3.1 Briefly explain usinge appropriate statistics and sensors to ensure network availability.
Ensuring network availability involves monitoring the network to identify and resolve issues that may affect its performance. This can be done by using various statistics and sensors, such as:
1. Network utilization statistics: These statistics show the amount of data being transmitted and received on the network and can help identify bottlenecks and hot spots.
2. Latency and jitter sensors: Latency is the time it takes for data to travel from one point to another, and jitter is the variation in the latency over time. High latency or jitter can affect the quality of real-time applications, such as voice or video calls.
3. Packet loss sensors: Packet loss occurs when data is not successfully transmitted and received, resulting in a loss of information. Packet loss sensors can help identify issues that may be causing this, such as network congestion or malfunctioning devices.
4. Error sensors: Error sensors can detect issues with the network's physical layer, such as cable problems or faulty network devices.
By monitoring these statistics and sensors, network administrators can proactively identify and resolve potential issues that may affect network availability, ensuring that the network is up and running smoothly and that users have access to the resources they need.
