OSI Model & Network Management: How network management relates to the OSI model layers (especially Layers 1-4). Network Management System (NMS): Tools and platforms used to monitor and manage network resources. 1. Network Management Frameworks SNMP (Simple Network Management Protocol): Protocol used to collect and organize information about managed devices on IP networks. Components of SNMP: Manager Agent Management Information Base (MIB) Versions: SNMPv1, SNMPv2c, SNMPv3 RMON (Remote Monitoring): Used for monitoring network devices, often integrated with SNMP. 2. Network Topology and Design Topological Management: Involves designing the network layout (e.g., bus, star, mesh). Performance Metrics: Throughput, latency, error rates, etc. 3. Network Fault Management Fault Detection: Techniques for detecting network failures (e.g., ICMP pings, monitoring alerts). Troubleshooting Tools: Ping, traceroute, telnet, etc. Root Cause Analysis: Identifying the source of network issues. 4. Network Configuration Management Configuration Management Tools: Automation tools for managing device settings (e.g., Ansible, Chef, Puppet). Device Configuration: Modifying and updating router, switch, and server configurations. 5. Network Performance Management Performance Monitoring: Tools and protocols for measuring network performance (e.g., NetFlow, Wireshark, iPerf). Traffic Analysis: Understanding traffic flow, bottlenecks, and optimizing network usage. Quality of Service (QoS): Prioritizing traffic to ensure critical services perform well. 6. Network Security Management Access Control: Managing who can access the network and ensuring only authorized users are allowed. Firewall Management: Configuring and monitoring firewalls. Intrusion Detection Systems (IDS): Monitoring traffic for suspicious activity. 7. Bandwidth and Traffic Management Bandwidth Utilization: Techniques for monitoring and optimizing bandwidth. Traffic Shaping and Policing: Managing network traffic to prevent congestion and ensure fair usage. 8. Backup and Disaster Recovery Network Data Backup: Ensuring regular backup of network configurations and critical data. Disaster Recovery Plans: Steps to recover from major network failures, including data restoration and failover systems. 9. Network Documentation Network Diagrams: Visual representations of network structures. Configuration and Change Logs: Keeping records of network settings and changes made to devices. Emerging Technologies Q/ What are Emerging Technologies to Manage Networks recently? Answer: SDN (Software-Defined Networking): A newer approach where network control is separated from hardware. Network Automation: Automating network tasks and configurations using scripting and software tools. 5G Networks: Managing next-gen networks with higher bandwidth and lower latency.
