Abstract
The invention discloses a method for the remote self recovery for maintenance and control of light communication equipment and a system thereof. The system comprises a net management system connected with a remote net element, wherein the remote net element particularly comprises a net element control plate, service single plates and a maintenance control unit; the remote net element also comprises a timing control unit; the net element control plate is used to receive maintenance control commands sent by the net management system, and retransmits the commands to other service single plates in the net element; the timing control unit is used to receive maintenance control commands sent by the net element control plate, and periodically retransmits the commands to the maintenance control unit; and, the maintenance control unit is used to process the maintenance control commands sent downward by the net management system. In the invention, the timing control unit is additionally arranged on the service plate, when the DCC byte of the service plate is obstructed due to the performing of the maintenance control and the remote recovery can not be preformed due to no net management, the service plate can automatically cancel the maintenance control, recover the communication function of the DCC byte and further recover the remote net management control.
Description
Technical field
The present invention relates to the optical communication technology field, relate in particular to a kind of at safeguarding control cause having no progeny in DCC (Data Communications Channel) communication link method and system of remotely automatic recovering in the optical communication equipment.
Background technology
In optical communication equipment, for orientation problem needs, provide some to safeguard control command usually, for example loopback setting, insertion alarm, insertion error code, shutoff laser etc.Because webmaster is to transmit by the DCC byte in the expense to the control command of long-range optical communication equipment, and the above-mentioned control command of safeguarding often may cause business board DCC byte obstructed, and the obstructed meeting of business board DCC byte causes webmaster to take off pipe, causing cancelling the order of safeguarding control can't issue, cancellation this moment safeguards that issuing of control command needs the DCC byte logical, and logical need the cancellation of DCC byte safeguards that control command issues, the two has been absorbed in a dead ring, thus cause professional and webmaster control all can't remote recovery.
Equipment for the processing mode of this problem is at present, minimizing may cause optical communication equipment to take off the maintenance control of pipe, for example insert alarm, insert error code, the operation that loopback is not supported port level is set, but obvious this way can't be avoided the problems referred to above fully, has also reduced the function of safeguarding control command simultaneously.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method and system of automatically recovering maintenance and control of optical communication apparatus remotely, this method can guarantee to safeguard that control command can both normal configuration, can remotely automatic recovering and safeguard that optical communication equipment that the control configuration causes takes off pipe.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of automatically recovering maintenance and control of optical communication apparatus remotely system, comprising: the network management system that is connected with remote network element, described remote network element specifically comprise network element control plate, service board, safeguard control unit, timing control unit;
The network element control plate is used to receive the control command of safeguarding that network management system sends over, and it is forwarded to other service board in the network element;
Timing control unit is used to receive the control command of safeguarding that the network element control plate sends over, and regularly is transmitted to and safeguards control unit;
Safeguard that control unit is used to handle the control command of safeguarding that network management system issues.
A kind of method of automatically recovering maintenance and control of optical communication apparatus remotely may further comprise the steps:
A: receive and regularly to safeguard control command, timing control unit is preserved configuration information, preserves T1 and cancellation T2 setup time setup time simultaneously;
B: timing control unit carries out automatic regular polling operation, with current time T and T1 and cancel setup time T2 and compare setup time, if satisfy T1＜=T＜T2, then carries out the processing of current configuration; If satisfy T1＜T2＜=T, then cancel the processing of current configuration.
Wherein, regularly safeguard that control command comprises described in the step a: alarm insertion, error code insertion, loopback setting or laser control.
The present invention has following beneficial effect:
The present invention is by increasing by a timing control unit at business board, when owing to safeguard that control causes that business board DCC byte is obstructed, webmaster takes off pipe and can't the situation of remote recovery under, business board can be safeguarded the cancellation of control automatically, recover DCC byte communication function, thereby recover remote network management control.
Description of drawings
Fig. 1 is a system construction drawing of the present invention;
Fig. 2 is the inventive method flow chart.
Embodiment
The present invention is by providing a kind of method and system of automatically recovering maintenance and control of optical communication apparatus remotely, owing to safeguard that control causes that business board DCC byte is obstructed, webmaster takes off pipe and can't the situation of remote recovery under, business board can be safeguarded the cancellation of control automatically, recover DCC byte communication function, thereby recover remote network management control.
Among the present invention for safeguarding control command interpolation time control, comprise one setup time T1 and cancellation T2 setup time (T1＜T2), the current time is T.
Timing system of business board inner setting, receive configuration order after,
If T＜T1＜T2, T1 safeguards the configuration of control in the setup time of appointment, cancels the configuration of safeguarding control at cancellation T2 setup time of appointment;
If T1＜=T＜=T2 then safeguards the control configuration immediately, cancel the configuration of safeguarding control at cancellation T2 setup time of appointment;
If T1＜T2＜=T thinks invalid control, carry out invalidation.
The present invention is described in further detail below in conjunction with drawings and the specific embodiments:
See also shown in Figure 1ly, comprising: specifically comprise network element control plate 102, service board 103, timing control unit 104, safeguard control unit 105 with network management system 101, the remote network element of remote network element wireless connections;
Network element control plate 102 is used to receive the control command of safeguarding that network management system 101 sends over, and it is forwarded to other service board 103 in the network element;
Timing control unit 104 is used to receive the control command of safeguarding that network element control plate 102 sends over, and regularly is transmitted to and safeguards control unit 105;
Safeguard that control unit 105 is used to handle the control command of safeguarding that network management system 101 issues.
See also shown in Figure 2ly, comprising:
Step 201: receive the timing controlled order and also preserve configuration information, preserve T1 and cancellation T2 setup time setup time simultaneously;
