ROI calculator for Bandwidth Controllers


Is your commercial Internet link getting full ? Are you evaluating whether to increase the size of your existing internet pipe and trying to do a cost trade off on investing in an optimization solution? If you answered yes to either of these questions then you’ll find the rest of this post useful.

To get started, we assume you are somewhat familiar with the NetEqualizer’s automated fairness and behavior based shaping.

To learn more about NetEqualizer behavior based shaping  we suggest our  NetEqualizer FAQ.

Below are the criteria we used for our cost analysis.

1) It was based on feedback from numerous customers (different verticals) over the previous six years.

2) In keeping with our policies we used average and not best case scenarios of savings.
3) Our Scenario is applicable to any private business or public operator that administers a shared Internet Link with 50 or more users

4) For our example  we will assume a 10 megabit trunk at a cost of $1500 per month.

ROI savings #1 Extending the number of users you can support.

NetEqualizer Equalizing and fairness typically extends the number of users that can share a trunk by making better use of the available bandwidth in a time period. Bandwidth can be stretched from 10 to 30 percent:

savings $150 to $450 per month

ROI savings #2 Reducing support calls caused by peak period brownouts.

We conservatively assume a brownout once a month caused by general network overload. With a transient brownout scenario you will likely spend debug time  trying to find the root cause. For example, a bad DNS server could the problem, or your upstream provider may have an issue. A brownout  may be caused by simple congestion .   Assuming you dispatch staff time to trouble shoot a congestion problem once a month and at an overhead  from 1 to 3 hours. Savings would be $300 per month in staff hours.

ROI savings #3 No recurring costs with your NetEqualizer.

Since the NetEqualizer uses behavior based shaping your license is essentially good for the life of the unit. Layer 7 based protocol shapers must be updated at least once a year.  Savings $100 to $500 per month

The total

The cost of a NetEqualizer unit for a 10 meg circuit runs around $3000, the low estimate for savings per month is around $500 per month.

In our scenario the ROI is very conservatively 6 months.

Note: Commercial Internet links supported by NetEqualizer include T1,E1,DS3,OC3,T3, Fiber, 1 gig and more
