Embodiment
The main points of the embodiment of the invention are to adopt to restart type and to restart delay parameter restarts the ASON Control Node and effectively manages and control; Restart delay parameter and be used to restart preparation, help the consistency of the data of better maintaining Control Node own.
The embodiment of the invention adopts clearer and more definite parameter control method, may further comprise the steps:
When user's (or management plane) requires the ASON Control Node to restart, be with following parameter:
| Parameter | Explanation |
| The ASON node identification | The ASON node that sign need be restarted |
| Restart type (optional) | Control Node is restarted type.The major parameter implication is described as follows: Normal: restart the The whole control node; RSVP: restart RSVP; OSPF: restart ospf protocol; LMP: restart the LMP agreement; DDRP: restart the DDRP agreement; BGP: restart bgp protocol; MPLS: restart mpls protocol; LMGR: restart the tag control module; MS: restart the masterslave switchover module; DA: restart the discovery proxy module; TAP: restart the transmission proxy module; LRM: restart the Link Resource Manager module; CC: restart link control module; CallCC: restart the call controller module; Version expanded after other were treated; Default to Normal |
| Restart time delay (optional) | Restart Control Node again after waiting for certain hour (unit is second).If be 0s, expression is restarted immediately, defaults to 0s |
Control Node detects and need restart, and detects to restart parameter accordingly;
Restart type and restart delay parameter if restart not contain in the parameter, then the same with conventional method, restart the The whole control node immediately;
Restart type if restart to contain in the parameter, do not restart delay parameter, then according to restarting type and module dependence table is restarted corresponding module and upper layer module immediately but do not contain;
Restart type if restart not contain in the parameter, restart delay parameter, then start timer, and notify each module to restart preparation, then restart the The whole control node at timer time according to restarting delay parameter but contain;
Restart type and restart delay parameter if restart to comprise in the parameter, then start timer according to restarting delay parameter, and restart preparation according to restarting type and module dependence table notice corresponding module and upper layer module, then restart corresponding module and upper layer module at timer time.
The present invention is described in detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, the main flow process of the embodiment of the invention is described in detail as follows:
Step 1, Control Node receive the reset command line parameter legitimacy verification of going forward side by side;
Verification can avoid management plane (or user) to wait as long for immediately to management plane (or user) back-checking result (optional) after finishing.
This step is not the emphasis of the embodiment of the invention, and similar with conventional method, this place is no longer described in detail.
In the concrete application example of present embodiment, suppose to receive the reset command of management plane: ASON_RESET_NODE:3,11,60 (are the version of supporting to restart type and restart time delay.Wherein, the ASON node identification of the current ASON Control Node of parameter 3 expressions is 3; The TAP module is restarted in parameter 11 expressions; It is 60 seconds that time delay is restarted in parameter 60 expressions).Parameter verification success back returns success to management plane replys.
Whether step 2, Control Node are judged to have in the reset command and are restarted type parameter;
Restart type parameter if having, then judge whether to be Normal;
If be not Normal, then as shown in Figure 2, read module dependence table, search and the upper layer module of restarting the type parameter coupling, if find and the upper layer module of restarting the type parameter coupling, then write down this upper layer module data, this upper layer module also needs to restart synchronously.
If restart parameter is Normal, does not perhaps have in the reset command and restarts type parameter, then restarts for the The whole control node.
In the application example of present embodiment was described, restarting type was 11, and expression need be restarted the TAP module; Read module dependence table finds that DA module (parameter is 10) directly depends on TAP module (11), so the DA module is the upper strata Depending module of TAP module, also needs to restart.
Whether step 3, Control Node are judged to have in the reset command and are restarted delay parameter;
Restart delay parameter if having, then start timer, forward step 4 to and continue to carry out according to restarting delay parameter; Do not restart delay parameter if be not with, perhaps restarting delay parameter is 0, then jumps to step 5 and continues to carry out.
In the application example of present embodiment, restarting delay parameter is 60, and expression needs time-delay to restart in 60 seconds, and the time delay timer of restarting of startup is Timer (60).
Step 4 according to the result who obtains in the step 2, is restarted the preparation notification message to the module transmission that needs are restarted;
The module that need restart receive restart prepare notification message after, in time deposit the current information that does not deposit database as yet in database, and restart preparation (each module need finish the preparation of restarting be not quite similar).
In the application example of present embodiment, restart the preparation notice to DA and the transmission of TAP module.DA and TAP receive restart prepare notification message after, finish when pre-treatment and will not deposit database information in time depositing database in, finish restart preparation after, wait is restarted.
Step 5 is restarted corresponding module;
Timer time in step 3 is then restarted corresponding module; Perhaps do not restart back off timer, restart corresponding module immediately.
In the application example of present embodiment, when Timer (60) timer then, restart DA and TAP module.
Step 6 is restarted and is finished, and reports and restarts the result;
The module of restarting when needs is all restarted and is finished, and when perhaps failure occurring in the pilot process, the result is reported corresponding management plane (or user), and reboot process is finished.
In the application example of present embodiment, all restart successfully when TAP and DA module, report the TAP module to restart successfully to management plane.
