Problems solved by technology

[0011] The technical problem to be solved by the present invention is to provide a MIB data upload method and GPON in order to overcome the defects of low upload efficiency, easy occurrence of data transmission errors and easy generation of a large amount of invalid data in ONU / ONT attribute upload of the prior art. Network, by marking valid upload attributes and determining the length of attributes to improve upload efficiency, in addition, by generating a copy of attributes in the MIB at any time, thereby avoiding errors in uploaded data and generation of invalid data

[0042] In this embodiment, the number of the maximum valid attributes in the MIB of an ONT in the GPON network is counted, that is, the number of attributes of the ONT that can be used by the OLT is confirmed. And correspondingly determine the data length of the effective attributes of each ONT that needs to be uploaded to the OLT, so that the ONT can encapsulate the effective attributes of each required injury into a message. Therefore, the message in this embodiment has different message lengths according to the data length of the effective attributes. Therefore, the previous fixed reporting method of each attribute is changed to improve the accuracy and efficiency of MIB reporting.

[0043] Therefore, in this embodiment, a mark AttrMask indicating whether the attribute is a valid attribute of the attribute required by the OLT is added to the attribute in the MIB, and the valid data length Len of the attribute is further marked in each valid attribute.

[0044] After that, using ...

[0057] The difference between the MIB data upload method of this embodiment and the MIB data upload method of the first embodiment is that, in this embodiment, after the ONU receives the request message sent by the OLT, it generates all attributes of the MIB at that moment. Copy, that is, import all the attribute data in the MIB at that moment into a cache, so even if the attributes in the MIB change due to the configuration or function changes in the ONU, it will not change the attribute data uploaded by the ONU to the OLT. Avoid uploading data errors and invalid data.

[0058] Therefore, the MIB data upload method of this embodiment is as follows figure 2 As shown, including the following steps:

[0059] Step 11. The OLT sends an OMCI request message to an ONU.

[0060] Step 12: The ONU determines the preset upload attribute type based on the OMCI request message.

[0061] Step 13: Write all attributes of the current MIB of the ONU into a buffer. At this time, the ONU can write ...

Abstract

The invention discloses a Management Information Base (MIB) data uploading method and a Gigabit Passive Optical Network (GPON). The MIB data uploading method includes: S1 based on varieties of preset uploading attributes, attributes of all attributes in an Optical Network Unit (ONU) or an MIB of an Optical Network Termination (ONT) according with the varieties of the preset uploading attributes are marked as effective attributes; S2 the effective data lengths of the effective attributes are marked sequentially one by one; S3 the effective attributes are read sequentially from the MIB one by one, the effective attributes having the same effective data lengths are packaged to be one OMCI message on the basis of the effective data lengths marked in the effective attributes, and the OMCI message is transmitted to one Optical Line Terminal (OLT). According to the MIB data uploading method, uploading of unnecessary attributes is reduced by marking the effective uploading attributes, a part of system resources is saved, information configuration accuracy is improved, and accordingly the uploading efficiency is improved.

Description

Technical field [0001] The invention relates to a MIB (Management Information Base equipment management information base) data upload method and a GPON network (Gigabit-Capable Passive Optical Network), in particular to an ONT (Optical Network Terminal optical network) in a GPON network. A method for uploading MIB data between a network terminal) or an ONU (Optical Network Unit) and an OLT (Optical Line Terminal) and a GPON network using the MIB data uploading method. Background technique [0002] The rapid growth of Internet users and the popularization of broadband network applications are driving the development of network infrastructure. The total bandwidth of the network is increasing at a rate of doubling every six months. New network applications and network technologies such as VoIP (Voice over Internet Protocol network for voice transmission), IPTV (Internet TV), and online games are also constantly improving the network Bandwidth presents new challenges. In the long r...
