Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic block diagram of a network system to which an embodiment of the present invention is applicable.
As shown in fig. 1, the network system 100 includes a network management device 102 and at least one network device 104. For example, as can be seen in fig. 1, in this implementation, the network device 104 includes a camera, a smart phone, and a modem. It should be understood that the network device 104 is not limited to the devices shown in fig. 1. In particular, network device 104 includes enterprise service platforms, network infrastructure devices, and other networking devices that are managed by the carrier's configuration that provide interconnections across networks that are organized in different networking manners.
The network management device 102 is a device operated by an operator, and is capable of managing each network device 104 that is accessed. The network management device 102 illustratively has a network management system 1022 running therein, where the network management system 1022 may be a computer software system, a hardware system, or a combination of software and hardware systems, for managing each network device accessing the network management system.
In the embodiment of the application, in order to realize that each network device accessed by the network management system is managed, the network management device needs to acquire the link state of each network device accessed to the network management system, determine the unsuccessful network device to be accessed by the network management system based on the acquired link state, and then reconstruct the link with the network device to be accessed based on the preset link reconstruction strategy, so as to ensure that each network device successfully accesses to the network management system, realize that the network management system manages each access network device, effectively prevent the high delay problem of fault location when a plurality of network devices have link faults at the same time, further realize that the network management system manages each access network device, and effectively ensure the stability of each network device in the access network management system.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating an implementation of a network device access management method according to an embodiment of the invention. The network device access management method may be implemented by the network management device shown in fig. 1. In particular, the implementation may be performed by hardware or software of a network management device.
As shown in fig. 2, the network device access management method includes steps S201 to S203. The details are as follows:
s201, obtaining the link state of each network device accessing the network management system.
The network equipment can establish a link between the preset protocol type and the network management system, and after the link is established successfully, the network equipment is accessed to the network management system so as to realize communication between the network management system and the network equipment.
In particular implementations, the network management system provides registration functionality for network device registration related parameters that access the network management system so that the network device can be taken over by the network management system, e.g., the network device registration related parameters include: access IP address, access port, access username, access password, etc.
The network management system initiates a link establishment request, such as an SSH request, a TLS request, etc., to the corresponding network device by acquiring registration parameters of the network device, and prepares to establish a link. Messages based on protocols such as TCP, UDP, etc. may also be sent.
In the embodiment provided by the invention, in the process that the network equipment is accessed to the network management system, the link state of each network equipment accessed to the network management system is detected, so that when the link is abnormal, the link is timely rebuilt, the link between the network equipment and the network management system is ensured to be smooth, and further, the network management system is ensured to perform tasks and issue and the network equipment is ensured to report information timely.
Specifically, the network management system provided by the embodiment of the invention supports the network equipment access of the network configuration protocol (Network Configuration Protocol, netconf), and can be used as a client to initiate a Secure Shell protocol (SSH) request or a Secure transport layer protocol (TLS) request to the corresponding network equipment to be accessed, so as to achieve the purpose of establishing a link with the network equipment. When the network management system initiates a link establishment request, an access user name and an access password are required to be carried, so that the access security of the network equipment is ensured. Specifically, when the link is established, the establishment of the SSH or TLS link is completed through 3 processes; then, a subscription notification message customized based on a preset protocol is sent to the network equipment so as to realize the notification message of the subscription network equipment; and finally, sending a self-defined capability message to the network equipment for judging whether the network equipment is accessed to the network management system or not so as to prevent the network equipment from being accessed to other pre-deployed network management systems and being incapable of being managed by the network management system. After the SSH or TLS link establishment is completed between the network management system and the network equipment, and the notification message subscribed to the network equipment and the custom capability message sent to the network equipment are successful, the link establishment between the equipment management system and the network equipment is determined to be successful, otherwise, the link establishment fails.
In this embodiment, the link state of each network device of the network management system and the access network management system may be detected based on a preset timing detection policy during the process of accessing the network device to the network management system, so as to determine whether the link between the network management system and the accessed network device is available, so as to ensure that the link between the network management system and the network device is kept alive, further achieve stability of communication between the network management system and the network device, and avoid that the network device cannot be managed by the network management system due to interruption of communication between the network management system and the network device.
Specifically, the preset timing detection strategy includes: heartbeat detection timing policy and link detection timing policy.
In an embodiment, detecting a link state of each network device accessing the network management system based on a preset timing detection policy includes: based on a preset heartbeat detection timing strategy, respectively detecting the data transmission condition between the network management system and each network device; and analyzing the data transmission condition between the network management system and each network device based on a preset link detection timing strategy to obtain the link shape of each network device accessed to the network management system. The link state of each network device accessed to the network management system is determined according to the data transmission condition between the network management system and each network device, so that the stability of the link connection between the network management system and each network device is ensured according to the link state, and the abnormality detection can be timely carried out when the link is abnormal.
