Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments herein without making any creative effort, shall fall within the scope of protection.
It should be noted that the terms "first," "second," and the like in the description and claims herein and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments herein described are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, apparatus, article, or device that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or device.
When network equipment is accessed to a network, the configuration cost is high and the period is long due to the fact that the number of the equipment is large, the deployment is scattered and professional staff are required to go to the site for support, and the configuration cost is high and the period is long, so that the configuration cost becomes an important factor for limiting the simplification of a deployment process and limiting the deployment efficiency. Reducing the operation and maintenance management intensity of the end side is particularly important for improving the operation and maintenance efficiency of network equipment of a network node, wherein the maintenance workload is obviously reflected in the operation of opening bureaus such as the installation and the configuration of the network equipment. In the prior art, although the zero-contact configuration opening method is adopted, the problems of safety, complex operation and the like of the existing zero-contact configuration opening method still exist due to the fact that a transmission medium has safety risks, opening field requirements and high technical threshold, manual operation exists and the like.
In order to solve the above problems, embodiments herein provide a zero-contact configuration opening method and apparatus, a computer device, and a storage medium, which can simplify a network device deployment process, improve network device deployment efficiency, reduce a technical threshold for opening a network device at a network point, and reduce workload of an operation and maintenance staff for opening an office. It should be noted that the zero-touch configuration issuing method, the zero-touch configuration issuing device, the computer device and the storage medium provided herein may be used in the financial field, and may also be used in any field other than the financial field. Fig. 1 is a schematic diagram of the steps of a method for opening a zero-contact configuration provided in the embodiments herein, and the present specification provides the method operation steps as described in the embodiments or flowcharts, but may include more or less operation steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. When an actual system or apparatus product executes, it can execute sequentially or in parallel according to the method shown in the embodiment or the figures. Specifically, as shown in fig. 1, the method is applicable to a network device (i.e., a user-side device to be configured with zero touch), and the method may include:
s110: sending a zero-contact configuration request to a server through relay equipment, wherein the zero-contact configuration request comprises identity authentication information;
the authentication information may include a unique identification Serial Number (SN) of the network device, and the authentication information may further include information such as a port Number of the network device and an IP address of the downstream router.
S120: receiving link information matched with the identity authentication information returned by the server through the relay equipment;
it should be noted that, in the embodiment of the present specification, the server integrates the functions and functions of a DHCP server and a file server. After receiving a zero-contact Configuration request sent by a network device through a relay device, a server selects an IP address (and a corresponding subnet mask) from IP addresses that are not leased (i.e., not occupied) to allocate to a network device with a legal identity based on a Dynamic Host Configuration Protocol (DHCP), and allocates information of a file server corresponding to a Configuration file required for zero-contact Configuration of the network device (including information of a URL of the file server, i.e., a Uniform Resource Locator, etc.). That is, the link information includes an IP address of the network device, a subnet mask, and the like, and information related to the file server, and the link information may further include other setting amount information.
Besides, the network device may receive other configuration information returned by the server through the relay device, for example, file information (including a file name, a file number, file version information, and the like) of a desired configuration file.
S130: establishing a file transmission link with the server according to the link information;
namely, according to the link information, the network device establishes a file transmission link with the server.
S140: receiving a configuration file which is returned by the server through the file transmission link and matched with the identity authentication information;
namely, the server issues the configuration file based on a CPE wide area network Management Protocol (CWMP) Protocol, so as to solve the problem that the opening operation and maintenance of a Customer Premise Equipment (CPE) device (i.e., the network device described herein) is difficult, save the maintenance cost, and improve the opening deployment efficiency.
Namely, the authentication information is not only used for matching the link information, but also used for issuing the corresponding configuration file, so that the network equipment side does not need to send the authentication information for multiple times, and the operation flow of the network equipment side is simplified. The configuration files include system software, configuration files, License files, patch files, custom files, and the like required by the network device for opening, and it should be noted that the configuration files may be different for different network devices.
S150: and opening the zero-contact configuration according to the configuration file.
In the zero-contact configuration opening method provided in the embodiments of the present specification, when a network device and a server of the zero-contact configuration opening perform simple message interaction (send a zero-contact configuration carrying identity verification information) only through a relay device, a file transmission link can be established with the server to obtain a configuration file required by the zero-contact configuration, thereby completing the zero-contact configuration opening, and greatly simplifying a network device opening deployment process; the efficiency of opening the zero-contact configuration of the network equipment is improved; the operator only needs simple operation, which reduces the technical threshold of network equipment operation and reduces the working intensity of the operator. In addition, in the embodiment of the specification, the security of file transmission is improved by establishing a file transmission link and then issuing a configuration file.
In the embodiment of the present specification, on one hand, since the network device may not know the number of IP addresses that the server has not leased yet and whether the IP addresses managed by the unknown server side are adapted to itself, the network device may send a zero configuration request to the plurality of servers through the relay device, so as to improve timeliness and success rate of response to the zero contact configuration request. Alternatively, the server may send multiple link information (e.g., multiple, non-leased, IP addresses adapted to the network device, and/or information of multiple file servers adapted to the network device) for selection by the network device, such that more than one link information may be received by the network device.
Therefore, at step S130: before establishing a file transmission link with the server according to the link information, the method further includes:
judging whether the received link information is unique or not;
if the link information is unique, establishing a file transmission link with the server according to the link information;
and if the link information is more than one, selecting one of the link information according to a preset screening rule, and establishing a file transmission link according to the screened link information and the server.
