Abstract
Some embodiments provide a system that detects whether a flow is an elephant flow; and if so, the system treats it differently than a mouse flow. The system of some embodiment detect elephants based on one or more of the following: statistics associated with a flow, packet segment size, and invoked system calls. Also, some embodiments use one or more various methods to handle elephant flows. Examples of such methods include marking each packet belonging to an elephant with a particular marking, breaking the elephants into mice, reporting the elephant to a network controller, and selectively choosing a route for each packet belonging to the elephant.
