Cisco Performance Routing isn’t your grandfather’s routing. Cisco Performance routing (PfR for short) considers a particular path’s traffic characteristics when determining the best path for the conversation. Imagine being able to use actual delay, packet loss, MOS, jitter and more to give your router a better idea of the traffic conditions. With that data it can make a smart decision on how to route the conversation traffic. Add to that the ability to report on this with something simple like Netflow and you have solution that sounds to good to be true. Well, it isn’t!

It’s no secret the BYOD (Bring Your Own Device) revolution is in full swing, and you need to know how to monitor iPAD HD traffic on your corporate network. Long gone are the days where network administrators can police employees based solely on their desktop computer traffic. Cubicles are filled with 4 generations of iPhones, a variety of new e-readers, and now the new iPad HD / iPad 3.  BYOD network traffic analysis is of paramount importance.

What a year so far!

You know the old saying “Time flies when you’re having fun”? Here at Plixer, our developers are so freakishly passionate about creating the NetFlow architecture of the future, the years seem to pass us by like a blur.

The hard work is really paying off! Not only were we the first company to receive Cisco certification within the Systems Management technology category but, we are proud to announce that last week we won the 2011 Golden Bridge Award for NetFlow innovations!These industry and peer awards from Golden Bridge are the world’s premier business recognition program. This award is a huge accomplishment for such a passionate group of employees. To top it all off, Cisco sent us Medianet T-Shirts!

With Cisco predicting by 2013 91% of all network traffic will be voice/video streams, we’ve been spending a significant amount of time focusing on the development of the many new Cisco Medianet performance monitoring reports. Scrutinizer v9.0 is just around the corner, it will be exciting to get feedback on all of the new reports we have built for Cisco Smart Logging and Telemetry, Cisco TrustSec, Performance Routing, Performance Monitoring and of course all of the new SonicWALL IPFIX support.

What is MediaNet?
Medianet is an intelligent end-to-end network that combines video technologies in the business, home and service provider networks. More than just higher bandwidth, it optimizes video and rich media traffic. Our solution was the first to report on the new metrics Cisco imbedded into Flexible NetFlow templates. Network traffic analysis with the advanced filtering in our NetFlow Management solution is further proof that our software provides the very best in NetFlow reporting. Read more »

I’m told that Riverbed® Cascade® Flow has introduced latency metrics to their NetFlow exports.  With this new information, we can possibly report on latency between hosts, application latency and even latency involving services in the cloud (i.e. Monitoring Cloud Performance).

In this blog I want to talk about how to configure SSL for our NetFlow and sFlow Analyzer web authentication.  The standard procedure to configuring SSL for HTTPS redirection has three basic steps.

1. Generating SSL files.
2. Installing a CA signed certificate.
3. Configuring Apache to use SSL.

A. GENERATING SSL FILES

Three files are generated as a result of this process: the private key(.key), the Certificate Signing Request (.csr), and the public key or SSL certificate (crt). The private key contains encrypted information that identifies an institution or company. The Certificate Signing request contains the information found in the private key and a public key to be signed by a Certificate Authority (CA). Read more »

What if network maps were not just a graphical representation of physical connectivity on a network?  A map in our NetFlow and sFlow Analyser is more than just a map:

• You can view the utilization  of every NetFlow exporting interface on your map.
• Links on the map are clickable. This brings up a report on traffic information for that particular connection. Information including, utilization, protocols, applications, etc, the entire scrutinizer report arsenal is available.
• Connections change color based on definable utilization thresholds.
• Google Maps can be used as a background, allowing for large scale network map based on longitude and latitude.
• Device  Icons change color based on the device status.
• You can create links to other map applications (e.g. flash maps with Visio backgrounds, WhatsUp Gold, etc). Read more »

I was working with a customer who was seeing one of their devices in Scrutinizer randomly going inactive and active on a consistent basis. After ruling out that the issue was not within the database we started analyzing the packets coming into the Scrutinizer server and what we saw was puzzling. Typically, a device in Scrutinizer that goes up and down indicates that we’re not getting NetFlow from that device during those time frames, but in this case flows were getting to the server while Scrutinizer was showing the device as inactive.