In some possible embodiments, the preset screening rule may be according to the receiving sequence of each link information, that is, the network device may establish a file transmission link with a server corresponding to the first received link information.
Preferably, as shown in fig. 2, in the embodiment of the present specification, in step S130: before establishing a file transmission link with the server according to the link information, the method further includes:
s210: transmitting a link information confirmation request to the server through the relay device;
the confirmation request carries link information to be confirmed;
it should be noted that, if the link information received by the network device is unique, the link information to be confirmed here is the link information received in the foregoing step;
since the network device may receive a plurality of link information from the same server or different servers, if the link information received by the network device is not unique, the link information to be confirmed here is the link information screened according to the preset screening rule.
S220: and receiving confirmation information corresponding to the confirmation request returned by the server through the relay equipment so as to establish a file transmission link with the server.
When receiving the confirmation information returned by the server, the network device indicates that the link information to be confirmed is available, and the network device can successfully establish a file transmission link with the server according to the link information to be confirmed and enable the server to recover other link information once provided.
In some possible embodiments, the method further comprises:
and when receiving the negative confirmation information corresponding to the confirmation request returned by the server through the relay equipment or not receiving the confirmation information returned by the server within a first preset time limit, judging that the link information to be confirmed can not be used.
If the link information to be confirmed is not available, different processing measures can be taken according to the number of the received link information in the previous steps:
if the received link information is unique, a zero-contact configuration request is initiated again through the relay equipment;
if more than one link information is received, another link information is selected from the multiple link information (for example, the second received link information is selected, that is, the next link information is selected according to the receiving sequence of the link information), and a link information confirmation request is sent to the server through the relay device again. Under the scene, the network equipment can be prevented from repeatedly initiating the zero-contact configuration request for many times, the process is simplified, and the processing efficiency is improved.
The method steps meet the requirement of confirming whether the file transmission link is successfully established between the network equipment and the server under various scenes, and provide a countermeasure when the file transmission link is not successfully established.
And if the confirmation request or the zero-contact configuration request is transmitted for a plurality of times in an accumulated manner (for example, three times or more), and the confirmation information of the link information fed back by the server is still not received, transmitting alarm information to an operation and maintenance person who opens an office, and reminding the operation and maintenance person to check the network equipment, the relay equipment and the server.
In step S110: before sending the zero-touch configuration request to the server through the relay device, the method further includes:
acquiring information of a plurality of alternative relay devices and architecture information between each alternative relay device and a server;
and selecting one of the candidate relay devices as the relay device according to the information of the candidate relay devices and the architecture information.
In the banking field, the server, the relay device and the network device may adopt a flat architecture or a non-flat architecture, or an architecture in which a flat architecture and a non-flat architecture are mixed.
The network topology in the flat architecture is: the system comprises a server, network equipment of a first-level branch and network equipment of each network point, wherein the first-level branch is a local branch which is established by taking province level as a unit and is mainly responsible for overall planning and administrative management of all (or most) branches governed by the whole province.
Because the number of the first-level branch lines is limited, when network equipment of the first-level branch lines is deployed in an opening, a traditional mode of utilizing transmission media such as a U disk and mails can be adopted; when the network devices of the mesh points are subjected to zero-contact configuration opening, because the mesh points are numerous, the network devices of the primary branch lines are required to serve as relay devices to perform zero-contact configuration requests and forward link information.
The network topology structure of the non-flat architecture is as follows: the system comprises a server, a first-level branch network device, a second-level branch network device and a network device of a network point, wherein the second-level branch is established by taking the city level as a unit.
The zero-contact configuration method of the first-level branch network equipment in the non-flat architecture can be consistent with the configuration opening method in the flat architecture; when zero-contact configuration opening is carried out on the network equipment in the secondary branch, the network equipment in the primary branch is used as relay equipment; and when the network equipment of the network point is opened and deployed, the network equipment of the second-level branch is selected as the relay equipment. The global network equipment is deployed in the layer-by-layer progressive mode, so that mistakes and omissions can be avoided.
In the architecture in which the flat architecture and the non-flat architecture are mixed, the deployment of the network device is a combination of the deployment manners of the two architectures, and details are not repeated here.
Therefore, the zero-contact configuration issuing method provided by the embodiment of the specification can meet the issuing configuration requirements of network equipment under different architectures in a bank financial system. The network equipment of different levels is used as the relay equipment, so that the service pressure of each relay equipment can be reduced.
The zero-contact configuration opening method provided by the embodiment of the present specification further includes:
judging whether the link information (mainly the IP address issued by the server to the network equipment) reaches a preset service life and judging whether the zero-contact configuration opening is finished;
if the link information expires and the zero-contact configuration opening is not completed, sending a continuing request of the link information to a server so as to prolong the service life of the link information;
if the zero-contact configuration opening of the network equipment is completed, the network equipment does not initiate a zero-contact configuration request according to the closing of the DHCP function; and returning the link information to the server so that the server recycles the link information to provide the zero-touch configuration service for other network devices again.
Preferably, in order to avoid the influence of the expiration of the link information on the zero-contact configuration opening of the network equipment, the network equipment preferably starts to time when a file transmission link is established with the server, and automatically sends a request for prolonging the service life to the server when the service life of the link information exceeds half. And after the service life is successfully prolonged, restarting the timing by using the updated node of the service life.
