Lisa Bock covers the importance of baselining the network, as there are many benefits to this, such as capacity planning, security management, and quality of service analysis. She also reviews the four stages, including plan, capture, analyze, and save.
- [Instructor] On any enterprise network,…data flows through a variety of devices.…Each device can influence the nature of the traffic.…Periodically monitoring traffic is essential…to detect problems before they occur.…An important exercise for the network administrator…is to conduct a network baseline.…Baselining the networks have many benefits,…such as capacity planning, security management,…and quality of service analysis.…
I think the most important part of baselining is,…once you learn what normal behavior looks like,…you'll be able to better identify…abnormal network behavior, and you'll be able to…troubleshoot problems that may occur in the future.…A baseline is a snapshot of network traffic during…a particular window of time using Wireshark or TShark.…Characteristics can include utilization,…network protocols, and latency issues.…
The network team can then use the baselines for forecasting,…planning, optimization, tuning, and troubleshooting.…The baselining process goes through several stages,…plan, capture, analyze, and save.…
