Abstract: In one embodiment, a processor-readable medium storing code representing instructions that when executed by a processor cause the processor to update, at a memory location, a first flow state value associated with a data flow to a second flow state value when at least one of a packet from the data flow is received or the memory location is selected after a time period has expired. At least a portion of the packet is analyzed when the second flow state value represents a flow rate of a network data flow anomaly.

Abstract: In some embodiments, an apparatus includes a forwarding module that is configured to receive a group of first data packets. The forwarding module is configured to modify a data flow value in response to receiving each first data packet. The forwarding module is also configured to store each first data packet in a first output queue based on the data flow value not crossing a data flow threshold after being modified. Furthermore, the forwarding module is configured to receive a second data packet. The forwarding module is configured to modify the data flow value in response to receiving the second data packet, such that the data flow value crosses the data flow threshold. The forwarding module is configured to store the second data packet in a second output queue based on the data flow value having crossed the data flow threshold.

Abstract: In some embodiments, an apparatus includes a switch fabric having at least a first switch stage and a second switch stage, an edge device operatively coupled to the switch fabric and a management module. The edge device is configured to send a first portion of a data stream to the switch fabric such that the first portion of the data stream is received at a queue of the second switch stage of the switch fabric via the first switch stage of the switch fabric. The management module is configured to send a flow control signal configured to trigger the edge device to suspend transmission of a second portion of the data stream when a congestion level of the queue of the second switch stage of the switch fabric satisfies a condition in response to the first portion of the data stream being received at the queue.

Abstract: A method of sending data to a switch fabric includes assigning a destination port of an output module to a data packet based on at least one field in a first header of the data packet. A module associated with a first stage of the switch fabric is selected based on at least one field in the first header. A second header is appended to the data packet. The second header includes an identifier associated with the destination port of the output module. The data packet is sent to the module associated with the first stage. The module associated with the first stage is configured to send the data packet to a module associated with a second stage of the switch fabric based on the second header.
