Abstract: A network switch includes one or more queues to hold packets received from a first input flow and a second input flow. The network switch also includes a packet communication switch configured to access a first header of a first packet in the one or more queues and a second header of a second packet in the one or more queues. The first header includes first machine learning (ML) information that represents a first set of state transition probabilities under a set of actions performed at the network switch. The second header includes second ML information that represents a second set of state transition probabilities under the set of actions performed at the network switch. The packet communication switch is configured to selectively modify the first header or the second header based on a comparison of the first ML information and the second ML information.

Abstract: A node in a mesh network includes insertion circuitry to selectively delay first packets prior to insertion in a mesh network by a first time interval corresponding to a maximum failure detection time interval for the mesh network based on whether a failure has been detected in the mesh network. The node includes reception circuitry configured to selectively delay second packets received from the mesh network by a second time interval depending on whether the failure has been detected. The second time interval equals a maximum latency for the mesh network minus a sum of the maximum failure detection time interval and a propagation time along a working path. If a failure is detected, the second packets are delayed by a third time interval determined based on the maximum latency, the maximum failure detection time interval, and a propagation time along a backup path for the working path.

Abstract: Various example embodiments for supporting safe port removal are presented. Various example embodiments for supporting safe port removal may be configured to support safe port removal for a port of a virtual switch. Various example embodiments for supporting safe port removal for a port of a virtual switch may be configured to support safe removal of the port of the virtual switch such that the port is no longer available for use on the virtual switch. Various example embodiments for supporting safe port removal for a port of a virtual switch may be configured to support safe removal of the port of the virtual switch by performing separate logical and physical shutdowns of the port and performing one or more functions for the port (e.g., rejecting link discovery packets, continuing to handle data packets, and so forth) between the logical and physical shutdowns of the port.

Abstract: A network device includes processing circuitry configured to: determine whether to initiate a temporal reconfiguration or a spatial reconfiguration of a partial reconfiguration slot on a programmable device, and initiate the temporal reconfiguration or the spatial reconfiguration of the partial reconfiguration slot in response to determining that the temporal reconfiguration or the spatial reconfiguration is to be initiated.

Abstract: A network node generates a reduced size textual network log by including a set of numerical values for a log entry within a textual network log for a network, the log entry constituting an instance of a recognizable pattern within the textual network log; and then outputs the reduced size textual network log to a network controller for configuring the network.

Abstract: A processor instantiates a virtual network function (VNF) and a probe to monitor at least one metric associated with the VNF. The processor also allocates a pool of ports to the probe. A transceiver establishes one or more first interfaces between the probe and one or more applications using one or more first ports from the pool of ports. Information such as metrics generated by the ports is concurrently exchange between the probe and the applications using the first interfaces. In some cases, a second interface is established between the probe and a monitoring server. The probe reports mission critical events to the applications via the first interfaces and non-mission critical events to the monitoring server via the second interface concurrently with reporting the mission critical events.
