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 given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the embodiment of the present invention, an EMS (Element Management System), hereinafter referred to as a network Management System, is used to implement Management of network elements in a network System, and reduce a manual configuration process of the network elements, thereby improving network Element Management efficiency and reducing equipment maintenance cost of an operator. This process is explained in detail below.
The embodiment of the invention provides a method for managing network elements in a network system, which specifically comprises the following steps:
in a scenario of opening an office of a telecommunication device, information that a new network element is to be started in the office is pre-stored in an EMS, and generally, when a new office is opened, the EMS needs to store information of a plurality of new network elements, where the information of the network elements includes: the corresponding relation between the configuration data and the identification information of the network element and the physical characteristic information of the network element.
After a new network element is powered on, a registration request is sent to an EMS (energy management system), the registration is to enable the EMS to know that the new network element needs to be configured, the registration request comprises physical characteristics and identification information of the network element, the EMS matches the physical characteristic information reported by the network element with the physical characteristic information recorded on the EMS, if the physical characteristic information is matched with the physical characteristic information, a management channel is established between the EMS and the network element, software version information of the new network element is obtained through the management channel, and the software version of the new network element is managed through the management channel.
And determining configuration data matched with the identification information reported by the new network element according to the corresponding relation between the configuration data of the network element and the identification information recorded on the EMS, and sending the matched configuration data to the new network element through the management channel. In the scene of opening a telecommunication device, the network management system (EMS) sends the configuration data of the network element stored in the EMS to the new network element through the management channel, and when the configuration data is loaded, the EMS can automatically pack the configuration data of the network element and complete the loading at one time in order to avoid repeated resetting of the device.
After the opening of the office, the telecommunication equipment enters the operation stage of the network system, and in the network operation process, when an unrecoverable fault occurs in a certain network element in the network system, the problem is generally solved by adopting a method of updating the network element.
After the network element is replaced, an embodiment of the present invention further provides a method for managing a network element in a network system, where the method includes:
in a scenario of network element replacement, information of a network element managed by an EMS is backed up in advance in the EMS, and generally, the information of the network element includes: the corresponding relation between the backup data of the network element and the identification information, and the physical characteristic information of the network element.
S101, receiving information reported by a network element, wherein the information comprises network element physical characteristic information and identification information, and matching the physical characteristic information reported by the network element with the physical characteristic information recorded on the EMS.
In a scenario that a device in a Network fails and needs to be replaced, a Network element is an independent device in the Network, taking a PON (Passive Optical Network) system as an example, when a certain Network element in the Network, such as an ONU (Optical Network Unit), fails and needs to be replaced, a maintainer arrives at a station to replace the failed Network element, the replaced new Network element sends a registration request to an EMS system and registers to the EMS system, where the purpose of registration is to enable a Network manager to identify the replaced new Network element and match the replaced new Network element with data backed up by the replaced Network element in the Network manager to obtain backup data of the new Network element, so as to perform subsequent configuration operations. The registration request carries network element information of the new replaced network element, and the network element information includes physical characteristic information of the new replaced network element, such as a Media Access Control (MAC) address, a serial number, and the like, and identification information of the network element.
Before executing step S101, that is, when the original network element works normally, the network manager needs to backup the network element configuration data in its management range. The network element configures corresponding parameters, such as an IP address and an ethernet port rate of the network element, according to different requirements of a user during operation, and the EMS system needs to backup the configuration data of the network element within its management range in time. In actual operation, considering that the number of devices managed by the EMS system is large and the configuration data on a part of network elements does not change frequently, an identification method can be adopted to identify the network elements with changed configuration data and perform periodic backup on the identified network elements. For those network elements whose configuration data has not changed, the backup is only needed once. Meanwhile, in order to save the disk space of the EMS system, for the network element with changed configuration data, a certain data backup and storage strategy can be set in the EMS system according to the needs of specific application scenarios, for example, after the configuration data of one network element is changed for many times, the network manager does not store the past backup data of the network element, but only stores the backup data of the last times, for example, stores the data backup of the last 2 to 5 times, but generally does not store the last backup data, because if the last backup data is wrong, the previous backup data of several times can be taken as the standard, so that the backup safety can be ensured, and the purpose of saving the storage space can be achieved.
S102, matching the physical characteristic information reported by the network element with the physical characteristic information recorded on the EMS, if the physical characteristic information is not matched with the EMS, establishing a management channel with the network element, acquiring the software version information of the network element through the management channel, and managing the software version of the network element through the management channel.
