Five Requirements for QoS and Your Cloud Computing


I received a call today from one of the Largest Tier 1 providers in the world.  The salesperson on the other end was lamenting about his inability to sell cloud services to his customers.  His service offerings were hot, but the customers’ Internet connections were not.  Until his customers resolve their congestion problems, they were in a holding pattern for new cloud services.

Before I finish my story,  I promised a list of what Next Generation traffic controller can do so without further adieu, here it is.

  1. Next Generation Bandwidth controllers must be able to mitigate traffic flows originating from the Internet such that important Cloud Applications get priority.
  2. Next Generation Bandwidth controllers must NOT rely on Layer 7 DPI technology to identify traffic. (too much encryption and tunneling today for this to be viable)
  3. Next Generation Bandwidth controllers must hit a price range of $5k to $10k USD  for medium to large businesses.
  4. Next Generation Traffic controllers must not require babysitting and adjustments from the IT staff to remain effective.
  5. A Next Generation traffic controller should adopt a Heuristics-based decision model (like the one used in the NetEqualizer).

As for those businesses mentioned by the sales rep, when they moved to the cloud many of them had run into bottlenecks.  The bottlenecks were due to their iOS updates and recreational “crap” killing the cloud application traffic on their shared Internet trunk.

Their original assumption was they could use the QoS on their routers to mitigate traffic. After all, that worked great when all they had between them and their remote business logic was a nailed up MPLS network. Because it was a private corporate link, they had QoS devices on both ends of the link and no problems with recreational congestion.

Moving to the Cloud was a wake up call!  Think about it, when you go to the cloud you only control one end of the link.  This means that your router-based QoS is no longer effective, and incoming traffic will crush you if you do not do something different.

The happy ending is that we were able to help our friend at BT telecom,BT_logo by mitigating his customers’ bottlenecks. Contact us if you are interested in more details.
