DBM is the latest generation of our equalized traffic shaping technology. This feature ensures that no individual or small group of users is able to saturate the WAN links with so much application traffic that other users are unable to effectively utilize the Internet and other cloud-based services.
Instead of attempting to classify every application which may be used by an end user the EdgeXOS platforms takes a different approach by tracking the session information and usage per session. By tracking session information rather than the application layer data the EdgeXOS appliance is able to stay ahead of changes to peer-to-peer and other recreational applications and thus provide a better shaping solution.
This is the ability to track client connections based on their unique session IDs and certain other characteristics which can uniquely identify the specific connection. Once identified the session is tracked for overall usage as compared to other sessions traversing the EdgeXOS appliance.
When sessions meet specifically defined criteria they are shaped in order to maintain fair queuing for all other applications. This shaping is dynamic and ensures that top users do not over-utilize the available network bandwidth to the degree that other users become unresponsive.
The difference between session tracking and application classification is that application classification requires constant updates to a large database of applications. These updates often come out weeks of not months after a new version of the application comes out, which means that in some cases end-users can find ways to get around application classification shaping appliances by simply upgrading to the latest version.
Furthermore, some methods for classifying applications will not work with the more sophisticated methods being employed by the latest peer-to-peer applications. Unlike application classification, session tracking does not care how the application is defined, only that the session appears to be utilizing more than it's fair share of bandwidth, and thus needs to be throttled. This process guarantees more bandwidth for more end-users and thus prevents most network congestion issues.
