Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an embodiment of a method for processing a notification message by a northbound interface according to the present invention. In this embodiment, the northbound interface is pre-configured with a plurality of plugins and configuration information, and the configuration information records the corresponding relationship between each type of integrated network manager and the plugin to be loaded. The northbound interface can know which plug-ins should be loaded according to the corresponding relation and the comprehensive network management type of the communication link established with the northbound interface. The method for processing the notification message by the northbound interface comprises the following steps:
step S10, according to the received notification processing instruction, determining the comprehensive network management type of the communication link established with the northbound interface, and loading the corresponding plugin pre-configured in the northbound interface according to the comprehensive network management type and the configuration information.
In this embodiment, the configuration information records a name and a storage address of each plug-in set by the northbound interface, and the northbound interface can determine the name and the storage address of the plug-in to be loaded according to the configuration information after determining the type of the integrated network management for establishing the communication link with the northbound interface. Referring to fig. 2, fig. 2 is a detailed flowchart of step S10 in fig. 1. The step S10 is specifically performed as follows:
and step S11, determining the comprehensive network management type of the communication link established with the northbound interface according to the received notification processing instruction.
Step S12, scanning the configuration information, and determining the names and storage addresses of a plurality of plug-ins to be loaded according to the configuration information and the comprehensive network management type.
And step S13, loading a plurality of corresponding plug-ins according to the names and the storage addresses of the plug-ins.
Step S20, monitoring the communication link state of the north interface and the comprehensive network management in real time, controlling the state of each plug-in to be in the state required by the communication link state, and the plug-in state including the activation state and the deactivation state, so that the plug-in the activation state performs relevant processing on the notification message received by the north interface.
In this embodiment, the configuration information further records a state required by each corresponding plugin when each type of integrated network manager and northbound interface are in various communication link states. The step S20 specifically processes as follows: and monitoring the communication link state of the northbound interface and the comprehensive network management in real time, and controlling the current state of each corresponding plug-in to be in a state required by the currently monitored communication link state according to the configuration information. The communication link state of the northbound interface and the comprehensive network management comprises the following steps: the communication link connection normal state, the communication link connection failure state and the communication link connection recovery normal state. Namely, when the northbound interface is normally connected with the communication link of the integrated network management, the current state of each corresponding plug-in is controlled to be in the state required when the communication link is normally connected according to the configuration information. And when the connection between the northbound interface and the communication link of the comprehensive network management fails, controlling the current state of each corresponding plug-in to be in a state required by the connection failure state of the communication link according to the configuration information. And when the connection between the northbound interface and the communication link of the comprehensive network management is recovered to be normal, controlling the current state of each corresponding plug-in according to the configuration information to be in a state required when the connection of the communication link is recovered to be normal.
In this embodiment, the operation steps required for monitoring the communication link status between the northbound interface and the integrated network management in real time and controlling the current status of each corresponding plug-in according to the configuration information to be in the currently monitored communication link status include the following two conditions: firstly, monitoring the state of a communication link between a northbound interface and the integrated network management at an initial time point, and secondly, monitoring the state of the communication link between the northbound interface and the integrated network management in a subsequent process at the initial time point. The first case process is as follows: and after the communication link state of the northbound interface and the comprehensive network management is monitored at the initial moment, adjusting the state of each loaded plug-in unit to the state required by the communication link state corresponding to the initial moment according to the configuration information. The second case process is as follows: when the communication link state of the current time point is monitored to be changed compared with the communication link state of the previous time point, all plug-ins in an activated state are adjusted to be in a deactivated state; and then adjusting the state of each plug-in unit to the state required by the scene where the northbound interface is located corresponding to the current moment point according to the configuration information.
In this embodiment, since the initial states of the plug-ins at the initial time point are all the deactivated states, after the communication link state between the northbound interface monitored at the initial time point and the integrated network management system is monitored, only the state of each plug-in needs to be adjusted to the state required by the communication link state corresponding to the initial time point according to the configuration information, that is, only the plug-in needing to be adjusted to the activated state needs to be adjusted to the activated state, and the plug-in needing to be adjusted to the deactivated state keeps the deactivated state unchanged. In the subsequent time of the initial time point, the state of each plug-in unit may be a deactivated state or an inactivated state, so when the communication link state is monitored to be changed at the current time point compared with the previous time point, all the plug-in units in the activated state are firstly adjusted to be the deactivated state; and then adjusting the state of each plug-in to the state required by the scene where the northbound interface is located corresponding to the current moment point according to the configuration information, namely adjusting the plug-ins which need to be adjusted to the activation state from the deactivation state to the activation state.
