Thanks. We'll let you know when a new response is added.

Do you have a communication link that you already have usage data for? Do you have a test environment where you can measure traffic throughput using Wireshark or something similar? Here’s a <a href=”http://www.numion.com/Calculators/Distance.html”>website</a> that may assist you in this activity.

    I want to measure Available WAN bandwidth and not throughput...I will just be telnetting to a router and need some formulae to calculate the available bandwidth. Yes, I have the communication link, just need some formulaes or some Command line interface which would say that.

    Available bandwidth = Total bandwidth - used bandwidth. This is usually measured in kilobits/sec. Are you asking for how to find used bandwidth on a router? On a Cisco router/switch you can typically type show interface xx##/## to find out how much is in use although it typically will show over a period of time of 30 seconds or 5 minutes or however the interface is configured.

    If your provider monitors your WAN link, they may (should) collect usage stats. This will permit you to show accurate usage for the link. Pull the information into Excel and do statistical analysis such as frequency distribution to see how busy the link is during working hours vs weekend hours.
