In the field of operator network communication, there are two main ways for configuration and control of network devices: and integrating a commercial manual operation and maintenance mode and an SDN controller mode.
The manual operation and maintenance mode of the integrator generally uses a CLI command to directly interact with the equipment to complete operations such as equipment opening, backbone relay opening, service opening, equipment upgrading and maintenance and the like. This approach is greatly affected by space and time, while being limited by the skill level and efficiency of the network engineer. Once the response to a major failure is not rapid enough, an unpredictable loss of customer service may result.
Regarding the manner of an SDN (Software Defined Network) controller, the SDN controller has a globally controllable control plane and an efficient forwarding plane, and a controller user can make a decision based on Network information of the whole Network, and adjust and optimize according to real-time changes of Network traffic. The adjustment and optimization comprise the steps of issuing maintenance change to equipment, opening services and the like.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings.
In one embodiment, the present invention provides an atomic capability storage and rendering method for vendor YANG files, the overall flowchart of the method is shown in fig. 1, and the method comprises:
after a vendor YANG file is acquired, judging the YANG file, if the YANG file is not an updated YANG file, performing tree-form transformation on the atomic capability corresponding to the YANG file, falling into an atomic capability storage table in a database, recording the version of the current atomic capability, performing template combination on the atomic capability, issuing configuration to router switch equipment by using a template, and persistently storing the issued configuration; and if the YANG file is an updated YANG file, searching a historical template formed by the atomic capability combination and forbidding, simultaneously recording the atomic capability of the previous version into a historical atomic capability storage table, performing tree-form transformation on the atomic capability corresponding to the new YANG file, finally recording the updated atomic capability into a new atomic capability storage table, and combining to form a template for subsequent configuration and issuing.
Specifically, the data nodes that exist are determined according to the vendor provided specification YANG file. Analyzing the vendor-supplied canonical YANG file, identifies the main four types of data nodes that need to be supported: the system comprises leaf nodes, leaf list nodes, container nodes and list nodes, wherein the four data nodes are in a nested relation. The data structure needs to include information such as node data type, node description information, node enumeration value, value range, default value and the like. In addition, there are interdependencies between data nodes, such as list node mandatory items and list node unique values, and special processing is required for such nodes, which will be explained in the subsequent steps.
According to the determined four types of data nodes, determining the hierarchical relationship and the tree structure among the nodes, wherein the container nodes and the list nodes can be used as parent nodes, the leaf nodes and the leaf list nodes can be used as child nodes, and the relationship among the data nodes conforms to the tree structure, so that the data nodes are stored in a relational database in a tree structure mode. When the list nodes appear as nodes, if the list contains N elements, the N elements are all used as child nodes of the current list nodes.
After the four types of data nodes are determined, a database storage structure conforming to a tree structure is designed. First, a type field is needed to identify a node type, and container, leaf, list and leaf list nodes are designed to represent a container node, a leaf node, a list node and a leaf list node respectively. The parent field is used for storing the parent-child relationship among the nodes, for a plurality of YANG files provided by a manufacturer, each YANG file corresponds to one atomic capability, a uniform root node root bit is set for all the atomic capabilities, and when the root bits are inquired, the full amount of atomic capability information can be obtained. And setting a child _ exit field matched with a parent field for identifying whether a child node exists in the current node, wherein for the nodes of leaf and leaf list types, parent must exist and child must not exist.
All the other database fields are auxiliary fields, and the name of the node is identified by the name of the field; for a leaf node, the default value of the node needs to be saved, and the default value of the current node is recorded by using a default field.
Analyzing swagger files provided by manufacturers, analyzing whether the atomic capacity is newly increased, if the YANG files are not newly increased versions, performing tree-forming transformation on the nodes in the swagger files by using a tree-forming transformation algorithm, and storing the atomic capacity in a warehouse. If the YANG file is a new version, a template using the atomic capability needs to be searched, the template is forbidden, the old atomic capability falls into a historical library, and the new atomic capability is recorded in the current library.
For the YANG file provided by the manufacturer, the relationship between the nodes is not a tree structure in a strict sense, because the nodes of the list and the leaf list types exist, the stored atomic capability and the template formed by combining the atomic capability need to be subjected to treelization transformation, and the positions of the child nodes of the list and the leaf list are identified through the index, so that the instantiation object of the list to which the child nodes belong under the list can be effectively distinguished. As shown in FIG. 2, the left side is a general tree structure, where root is the root node, aaa and acl are the child nodes of root, id and seq are the child nodes of aaa, rule is the child node of acl, and the relationship between nodes is clear. The right structure is a modified tree structure, it can be known from the figure that aaa is a list type node, although the sub-nodes of aaa are id and seq, there are combinations of multiple sets of id and seq, and different sets need to be distinguished by index.
Nodes in atomic capability can be combined as a minimum unit to form a template. One atomic capability acl is as follows:
the following nodes of the atomic capability are selected to be combined to form a template:
it can be seen that the atomic capability acl has a plurality of child nodes, but when acl is combined with other atomic capabilities, only the nodes required by the target template can be selected, and the whole acl atomic capability does not need to be combined. Note that the fetched node must be a leaf node or leaf list node and must contain all of the parent nodes of the leaf nodes.
In order to enable the template composed of atomic capability to support different values according to different scenes and avoid repeated creation of the template by a user, a calculated _ rule field is added in the template composed of atomic capability and a variable name is recorded. When the template is used in different service scenes, the meaning represented by the variable changes, and the variable in the template is assigned and issued to the equipment when the template is analyzed.
When interacting with the equipment, a transaction mechanism is used, configuration contents are issued concurrently or sequentially, and after the transaction scheduling is completed, the configuration contents of the issued equipment are recorded in a transaction dimension for viewing a history record.
For atomic capabilities stored in a database, the atomic capability structure relationship cannot be intuitively exposed to the user. Therefore, a data structure with understandable front end is provided, and information such as node names, node types, node values and child nodes is returned in a json format.