In the above embodiments, the functions performed by different plug-ins are different. For different types of integrated network management, the plug-ins to be loaded by the northbound interface may be completely different or partially the same. Meanwhile, the northbound interface is applied to a specific integrated network management, and for the communication link state established by the northbound interface and the integrated network management, the plug-ins which need to be activated in different states may be completely different or partially the same.
The method for processing the notification message by the northbound interface comprises the steps of pre-configuring a plurality of plugins and recording configuration information of the corresponding relation between each type of comprehensive network management and the plugin to be loaded through the northbound interface, determining the type of the comprehensive network management establishing a communication link with the northbound interface according to the received notification processing instruction when the notification processing instruction is received, and loading the corresponding plugin pre-configured in the northbound interface according to the type of the comprehensive network management and the configuration information; monitoring the communication link state of a northbound interface and the comprehensive network management in real time, and controlling the state of each plug-in to be in the state required by the communication link state; the plug-in state package activation state and deactivation state, so that the plug-in the activation state can perform relevant processing to the notification message received by the northbound interface, the same plug-in can be applied to different types of integrated network managers, and the activation state of the same plug-in can be applied to different states of a communication link established between the same integrated network manager and the northbound interface, thereby being capable of meeting various requirements of different types of integrated network managers in various states of the communication link established with the northbound interface.
The present invention further provides a northbound interface, and referring to fig. 3, fig. 3 is a functional module schematic diagram of an embodiment of the northbound interface of the present invention. In this embodiment the northbound interface 100 comprises: a setting module 110, a loading module 120 and a control module 130. The setting module 110 is configured to set a plurality of plug-ins and configuration information, where the configuration information records a corresponding relationship between each type of integrated network manager and a plug-in to be loaded. The loading module 120 is configured to determine, according to the received notification processing instruction, an integrated network management type for establishing a communication link with the northbound interface 100, and load a corresponding plugin configured in advance in the northbound interface 100 according to the integrated network management type and the configuration information. The control module 130 is configured to monitor the communication link state between the northbound interface 100 and the integrated network management in real time, and control the state of each plug-in to be in a state required by the communication link state; the plug-in status includes an activated status and a deactivated status, so that the plug-in the activated status performs related processing on the notification message received by the northbound interface 100.
In this embodiment, since the configuration information records the corresponding relationship between each type of integrated network manager and the plug-in to be loaded, the northbound interface 100 can know which plug-ins should be loaded according to the corresponding relationship and the type of integrated network manager establishing a communication link with itself. In addition, in this embodiment, the configuration information records a name and a storage address of each plug-in unit set by the northbound interface 100, and the northbound interface 100 may determine the name and the storage address of the plug-in unit to be loaded according to the configuration information when determining the type of the integrated network management system that establishes the communication link with itself. Referring to fig. 4, fig. 4 is a schematic diagram of a detailed functional module of the loading module in fig. 3. The load module 120 includes: a first determining unit 121, a second determining unit 122, and a loading unit 123. The first determining unit 121 is configured to determine, according to the received notification processing instruction, a comprehensive network management type for establishing a communication link with the northbound interface 100. The second determining unit 122 is configured to scan the configuration information, and determine names and storage addresses of the multiple plug-ins to be loaded according to the configuration information and the comprehensive network management type. The loading unit 123 is configured to load a plurality of corresponding plug-ins according to the determined names and storage addresses of the plurality of plug-ins.
In the above embodiment, the configuration information further records the required state of each corresponding plugin when each type of integrated network manager and the northbound interface 100 are in various communication link states; the control module 130 is further configured to monitor the communication link status between the northbound interface 100 and the integrated network management in real time, and control the current status of each corresponding plug-in according to the configuration information to be in a status required by the currently monitored communication link status. The communication link state between the northbound interface 100 and the integrated network manager includes: the communication link connection normal state, the communication link connection failure state and the communication link connection recovery normal state. Namely, when the communication link connection between the northbound interface 100 and the integrated network management is normal, the current state of each corresponding plug-in is controlled to be in the state required when the communication link connection is normal according to the configuration information; when the connection between the northbound interface 100 and the communication link of the integrated network management system fails, controlling the current state of each corresponding plug-in unit to be in a state required by the connection failure state of the communication link according to the configuration information; when the connection between the northbound interface 100 and the communication link of the integrated network management system is recovered to normal, the current state of each corresponding plug-in is controlled to be in the state required when the connection of the communication link is recovered to normal according to the configuration information.
