a) The performance of a local area computer network is crucial for the overall functioning of an organization or business. Mentioning the performance of the network is important for several reasons:
1) Identifying bottlenecks: By monitoring the performance of the network, IT professionals can identify any bottlenecks or limitations that may be impacting the overall productivity of the organization. This allows them to address these issues proactively and prevent any disruptions to workflow.
2) Capacity planning: Understanding the performance of the network helps in capacity planning, which involves estimating future network needs and ensuring that the network can handle the expected growth in traffic and data usage.
3) Troubleshooting: When performance issues arise, having data on the network's performance can help IT professionals troubleshoot and diagnose the root cause of the problem more effectively. This can lead to quicker resolution and minimize downtime.
4) Security: Monitoring network performance can also help in detecting any suspicious activity or security breaches that may be affecting the network. This allows for immediate action to be taken to protect sensitive data and prevent further damage.
b) Techniques used to collect network performance data include:
1) Network monitoring tools: There are a variety of network monitoring tools available that can track and analyze network performance metrics such as bandwidth usage, latency, packet loss, and network congestion. These tools provide real-time data on the network's performance and generate reports for analysis.
2) SNMP (Simple Network Management Protocol): SNMP is a protocol used to monitor and manage network devices. It allows for the collection and analysis of performance data from routers, switches, and other network equipment.
3) Packet sniffing: Packet sniffing involves capturing and analyzing the packets of data that are sent across the network. This technique can provide detailed insights into network traffic, performance issues, and potential security threats.
4) Flow analysis: Flow analysis tools track the flow of data packets across the network and provide information on bandwidth usage, network traffic patterns, and application performance.
5) Performance testing: Conducting performance tests on the network using tools like Iperf or Ping can help measure network performance under different conditions and identify areas that may need improvement.
