Abstract
Systems and methods are disclosed for classifying traffic flows. A traffic agent operable to collect classification information for one or more traffic flows may be deployed at an end host communicatively coupled to a data-center network. The traffic agent, deployed in a user space independent of the operating system, may compare the classification information for a given traffic flow to a metric value. Where the classification information achieves a certain threshold indicated by the metric value, the traffic agent may classify the traffic flow as an elephant flow. In some examples, a library may be included with the traffic agent that may include a modified send function. The modified send function may provide classification information to the traffic agent indexed to the traffic flow for which it is called so that the traffic agent may analyze the classification information to potentially provide a classification for the traffic flow.