In the above embodiment, the operation steps required by the control module 130 to monitor the communication link status between the northbound interface 100 and the integrated network management in real time and control the current status of each corresponding plug-in according to the configuration information to be in the currently monitored communication link status include the following two cases: firstly, monitoring the communication link state of the northbound interface 100 and the integrated network management at an initial time point, and secondly, monitoring the communication link state of the northbound interface 100 and the integrated network management in a subsequent process at the initial time point. In the first case, the control module 130 is specifically configured to, after monitoring the communication link state between the northbound interface 100 and the integrated network management at the initial time point, adjust the state of each loaded plugin to the state required by the communication link state corresponding to the initial time point according to the configuration information. In a second situation, the control module 130 is specifically configured to, in the subsequent monitoring process at the initial time point, when it is monitored that the communication link state at the current time point is changed from the communication link state at the previous time point, first adjust all plug-ins in the activated state to the deactivated state; and then adjusting the state of each plug-in to the state required by the scene where the point corresponding to the northbound interface 100 at the current moment is located according to the configuration information.
In this embodiment, since the initial states of the plug-ins at the initial time point are all the deactivated states, after the communication link state between the northbound interface 100 and the integrated network management system is monitored at the initial time point, only the state of each plug-in needs to be adjusted to the state required by the communication link state corresponding to the initial time point according to the configuration information, that is, only the plug-in needing to be adjusted to the activated state needs to be adjusted to the activated state, and the plug-in needing to be adjusted to the deactivated state keeps the deactivated state unchanged. In the subsequent time of the initial time point, the state of each plug-in unit may be a deactivated state or an inactivated state, so when the communication link state is monitored to be changed at the current time point compared with the previous time point, all the plug-in units in the activated state are firstly adjusted to be the deactivated state; and then adjusting the state of each plug-in to the state required by the scene where the point corresponding to the northbound interface 100 at the current time is located according to the configuration information, namely, adjusting the plug-ins required to be adjusted to the activation state from the deactivation state to the activation state.
In the above embodiments, the functions performed by different plug-ins are different. For different types of integrated network management, the plug-ins to be loaded by the northbound interface may be completely different or partially the same. Meanwhile, the northbound interface is applied to a specific integrated network management, and for the communication link state established by the northbound interface and the integrated network management, the plug-ins which need to be activated in different states may be completely different or partially the same.
In the embodiment of the northbound interface 100 provided by the present invention, a plurality of plug-ins and configuration information recording a corresponding relationship between each type of integrated network management and a plug-in to be loaded are preconfigured through the northbound interface 100, when a notification processing instruction is received, the integrated network management type establishing a communication link with the northbound interface 100 is determined according to the received notification processing instruction, and a corresponding plug-in preconfigured in the northbound interface 100 is loaded according to the integrated network management type and the configuration information; monitoring the communication link state of the northbound interface 100 and the comprehensive network management in real time, and controlling the state of each plug-in to be in the state required by the communication link state; the plug-in state package comprises an activated state and a deactivated state, so that in a manner that the plug-in the activated state performs related processing on the notification message received by the northbound interface 100, the same plug-in can be applied to different types of integrated network managers, and the activated state of the same plug-in can be applied to different states of a communication link established between the same integrated network manager and the northbound interface, so that various requirements of the different types of integrated network managers in various states of the communication link established between the integrated network manager and the northbound interface can be met.
The northbound interface of the present invention and its method of handling notification messages will now be further described with a specific first example. The north interface can be applied to the following integrated network management: a-type comprehensive network management, B-type comprehensive network management, C-type comprehensive network management and D-type comprehensive network management. In order to ensure that the northbound interface can be applied to A, B, C, D types of integrated network management, the northbound interface is provided with the following plug-ins: a. b, c, d, e, f, g, h, i, j, k, and setting the relevant configuration information, wherein the configuration information records the following contents: the names and the storage addresses in the northbound interface corresponding to the plug-ins a, b, c, d, e, f, g, h, i, j and k respectively; the plug-ins to be loaded aiming at the north interface of the A-type comprehensive network management are a, e and k; the plug-ins to be loaded aiming at the north interface of the B-type comprehensive network management are a, B, f and i; the plug-ins which need to be loaded aiming at the north interface of the C-type comprehensive network management are h, j, C, e and f; the plug-ins to be loaded aiming at the north interface of the D-type comprehensive network management are a, g, j and D; aiming at the communication link state established by each type of comprehensive network management and the northbound interface, the state required by each corresponding plug-in, for example, when the communication link established by the northbound interface and the type A comprehensive network management is connected normally, a is required to be in an activated state, and e and k are required to be in deactivated states; e needs to be in an activated state when the communication link connection fails, and a and k need to be in a deactivated state; when the communication link connection is recovered to be normal, a and k need to be in an activated state, and e needs to be in a deactivated state. The plug-in a is a JMSSender and is used for converting the notification message received by the northbound interface into a standard JMS message and sending the JMS message to the A-type comprehensive network manager establishing a communication link with the northbound interface. The e-plug is a set-failed Message Storage and is configured to cache the notification Message received by the northbound interface (in order to ensure the time sequence and integrity of the notification Message, the e-plug may further generate a corresponding feature code carrying the reception time of the notification Message according to the notification Message received by the northbound interface, and establish a mapping relationship between the feature code and the notification Message Storage address). The k plug-in is a Notification Loader and is used for loading the Notification message cached by the e plug-in W. The functions of other plug-ins are set according to actual needs, and are not described herein.
