It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the invention are capable of operation in sequences other than those illustrated or otherwise described herein, and that the "first" and "second" distinguishing between objects generally are not limited in number to the extent that the first object may, for example, be one or more.
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a flow chart of a method for upgrading ONUs in batches, which is provided by the invention, and the method can be applied to an OLT, as shown in fig. 1, and comprises the following steps:
step 100, based on upgrade configuration respectively associated with different ONU equipment types, negotiating wavelength channels with various different types of ONUs to be upgraded, and determining upgrade exclusive wavelength channels respectively corresponding to the various different types of ONUs to be upgraded; the upgrade configuration associated with any ONU equipment type comprises an upgrade file, a corresponding ONU version number after being upgraded by using the upgrade file, a used wavelength and an upgrade switch.
Step 101, based on the upgrade exclusive wavelength channels respectively corresponding to the various different types of ONUs to be upgraded, issuing upgrade files of the corresponding ONU equipment types to the various different types of ONUs to be upgraded.
Specifically, in order to realize batch upgrading of various different types of ONUs, the invention can pre-configure the association relation between upgrading configuration and ONU equipment types in the OLT equipment, each ONU equipment type is associated with corresponding upgrading configuration, when the ONU is upgraded, the OLT can carry out negotiation of wavelength channels with various different types of ONUs to be upgraded based on the upgrading configuration respectively associated with different ONU equipment types, so as to determine the upgrading exclusive wavelength channel of each ONU, and then issue upgrading files to each ONU through the upgrading exclusive wavelength channels, thereby realizing the function of simultaneously upgrading various types of ONUs in the negotiated different wavelength channels of the local side equipment OLT and the terminal equipment ONU.
For example, assuming that the ONU to be upgraded includes ONU1 of ONU device type 1, ONU2 of ONU device type 2, and ONU3 of ONU device type 3, the OLT may respectively negotiate wavelength channels with ONU1, ONU2, and ONU3, and the successfully negotiated wavelength channel is the upgrade dedicated wavelength channel of the 3 ONUs, and then the OLT may simultaneously issue upgrade files associated with respective device types to the 3 different types of ONUs through the successfully negotiated 3 wavelength channels, respectively.
In some embodiments, the OLT and the ONUs may negotiate the wavelength channel via an extended dynamic communication wavelength protocol (EDWP) based on Operation Administration and Maintenance (OAM) or an ONU Management Control Interface (OMCI).
In some embodiments, in an upgrade configuration associated with any ONU device type, the used wavelengths may be associated with ONU identities in order to more quickly determine the upgrade-specific wavelength channels to which the ONUs correspond.
In some embodiments, an upgrade configuration management function may be added in advance to the OLT, for managing upgrade configurations respectively associated with different ONU device types, where the design in the upgrade configuration management function is as shown in table 1 below.
Table 1 design example table in upgrading configuration management function
According to the method for upgrading the ONU in batches, the upgrading configuration associated with different ONU equipment types is configured in the OLT equipment, the OLT can negotiate the wavelength channels between the upgrading configuration and the ONU of different types to be upgraded based on the upgrading configuration, the upgrading exclusive wavelength channel of each ONU is determined, and then the upgrading file is issued to each ONU through the upgrading exclusive wavelength channel, so that the functions of the ONU of different types can be simultaneously upgraded in the negotiated different wavelength channels at the same time, and the batch upgrading efficiency of the ONU of different types is greatly improved.
In some embodiments, negotiating wavelength channels with a plurality of different types of ONUs to be upgraded based on upgrade configurations respectively associated with different ONU device types includes:
according to the upgrading switch and the ONU version number respectively associated with different ONU equipment types, determining a plurality of different types of ONUs to be upgraded;
and selecting idle wavelength and negotiating wavelength channels between various different types of ONUs to be upgraded according to the used wavelength associated with the ONU equipment type of the ONU to be upgraded.
Specifically, before upgrading, the OLT may determine which ONUs are upgraded according to the upgrade switch and the ONU version number in the upgrade configuration respectively associated with different ONU device types. For example, it may be determined which ONUs to upgrade based on Status, on_version, and onu_type fields in table 1.
In some embodiments, determining a plurality of different types of ONUs to be upgraded according to upgrade switches and ONU version numbers respectively associated with different ONU device types includes:
according to the upgrade switches respectively associated with different ONU equipment types, determining the ONU equipment type of which the upgrade switch is started;
traversing each ONU corresponding to the ONU equipment type started by the upgrade switch, and determining various different types of ONUs to be upgraded according to the ONUs of which the version numbers in each ONU are inconsistent with the ONU version numbers associated with the corresponding ONU equipment types.
For example, it may be determined which ONU device Type upgrade switches are on based on the Status field and the onu_type field in table 1. Assuming that the upgrade switches of the type 1, the type 2 and the type 3 are on, the ONU Version numbers of the ONUs of the type 1, the type 2 and the type 3 can be respectively matched with the ONU Version numbers in the Onu _version fields corresponding to the respective ONU device types, if the ONU Version numbers are consistent, the processing is not performed (i.e. no upgrade is required), and if the ONU Version numbers are inconsistent, the upgrade is required.
In some embodiments, selecting an idle wavelength to negotiate a wavelength channel with a plurality of different types of ONUs to be upgraded according to a used wavelength associated with an ONU device type of the ONU to be upgraded, including:
according to the used wavelength associated with the ONU equipment type of the ONU to be upgraded, determining idle wavelengths corresponding to the ONU equipment types of the ONU to be upgraded respectively;
and for any ONU equipment type, randomly selecting a wavelength from idle wavelengths corresponding to the ONU equipment type, carrying out negotiation of a wavelength channel between the selected wavelength and the corresponding ONU to be upgraded, and if the negotiation fails, re-selecting the wavelength to carry out negotiation until the negotiation is successful or all idle wavelengths corresponding to the ONU equipment type fail.