After receiving the network element information reported by the network element, the EMS system matches the physical characteristic information reported by the new network element with the physical characteristics recorded on the EMS to determine whether the network element is the new network element, if the physical characteristic information reported by the new network element is not matched with the physical characteristics recorded on the EMS, the network element is considered to be a newly replaced network element, the EMS system establishes a management channel between the network manager and the replaced network element, and the process of establishing the management channel is as follows: the Network manager issues its own Management information to the Network element, so as to establish a Management channel between the Network element and the Network manager, for example, in a PON system, the Network manager issues Management information, such as an IP address of the Network manager, an SNMP (Simple Network Management Protocol, Simple Network Management Protocol parameter), and the like, to a newly replaced Network element ONU through an OLT (optical line terminal), and after the Network element receives the Management information, the establishment of the Management channel is completed, and the Network manager acquires a software version of the Network element through the Management channel to manage the software version of the replaced Network element. Since the network element is a stand-alone device in the network and includes a plurality of different components, each component may correspond to a different software release. Therefore, the software version information of the network element obtained by the network manager may be a software package information including software version information of a plurality of components. The network manager can set a certain network element software version management strategy according to the actual operation condition of the network, for example, the network element software version is upgraded to the latest version, or the original network element software version is kept unchanged, or the network element software version is downgraded to the specified version. If the original software version of the network element is selected to be kept unchanged, the current software version information of the replaced network element needs to be recorded. In a scenario that a device in a network fails and needs to be replaced, degradation is to perform degradation processing when a newly replaced network element is higher than a software version of a network element before replacement, and in a scenario that a telecommunication device opens an office, degradation is to perform degradation on a software version of a new network element when the software version of the new network element is higher than version information preset in an EMS.
S103, determining backup data matched with the reported identification information according to the corresponding relation between the backup data of the network element recorded on the EMS and the identification information.
At present, there are various ways of identifying network elements, which may be identity information based on physical characteristics of network elements, such as MAC addresses, serial numbers, etc.; the logical identity may be based on a network element, such as a Password (Password), a Key (Key), and other logical identities; or the network element may be identified based on the identification of the network element identity card, similar to the SIM card of the mobile phone.
According to different identification types, the process of matching the backup data of the network element is explained according to different conditions:
when the physical characteristic identity information of the network element is adopted to identify the network element, the replaced network element only carries the physical characteristic information of the network element in the registration request, and the network manager reads the physical characteristic information of the network element.
When the network element is identified by the logical identity, the logical identity of the network element before replacement needs to be input into the replaced network element, and the replaced network element carries the logical identity and the physical characteristics of the network element in the registration request, because the physical characteristic information of each network element is unique, the network manager can identify the replaced network element according to the physical characteristic information of the network element; meanwhile, according to the specific corresponding relation between the logic identity of the network element and the network element, when the network manager receives the logic identity of the network element, the network manager can identify which network element is replaced, and according to the corresponding relation between the backup data of the network element recorded on the EMS and the logic identity, the backup data matched with the reported logic identity is determined, and the data matching is completed. This process is automatically done by the network administrator.
When the network element is identified by the identification of the identity card, the identity card of the network element before replacement is inserted into the replaced network element, the replaced network element carries the information of the identity card and the physical characteristics of the network element in a registration request, and the network manager identifies the replaced network element according to the physical characteristic information of the network element; and meanwhile, according to the corresponding relation between the information of the identity card and the network element, the network manager identifies which network element is replaced according to the information of the identity card, and determines backup data matched with the reported identity card information according to the corresponding relation between the backup data of the network element recorded on the EMS and the information of the identity card, so as to complete data matching. This process is also done automatically by the network administrator.
S103, sending the matched backup data to a new network element through the management channel.
When equipment in the network fails and needs to be replaced, the EMS system performs network element software version matching, and then sends backup data corresponding to the replaced network element stored in the EMS system to the replaced network element through a management channel between the network manager and the network element. After receiving the above contents, the EMS system may store the configuration data of the last backup several times according to the storage policy, and the network manager only needs to restore the configuration data of the last backup to the replaced network element, and if the latest backup data is found to be incorrect, the previous or previous data can be restored to the replaced network element. According to the actual needs of users, when the software version is upgraded or downgraded, the backup data corresponding to the software version also needs to be upgraded or downgraded correspondingly to meet the needs of equipment operation, and the upgrade can be completed by a network manager or automatically completed by a network element after the replaced network element receives the backup data.
The network management system automatically configures the replaced network element, reduces the degree of manual participation, and realizes the rapid configuration of the network element, thereby improving the efficiency of network element replacement and reducing the cost of equipment maintenance of operators.
