In working with numerous Business Center network administrators, we have heard the same issues and challenges repeatedly. Here are just a few:
- We need to do more with less bandwidth.
- We need a solution that’s low cost, low maintenance, and easy to set up.
- We need to support selling fixed bandwidth to our customers, by office and/or user.
- We need to be able to report on subscriber usage.
- We need to increase user satisfaction and reduce network troubleshooting calls
In this article, we’ll talk about how the NetEqualizer has been used to solve these issues for many Business Centers around the world.

We need to do more with less bandwidth.
NetEqualizer’s built-in rules-based, application-level traffic-shaping technology dynamically controls traffic based on current network usage. When the network is congested, the “fairness” algorithm favors business-class applications, including VoIP, Web browsing, chat and email, at the expense of larger file downloads. This approach allows network managers and operators to maintain high levels of user satisfaction without having to purchase additional bandwidth.
Our Business Center clients find that they are able to have higher subscriber ratios, supporting more subscribers on existing bandwidth, when using the NetEqualizer. This enables them to stretch bandwidth further, making their existing capital investment more cost-effective, and we can help you do the same.
We need a solution that’s low cost, low maintenance, and easy to set up.
Put simply, the NetEqualizer is a “plug-and-play” solution. Once you put the NetEqualizer in place, it immediately and effectively handles traffic shaping automatically around the clock. You simply need to define the size of your network pipe, establish the level of total bandwidth usage (default is 85%) at which you want shaping to kick in, make sure that the defaults are “on,” and that’s it.
In general, the NetEqualizer is installed between your Router and your Switch, acting as a transparent bridge once in place. It will reside passively in your network until bandwidth shaping is needed, and when the set level of congestion is reached, it kicks in to smooth your network traffic.
There are additional parameters that you can set to customize your NetEqualizer implementation. However, many of our customers find that they do not need to make any changes to the default settings in order for their network performance to improve dramatically.
We need to support selling fixed bandwidth to our customers, by office and/or user.
With the NetEqualizer, administrators will find they have significantly greater control over how bandwidth is distributed through the ability to shape their network traffic by IP address, MAC address, VLAN or subnet.
The NetEqualizer provides the ability to set “hard limits” for both inbound and outbound traffic by individual ip address, to support setting fixed bandwidth per customer. In addition, you can set hard limits for a class of ip addresses (B or C), if you have a contiguous block of ip addresses that you want to limit. Alternatively, hard limits can be set up VLAN or MAC address as well. For more information on each shaping strategy, see our detailed NetEqualizer User Guide.
We need to be able to report on subscriber usage.
Once you have your fixed bandwidth allocated, you can use NetEqualizer’s reporting capabilities to see how much network utilization is being used in real-time by each subscriber (ip address) on your network. This will help you to track and report on network usage, so that you can send notification letters to your customers on their bandwidth utilization. For customers consistently hitting their fixed allocation maximum, this could include a recommendation to increase their bandwidth allocation to correct the issue.
We need to increase user satisfaction and reduce network trouble-shooting calls.
The NetEqualizer concept of “fairness” enables your network to continue providing quick response times to the majority of your users while restricting the network hogs. Low bandwidth users do not have to share the pain of a slow, congested network with the network-hogging applications. Your guests expect email and web surfing to be responsive, and with bandwidth shaping, they will be.
For example, suppose your network is being used as follows:
• 95 percent of users are surfing the Web
– Of these, 20 percent are also on Skype call
– Another 30 percent are also watching YouTube and running chat sessions
• 5 percent are watching YouTube
• 10 percent are participating in a WebEx or GoToMeeting online meeting
In this example, if your trunk is saturated, the NetEqualizer would add latency to the YouTube streams (since they are the most bandwidth intensive), leaving all the other streams alone. So instead of having your network crash completely, a few YouTube videos would break up for a few seconds, and then when conditions abated, they would be allowed to run.
The exact allocations per user are not changed here. We maintain each customer’s fixed bandwidth allocation, and put delays on the nastiest “hog” traffic until the bandwidth usage overall drops back to 85 percent (or the setting you choose). This quickly takes the delay away until your network is no longer congested. The value is that you get the best possible usage of your network bandwidth without having to micro-manage your network.

However, if videoconferencing is an integral part of your customer’s usage at your Business Center, NetEqualizer enables you to treat the videoconferencing host as high priority, through our “priority hosts” feature. This will cause the videoconferencing host not to be shaped, and to always be given priority over other traffic. Priority hosts can be set-up permanently or temporarily in the NetEqualizer.
For organizations concerned with achieving maximum network uptime, the NetEqualizer architecture enables customers to build a redundant configuration by putting a second NetEqualizer in place as either a cold backup or in hot swappable mode.
