Detailed Description
The following further description of the present invention, in order to facilitate understanding of those skilled in the art, is provided in conjunction with the accompanying drawings and is not intended to limit the scope of the present invention. In the present application, the embodiments and various aspects of the embodiments may be combined with each other without conflict.
Referring to fig. 1A, the present invention provides a CTP generation method for an intermediate connection termination point, as shown in fig. 1, the method includes:
step 100, acquiring a CTP format and acquiring a CTP model according to the CTP format;
referring to fig. 1B, in step 100, said obtaining the CTP format and obtaining the CTP model according to the CTP format includes:
step 110, importing the CTP format provided by the user.
In the embodiment of the present invention, a CTP format is predefined in the CTP generating device, where the CTP format may be one of a virtual network connection diagram or a configuration file, and a CTP resource to be configured by a user may be described by the CTP format, and the user provides corresponding information according to the defined CTP format, for example, provides a corresponding virtual network connection diagram or a configuration file.
The CTP format provided by the user carries the CTP and CTP information desired by the user, and the CTP and CTP information desired by the user can be automatically generated according to the parameters planned by the user by importing the CTP format provided by the user. In the CTP format, one or more attributes of a network element to which a CTP belongs, a single plate, PTP, CTP number, type, connection state, direction, mapping manner, state, service rate, whether CPTP is present, and the like may be defined.
Step 120, judging whether the CTP format provided by the user is available;
step 140, when the CTP format provided by the user is available, decomposing the obtained CTP format into minimum attribute units;
in this embodiment of the present invention, the minimum attribute unit includes one or more of network elements to which a CTP belongs, a single plate, PTP, CTP number, type, connection state, direction, mapping manner, state, service rate, and whether the attribute is an attribute of CPTP.
And 150, generating a CTP model according to the minimum attribute unit obtained by decomposition.
Wherein step 150 comprises:
step 151, determining the association relationship between the network element, the single board, the PTP and the minimum attribute unit. The network element, the single board and the PTP are used as father nodes for modeling again, and the CTP is used as a child node to be associated with each network element, the single board and the PTP.
And 152, constructing an integral and hierarchical CTP model and an object data structure according to the determined association relation.
Preferably, the CTP model is defined as a tree structure, and the characteristics of clear hierarchical relationship, clear parent-child relationship and clear hierarchy relationship from top to bottom in the tree structure can help to improve the efficiency of the subsequent algorithm. The EMS of the network management system can be used as a father node of a first layer, the EMS of the network management system is used as a father node of a network element, the network element is a father node of a single board, and the single board is a father node of a PTP. A child node may inherit the CTP attribute from a parent node such that some or all of the CTP attribute is shared between the child node and the parent node.
Step 160, detecting whether CTP attribute information in the CTP model is complete; and when the CTP attribute information in the CTP model is incomplete, completing the CTP attribute information supplement according to a preset supplement rule.
In step 100, after step 120, the step 100 further includes:
and step 130, when the CTP format provided by the user is unavailable, generating a CTP model according to a preset default generation rule.
If the CTP format provided by the user is not available, a CTP model may be generated according to the rules generated by the CTP default. For example, in the default generation mode, the default CTP number, name, direction, type, wavelength, and traffic rate are respectively customized for the OCH, OAC, and OTU services. The CTP configuration mode most used by the user (generated according to the OTN end-to-end simplest service model) can be set, and OCH, OAC and OTU port rates are created by default, wherein 2 CTP resources, namely opscp and OCHCTP, are created in the OCH layer shortage. OTU layer shortage creates 3 CTP resources, which are opscp, OCHCTP and odutp, respectively. The OAC hierarchal province creates 1 CTP resource, which is oactp. And provides the interface for the user to operate the port layer rate, and can add, delete and change CTP resource information.
In addition, in addition to the CTP configuration mode most frequently used by the user, a CTP model can be generated according to other more complex business models as required, and the default CTP generation rule is modified.
For example, the CTP generating device may store a plurality of default CTP models, and may also store a plurality of CTP rules for user selection.
In this example, when it is determined that the CTP format provided by the user is not available, the CTP model is generated according to a predetermined default generation rule. Further, the CTP model may be generated directly according to a default generation rule according to a user selection.
In another example of the present invention, said obtaining the CTP format and the CTP model according to the CTP format in step 100 comprises:
and receiving a generation rule selected by a user or a default CTP model selected by the user, and generating a corresponding CTP model.
Step 200, packaging the CTP model into a recognizable command of the network management equipment, and sending the recognizable command of the network management equipment to the network management equipment, wherein the recognizable command of the network management equipment is used for providing the CTP model for the network management equipment so as to generate the CTP according to the CTP model.
Currently, the U3 network management device uses an ASN1 interface, and the command recognizable by the network management device can be encapsulated into an atomic command, so as to be sent to the network management device through the ASN1 interface.
When the CTP generating device sends the recognizable command of the network management equipment to the network management equipment, the CTPs can be encapsulated into an atomic command one by one and sent to the network management equipment, and multiple CTPs can also be sent to the network management equipment as an atomic command list.
