Fig. 1 is a flowchart of a network device management method according to an embodiment of the present application, where the network device management method in the embodiment at least includes the following steps:
step S110: and acquiring the network equipment information and the protocol adapter information.
In some embodiments, the network device management method is provided by a distributed collaborative services DCS.
In some embodiments, the distributed collaboration service DCS dynamically monitors the resource database through the message middleware to acquire creation and deletion of network device information.
In some embodiments, the distributed collaboration service DCS actively acquires creation and deletion of network device information through an interface.
In some embodiments, the distributed collaboration service DCS is able to listen to the creation and deletion of protocol adapter instances.
By acquiring the information of the network equipment and the information of the protocol adapter in real time, the network equipment is dynamically allocated to the protocol adapter for management, so that the network equipment is more accurately and timely allocated relative to the protocol adapter, a routing table can be accurately and timely updated, and the smoothness of a communication link is ensured.
Step S120: and establishing a mapping relation between the network equipment and the protocol adapter according to a preset algorithm.
In some embodiments, the eligible protocol adapter instances are mounted under distributed nodes of the distributed collaborative services architecture, and thus the mapping between the network device and the protocol adapter PA essentially represents the mapping between the network device and the distributed nodes of the distributed services architecture.
In some embodiments, the protocol adapter PA carries an algorithm packet during registration, the algorithm packet includes a preset algorithm for network device allocation, and the distributed cooperative service DCS may perform the network device allocation according to the algorithm in the algorithm packet.
In some embodiments, the protocol adapter PA does not specify an algorithm at registration, and therefore The distributed collaborative service DCS has a default algorithm, the Least Priority algorithm and The equipartition algorithm, respectively. Those skilled in The art know The specific meanings of The Least Priority algorithm and The averaging algorithm, and therefore, the detailed description thereof is omitted here.
Step S130: and updating a routing table according to the mapping relation, wherein the routing table is used for establishing communication between the application and the network equipment.
In some embodiments, the distributed collaboration service DCS dynamically assigns network devices to protocol adapters for management, updating routing tables. It is worth noting that if it is the first update, it is equivalent to creating a routing table. The routing table is capable of establishing indirect communication between the application and the network device.
According to the method and the device, the network devices of different protocol types can be distributed to the corresponding protocol adapters for management in a distributed scene, and the routing table is updated, so that the network devices of different protocol types can be correctly addressed, and upper-layer applications can interact with the network devices of different protocol types and are isolated from the network devices; the method eliminates the difference between the network devices with different protocol types, can realize the dynamic addition of the network device types without influencing the original framework, and achieves the purposes of self-adapting and high-efficiency management of the network devices.
Another embodiment of the present application will be described in detail below with reference to fig. 2.
Fig. 2 is a flowchart of a network device management method according to another embodiment of the present application, including at least the following steps:
step S111: dynamically monitoring the creation and deletion of network equipment information through message middleware; the creation and deletion of the protocol adapter instance is snooped.
The message middleware utilizes an efficient and reliable message transmission mechanism to carry out asynchronous data transmission, carries out integration of a distributed system based on data communication, and can extend communication among processes in a distributed environment by providing a message queue model and the message transmission mechanism.
Step S121: and the protocol adapter instance exists and has network equipment management capability, and the protocol adapter instance is mounted to distributed nodes of the distributed collaborative service architecture.
In some embodiments, the protocol adapter that determines the protocol type has been successfully registered, and the protocol adapter instance corresponding to the protocol type has been created and is valid, and the specific registration process is described in the following embodiments. The protocol adapter instance needs to be mounted under the distributed nodes of the distributed service architecture to implement specific operation and management of the network device.
Step S122: and distributing the network equipment to distributed nodes for management according to an equipartition algorithm.
In some embodiments, other algorithms may be employed to assign network devices, such as The Least Priority algorithm, and The like.
In some embodiments, the distributed cooperative service DCS acquires the designated algorithm packet through the interface provided by the southbound protocol adaptation manager, and loads and executes the designated algorithm packet, calculates the allocation result, and allocates the network element and the network device thereof to the corresponding protocol adapter instance node.