When the northbound interface is applied to the A-type integrated network management, namely a communication link is established with the A-type integrated network management, the user only needs to input a notification processing instruction at this time, and the northbound interface firstly determines the type of the integrated network management with which the communication link is established according to the received notification processing instruction; after determining that the integrated network management is the A-type integrated network management, determining plug-ins to be loaded as plug-ins a, e and k according to the configuration information; then, loading operation of the plug-ins a, e and k is executed according to the storage addresses of the plug-ins a, e and k; then monitoring the communication link state established by the northbound interface and the A-type comprehensive network management in real time; and after the communication link state is monitored at the initial time point, the states required by the plug-ins a, e and k corresponding to the communication link state are searched in the configuration information, and the states of the plug-ins a, e and k are adjusted. For example, when the state connection of the communication link is normal at the initial point of time, the plug-in a is adjusted to be in the activated state, and the e and k deactivation states are kept unchanged, so that the plug-in a in the activated state converts the notification message received by the northbound interface into a standard JMS message, and sends the JMS message to the class a integrated network manager which establishes the communication link with the northbound interface. When the communication link connection failure is monitored at the initial time point, the plug-in e is adjusted to be in the activated state according to the configuration information, and a and k are kept in the deactivated state unchanged, so that the plug-in e in the activated state caches the notification message received by the northbound interface. When the communication link connection is monitored to be recovered to normal at the initial time point, the plug-ins a and k are adjusted to be in the activated state according to the configuration information, and the e is kept in the deactivated state unchanged, so that the plug-in k in the activated state loads a notification message cached by the e plug-in, then the notification message is converted into a standard JMS message by the plug-in a, and the JMS message is sent to the A-type comprehensive network manager which establishes the communication link with the northbound interface.
In the subsequent monitoring process of the initial time point, when the communication link state of the current time point is monitored to be changed compared with that of the previous time point, the northbound interface firstly adjusts all plug-ins in the activated state to be in the deactivated state; and then adjusting the state of each plug-in unit to the state required by the scene where the northbound interface is located corresponding to the current moment point according to the configuration information. For example, if the communication link at the previous time point is in a normal connection state and the communication link at the current time point is in a failed connection state, the plug-in a is adjusted to a deactivation state, and the deactivation states of the plug-ins e and k are kept unchanged; and then determining that the plug-ins a and k are in a deactivated state and the plug-in e is in an activated state when the communication link is in a connection failure state according to the configuration information, correspondingly adjusting the plug-ins a and k to be in the deactivated state, and adjusting the plug-in e to be in the activated state, so that the plug-in e caches the notification message received by the northbound interface.
In the present invention, when the northbound interface is applied to other types of integrated network management, the principle of processing the notification message by the northbound interface is the same as the above, and is not described herein again.
In the above example, the functions performed by different plug-ins are different, and the functions of each plug-in are independent from each other, so that the subsequent addition of plug-ins for developing other functions is not affected. Meanwhile, for different types of integrated network managers, the plug-ins required to be loaded by the northbound interface may be completely different or partially the same, that is, the same plug-in can be applied to a plurality of different types of integrated network managers; in addition, the northbound interface is applied to a specific integrated network management, and the plug-ins which need to be in an activated state may be completely different and may be partially the same according to the different states of the communication link established between the northbound interface and the integrated network management, i.e. the same plug-in can be applied to different states of the communication link established between the northbound interface and a certain type of integrated network management, so that the northbound interface in the method for processing the notification message by using the northbound interface and the northbound interface in the integrated network management of different types provided by the invention can be applied to various different types of integrated network management to meet various requirements of different types of integrated network management in various states of the communication link established between the northbound interface and.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
