In a conventional Optical Network Unit (ONU) upgrade, an Optical Line Terminal (OLT) generally downloads an upgrade file of the ONU from an FTP server, and then an OAM (Operation Administration and Maintenance) message or an OMCI (ONU Management and Control Interface) message issued by the OLT transmits the upgrade file to the ONU. The upgrading mode needs to establish network layer connection among all devices, and the transmission rate of OAM and OMIC is low, which affects upgrading efficiency.

In order to overcome the above problems, embodiments of the present application provide an optical network unit upgrade system. As shown in fig. 1, the optical network unit upgrading system includes: anupgrade server 10, anoptical line terminal 20, and anoptical network unit 30.

The number of theoptical network units 30 is greater than or equal to 1, and 3optical network units 30 are illustrated as an example in fig. 1, but the number of theoptical network units 30 is not limited. Theupgrade server 10 may be a PC computer or other intelligent terminal. Optionally, when theupgrade server 10 has multiple network cards, one of the network cards is designated as an upgrade data transmission network card for decompressing the upgrade file in the designated path. It should be noted that the operating system of theupgrade server 10 may be a Windows operating system or a Linux operating system.

Theupgrade server 10 is communicatively connected to theoptical line terminal 20, and eachoptical network unit 30 is communicatively connected to theoptical line terminal 20.

Theupgrade server 10 is configured to send an upgrade data packet to theolt 20 through an ethernet frame, where the upgrade data packet carries an identifier of a target to be upgraded, and the identifier of the target to be upgraded corresponds to a unique identifier of theonu 30 to be upgraded. The unique identifier may be a MAC address.

Optionally, the upgrade data package is a configuration information upgrade data package or a software version upgrade data package.

Theoptical line terminal 20 is configured to send the upgrade data packet to theoptical network unit 30 to be upgraded via an ethernet frame.

The onu to be upgraded 30 is configured to activate an upgrade packet to complete the upgrade of the onu.

Optionally, on a production line of the ONU, when a large number of ONUs whose firmware has been programmed need to update software versions before shipment, the initial installation of ONU software is implemented by using an FTP server, compared with the conventional technique. The FTP server must be guaranteed to be connected to the network layer of the ONU, and in order to guarantee the network layer connection, network configuration needs to be performed on the ONU of the HGU (Home Gateway Unit), and the configured contents include but are not limited to: IP and VLAN. When the number of configurations is large, the configuration process takes a lot of time. In the embodiment of the application, the Ethernet frames are used for communication, and the ONU does not need to be configured in a network, so that the configuration time is saved, and the production efficiency is improved.

Optionally, currently, the commonly used ONUs are divided into a GPON ONU and an EPON ONU according to a protocol, and the GPON ONU and the EPON ONU follow different standard upgrading protocols, and need to correspond to different OLTs (the GPON ONU corresponds to the GPON OLT, and the EPON ONU corresponds to the EPON OLT), and different tool upgrading commands are used to upgrade the ONUs. In the embodiment of the application, the software upgrading of the GPON ONU and the GEPON ONU is realized uniformly by adopting the same tool upgrading process. And under the condition that the ONU is upgraded without using the FTP server, the TCP protocol of a network layer is not involved, so that the network attack related to the TCP protocol can be avoided, and the safety in the upgrading process is improved.

Optionally, in the conventional technology, only tens of bytes can be transmitted at most every second by downloading the upgrade image through the OMCI message or the OAM message, and the rate is slow. And the speed of downloading the upgrade image is not lower than 1Mbps and can reach 100Mbps at most by transmitting the upgrade data packet through the Ethernet frame. And only 30 seconds are needed for upgrading the ONU with the mirror image size of 30M, so that the transmission speed is greatly improved.

To sum up, an embodiment of the present application provides an optical network unit upgrading system, which includes: the system comprises an upgrading server, an optical line terminal and an optical network unit; the upgrading server is used for sending an upgrading data packet to the optical line terminal through an Ethernet frame, wherein the upgrading data packet carries a target identifier to be upgraded, and the target identifier to be upgraded corresponds to the unique identifier of the optical network unit to be upgraded; the optical line terminal is used for sending the upgrading data packet to the optical network unit to be upgraded through the Ethernet frame; and the optical network unit to be upgraded is used for activating the upgrade data packet so as to complete the upgrade of the optical network unit. Because the upgrade data packet is transmitted through the Ethernet frame, compared with the traditional upgrade scheme, the ONU does not need to be subjected to network configuration, so that the configuration time is saved, and the production efficiency is improved; the software upgrading of the ONUs with different specifications is realized uniformly by adopting the same tool upgrading process without involving a TCP (transmission control protocol) protocol of a network layer, so that network attacks related to the TCP protocol can be avoided, and the safety in the upgrading process is improved; and the transmission speed is greatly improved.

Optionally, regarding the format of the ethernet frame, the embodiment of the present application further provides a possible implementation manner, please refer to the following table.