Step S131: and updating a routing table according to the mapping relation between the network equipment and the protocol adapter, wherein the routing table is used for establishing communication between the application and the network equipment.
In some embodiments, the routing table is updated based on an assignment of the distributed collaborative services DCS to the network device with respect to the protocol adapter instance. It is worth noting that if it is the first update, it is equivalent to creating a routing table. The routing table is capable of establishing indirect communication between the application and the network device.
According to the method and the device, the accessed network devices of different protocol types can be distributed to the corresponding protocol adapters for management in a distributed scene, and the routing table is updated, so that the network devices of different protocol types can be correctly addressed, and an upper layer application can be isolated from the network devices while interacting with the network devices of different protocol types; the method eliminates the difference between the network devices with different protocol types, can realize the dynamic addition of the network device types without influencing the original framework, and achieves the purposes of self-adapting and high-efficiency management of the network devices.
Fig. 3 is a flowchart of a network device management method according to another embodiment of the present application, which includes at least the following steps:
step S112: acquiring the creation and deletion of network equipment information through an interface; the creation and deletion of the protocol adapter instance is snooped.
In some embodiments, the distributed collaboration service DCS is able to directly obtain network device information through the interface.
Step S123: and if the protocol adapter instance does not exist, the network equipment is distributed to the cache nodes of the distributed service architecture by default for management.
In some embodiments, there may be no protocol adapter instance due to unsuccessful registration of a protocol adapter, and in this case, in order to implement management of the network device, the network device needs to be allocated to a cache node of the distributed service architecture for management, and when a qualified protocol adapter instance appears, the network device needs to be reallocated and transferred again, which enables the entire distributed service architecture to be more flexible, and makes it more reliable, usable, and efficient to access. It should be noted that when the network device is mounted on the cache node, no communication is performed, and only after a new instance is registered, the network device is allocated to the registered instance from the cache node and performs communication again.
Step S132: and updating a routing table according to the mapping relation between the network equipment and the cache node, wherein the routing table is used for establishing communication between the application and the network equipment.
In some embodiments, the routing table is updated according to an allocation result of the distributed cooperative service DCS to the network device with respect to the cache nodes of the distributed service architecture. It is worth noting that if it is the first update, it is equivalent to creating a routing table. The routing table is capable of establishing indirect communication between the application and the network device.
The network equipment management method provided by the embodiment of the application is suitable for the specific application scene that the protocol adapter instance is not successfully created, the network equipment is more flexibly managed, the whole distributed service architecture is more elastic, and the reliability, the availability and the access efficiency are higher.
Fig. 4 is a flowchart of a network device management method according to another embodiment of the present application, which includes at least the following steps:
step S112: acquiring the creation and deletion of network equipment information through an interface; the creation and deletion of the protocol adapter instance is snooped.
In some embodiments, the distributed collaboration service DCS is able to directly obtain network device information through the interface.
Step S124: and the number of the network equipment managed under the protocol adapter instance reaches a threshold value, and the network equipment is distributed to the cache nodes of the distributed cooperative service architecture for management according to a preset algorithm.
In some embodiments, after the protocol adapter PA is successfully registered, the protocol adapter instance may be created, and at this time, multiple protocol adapter instances may be created at a time, and the maximum number of network devices that can be managed by each instance, that is, a threshold, is set in advance, so as to improve the management efficiency of the network devices. When the number of the network devices managed under a specific protocol adapter instance reaches a threshold value, the instance does not have the management capability, and therefore the network devices are distributed to the cache nodes of the distributed collaborative service architecture for management.
In some embodiments, when some instances release some network devices and enable the protocol adapter instance meeting the conditions, the re-allocation and transfer are performed, which can make the whole distributed service architecture more flexible, and make it more reliable, available and access efficient.
Step S132: and updating a routing table according to the mapping relation between the network equipment and the cache node, wherein the routing table is used for establishing communication between the application and the network equipment.
In some embodiments, the routing table is updated according to an allocation result of the distributed cooperative service DCS to the network device with respect to the cache nodes of the distributed service architecture. It is worth noting that if it is the first update, it is equivalent to creating a routing table. The routing table is capable of establishing indirect communication between the application and the network device.
