Enjoy another issue of NetEqualizer News! This month, we preview feature additions to NetEqualizer coming in 2013, offer a special deal on web application security testing for the Holidays, and remind NetEqualizer customers to upgrade to Software Update 6.0. As always, feel free to pass this along to others who might be interested in NetEqualizer News.
A message from Art…
Art Reisman, CTO – APconnections
This month’s picture is from Parent’s Night for my daughter’s volleyball team. In December, as I get ready for the Holidays, I often think about what is important to me – like family, friends, my health, and how I help to run this business. While pondering these thoughts, I came up with some quotes that have meaning to me, which I am sharing here. I hope you enjoy them, or that they at least get you thinking about what is important to you!
“Technology is not what has already been done.”
What are your favorite quotes? We love it when we hear back from you – so if you have a quote or a story you would like to share with us of how we have helped you, let us know. Email me directly at email@example.com. I would love to hear from you!
We are always looking to improve our NetEqualizer product line such that our customers are getting maximum value from their purchase. Part of this process is brainstorming changes and additional features to adapt and help meet that need.
Here are a couple of ideas for changes to NetEqualizer that will arrive in 2013. Stay tuned to NetEqualizer News and our blog for updates on these features!
1) NetEqualizer in Mesh Networks and Cloud Computing
As the use of NAT distributed across mesh networks becomes more widespread, and the bundling of services across cloud computing becomes more prevalent, our stream-based behavior shaping will need to evolve.
This is due to the fact that we base our decision of whether or not to shape on a pair of IP addresses talking to each other without considering port numbers. Sometimes, in cloud or mesh networks, services are trunked across a tunnel using the same IP address. As they cross the trunk, the streams are broken out appropriately based on port number.
So, for example, say you have a video server as part of a cloud computing environment. Without any NAT, on a wide-open network, we would be able to give that video server priority simply by knowing its IP address. However, in a meshed network, the IP connection might be the same as other streams, and we’d have no way to differentiate it. It turns out, though, that services within a tunnel may share IP addresses, but the differentiating factor will be the port number.
Thus, in 2013 we will no longer shape just on IP to IP, but will evolve to offer shaping on IP(Port) to IP(Port). The result will be quality of service improvements even in heavily NAT’d environments.
2) 10 Gbps Line Speeds without Degradation
Some of our advantages over the years have been our price point, the techniques we use on standard hardware, and the line speeds we can maintain.
Right now, our NE3000 and above products all have true multi-core processors, and we want to take advantage of that to enhance our packet analysis. While our analysis is very quick and efficient today (sustained speeds of 1 Gbps up and down), in very high-speed networks, multi-core processing will amp up our throughput even more. In order to get to 10 Gbps on our Intel-based architecture, we must do some parallel analysis on IP packets in the Linux kernel.
The good news is that we’ve already developed this technology in our NetGladiator product (check out this blog article here).
Coming in 2013, we’ll port this technology to NetEqualizer. The result will be low-cost bandwidth shapers that can handle extremely high line speeds without degradation. This is important because in a world where bandwidth keeps getting cheaper, the only reason to invest in an optimizer is if it makes good business sense.
We have prided ourselves on smart, efficient, optimization techniques for years – and we will continue to do that for our customers!
Secure Your Web Applications for the Holidays!
We want YOU to be proactive about security. If your business has external-facing web applications, don’t wait for an attack to happen – protect yourself now! It only takes a few hours of our in-house security experts’ time to determine if your site might have issues, so, for the Holidays, we are offering a $500 upfront security assessment for customers with web applications that need testing!
If it is determined that our NetGladiator product can help shore up your issues, that $500 will be applied toward your first year of NetGladiator Software & Support (GSS). We also offer further consulting based on that assessment on an as-needed basis.

Don’t Forget to Upgrade to 6.0!: With a brief tutorial on User Quotas
If you have not already upgraded your NetEqualizer to Software Update 6.0, now is the perfect time!
We have discussed the new upgrade in depth in previous newsletters and blog posts, so this month we thought we’d show you how to take advantage of one of the new features – User Quotas.
User quotas are great if you need to track bandwidth usage over time per IP address or subnet. You can also send alerts to notify you if a quota has been surpassed.
To begin, you’ll want to navigate to the Manage User Quotas menu on the left. You’ll then want to start the Quota System using the third interface from the top, Start/Stop Quota System.
Now that the Quota System is turned on, we’ll add a new quota. Click on Configure User Quotas and take a look at the first window:
Here are the settings associated with setting up a new quota rule:
Host IP: Enter in the Host IP or Subnet that you want to give a quota rule to.
Quota Amount: Enter in the number of total bytes for this quota to allow.
Duration: Enter in the number of minutes you want the quota to be tracked for before it is reset (1 day, 1 week, etc.).
Hard Limit Restriction: Enter in the number of bytes/sec to allow the user once the quota is surpassed.
Contact: Enter in a contact email for the person to notify when the quota is passed.
After you populate the form, click Add Rule. Congratulations! You’ve just set up your first quota rule!
From here, you can view reports on your quota users and more.
Remember, the new GUI and all the new features of Software Update 6.0 are available for free to customers with valid NetEqualizer Software & Support (NSS).
If you don’t have the new GUI or are not current with NSS, contact us today!

Internet User’s Bill of Rights
By Art Reisman – CTO – APconnections
This is the second article in our series. Our first was a Bill of Rights dictating the etiquette of software updates. We continue with a proposed Bill of Rights for consumers with respect to their Internet service.
1) Providers must divulge the contention ratio of their service.
At the core of all Internet service is a balancing act between the number of people that are sharing a resource and how much of that resource is available.
For example, a typical provider starts out with a big pipe of Internet access that is shared via exchange points with other large providers. They then subdivide this access out to their customers in ever smaller chunks – perhaps starting with a gigabit exchange point and then narrowing down to a 10 megabit local pipe that is shared with customers across a subdivision or area of town.
The speed you, the customer, can attain is limited to how many people might be sharing that 10 megabit local pipe at any one time. If you are promised one megabit service, it is likely that your provider would have you share your trunk with more than 10 subscribers and take advantage of the natural usage behavior, which assumes that not all users are active at one time.
The exact contention ratio will vary widely from area to area, but from experience, your provider will want to maximize the number of subscribers who can share the pipe, while minimizing service complaints due to a slow network. In some cases, I have seen as many as 1,000 subscribers sharing 10 megabits. This is a bit extreme, but even with a ratio as high as this, subscribers will average much faster speeds when compared to dial up…

The wide-open ranch lands in middle America provide a nice retreat from the bustle of city life. When he can find time, one of our staff members visits his property in Kansas with his family. The Internet connection out there is shaky, but it is a welcome change from routine.
