Question: According to the ISO definition of network management functions, what are the main aspects included?

Answer:

According to the International Organization for Standardization (ISO), specifically within the ISO/IEC 7498-4 standard (which is part of the Open Systems Interconnection or OSI model framework), network management is defined by five functional areas. These are commonly referred to as the FCAPS model.

The five main aspects are:

  1. Fault Management (故障管理)
    • Purpose: To detect, log, notify users of, and (to the extent possible) automatically fix network problems to keep the network running effectively.
    • Key Activities: Error detection, isolation, correction, and maintaining an error log. It often involves monitoring for alarms and ensuring high availability.
  2. Configuration Management (配置管理)
    • Purpose: To monitor and manage the configuration of network devices and software to maintain a desired state.
    • Key Activities: Identifying managed objects, initializing the network, setting parameters, collecting configuration data, and modifying configurations (e.g., adding new devices or updating firmware).
  3. Accounting Management (计费管理)
    • Purpose: To track network usage by individuals or groups so that usage fees can be determined and billed appropriately. It also helps in managing resource quotas.
    • Key Activities: Measuring network utilization, establishing billing rates, generating invoices, and enforcing usage limits. In non-billing environments, this is sometimes referred to as “Administration” or “Usage Management.”
  4. Performance Management (性能管理)
    • Purpose: To measure and make available various aspects of network performance to ensure the network runs efficiently.
    • Key Activities: Gathering statistical data (such as throughput, latency, packet loss, and utilization), analyzing trends, and tuning network parameters to optimize performance.
  5. Security Management (安全管理)
    • Purpose: To control access to network resources according to local guidelines so that the network cannot be sabotaged (intentionally or unintentionally) and sensitive information cannot be accessed by unauthorized users.
    • Key Activities: Authentication, authorization, encryption key management, security logging, and detecting security breaches (such as virus infections or intrusion attempts).

Summary Mnemonic: These five functions are often remembered by the acronym FCAPS:
