Internet & WAN Application Guarantees
Automatic QoS rules to protect your important applications
NetScope can automatically detect which applications you have running and protect them from delays. Large file transfers, video streaming, database updates can cause delays for VoIP, video conferencing and your cloud CRM applications. The benefits automatic QoS are:
- Stop delays on VoIP calls
- Stop delays on video conferences
- Stop the bandwidth creep
- Ensure your Internet connection is used efficiently and protect it against any unforeseen traffic spikes
Unique Flow Level QoS
Per-Flow level QoS
NetScope has improved the QoS algorithm so that rules are applied at the flow level, rather than the class level. QoS traditionally works by adding packets to the end of packet queues for each class. At times of congestion these queues get quite long. Any new flow arriving must fight against already well established queues.
Per-Flow level improves QoS
How is flow level QoS better than class level QoS?
Every flow is treated fairly and is given an equal portion of the bandwidth available to that class, instead of being added to the very back of the whole class queue. This means that each flow gets a fair share of the bandwidth as soon as it is required. This ensures a higher level of QoS.
A QoS Example
What does traffic congestion mean?
When Interent traffic passes in and out of your network there is very little in the way of rules and right of way. Video streaming or a large file download has the same right of way as video conferencing or VoIP. What this means is that even if you have a large bandwidth Internet link bandwidth hogs will still impact VoIP and video conferencing quality.
Large Delays caused by Traffic Hogs
In this chart we are showing CRM traffic and its delays in milliseconds. When there are large amounts of traffic from the traffic hogs you will see the RTT increase.
HINT: Enable the traffic hogs by clicking their corresponding legend item (OneDrive, Web, Video Streaming). You will see how their traffic spikes correlate to the large delays.
Delays Reduced After QoS
After a QoS rule is implemented on all CRM traffic we can see that RTT times (delays) are drastically reduced.
