The embodiment of the invention provides a kind of version of Operation and Maintenance Unit of network element to switch way and a kind of Operation and Maintenance Unit monitoring module, and concrete technical scheme is as follows:
The embodiment of the invention realizes that by the method that increases an indirect layer version of OMU switches.As at OMU monitoring module of OMU deploy.This module comprises: monitoring unit is used for revising the startup catalogue of the OMU Software of OMU configuration file; Start unit, be used for reading the OMU configuration file OMU Software the startup directory information and start OMU Software according to described startup directory information.This module be used to realize to OMU Software startup, reset and monitor, so this module can not upgraded with the upgrading of OMU Software.This OMU monitoring module can be used as service registry and advances operating system, start with os starting, and OMU Software can be started by the OMU monitoring module.Described OMU Software starts flow process as shown in Figure 1, comprising:
Step 101, os starting service, the OMU monitoring module starts;
Step 102, OMU monitoring module obtain the directory information of operation version in the configuration file;
The OMU Software of step 103, startup operation version.
It is that example is set forth concrete technical scheme that present embodiment has two service areas with OMU, and then the catalogue at the related software place of OMU can be planned to three parts: public directory is used to deposit switching monitoring unit software, edition configuration file, other public directory etc.; Main with service area (operation the release directory), be used to deposit the program file, data file, patch file of the required loading of operation version etc.; Standby service area (standby the release directory) is used to deposit program file, data file, patch file of the required loading of standby version etc.Wherein moving the release directory is relative with standby the release directory, and the catalogue at the current OMU Software place of moving is operation the release directory, and corresponding catalogue is standby the release directory.The OMU Software run duration, can not make amendment to the software in standby the release directory, file and data, after OMU Software is upgraded to redaction like this, state before the software of early version and data keep switching, in case when needing rollback, can return to the state before early version switches fully, not influence the business function of network element.
As shown in Figure 2, OMU version switching flow specifically comprises:
Step 201, user send the switching version command;
Step 202, operation version OMU Software check whether standby version is complete, and in this way, then execution in step 203, and step 202 is an optional step;
Step 203, operation version OMU Software send the switching version command to the OMU monitoring module;
Step 204, OMU monitoring module are revised as current standby version place catalogue with the startup catalogue of the OMU Software in the configuration file;
Step 205, OMU monitoring module order OMU Software withdraw from process;
Step 206, according to order end process, stop the OMU Software of current operation version;
The OMU Software that step 207, OMU monitoring module read in the amended configuration file starts directory information;
Step 208, restart OMU Software, revise because the OMU Software in the configuration file starts catalogue, the OMU Software that reruns is the OMU Software in former standby the release directory, has therefore realized the version switching.
The method that the embodiment of the invention also provides a kind of veneer to load.
For veneer, can not establish the service area, also can be provided with more than one service area, being provided with two service areas with veneer in the present embodiment is that example is set forth.For example, veneer is provided with two FLASH flash memory service areas, also can adopt other storage medium.Described FLASH space can be divided into two parts: the master promptly moves version space with the service area, and standby service area is standby version space.Operation version space and standby version space also are comparatively speaking, can deposit files such as program file, data file, patch file in each version space.
Veneer can adopt no disc system startup method commonly used in the present embodiment, for example, adopts BOOTP (Bootstrap Protocol, boot protocol) channeling conduct to start.Board Power up or reset after, boot can be broadcasted the BOOTP request message to OMU, OMU gives veneer loopback BOOTP response message.When veneer loads version file such as required program and data from OMU or the flash memory of self, the related versions file is carried out consistency relatively according to the check information of load application version file.Described check information can be carried by the BOOTP response message that OMU issues veneer.
Described check information generates by following method: add a file header to All Files, file content is attached to the file header back, file content draws a check value according to checking algorithm, fills out in file header.Whether the check value by comparison document is consistent judges whether the related versions file is the version file of required loading.For example, with CRC (Cyclic Redundancy Check, cyclic redundancy check (CRC)) algorithm comes the calculation check value, network element is when making version and making patch, go out the CRC check value of BIN file and patch file according to the CRC algorithm computation, and add the file header that carries described CRC check value for described file.The data of network element can be managed concentratedly by OMU, as OMU data file of data generation with veneer, veneer can obtain its required configuration data from OMU, be operation version file and the standby version file of preserving veneer among the OMU, veneer can learn that the file preserved among self FLASH and OMU go up corresponding file and whether be consistent and then can obtain its required file from OMU by the CRC check value of comparison document.
Come concrete implementation procedure is described below in conjunction with accompanying drawing, as shown in Figure 3, the flow process that veneer loads specifically comprises:

Step 303, OMU obtain the single board information in the described request message after receiving this BOOTP request message.According to the relevant configuration information that described single board information is inquired about this veneer, obtain the IP address of veneer, the CRC check information in the file header of the main files such as program file, data file and patch with, standby service area that read the described veneer preserved among the OMU.
