In, the time interval resource block number choosing respective number inserts aend<1..n>_ timeslotnumlist or zend<1..n>_
In timeslotnumlist parameter；
Createandactivatesubnetworkconnection interface is called to create oduk circuit.
In technique scheme, in nms-ems management system, it is concrete that nms webmaster creates oduk circuit end to end
Comprise the following steps:
S101, each circuit disk is inquired about by getcontainedpotentialconnectionterminationpoints
The ctp information of lower the be possible to mapping path of physical port；
S102, basis type of service to be created determines the rank of odu, and chooses available from step s101 and map
Path suitable oduk ctp list；
S103, call getavailabletimeslotnum interface obtain oduk ctp available time slot Resource Block number row
Table；
S104, judge obtain available time slot Resource Block list whether meet requirement, if it is, going to step s105, no
Then, go to step s102；
S105, call createandactivatesubnetworkconnection interface create oduk circuit.
In technique scheme, the type of described " timeslotnumlist " is string, and form is x, x；y,y,y；
z,z,z；For representing the time interval resource block list that on oduk multiplexed path, odu at different levels take, at different levels between with "；" segmentation.
In technique scheme, described getavailabletimeslotnum interface be used for inquiring about physical port and
The available time interval resource block list of odu at different levels on oduk multiplexed path.
In technique scheme,
The type of described " aend<1..n>_ timeslotnumlist " is string, and form is x, x；y,y,y；z,z,z；
For represent a end points oduk at different levels take time interval resource block list, at different levels between with "；" segmentation；
The type of described " zend<1..n>_ timeslotnumlist " is string, and form is x, x；y,y,y；z,z,z；
For represent z end points odu at different levels take time interval resource block list, at different levels between with "；" segmentation.
In technique scheme, rank k according to odu at different levels on oduk multiplexed path chooses the time slot money of respective number
Source block number.
In technique scheme, when rank k=0 of odu, the time interval resource block count mesh of selection is 1；Work as k=1
When, the time interval resource block count mesh of selection is 2；As k=2, the time interval resource block count mesh of selection is 8；As k=3, choose
Time interval resource block count mesh be 32；As k=4, the time interval resource block count mesh of selection is 80.
The present invention supports any multiplexed path of oduk of ms-otn equipment and any service creation taking Resource Block, supports
The oduk of ms-otn equipment takies the inquiry of time interval resource block number, greatly reduces what the oduk Circuit Service of ms-otn equipment issued
Complexity.
