1. A system comprising:

  • a data collection module configured to collect data belonging to a plurality of traffic flows from a plurality of routers;

    a controller; and

    an analytics module configured to;

    received data from the data collection module,retrieve from a policy data base a set of policy rules for a traffic flow among the plurality of traffic flows,determine if any data packets belonging to the traffic flow matches a first policy rule within the set of policy rules,in response to determining that the traffic flow satisfies the first policy rule, send policy compliance information about the traffic flow to the controller,wherein the controller is configured to;

    receive policy compliance information about the plurality of traffic flows from the analytics module, andin response to receiving policy compliance information about the traffic flow from the analytics module, configure one or more routers to transmit a first portion of the traffic flow to a network service providerin response to determining that the traffic flow satisfies a second policy rule, send a request to receive a second portion of the traffic flow, wherein the second portion of the traffic flow comprises a larger amount of information than the first portion of the traffic flow; and

    in response to receiving the second portion of the traffic flow, inspect the second portion of the traffic flow at a second level of detail, wherein the inspecting at the second level of detail requires a different amount of computing resources than the inspecting the first portion of the traffic at the first level of detail.
