Shulou(Shulou.com)06/01 Report--

As of March 2020, the number of Chinese Internet users was 904 million, an increase of 75.08 million over the end of 2018, and the Internet penetration rate reached 64.5%. The number of mobile Internet users reached 897 million, and the proportion of Internet users using mobile phones to surf the Internet reached 99.3%. It can be said that people's life is more and more dependent on the network, especially affected by the epidemic, many offline businesses are also transformed into network operation, the quality of network services directly affects the stability of enterprise business.

The stability of network services depends on the effective maintenance and management of network infrastructure. At present, many companies are maintaining the IT network manually, which greatly consumes the working time of operation and maintenance. How to reject inefficient, intelligent and network management platform SugarNMS Netconf tools can provide for the operation and maintenance of what capabilities, let's take a look.

What can Netconf tools do?

Take the configuration of the operator router as an example, you need to view the documentation on the manufacturer's official website, learn the product documentation, and then enter commands on the switch to manually operate these commands for configuration. However, if there are polymorphic routers in different buildings or in different areas, it will be very troublesome, and the work will be repeated, affecting the efficiency of operation and maintenance. Netconf tools are used to configure multiple devices in batches at one time to realize intelligent and efficient operation and maintenance.

Netconf protocol provides a mechanism for managing network devices, and users can add, modify and delete the configuration of network devices, as well as obtain the configuration and status information of network devices. Through the NETCONF protocol, network devices can provide a set of fully standardized API; applications can directly use these API to send and obtain configurations to network devices.

In addition to configuration data, the device also stores status data and information, such as packet statistics and other data collected by running devices. Zhihe network management platform can read these data through Netconf tools for big data processing and analysis.

The candidate configuration data store is an optional device performance. If enabled, it contains a set of configuration data that the controller can use to update running data stores and modify device operations. Separating the running configuration data from the alternate configuration data can eliminate the problem of configuration differences, while a series of CLI commands are updating the configuration, and as one command after another is executed, the configuration will be in an inconsistent state.

The Netconf protocol defines multiple data stores, or sets of configuration data. The running configuration data store contains configuration information that the current device is using. Some devices also store startup configuration data, which contains the configuration data when the device starts for the first time, which is separated from the running configuration data.

Advantages of Netconf tools

Netconf protocol is divided into four layers: content layer, operation layer, RPC layer, communication protocol layer. Each layer wraps an aspect of the protocol and provides related services to the upper layer. The hierarchical structure can make each layer pay attention to only one aspect of the protocol and make it easier to implement. at the same time, it can decouple the dependence between each layer reasonably, and minimize the impact of the changes in the internal implementation mechanism of each layer on other layers.

Summarizing the security defects of SNMPV1,V2 is not difficult to find, because it uses connectionless UDP transport protocol, which is different from SNMP using connectionless UDP as transport protocol. Netconf is connection-oriented, it requires a permanent connection between communication ports, and such a connection must provide reliable, sequential data transmission. In the transport layer, Netconf worked out the implementation schemes of mapping to the transport protocols SSH, SOAP and BEEP respectively by RFC4742, RFC4743 and RFC4744. These security protocols ensure the security of network connections by means of encryption and authentication.

Protocol toolset

The SugarNMS protocol toolset of Zhihe network management platform includes Netconf tools, IPMI tools, SQL tools, Ping tools, GRPC tools, JMX tools, shell tools, snmp tools and so on. Device diagnostics supports multi-protocol and multi-thread collection, and supports Netconf, SNMP, telnet, ICMP, Ping, SSH, JMX, GRPC, IPMI, jdbc, odbc, onvif management protocols, etc., and can realize the network management and control requirements of computers, network devices, servers, switches, routers, video surveillance devices, intelligent terminals, security devices, cloud devices, software services and other underlying things.

The platform supports stable operation on domestic equipment, and can intelligently monitor and manage domestic equipment and systems, support domestic platform, and also support Windows and Linux platforms. It is a solution that can realize 100% integrated management of domestic network, equipment and software.

Secondary development of operation and maintenance monitoring platform

Zhihe network management platform SugarNMS empowers the secondary development capability of enterprise operation and maintenance monitoring platform. It is a secondary development platform of network management software with highly telecom-level architecture, modularization, componentization and multi-tier distributed design. It provides network management basic components, development framework, development API, development library, development plug-ins, development source code, development documents and other development materials, providing users with intelligent network management functions and personalized development capabilities. With database development, API development, server plug-in development, client development, open code development, integrated development and other models. Through a week of development training, you can get started and solve 80% of the development problems. It is used in more than 30 provinces across the country, covering national defense, scientific research institutes, government, finance, transportation, energy, telecommunications, institutions, enterprises, education, medical care and other fields.
