What Are the Different Network Management Models?

The network management framework is the basic structure of various network management applications and is the de facto standard for computer network management. The network management framework describes the management issues of the system in a high-level manner, establishes a model for all management standards, gives guidelines, and specifies an open system network management model. ^[1]

(1) The management function is divided into two parts: management station and agent;

(2) Provide database support for storage management information;

(3) Provide user interface and user view functions;

(4) Provide basic management operations.

Network Management Framework Network Management

There is no precise definition of network management. Its content can be summarized as follows: network management includes the use, integration, and coordination of hardware, software, and human resources in order to monitor, test, configure, analyze, evaluate, and control network resources. Reasonable prices meet some network requirements, such as real-time operation performance and service quality.

Network management is often referred to as network management. Network management does not refer to the administrative management of the network. The network is a very complex distributed system. This is a node produced by many different manufacturers on the network and running multiple protocols (mainly routers), and these nodes are still communicating and exchanging information with each other.

There is a basic principle of network management: if you want to manage an object, you must add some software or hardware to the object, but this addition must have a small impact on the original object. ^[3]

Network Management Framework Network Management Model

The network management model defines the framework, methods, and methods of network management. Different management models will bring different management capabilities, management efficiency and economic benefits, and determine different complexity, flexibility and compatibility of network management systems. In the late 1980s, the remote monitoring-based management framework proposed by ISO was the basis of the modern network management model. On this basis, a proposal for establishing an Integrated Network Management System (INMS) was proposed, and two main network management models, namely, a system management model based on the OSI model (Public Management Information Protocol, Common Management Information Protocol (CMIP) and Network Management Model (SNMP) based on TCP / IP model. ^[4]

Network Management Framework Simple Network Management Protocol

The Simple Network Manager Protocol (SNMP) provides a network management framework for the network management system. The SNMP protocol has a wide range of applications and can be used in many types of network equipment, software and systems.

The most important guiding idea of SNMP is to be as simple as possible. The basic functions of SNMP include monitoring network performance, detecting and analyzing network errors, and configuring network devices. When the network is working normally, SNMP can implement statistics, configuration, and testing functions. When the network fails. Can realize various error detection and recovery functions. Only authorized personnel are qualified to perform network management functions (such as closing a link) and read information about network management (such as reading the contents of a configuration file).

However, the SNMP protocol is quite large. It's not "easy" at all, and there are eight RFC documents for the entire standard.

The network management of SNMP is composed of three parts, namely SNMP itself, SMI (Structure of Management Information) and MIB (Management Information Base). ^[3]
