    Abstract: A first flowlet of a flow from a source network device to a destination network device is assigned to a first path of a plurality of paths between the source device and the destination device. The assignment of the first flowlet to the first path is made by a network connected device. A second flowlet is detected in response to an interruption in transmission of the flow due to congestion along the first path, wherein the interruption is longer in duration than a difference in a transmission time between the source network device and the destination network device along each of the plurality of paths. The second flowlet is assigned to a second path of the plurality of paths by the network connected device. According to some example embodiments, the second path is randomly selected from the plurality of paths.

    Abstract: In one embodiment, a next set of packets in a first flow may be identified. A counter may be incremented, where the counter indicates a first number of initial sets of packets in first flow that have been identified. The identified next set of packets may be prioritized such that the first number of initial sets of packets in the first flow are prioritized and a sequential order of all packets in the first flow is maintained. The identifying, incrementing, and prioritizing may be repeated until no further sets of packets in the first flow remain to be identified or the first number of initial sets of packets is equal to a first predefined number.

    Abstract: Systems, methods, and non-transitory computer-readable storage media for per-packet load balancing in a port channel. The system first maps an incoming traffic flow to queues containing packets to be transmitted through a port channel at the system, the port channel including ports grouped into a single virtual port. Next, the system assigns a port from the port channel to a queue for a predetermined period of time, wherein the port is assigned to the queue based on at least one of a port state and a service history associated with the queue. The system then de-queues at least a portion of the packets in the queue through the port for the predetermined period of time. This load balancing can ensure that traffic is efficiently and fairly load balanced across the links of the port channel, and packets of each queue are not reordered.

    Abstract: Systems, methods, and computer-readable media are provided for determining whether a node in a network is a server or a client. In some examples, a system can collect, from one or more sensors that monitor at least part of data traffic being transmitted via a pair of nodes in a network, information of the data traffic. The system can analyze attributes of the data traffic such as timing, port magnitude, degree of communication, historical data, etc. Based on analysis results and a predetermined rule associated with the attributes, the system can determine which node of the pair of nodes is a client and which node is a server.
