Detailed Description
Before describing the embodiments of the present application, the terms referred to in the present application will be described and explained below.
A network configuration protocol (NETCONF) in the present application is a network management protocol based on extensible markup language (XML), and a network management device (for example, a device running a client) may configure and manage a network device (for example, a server device) using NETCONF. The network management device may implement management and configuration of the network device through a Remote Procedure Call (RPC) message defined by NETCONF. The RPC message includes a request message and a response message, e.g., the network management device encapsulates the RPC request content in a < RPC > message and sends it to the network device. The network device receives the RPC request message and executes an operation according to the RPC request. The network device may encapsulate the result of the execution operation in a < rpc-reply > element and respond with a response message to the network management device.
The presentation layer state transition protocol (REST configuration) in the present application is a representation state transition (REST) protocol, which is a network management protocol based on hypertext transfer protocol (HTTP) and can access data in the YANG model. RESTCONF is a simplified version NETCONF realizing RESTful style, and data defined by a YANG model can be edited and inquired through PUT/POST/DELETE/GET of HTTP.
YANG in the present application is a data modeling language For modeling configuration data, status data, remote procedure calls and network management protocol notifications, and the detailed description about YANG can be according to the related sections of Request For Comments (RFC) 6020 and RFC 7950. The YANG model may describe the data in Extensible Markup Language (XML) format or JavaScript Object Notation (JSON) format.
The capability (capability) in this application is a function that can extend the basic function of NETCONF, and each capability is identified by using a Uniform Resource Identifier (URI). In the capability set composed of a plurality of capabilities, the operation content supported by the device can be added, and the operation range of the existing configuration object can be expanded. The management device may discover the capability sets supported by the network devices through interactions and may define new operations, parameters, and configuration objects for the capability sets.
For example, NETCONF supports definition of capabilities, NETCONF defines base1.0 and standard capability sets (capabilities), and a network device may also define its own capability set through NETCONF. For example, NETCONF management devices and managed network devices support base1.0 capabilities, and NETCONF provides a semantic specification for defining the capabilities syntax, which allows network management devices to interact with network devices and define new capabilities.
Generally, after the network management device and the network device establish a secure link-oriented session (session), the network management device may send an RPC request to the network device, and the network device receives the RPC request and executes an operation in the RPC. In the process, regardless of whether the network device can execute the operation, the network device can only execute the operation according to the operation instruction information issued by the network management device, and if the network management device wants the network device to execute the operation after determining that the specific condition information is met, the operation needs to be executed by means of manual means. Therefore, the current implementation scheme is not flexible enough, and needs to determine whether the conditions are met through manual operation, which results in low efficiency of managing the network devices.
The method defines new capability on the network equipment, the network equipment can judge the condition information through the capability, and the network equipment executes the operation in the operation indication information associated with the condition information when the condition information is met or returns the unsatisfied information when the condition information is not met. The method improves the efficiency of managing the network equipment and realizes network management more intelligently. The method, the network equipment and the system are based on the same inventive concept. The principles of the method, network device and system for solving the problems are similar, and therefore, embodiments of the network device, method and system can be mutually referred to, and the same or similar parts are not described again.
One possible application scenario and network device of the present application is described below with reference to fig. 1. The application scenario includes a network management device and a network device, specifically, such as the management device 101, the network device 102, and the network device 103. The management device 101 interacts information with the network device 102 and the network device 103 through NETCONF or RESTCONF, respectively. The Management device 101 may have a function of Network Management, that is, may operate an Enterprise Management System (EMS) or a Network Management System (NMS). The network manager may be deployed on a Virtual Machine (VM) or Linux in the form of software. The management device may also be a device running client software, such as a mobile phone, a Personal Computer (PC), a notebook computer, an ultra mobile PC, a personal digital assistant, or a removable wearable device. Network device 102 and 103 may be a router, switch, firewall, enterprise server, operator server, or service provider server.
The management device 101 may send a request message to the network device 102 or the network device 103, where the request message is used to implement a request for creating, deleting, modifying, or querying data of the network device. After receiving the request message, the network device 102 or the network device 103 processes the request message to create, delete, modify, or query data of the network device. After the request message is processed, the network device sends a response message to the management device to report the processing result of the request message.