The method for determining the stability of the link between the network management system and each network management device comprises the steps of: sending heartbeat messages to each network device at a first time interval through the network management system to determine whether the link between each network device and the network management system is abnormal; and aiming at network equipment with abnormal links, determining a second time interval for sending heartbeat information to each network equipment according to a preset algorithm so as to detect the link stability between the network management system and each network equipment.
In implementation, assuming that the first time interval is T, the network management system performs sending a heartbeat message to the network device every T seconds, where the value of T may be preset, for example, default may be set to 90s.
And when the link between the network equipment and the network management system is abnormal, determining a second time interval for transmitting the heartbeat information according to a preset algorithm. In particular, the second time interval may be expressed as:
t＝T/2 n-1
Wherein T is an initial preset first time interval, n is the number of times of sending heartbeat information, and T is a second time interval.
In particular implementations, t is an integer value and greater than 0. For example, in one embodiment, assume t=90 s, n=1, 2, 3, 4; a heartbeat message is sent to the network device at second time intervals of t=90 s, 45s, 23s and 12s, respectively, when an abnormality occurs in the link.
In an embodiment, detecting a link connection state between a network management system and each network device based on a preset link detection timing policy, respectively, includes: and determining the link connection state between the network management system and the network equipment according to the link maintenance time between the network management system and the network equipment, the time when the network management system receives the uplink message last time and the current time aiming at any network equipment.
For example, assume that the link retention time between the network management system and any network device is t1, the time when the network management system last received the uplink message is t2, the current time is t3, when t2-t3> t1, it indicates that the link connection state between the network management system and the network device is abnormal, or when t2-t3 is less than or equal to t1, it indicates that the link connection state between the network management system and the network device is normal. It should be understood that when an abnormality occurs in the link connection state between the network management system and the network device, the network management system is required to close the link already established with the network device and to resume the link connection.
S202, determining network equipment to be accessed, which needs to be connected with the network management system again in a link mode, based on the acquired link state.
In an embodiment, determining, based on the obtained link state, a network device to be accessed that needs to be re-linked with the network management system includes: if the link connection between the network equipment and the network management system is unstable or the link connection state is connection failure, determining the network equipment as the network equipment to be accessed, which needs to be connected with the network management system again.
And S203, carrying out link reestablishment with each network device to be accessed based on a preset link reestablishment strategy.
In an embodiment, performing link reestablishment with each network device to be accessed based on a preset link reestablishment policy includes: the network management system initiates a reestablishment chain request to each network device to be accessed respectively, and adds the reestablishment chain request into a reestablishment chain task queue; based on the reconstruction chain delay rule, respectively delaying to reconstruct the link with each network device to be accessed.
Specifically, the reconstruction chain delay rule includes: after each link establishment failure, the link establishment is delayed, and the time length of the corresponding delay execution is increased according to a preset rule along with the increase of the number of link establishment times.
When the method is implemented, after the link establishment of the network management system and the network equipment fails, the network management system needs to initiate a reestablishment link request to the network equipment, add the reestablishment link request into a reestablishment link task queue, and control the reestablishment link task to be executed in a delayed manner based on a reestablishment link delay rule; specifically, the delay time gradually increases with the number of times of chain establishment, and it is assumed that the delay time increases by T0 seconds every time of chain establishment, and the waiting time of n times of chain establishment reconnection t0=t0×n (n-1)/2. Setting the timeout time of each link establishment failure to be T1 seconds, and setting the total timeout time from the beginning of the first link establishment failure to the nth link establishment to be t1= (n-1) T1, wherein the total time length of the nth link establishment relative to the first link establishment is as follows:
T＝T0+T1
assuming t0=10s, t1=10s, the total duration t=t0+t1=20s of the second construction with respect to the first construction, the total duration t=t0+t1=50s of the third construction with respect to the first construction, and the total duration t=t0+t1=90s of the fourth construction with respect to the first construction.
Specifically, as shown in fig. 3, fig. 3 is a schematic diagram of a timeout reestablishing chain connection according to an embodiment of the present invention.
In the implementation, assuming that n network devices have overtime of link establishment, the overtime time of link establishment failure of each network device is t1 seconds, and m tasks are started to initiate link establishment, the worst time of one link establishment attempt of all network devices is n×t1/m. If a total of 120 network devices access the device management system, 120 links are established over time, the time-out time is 10s, 32 tasks are started to establish links, and the worst time is 120 x 10/32=37.5 seconds.
In addition, in the embodiment of the present application, the link state between each network device to be accessed and the network management system needs to be uploaded to the user side, so that the user can conduct link abnormality checking based on the link state of each network device to be accessed. Specifically, after link reestablishing with each network device to be accessed based on a preset link reestablishment policy, the method further includes: and reporting the link states between the network equipment to be accessed and the network management system to the user side respectively so that the user can conduct abnormal link checking based on the link states of the network equipment to be accessed, wherein the link states carry the reasons of link establishment failure.
