The True Price of Bandwidth Monitoring

For most IT administrators, bandwidth monitoring of some sort is an essential part of keeping track of, as well as justifying, network expenses. Without visibility into a network load, an administrator’s job would degrade into a quagmire of random guesswork. Or would it?

The traditional way of  looking at monitoring your Internet has two parts: the fixed cost of the monitoring tool used to identify traffic, and the labor associated with devising a remedy. In an ironic inverse correlation, we assert that costs increase with the complexity of the monitoring tool. Obviously, the more detailed the reporting tool, the more expensive its initial price tag. The kicker comes with part two. The more expensive the tool, the more  detail  it will provide, and the more time an administrator is likely to spend adjusting and mucking, looking for optimal performance.

But, is it a fair to assume higher labor costs with  more advanced monitoring and information?

Well, obviously it would not make sense to pay more for an advanced tool if there was no intention of doing anything with the detailed information it provides. Why have the reporting tool in the first place if the only output was to stare at reports and do nothing? Typically, the more information an admin has about a network, the more inclined he might be to spend time making adjustments.

On a similar note, an oversight often made with labor costs is the belief  that when  the work needed to adjust the network comes to fruition, the associated adjustments can remain statically in place. However, in reality, network traffic changes constantly, and thus the tuning so meticulously performed on Monday may be obsolete by Friday.

Does this mean that the overall productivity of using a bandwidth tool is a loss? Not at all. Bandwidth monitoring and network mucking can certainly result in a cost-effective solution. But, where is the tipping point? When does a monitoring solution create more costs than it saves?

A review of recent history reveals that technologies with a path similar to bandwidth monitoring have become commodities and shunned the overhead of most human intervention.  For example, computer operators disappeared off the face of the earth with the invention of cheaper computing in the late 1980’s.  The function of a computer operator did not disappear completely, it just got automated and rolled into the computer itself. The point is, anytime the cost of a resource is falling, the attention and costs used to manage it should be revisited.

An effective compromise with many of our customers is that they are stepping down from expensive complex reporting tools to a simpler approach. Instead of trying to determine every type of traffic on a network by type, time of day, etc., an admin can spot trouble by simply checking overall usage numbers once a week or so. With a basic bandwidth control solution in place (such as a NetEqualizer), the acute problems of a network locking up will go away, leaving what we would call only “chronic” problems, which may need to be addressed eventually, but do not require immediate action.

For example, with a simple reporting tool you can plot network usage by user.  Such a report, although limited in detail, will often reveal a very distinct bell curve of usage behavior. Most users will be near the mean, and then there are perhaps one or two percent of users that will be well above the mean. You don’t need a fancy tool to see what they are doing; abuse becomes obvious just looking at the usage (a simple report).

However, there is also the personal control factor, which often does not follow clear lines of ROI (return on investment).

What we have experienced when proposing a more hands-off model to network management is that a customer’s comfort depends on their bias for needing to know, which is an unquantifiable personal preference. Even in a world where bandwidth is free, it is still human nature to want to know specifically what bandwidth is being used for, with detailed information regarding the type of traffic. There is nothing wrong with this desire, but we wonder how strong it might be if the savings obtained from using simpler monitoring tools were converted into a trip to Hawaii.

In our next article, we’ll put some real world numbers to the test for actual break downs, so stay tuned. In the mean time, here are some other articles on bandwidth monitoring that we recommend. And, don’t forget to take our poll.

Where are the safe tech jobs ?

Article Type: Opinion

As the CEO of a small (yet growing) tech company in the current recession I often get calls from former colleagues working at larger corporations. Amidst their companies insincere rhetoric, inaction, and falling revenues, good people wait around wondering who will be next to get the ax.

The underlying problem at most of these companies is that they are continue to push products into a stagnant or declining market. The only way to have any relative security is to get on board with an industry or niche with solid growth potential.

So if your wondering where to turn for potential job security here are some tips that might help

Look for a company that is doing something with real value for society and not just jumping on the latest bandwagon.

1) Renewable energy is hot , and certainly a job in renewable energy is better than selling steam engines running off coal. Renewable energy, although here to stay is being over hyped . Right now the success of renewable energy is dependent on battery technology. Fossil fuels are nothing more than the Suns energy stored up and retrieved at will when needed. For renewable (wind, solar) energy is to compete easily with traditional fossil fuels we must come up with a clean effective battery to store energy. My advice seek out a company that specializes in battery technology and then help them make a difference.

2) Network and Internet Optimization

Internet Infrastructure companies are being forced by their stock holders to turn a profit. The days of free falling bandwidth contracts are slowing down, hence the new hot market will be companies with products that optimize internet bandwidth. Bandwidth control , WAN optimization and compression although not on the front pages, are areas of value and are holding their own in the recession. Some companies to look at , are

APconnection (NetEqualizer)

Packeteer

Allot

RiverBed

Exinda

3) Medical Technology,

From newer and better and MRI machines to prosthetics , Americans will spare no expense for anything that will make their lives more comfortable. So when will this party end and the associated demand for jobs in the Medical Industry flatten out?

Although I do not expect a crash in this field as we might have seen in other boom and bust industries, I do expect a slowdown. Every bubble has its end, and the Medical technology industry is due for a slow down. As consumers push back on medical care pricing, high end technology research will slow down. Still a better prospect than steam engines though.

4) Auto Industry

If you are entering into the field of Mechanical Engineering or electronics controls now would be a good time to focus on the Auto Industry. For the next 5 to 10 years I expect that auto makers will be looking for new innovative ideas in their engineering departments. They will also be looking for new talent. Don’t let the down turn discourage you this is an opportunity.

Tired of Being Asked Why the Internet Is So Slow?


We recently received this update from NetEqualizer user Chris Gilles of the Heartwood Institute. We’ve posted it with his permission…

“I’ve had my neteq in about 2 weeks now. It’s running great!. I really never want to hear, ‘Why is the internet so slow?’ ever again. I used to hear it at least 20 times a day. Now, I hear it never. Thanks guys. Of course, I only hear, ‘Wow, the internet is so fast’ about twice a day, but it will do. Still, after months of being harassed, it’s nice not to have that ‘stress’ of hearing it all day.”