The network equipment management method provided by the embodiment of the application is suitable for a specific application scene that the management quantity of the network equipment exceeds a threshold value in a protocol adapter instance, on one hand, the network equipment management efficiency is improved, on the other hand, the network equipment management reliability is ensured, and a large amount of asynchronous messages can be quickly responded.
In some other embodiments of the present application, it may also happen that the protocol adapter does not have the management capability for the network device due to the broken link of the protocol adapter instance, and the principle is the same as that in the above embodiments, at this time, the network device is allocated to the cache node of the distributed collaborative service architecture for management, waits for a suitable condition, and then is reallocated.
In some other embodiments of the present application, when the network device information is deleted, the network device is deleted from the distributed node where the protocol adapter is located.
In some other embodiments of the present application, when the network device is disconnected, the protocol adapter may autonomously select whether to establish a link with the network element device.
The change of the mapping relation can cause the updating of the routing table, so that the application App can establish communication with the network equipment according to the routing table dynamically updated in real time. Because the application App establishes the link with the network equipment through the protocol adapter, the network equipment with different protocol types can be accessed into the framework for management in a unified mode, and therefore, the original module can not be influenced by dynamically adding new network equipment types, and the purpose of adaptively managing the network equipment is further achieved.
An embodiment of the present application further provides a protocol adapter management method, as shown in fig. 5, including at least the following steps:
step S210: protocol adapter information is received, the protocol adapter information including protocol type information.
In some embodiments, the protocol adaptation manager is responsible for managing the protocol adapters based on protocol type information provided by the protocol adapters.
Step S220: and registering the protocol adapter to the protocol adaptation manager according to the protocol type information.
In some embodiments, the protocol adapter sends the algorithm packet carried by itself and the related information of the protocol type of itself to the protocol adaptation manager to complete the registration operation.
In some embodiments, the protocol adapter itself has no algorithm package or assigned algorithm, and therefore, may rely on The default algorithms that The distributed collaborative service DCS has, namely The Least Priority (The Least Priority) algorithm and The equipartition algorithm.
It is noted that, as known to those skilled in the art, the registration, the cancellation, the modification and the query of the protocol adapter are all external functions of the protocol adaptation manager, which can provide corresponding functions based on the requirements of the distributed cooperative service DCS and other services.
In some embodiments, the protocol adaptation manager further has functions of establishing a link for implementing the protocol adapter instance, acquiring network device information, monitoring a link state, monitoring a network element state, and the like.
Step S230: and according to the network equipment management method, managing the network equipment which has the mapping relation with the protocol adapter.
In some embodiments, after the protocol adapter type registration is successful, the protocol adapter instance PA may be created, at this time, a plurality of protocol adapter instances may be created at a time, and the maximum number of network devices that can be managed by each instance, that is, a threshold value, is set in advance, so as to improve the management efficiency of the network devices.
In some embodiments, management of network devices is achieved by mounting instances created by protocol adapters under distributed network nodes.
In some embodiments, the protocol adaptation manager is located in the southbound access stratum, and the management of the network devices is realized together by matching with a network device management method implemented by a distributed cooperative service DCS.
The protocol adapter management method provided by the embodiment of the application is applied to a protocol adapter manager, and realizes the link establishment of a protocol adapter instance, the acquisition of network equipment information, the monitoring of a link state and the monitoring of a network equipment state through the management of a protocol adapter registered under the protocol adapter, and finally realizes the shielding of differences among various network equipment, so that an upper application can communicate and interact with the network equipment, and the protocol adapter upwards exposes a uniform interface through a southbound access framework.
The embodiment of the application also provides a communication method, in particular to a communication forwarding technology.
In some embodiments, it determines the target protocol adapter address by receiving a communication request sent by an application and according to the communication request and a routing table, where the routing table is obtained by the network device management method in the above embodiments. The essence of the communication is to establish a communication connection with the network device, but due to the difference of protocols, the forwarding is performed through the protocol adapter, so that the protocol adapter of the target needs to be addressed. And the communication mode can realize decoupling between the upper application App and the network equipment.
