摘要： Various exemplary embodiments relate to a system and related method for transmission of content over a telecommunications network. The system may include a deep packet inspection (DPI) device configured to perform DPI to identify an application associated with the new flow, determine an amount of bandwidth required for the application, and determine a current amount of bandwidth used by the subscriber. The DPI device may then determine a total amount of bandwidth used by the subscriber. When the total amount of bandwidth exceeds an amount of bandwidth guaranteed to the subscriber, the DPI device may perform a traffic management action on packets belonging to the new flow, such that the total amount of bandwidth used by the subscriber does not exceed the amount of bandwidth guaranteed to the subscriber.