Step 304, OMU insert described CRC check information and veneer IP address in the BOOTP response message, this BOOTP response message of broadcasting loopback.The request of BOOTP agreement and response format are as shown in Figure 4, described CRC check information and veneer IP address can be inserted in the field of BOOTP response message, for example, can insert the particular vendor information field of this message, promptly utilize described particular vendor information field to carry the check information of version files such as the program of the required loading of veneer, data, patch.
After step 305, veneer are received response message, read the above-mentioned CRC check information of wherein carrying, load required file according to described CRC check information.For example, can be preferential according to the primary area, maximum match principle mates: promptly pay the utmost attention to the primary area and load from FLASH, to reduce from time that OMU loads and to write the FLASH time, so that veneer can start as early as possible; Lack loading as far as possible,, reduce influence, prolong the useful life of FLASH simultaneously other task to write FLASH less as far as possible from OMU.Specific implementation can comprise one of following mode:
(1) if has at least the test value of the operation version file of the described veneer of preserving among the CRC check value of described load document of a service area and the OMU to be consistent in two FLASH service areas of veneer, the FLASH service area load application version file that is consistent from described and OMU of veneer then, and this service area is set to the main service area of using; Perhaps,
(2) if two service areas of veneer all have the test value of the operation version file of the described veneer of preserving among the CRC check value of part load document and the OMU to be consistent, then from two service areas of veneer, select one to use the service area as the veneer master, the consistent file of preserving with described OMU from the FLASH master of this selected veneer with loading the service area, inconsistent file loads from OMU, so that the file amount minimum that loads from OMU; Perhaps,
(3) if the CRC check value of all load document of two FLASH service areas of described veneer all with OMU in the test value of operation version file of the described veneer preserved inconsistent, the test value of then checking the standby version file of the described veneer of preserving among CRC check value that whether described load document is arranged in two service areas of described veneer and the OMU is consistent, if having then selecting this FLASH service area is the standby service area of veneer, from OMU, load required version file; Perhaps,
(4) select a service area to use the service area arbitrarily, from OMU, load required version file as the main of veneer.
Step 306, operation monoboard programme.
Step 307, veneer are in the mode of background task, and the operation version file that will load from OMU writes the veneer master and uses service area FLASH, make the main consistent with what preserve among service area file and the OMU of veneer.This step is an optional step.
Step 308, veneer load the standby version file of required veneer in the mode of background task from OMU, write the standby service area FLASH of veneer, make preserve among standby service area file and the OMU of veneer consistent.This step is an optional step.
The method that the embodiment of the invention also provides a kind of network element version to switch.In the described network element of the embodiment of the invention, OMU and veneer are all supported many versions, present embodiment all is provided with two service areas with OMU and veneer and supports that two versions are that example illustrates concrete technical scheme, when this moment, version switched, veneer does not need from OMU load software and data, thereby guarantees to realize that version switches fast.
The network element version handoff procedure specifically comprises:
(1) user sends OMU version switching command;
(2) OMU carries out the version switching, and the concrete grammar of switching is identical with the method that OMU version described in the embodiment of front switches, and no longer repeats herein;
(3) after the switching of OMU version is finished, send reset command to veneer;
(4) board resetting, boot can be to OMU broadcast request message, OMU gives veneer back response message, thereafter the loading procedure of veneer is identical with the process that veneer described in the embodiment of front loads, no longer repeat herein, then veneer has loaded and the corresponding version file of the current operation version of OMU, thereby the version of having realized veneer switches.
In sum, the network element version switching method that the embodiment of the invention provides switches OMU and veneer by substep, carries out the OMU version earlier and switches, if the OMU handoff failure, then veneer is not affected, and continues normally to provide the net element business function; Behind the OMU handover success, part veneer handoff failure then can carry out Operation and Maintenance to veneer by OMU, gets rid of single board default, makes veneer continue operation.Thereby the network element version switching method that the embodiment of the invention provides effectively controls handoff procedure, and risk of handover is little, and is simple and reliable fast.The method that the OMU version of the network element that the embodiment of the invention provides switches has realized quick, simple and reliable switching version by an OMU monitoring module is set in OMU, providing of net element business is not provided yet.The OMU monitoring module that the embodiment of the invention provides realized to OMU Software startup, reset and monitor.The veneer loading method that the embodiment of the invention provides adds the file header that includes check information in version file, even make under the situation of multi-work space, also can load and move correct version file during single board starting; Simultaneously, veneer has improved the starting efficiency of network element preferentially from self load document; Behind the single board starting, the mode that starts with the backstage writes the corresponding work district of veneer from the OMU load document and with described file, reduces the influence that single board service is handled, and has guaranteed that simultaneously the version of veneer and OMU are consistent.
Obviously, those skilled in the art can carry out various changes and distortion to the present invention and not break away from the spirit and scope of the present invention.Like this, if these modifications of the present invention and distortion belong within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and is out of shape interior.
