System and method for detection of elephant flows

摘要

A system and method for detection of elephant flows includes a switching device. The switching device includes one or more ports, a memory, and a control unit coupled to the ports and the memory. The control unit is configured to detect storage locations information included in one or more first messages. The storage locations information identifies a storage node and is forwarded to a computing device. The control unit is further configured to detect opening of a connection between the computing device and the storage node based one or more second messages received for forwarding on one or more of the ports and determine identifying characteristics of an elephant flow based on information associated with the connection. In some embodiments, the control unit is further configured to forward network packets using an altered forwarding strategy when the network packets are associated with the elephant flow.

1. A switching device comprising:
one or more ports; a memory; and a control unit coupled to the ports and the memory, the control unit being configured to:
detect an elephant flow between a computing device and a storage node;receive one or more first network packets at the switching device;determine whether the first network packets are associated with the elephant flow; andforward the first network packets as elephant flow packets when the first network packets are associated with the elephant flow;wherein to detect the elephant flow, the control unit is configured to:
detect storage locations information included in one or more first messages received for forwarding to the computing device on one or more of the ports, the storage locations information including an address of the storage node and one or more storage locations within the storage node;detect subsequent opening of a connection between the computing device and the storage node based on one or more second messages received for forwarding on one or more of the ports; anddetermine as identifying characteristics of the elephant flow, one or more properties that identify the connection;wherein to determine whether the first network packets are associated with the elephant flow, the control unit is further configured to determine whether characteristics of the first network packets match the identifying characteristics of the elephant flow.