For example, assuming that the device types of the ONU to be upgraded include type 1, type 2 and type 3, which respectively correspond to a wavelength range, the OLT may determine, according to the wavelengths already Used in the used_wave array objects (for example, table 1) respectively corresponding to type 1, type 2 and type 3, idle wavelengths currently respectively corresponding to these 3 types, that is, other wavelengths than the Used wavelengths in the wavelength range corresponding to each type.
For any ONU equipment type, taking type 1 as an example, after determining the idle wavelength, the OLT can randomly select one wavelength from the current idle wavelength of type 1 and negotiate a wavelength channel between one ONU to be upgraded of type 1, after successful negotiation, the successfully negotiated wavelength channel can be used as the exclusive wavelength channel for upgrading of the ONU, and if the negotiation fails, the idle wavelength can be reselected for negotiation until the negotiation is successful. Of course, if all the idle wavelengths currently have failed negotiation, the ONU is temporarily not upgraded.
In some embodiments, after determining the upgrade specific wavelength channels respectively corresponding to the plurality of different types of ONUs to be upgraded, the method further includes:
and updating the used wavelength associated with the corresponding ONU equipment type according to the upgrade exclusive wavelength channels respectively corresponding to the plurality of different types of ONU to be upgraded.
Specifically, after the wavelength channel negotiation is successful, the OLT may issue an upgrade file by using the negotiated wavelength channel, and update the wavelength used in the upgrade configuration associated with the corresponding ONU device type in time, so as to avoid a problem in a subsequent upgrade stage. In some embodiments, the ONU identity may be updated into the upgrade configuration along with the used wavelength.
In some embodiments, after issuing the upgrade file of the corresponding ONU device type to the multiple different types of ONUs to be upgraded, the method further includes:
and if the upgrade confirmation information sent by any ONU is received, recovering the wavelength of the upgrade exclusive wavelength channel corresponding to the ONU, and removing the recovered wavelength from the used wavelength associated with the ONU equipment type of the ONU.
Specifically, after the upgrade file is transmitted, the ONU may send upgrade confirmation information to the OLT, and if the OLT receives the upgrade confirmation information, the OLT may recover the corresponding wavelength, and remove the corresponding wavelength and the associated ONU identifier (if the ONU identifier is associated with the corresponding wavelength and the ONU identifier) from the upgrade configuration, so as to timely release the wavelength resource. In some embodiments, the OLT may remove the associated wavelength based on the ONU identity.
The above method provided by the invention is illustrated by way of example of a specific application scenario.
The present example is based on a channel binding technology of a PON system supporting multi-wavelength transmission, and when a terminal device ONU is on-line, a local side device OLT and the ONU perform negotiation of a wavelength channel through an extended dynamic communication wavelength protocol EDWP based on OAM or OMCI. The association relation between upgrade configuration (including upgrade file, upgrade switch, etc.) and ONU equipment type is preconfigured in the OLT equipment. After the OLT starts the upgrading function, the OLT transmits a message of an upgrading file associated with the configured ONU equipment type to the ONU through the binding channel, so that the functions of the ONU of various types are upgraded simultaneously in different negotiated wavelength channels by the local side equipment OLT of the G/EPON system and the terminal equipment ONU. The main process of this example includes:
and S1, upgrading configuration management functions shown in table 1 are added in advance on the local side equipment OLT of the G/EPON system.
S2, after an upgrade switch of one or more ONUs is turned on the OLT, the OLT traverses the on-line ONU types and detects the ONU types on the subsequent on-line ONU types, if the ONU types are matched with the ONU Type in the upgrade configuration management function, whether the ONU Version number is consistent with the Onu _version of the upgrade configuration management is judged, if so, the ONU Version number is not processed, and if not, the ONU Version number is upgraded, and then the ONU is entered into S3.
S3, the OLT traverses Wave in the Used wavelength used_wave array object in the upgrade configuration management function, and randomly selects wavelength from idle wavelength as an upgrade exclusive wavelength channel of the ONU equipment. Negotiating wavelength channels through an extended dynamic communication wavelength protocol EDWP based on OAM or OMCI, starting upgrading after successful negotiation, and entering S4; and if the negotiation fails, reselecting the idle wavelength to carry out the negotiation until the negotiation is successful.
And S4, the OLT acquires an upgrade file from the upgrade configuration management function through the ONU equipment type, starts to transmit the upgrade file by using the wavelength channel negotiated in the S3, and records ONU information and the Used wavelength into a used_wave array.
And S5, after the transmission of the upgrade file is completed, the ONU transmits upgrade confirmation information to the OLT, the OLT recovers the wavelength, and the Used wavelength is removed from the used_wave array according to the ONU information.
And when the upgrade switch is closed, the ONU is not subjected to upgrade processing, and when the upgrade switch is opened, the S2 operation is repeated.
According to the method for upgrading the ONU in batches, provided by the invention, the type of the ONU to be upgraded is not single any more in the same time by utilizing the characteristics and advantages of multi-wavelength transmission, each ONU can independently share a wavelength channel to transmit an upgrade file for upgrading, the transmission speed of the upgrade file is high, and a plurality of versions of ONUs are upgraded at the same time without interference.
