the configuration of the PC scenario. If the current data is the configuration of the HG scenario, the configuration is switched to the PC mode. .

With the solution of the embodiment of the present invention, the following two functions can be supported in the HG scenario of the ONU: The normal access network of the HG can accurately switch the configuration data when the PC and the HG are switched. Drawing fan

The embodiment provides a method for matching a home gateway feature code of an optical network unit, and adopts the following technical solution:

The ONU provides the function of registering the current HG signature. After the HG is successfully connected to the network, the OU device records the current HG signature to the Flash, and the ONU restart signature is not lost; thus, the registered HG signature pair can be verified. Access device for identification.

When the home gateway connected to the ONU is powered on or connected to the PC, the port of the OJ will be changed from the down state to the UP state. The OJ first determines whether the HG is configured on the ONU according to the HG network access indication on the ONU. Then, the HG is sent to the EMS (Element Management System); if the HG is configured in the OU, the current connection is determined based on whether the MAC address of the current access device and the HG signature registered on the OMJ are consistent. Whether the incoming device is HG or PC, if the MAC address and the registered HG feature code are the same, it indicates that it is HG, otherwise it is processed according to the PC.

According to the above process, the HG can be supported to support the random switching between the PC and the HG. After the HG is connected to the network, if you need to replace the new HG, you need to perform the HG operation on the U2000, and then re-enter the new HG. Update the MAC signature registration on the ONU after the HG accesses the network successfully. Then, when the PC and HG are switched, the related MAC address registration is performed to perform related judgment and processing.

The implementation of the technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the features in the embodiments and the embodiments of the present application may be arbitrarily combined with each other without conflict.

The HG signature matching process in the embodiment of the present invention is shown in FIG. 3, and the specific description is as follows: 1. HG network access procedure

After Stepl.ONU is connected to the network (the home gateway Mac address pool and the home gateway network management system Vlan are configured), the ONU automatically recognizes the home gateway information according to the home gateway Mac address pool and the network management VLAN configuration. The Mac address learned through the ONU data port matches Vlan and Mac for identification.

After the home gateway is identified, the ONU sends the home gateway network information to the NMS through the extended oam alarm mode. At the same time, the ONU needs to save the home gateway network access flag. When the ONU recognizes the home gateway, it is necessary to confirm whether the home gateway information needs to be reported according to the network access flag. If the home gateway is connected to the network, it does not need to be reported again. It is processed according to the HG and PC switching process. If the home gateway fails to report the network access or reports the network access failure (the network management system does not receive the confirmation message), it needs to be reported. The reported information includes the ONU data port number, home gateway Mac, Data Vlan, IPTV Vlan, and VoIP Vlan information.

Step3. The network management replies to the home gateway to confirm the message. After receiving the network gateway confirmation message, the ONU changes the home gateway network access status flag on the ONU to the network and saves it to the flash.

If the ONU does not receive the confirmation message from the network management system within the set time period (for example, it can be set to 3 minutes), the process returns to Step2. The ONU needs to re-report the home gateway network access information.

In addition, the OLT needs to configure the vlan mode of the ONU port.

Second, HG and PC switching process

1) When the ONU device discovery module finds that there is an address change, a message will be sent to the management module. The management module processes the changes based on the MAC address. ONU judges according to the locally saved network logo The broken HG has already entered the network, and there is no need to report the home gateway information.

2) Obtain the MAC address of the connected device, and compare the MAC address set by the host with the HG signature code registered by the ONU to check whether it is the HG device that was previously connected to the network.

If the MAC address of the connected device is the same as the HG signature of the ONU, the current data is configured as the HG scenario. If the current data is in the HG scenario, the configuration data does not need to be switched. If the current data is the configuration of the PC scenario, you need to switch to the HG configuration and then complete the process.

4) If the MAC address of the connected device is inconsistent with the HG feature code registered on the ONU, determine whether the current data is the configuration of the PC scenario: If the current data is configured in the PC scenario, the configuration data switching operation is not required, and the process is completed. If the current data is the configuration of the HG scene, you need to switch to the PC mode configuration, and then complete the process.

The HG teardown process of the embodiment of the present invention is shown in FIG. 4, and the steps are as follows:

a) The NMS sends the home gateway teardown command. Configure the data port of the ONU as Tag mode and PVID=Data Vlan.

b) The network management sends the home gateway network management Vlan configuration to the MJ. The OLT needs to configure all the ONU data ports in the translation mode (or other modes as required), default vlan=Data Vlan, mapping entries: Home Gateway Network Management Vlan<->Home Gateway Network Management Vlan.

c) The network gateway sends the home gateway network access flag to the unconnected network. After receiving the home network access network ID delivered by the NMS, the ONU changes the home gateway network access status flag on the ONU to the unconnected network and saves it to the flash.

In addition, a feature code matching device is also provided in the embodiment of the present invention. The device is applied to the O U. As shown in FIG. 5, the device discovery module 50 and the management module 51 are included, where:

The management module 51 is configured to register the HG MAC address as an HG signature after the HG connected to the ONU is successfully connected to the network;

The device discovery module 50 is configured to report the MAC address of the access device to the management module when the access device is detected.

The management module 51 may be further configured to receive the connection reported by the device discovery module. When the MAC address of the device is entered, it is determined whether the MAC address of the access device is consistent with the registered HG signature. If they are consistent, the access device is identified as an HG; if not, the device is identified. The access device is a PC.

The management module 51 may be further configured to: after determining that the access device is an HG, determine whether the home gateway network access identifier is an incoming network, and if not, report the home gateway network access information to the network management device, and receive the information After the home gateway receives the network identity confirmation message, the home gateway network access flag is set as the network access.

The management module 51 may be further configured to: when the new HG is replaced, update the registered HG signature to the new HG MAC address after the new HG is successfully accessed.

The management module 51 may be further configured to determine, when the MAC address of the access device is consistent with the registered HG feature code, whether the current data is a configuration of an HG scenario or a configuration of a PC scenario, if the current data is a PC scenario. Configure the switch to the HG configuration.

If the MAC address of the access device is inconsistent with the registered HG feature code, it is determined whether the current data is the configuration of the HG scenario or the configuration of the PC scenario. If the current data is the configuration of the HG scenario, the configuration is switched to the PC mode.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. The present invention may be embodied in various other embodiments without departing from the spirit and scope of the invention. Various changes and modifications may be made to the invention, and such changes and modifications are intended to be included within the scope of the appended claims.
