Disbelief is a common theme in our demo process with potential customers. When we use our AppNeta Performance Manager to show a customer their own data for a particular office, they almost immediately ask why the capacity metrics are low. If the customer is paying for 250 Mbps out of that office, why is AppNeta only showing them 46 Mbps?...

In a World of Mobile and BYOD, Is QoS Enforcement Possible?
by Joe Michalowski on

There was a time when the consumerization of IT struck fear in the hearts of any network manager. It was easier to push back and deny or ignore iPhones in the workplace than to actually revamp the network to support them—not to mention prepare for the onslaught of cyber threats that came along with them. But that was years ago....

Don't Hog the Bandwidth, and Other Network Tips
by Christine Cignoli on

What’s your bandwidth-consuming vice these days? Maybe March Madness? You’re certainly not alone. Even employees in the very important Pentagon are hooked. The Pentagon’s ISP asked employees to reconsider streaming basketball games in light of the important work their bandwidth is supporting—defending the country and all that. We’re sure they have excellent network monitoring helping the effort to pin down...

This past summer, I wrote about T1s and three best practices for WAN Performance. As I mentioned in that post, T1-class WAN services are a popular way to connect branch offices to corporate data centers and the Internet for voice and other application services. While the 1.54Mbps definition of a T1 hasn’t changed over time, it’s now common to see multiple T1...