The destination MAC is a unique identifier of theoptical network unit 30 to be upgraded in the downlink direction, for example: 01-80-c2-00-00-e0; the upstream direction is the unique identifier (MAC) of theupgrade server 10; and (3) source MAC: in the downstream direction is the unique identifier (MAC) of theupgrade server 10; the uplink direction is the unique identifier of the onu to be upgraded 30; the Ethernet type: 0x1234; the command identification bit is used for indicating the type of the interactive frame between theupgrade server 10 and theoptical network unit 30; the object is full FF or ONU MAC in the downlink direction, and is the MAC of the ONU sending the data frame in the uplink direction; the protocol data unit length represents the length of the following protocol data unit; the protocol data unit represents a load.

Optionally, the embodiment of the present application also provides a possible implementation manner on how to determine theoptical network unit 30 to be upgraded. Referring to fig. 2, fig. 2 is a schematic diagram of signaling interaction provided in an embodiment of the present application.

Before theupgrade server 10 sends the upgrade data packet to theolt 20 via the ethernet frame, theupgrade server 10 clears the first-generation to-be-upgraded list of the information of the last updated ONU.

Theupgrade server 10 is further configured to send an auto discovery frame to theoptical line terminal 20, where the auto discovery frame carries an identifier of a target to be discovered.

Alternatively, the target identifier may be a full FF address matching all network units in the system, or may be a MAC address of a certain optical network unit. Theupgrade server 10 transmits one auto discovery frame per second, and may set the maximum number of times of transmitting the auto discovery frame to three times by default.

Optionally, the auto discovery frame sent by theupgrade server 10 is configured, for example, a destination MAC of the auto discovery frame, an ethernet type, and the like are configured. The purpose of sending the automatic discovery frame is to obtain basic information of all or a designated ONU, and can also be used for testing whether the network is clear, wherein the basic information of the ONU includes but is not limited to the current version information of the ONU. For example, when the destination MAC in the auto discovery frame is set to the MAC of the designated ONU, it indicates that theupgrade server 10 desires to obtain basic information of the ONU of the designated MAC. When the destination MAC in the auto-discovery frame is set to the full FF address (FF: FF), it indicates that theupgrade server 10 wishes to obtain basic information of all ONUs.

Compared with the prior art that each ONU reports the information of the ONU actively, the upgradingserver 10 sends an automatic discovery frame to detect the ONU which meets the preset conditions, and the problem that the upgrading strategy is inflexible when the OLT is used for upgrading is solved.

Theoptical line terminal 20 is further configured to issue an auto discovery frame to eachoptical network unit 30.

Theupgrade server 10 adds a unique identifier in an auto discovery response frame whose current version is a version to be upgraded to the list to be upgraded of the first generation.

Possibly, all versions that are not the latest are upgraded, or only some specified versions are upgraded.

Theupgrade server 10 is further configured to send an upgrade request frame to theoptical line terminal 20, where the upgrade request frame includes basic information of an optical network unit corresponding to the unique identifier in the first-generation list to be upgraded.

Theoptical line terminal 20 is further configured to send the upgrade request frame to eachoptical network unit 30.

If the difference is not the same, discarding the data and not responding.

Theoptical line terminal 20 is further configured to send an upgrade request response frame to theupgrade server 10;

theupgrade server 10 is further configured to delete the unique identifier of theoptical network unit 30 that does not feed back the upgrade request response frame from the first-generation list to be upgraded.

The success rate of upgrading is further ensured by secondarily confirming whether theoptical network unit 30 to be upgraded is in a communicable state.

Theupgrade server 10 is further configured to use the unique identifier of the first generation list to be upgraded as an identifier of the target to be upgraded, and generate an upgrade data packet.

Optionally, as to how to further ensure the correctness of the upgrade object selection, the embodiment of the present application also provides a possible implementation manner, please continue to refer to fig. 2.

Theupgrade server 10 is further configured to transmit an upgrade file information frame to theoptical network unit 30 through theoptical line terminal 20, where the upgrade file information frame includes a size attribute, a version attribute, and a verification attribute of the upgrade data packet. Optionally, the check attribute is a check result obtained by performing CRC32 check.

Theoptical network unit 30 is further configured to determine whether the upgrade data is applicable according to the size attribute, the version attribute, and the check attribute of the upgrade data packet; and if the update file information response frame is applicable, feeding back the update file information response frame to theupdate server 10, wherein the update file information response frame contains the unique identifier of theoptical network unit 30. The upgrade file information response frame indicates that the attribute verification of the upgrade data packet by theonu 30 is successful and applicable.

When the upgrade file version is not right, and the upgrade file is too large or too small, it indicates that the upgrade data packet is not suitable, theonu 30 is further configured to return a response frame of the failed upgrade file information or do no feedback, and does not participate in the subsequent steps.

Theupgrade server 10 is further configured to delete the unique identifier of theoptical network unit 30 that does not feed back the upgrade file information response frame from the first-generation list to be upgraded.
