Study Notes
Network Management
- Network management entails tools for monitoring, testing, configuring, analyzing, evaluating, and controlling network operations.
- Key components of a network management architecture include: a network manager, managed remote devices, management information bases (MIBs), remote agents (reporting and acting per manager's instructions), and a protocol for communication.
- Internet Network Management Framework and SNMP protocol are detailed components of network management.
- ASN.1 is a structured way to define data types used in network management.
- The network administrator's job is to maintain network functionality and operation.
- Network malfunctions (cable cuts, device failures) frequently occur and must be addressed by the network administrator.
- Monitoring, managing, and controlling large networks requires appropriate tools.
Network Management Scenarios
- Real-world examples like control rooms monitoring power plant components or airplane cockpits illustrate the importance of monitoring, management, and control within complex systems.
- Administrators in these contexts react to problems and proactively manage the system's performance.
Network Management Tools
- Network management tools are critical in identifying and resolving network issues, especially within large, distributed networks.
- Tools enable proactive problem identification (like failing interfaces) before issues affect users.
- Tools allow monitoring of network traffic for potential problems.
- Tools assist in managing large networks, enabling administrators to react quickly to changing conditions.
Network Management Components
- Managing entities—in charge of the overall network state—reside in a central location, often a Network Operations Center (NOC).
- A managed device is any piece of network hardware in use.
- A network management agent runs on or within a managed device.
- The agent helps communicate with the managing entity and complete local management tasks.
- A network management protocol acts as the communication channel between the managing entity and the managed devices.
Key Network Management Protocols
- Simple Network Management Protocol (SNMP) is frequently used for collecting and organizing information about managed devices and to alter their behavior on an IP network. Key parts/components of SNMP include managed devices, agents and network management systems (NMSs).
Network Management Information
- Understanding network configuration details (processor type, size of hard drive, and RAM) is crucial for management.
- Administrators use network management software for a detailed view of hardware and software, and to manage resources.
- Management Information Bases (MIBs) hold information about the managed devices in a network, describing how to manage them.
- The managing entity uses data from monitoring systems and from managed devices to diagnose and resolve network issues.
Key Considerations In Network Design
- It is important to plan before implementing a network.
- Pre-emptive planning will be crucial in identifying/mitigating potential issues.
- Purpose and scope of the network need clarification before any implementation begins.
- Use of a dedicated server is important for complex or significant needs, rather than a peer-to-peer model.
- The choice of a dedicated server needs to be suitable to the network's needs.
- There are many types of servers that can be used, for example file servers, print servers, web servers, and mail servers.