Referring to fig. 2 in conjunction with the application scenario shown in fig. 1, a method for managing network devices is provided, where the method includes:
s201, the network equipment receives the first message and obtains operation instruction information and condition information from the first message.
The first message may be a NETCONF message or a RESTCONF message. The first message includes operation instruction information and condition information associated with the operation instruction information, where the condition information is used by the network device to determine whether data or resources on the network device satisfy the condition information, the operation instruction information is used to instruct the network device to execute the content of the operation instruction information, and the condition information and the operation instruction information have an association relationship, for example, whether the operation instruction information is executed by the network device or not needs to be determined according to the condition information by the network device. The network equipment obtains the first message and analyzes the first message to obtain condition information and operation indication information.
In one example, the network device may define a corresponding data model according to the condition information, and the data model may include a list (list) of condition information, and the definition of the YANG model may enable the network device to identify and process the condition information from the first packet. For example, the network device may define a YANG model according to the condition information, where the YANG model includes condition information, such as list of if-match, and the condition information includes node parameters and attribute parameters, as follows:
if the condition information includes a condition information set, i.e., includes a plurality of condition information, the YANG model may further include other condition information than the above condition information, as follows:
as shown above, two or more leaves (leaf) may be defined for the if-match list and the then list in the YANG model, for example, the leaves may be defined as two condition parameters, i.e., a node (node) and an attribute (attribute), and corresponding values, and other condition parameters and corresponding values may also be defined as needed.
Moreover, other types of operation instruction information can be defined through the YANG model according to requirements, and the get-config is defined as follows:
copy-config is defined as follows:
in one example, the condition information in the first message includes a condition parameter and a value of the condition parameter. The condition parameter includes a node parameter and a value or an attribute parameter corresponding to the condition parameter and a value corresponding to the attribute parameter. The network device 102 in fig. 1 is taken as an example for illustration. In the application scenario shown in fig. 1, the condition information (if-match) and the operation indication information (edge-config) obtained by the network device 102 include two condition parameters that are two leaves (leaf), a first leaf is a condition parameter and a value of a node value (node value), and a second leaf is a condition parameter and a value of an attribute value (attribute value).
In one example, before the network device receives the first message, the network device obtains capability information, where the capability information is used to indicate that the network device has a capability of determining whether the network device satisfies the condition information.
For example, the network device is exemplified as the network device 102 in fig. 1. In the application scenario shown in fig. 1, the network device 102 defines a new capability set for indicating that the network device 102 has the capability of determining whether it satisfies the condition information.
S202, the network equipment judges whether the data or the resources meet the condition information.
In one example, the network device determines whether the data or resource of the network device satisfies the condition information according to the condition information obtained from the first packet. Or the network equipment acquires the condition information which is the same as the condition information in the first message and judges according to the acquired same condition information and the data of the network equipment.
In an example, before the network device executes the operation instruction information of the first packet, the network device first determines whether the condition information in the first packet is satisfied, so that the network executes the operation instruction information according to the condition information, and the efficiency of managing the network device is improved.
An example of a first packet including a node value is shown as follows:
in connection with the above example, xpath in getnodalue (xpath) is used to describe the path for which an instance node is to be obtained, and the xpath function represents a query on the device for the value of the node, and getnodalue (/ debug: debug/debug: cpu-info/debug: system-cpu-use) as shown above is used to obtain the value of the system-cpu-use node. For example, the condition-node getnode value (/ debug: cpu-info/debug: system-cpu-use < 80% > </condition > is used to indicate that the value of the system-cpu-use node is less than 80%, that is, the data or resource of the network device satisfies the condition information, otherwise, the condition information is not satisfied.
An example of a first packet including attribute values is shown below:
in connection with the above example, xpath in getnodedattribute (xpath, attribute) is used to describe the path of the instance node to be obtained, attribute describes the attribute of the xpath node, and the xpath function represents the value of querying the device for the node matching attribute, such as getnodalue (/ debug: debug/debug: cpu-info/debug: system-cpu-use, default), which represents the value used to obtain the attribute of system-cpu-use node default. For example, the < condition-node > getnododeattribute (/ debug: cpu-info/debug: system-cpu-use, default)! And when the default attribute value of the system-cpu-use node is not equal to the false, the condition returns to true, that is, the data or the resource of the network device satisfies the condition information, otherwise, the condition information is not satisfied.
The < exit-config > operation in the above example is used to load all or part of the configuration data into the specified target configuration data set, and the < exit-config > operation supports multiple loading configuration modes, for example: local files, remote files, online editing; if not, these new configuration data are created. The < config > element may also be encapsulated as a set of hierarchical configuration data defined by the data model, e.g., < data >. These configuration numbers must be placed in a specified namespace to enable the device to detect the data model that defines the configuration data that must comply with the constraints of the data model that are defined based on the capability set.
In an example, the operation indication information may also be other operation indication information such as < get-config > or < copy-config >, which replaces the < exit-config >, and this application is not illustrated.
In one example, a module is added to the netconf library of the network device to store a condition function corresponding to the condition information, such as a! Any one or combination of b, a, b, a < b, a > b, a like b, or, and, wherein'! If the front and back values are not equal, then returning true, and equal to returning false; "like" indicates that the character string which can match b in a returns true, and the character string which can not match b returns false; the general language has libraries which can be directly used, can synchronize the condition functions in the python libraries and supports extensibility.
The network device may obtain the node parameter and the attribute parameter from the first packet. And the network equipment judges whether the network equipment meets the condition information according to the node parameters and the attribute parameters and the condition function of the netconf library of the network equipment.
S203, based on the network device determining that the condition information is not satisfied, the network device generates a response message.
And if the network equipment determines that the condition information is not satisfied, the network equipment generates a response message aiming at the first message. The response message includes the unsatisfied information of the network device.
In one example, the unsatisfied condition information included in the response message may include one or more of an error identification (error-tag), an error type (error-type), an error rank (error-preference), error information (error-info), and an error Description (Description). For example, the response message includes an error identification (error-tag), an error type (error-type), and error information (error-info).
For example, the response packet may carry the unsatisfied information. As shown below, is one example of the possibilities for unsatisfied information and associated description;
error-tag:condition-denied
error-type:protocol,application
error-severity:error
error-info:name of the bad condition
Description:implement the requested protocol operation or data model is denied because condition failed.
the method includes that a character string for identifying an error condition is contained in < error-tag >, and a new description of the error condition of < error-tag > is added, for example, condition-distorted is used for indicating that the error condition is rejection condition information, and it can be understood that the error condition is that data or resources of the network device do not meet the condition information.
< error-info > contains the specific error type of the protocol or data model, and the present application adds a new description of the content of the < error-info > error, e.g., the name of the bad condition information.
< Description > is used to describe error specification, for example, the implementation of the requested protocol operation or data model is used to indicate that the requested protocol operation is executed or the data model is rejected because the condition information fails.
The network device may select one or more of the above unsatisfied messages to add to the response message as needed.
In one example, when the network device determines that the condition information (if-match) is supported according to the capability, the network device reads the condition parameter in the condition information (if-match), and determines whether the obtained result of the function condition defined in the netconf library is true or false. If the network equipment does not meet the condition information, the network equipment does not process the content in the operation indication information and returns a response message, wherein the response message comprises unsatisfied information that the network equipment does not meet the condition information. Here, the condition information may include a plurality of condition parameters, for example, a union including < condition-node > </condition-node > and < condition-attribute > </condition-attribute >, and when both are satisfied, the condition is satisfied, and when one of the two is not satisfied, the condition is not satisfied.
S204, based on the network equipment determining that the network equipment meets the condition information, the network equipment executes the operation instruction information.
In one example, if the network device determines that the network device satisfies the condition information through the judgment, the network device executes the operation instruction information.
In one example, when the network device determines that the capability information (if-match) is supported according to the capability information, the network device reads a condition parameter in the condition information, and determines whether a result of the condition is true or false according to a function defined in the netconf library. If true, the network device continues to process the content of the operation indication information.
Fig. 3 is a schematic flow chart of a method for managing network devices according to the present application. The network device in fig. 3 may be network device 102 or 103 in the scenario shown in fig. 1. The method comprises the following steps:
s301, the network device obtains the ability of supporting judgment of the condition information.