The link abnormality investigation is a means for detecting link abnormality of a link between the network management system and the network equipment after the network equipment is accessed to the network management system, and aims to realize maintainability and testability of the network management system on link management so as to present the reason of the link abnormality to a user side in time, facilitate the user to examine and solve the problem in time and improve the operation and maintenance efficiency. Specifically, the link abnormality detection mainly includes: detecting whether a network between the network management system and the network equipment is available, detecting whether the network equipment has the capability of being managed by the network management system, detecting whether an authenticated access user and an access password are correct when the network management system initiates a link establishment request to the network equipment, and the like. When the link is abnormally closed, the network management system reports the link state of the access network equipment and the reason of the link abnormality diagnosis to an upper user at the same time, so that the user can find out the equipment link abnormality in time and acquire the reason for investigation and solution.
Specifically, the reason of the link establishment failure can be determined by performing abnormality diagnosis on links between each network device to be accessed and the network management system; in this embodiment, before reporting the link status of each network device to be accessed to the user end, the method includes: and respectively carrying out abnormal diagnosis on links between the to-be-accessed network equipment and the network management system, and determining the cause of the link establishment failure between the to-be-accessed person equipment and the network management system.
As can be seen from the above analysis, in the network device access management method provided by the embodiment of the present invention, by acquiring the link state of each network device accessing the network management system, determining the network device to be accessed that needs to be connected with the network management system again based on the acquired link state, so as to solve the problem of high delay in performing fault location when a plurality of network devices have link connection faults at the same time, and performing link reconstruction with each network device to be accessed based on a preset link reconstruction policy, so as to ensure that each network device accesses the network management system, realize management of each access network device by the network management system, and effectively ensure stability of each network device accessing the network management system.
Referring to fig. 4, fig. 4 is a schematic flow chart illustrating an implementation of a network device access management method according to another embodiment of the present invention. Compared with the embodiment shown in fig. 2, the implementation procedure of S401 to S403 is the same as the implementation procedure of S201 to S203, except that S404 to S406 are further included after S403, as follows:
s401, obtaining the link state of each network device accessing the network management system.
S402, determining network equipment to be accessed, which needs to be connected with the network management system again in a link mode, based on the acquired link state.
S403, carrying out link reestablishment with each network device to be accessed based on a preset link reestablishment strategy.
S404, acquiring network equipment resource identification information carried by the command to be issued, and determining target network equipment based on the network equipment resource identification information, wherein the target network equipment is used for receiving the command to be issued.
In specific implementation, the network device resource identification information carried by the command to be issued can be acquired through a preset interface, such as an representational state transition interface (Representational State Transfer, restful). The network management system searches corresponding target network equipment based on the acquired network equipment resource identification information so as to quickly send the command to be sent down to the target network equipment.
S405, determining the type of the message carried by the command to be issued, and judging the type of a message channel required for transmitting the command to be issued based on the type of the message.
In particular implementations, the network management system may pre-create two message channels, e.g., one channel to support single network device serial messages and the other channel to support multiple network device parallel messages. That is, the message channel types include single-element serial message channels or multi-element parallel message channels. And judging whether parallel or serial issuing to the network equipment is required to be supported by acquiring the message type carried by the command to be issued, and searching a corresponding message channel according to the judging result to issue the command or the message to the network equipment. So as to realize the smooth issuing of the message.
S406, selecting a message channel corresponding to the message channel type, and issuing the command to be issued to the target network equipment.
In this embodiment, the message forwarding is mainly used to execute the operation of issuing the command to the network device, and according to the execution modes of different issuing commands, the single network device serial message and the multi-network device parallel message can be respectively selected to be executed, so that the issuing command can be conveniently and quickly executed, and the response message of the network device can be timely obtained. When the network management system executes the issuing command, the network management system carries the resource identifier of the network equipment, finds the accessed network equipment according to the resource identifier, and judges whether the issuing command goes through the serial queue or the parallel queue according to the message type carried by the issuing command. In order to achieve timely and rapid response of the message, a response timeout time of the message can be set.
In addition, the network management system can also terminate the execution of the command to be issued if the execution of the command to be issued is detected to be overtime; and acquiring response information returned by the target network equipment, and reporting the response information to the user side.
The method comprises the steps of reporting response information, subscribing information which needs to be actively reported by network equipment, receiving notification information reported by the network equipment and then sending the notification information to a message user side when a network management system operates, and reading the response information returned by the network equipment from the reported information by the user side so as to determine the link connection state between the network equipment and the network management system according to the response information, thereby further rapidly positioning faults.
As is apparent from the above analysis, the network management system provided by the present invention can perform link management and message management at the same time, and specifically, the process of performing link management and message management by the network management system can be implemented by executing a computer program, and the network management system can be logically divided into a plurality of modules having different functions, and the functions of each module are implemented by reading and executing instructions in a memory by a processor in the network management device.
