I love my job, but I really don’t enjoy my commute….and the unpredictable traffic. Living on the west side of San Francisco and working on the east side of San Jose, Google Maps tells me my journey is a hefty 47.2 miles and 1 hour and 1 minute (without traffic.) Holidays, rain, and accidents can add minutes and sometimes hours.

Twice a day, to and from work, I start asking the questions:

My solution: a customized app just for me, “SarahTrafficApp” –  it provides visibility into how busy the road is and the types of vehicles, and giving ME priority, will tell me which lane to be in and if I need to detour to another freeway. If SarahTrafficApp sees that there is an unusual number of SUVs sporting 49ers flags and heading to Candlestick Park, it tells me to exit and journey to the parallel freeway. When I’m on the right route, SarahTrafficApp tells me which lane will be the fastest. One hour and 1 minute, here I come!

That’s my commute: traffic is a problem. In contrast, traffic on my network is not a problem with something we introduced not too long ago called Cisco Application Control and Visibility (AVC.)

AVC can help you determine:

For users of the network, this means a better application experience – video streaming quality up, ability to work more efficiently in a virtual desktop session, and no more VoIP skipping during conference calls. For network administrators, this means you can save bandwidth by not letting your network get swallowed up by non-work applications such as P2P or gaming traffic. You can also cut down on those pesky support calls from folks having a catastrophic application experience.

How does AVC work? It’s a solution based on:

I like imagining this world without bad traffic, and if it can’t happen on the road, let’s let it happen in the network. For a demonstration of AVC, watch our video. And then visit the AVC page at for more details.

    I work mostly on the reporting side of Flexible NetFlow for NBAR, Performance Monitoring and Performance Routing. We have implemented all of these technologies on our network and the metrics for determining performance are very insightful.

    NBAR2 extends ~150 applications recognized by NBAR to close to ~1000 applications. ISR G2 also now provides more advanced metrics such as application response time that can also be reported.


  3. is it possible to configure PfR for Netflow collectors. if yes then please let me know what are the fields Exported by router to a collector and how to configure router for expotring PfR.