For example, in the application scenario shown in fig. 1, the network device 102 defines a new capability information for describing the capability of the network device 102 to determine whether its data or resource satisfies the condition information (e.g., if-match). For example, the capability information may be defined as follows: < capability > http:// XXX/netconf/capability/condition > wherein "XXX" needs to be determined according to a defined vendor or standard organization.
S302, the network device defines a data model supporting the condition information.
In the scenario shown in fig. 1, the network device 102 defines a data model, such as a YANG model, that supports determining conditional information. For the definition, reference may be made to the relevant description in step 201 in fig. 2.
S303, the management device sends a request message carrying the condition information and the operation instruction information to the network device.
The management device may carry condition information and operation indication information through an RPC request message, which may include a plurality of condition information and a plurality of operation indication information, for example, including condition information if-match (condition1) …. the (condition2) … is used to carry two pieces of condition information, it may be understood that when the network device satisfies the condition1, the network device may normally execute the operation indication information associated with the condition 1; when the network device satisfies condition2, the network device may normally execute the operation instruction information associated with condition2, and so on, as follows:
the above scheme may be used in the rpc request message of < exit-config >, and also in the rpc request message of < get-config > or < copy-config >.
S304, the network equipment receives the request message.
And the network equipment receives the PRC request message sent by the management equipment and acquires the condition information from the RPC request message. The network device first determines whether it supports the determination of the condition information. The network equipment determines that the network equipment has the capability of supporting the judgment condition information according to the capability information defined in the capability set.
S305, the network device determines whether its data or resource satisfies the condition information.
After the network equipment determines the capability of supporting judgment condition information, the network equipment reads condition parameters and condition parameter values in the condition information, judges whether the result of the condition is true or false according to a function defined in a lib library of the network equipment, if the result is true, the network equipment meets the condition information, and if the result is false, the network equipment does not meet the condition information.
S306, if the network equipment does not meet the condition information, the operation indication information is not executed or skipped, and the unsatisfied information is returned.
If the network device does not meet the condition, the network device does not execute the operation indication information in the PRC request message, or skips the operation indication information in the PRC request message, and returns a PRC response message carrying the unsatisfied information, as follows:
in one example, the condition information may include a plurality of branch condition information, such as if-match (condition1) …. then (condition 2). If the network device does not satisfy condition1, the operation indication information associated with condition1 is not executed or skipped, and unsatisfied information that does not satisfy condition1 is returned; if the network device does not satisfy conditions 1 and 2, the operation indication information associated with condition1 is not executed or skipped, and the operation indication information associated with condition2 is not executed or skipped, and a response message including non-satisfaction information that does not satisfy conditions 1 and 2 is returned.
And S307, if the network equipment meets the condition information, executing the operation instruction information.
In one example, the condition information may include a plurality of branch condition information (conditions), such as if-match (condition1) …. the (condition 2). If the network device satisfies condition1, performing an operation associated with condition 1; if the network device satisfies condition1 and condition2, the operation instruction information associated with condition1 and the operation instruction information associated with condition2 are executed, respectively. After the network device executes the corresponding operation instruction information, a PRC response may be returned, where the PRC response includes < ok >, and may also include identification information of the satisfied condition.
In one example, the network device may select one of steps 306 and 307 to perform, or perform steps 306 and 307.
Fig. 4 shows a schematic diagram of a possible structure of the network device involved in the above embodiments, and the network device 400 may have the functions of the network device in the embodiments shown in fig. 2 and fig. 3. Referring to fig. 4, the network device 400 includes: a receiving unit 401 and a processing unit 402. The network device 400 may have the corresponding functions of the network devices in the embodiments shown in fig. 2 and fig. 3, for example, the receiving unit 401 may execute the method corresponding to step 201 in fig. 2 and step 304 in fig. 3. The processing unit 402 can execute the method corresponding to steps 202-204 in FIG. 2 and the method corresponding to steps 305-307 in FIG. 3. The receiving unit 401 is configured to receive a first packet, where the first packet includes condition information and operation instruction information associated with the condition information. The processing unit 402 is configured to determine whether data of the network device satisfies the condition information according to the condition information, determine that the network device does not satisfy the condition information based on the network device, the network device does not execute or skip the operation instruction information, and generate a response packet for the first packet, where the response packet includes the network device unsatisfied information. Or the processing unit 402 determines that the network device satisfies the condition information based on the network device for executing the operation instruction information.
