Abstract: A method for reducing transmission of telemetry packets includes receiving, at a network controller, telemetry packets from network nodes in a communication pathway of data packets being transmitted from a sending host to a receiving host and determining from the telemetry packets a number of network nodes in the communication pathway. The method includes setting a network node threshold value equal to the determined number of network nodes in the communication pathway, and transmitting, from the network controller, the network node threshold value to each network node in the communication pathway.

Abstract: Methods, apparatuses, and computer program products for telemetry-based network switch configuration validation are disclosed. An analytics engine captures a first network snapshot including telemetry data received from one or more network switches in a first state. Upon receiving a notice indicating that a network configuration change has been applied, the analytics engine initiates a timer in response to receiving the notice. The analytics engine captures, in response to expiration of the timer, a second network snapshot including telemetry data received from the one or more network switches in a second state and compares the first network snapshot and the second network snapshot. In dependence upon the comparison of the first network snapshot to the second network snapshot, the analytics engine validates the network configuration change.

Abstract: An apparatus includes a controller adds telemetry data to a telemetry packet transmitted along a communication pathway for data packets being transmitted from a sending host to a receiving host. The controller determines, from the telemetry packet, a number of network nodes in the communication pathway that have added telemetry data to the telemetry packet. The controller transmits the telemetry packet to a next destination along the communication pathway and to a network controller in response to determining that the number of network nodes in the communication pathway that have added telemetry data to the telemetry packet is equal to or greater than a network node threshold. The controller just transmits the telemetry packet to the next destination in response to determining that the number of network nodes in the communication pathway that have added telemetry data to the telemetry packet is less than the network node threshold.

Abstract: An apparatus includes a processor and a memory that stores code executable by the processor to transmit a passenger status message in response to a trigger event indicative of a passenger failing to be picked up at a pickup location by a ride service vehicle. The passenger status message is transmitted to a passenger mobile communication device and a driver. The code is executable to transmit a help message to members of a passenger trusted list in response to receiving a reply to the passenger status message from the passenger indicative of a request for help by the passenger. The code is executable to transmit to a police agency a police request to assist the passenger in response to a trusted list timeout, which is indicative of not receiving a message from a member of the passenger trusted list that indicates the passenger is okay before the trusted list timeout.

Abstract: An apparatus for machine learning for workloads for ISA optimization is disclosed. The apparatus includes a processor and a memory that stores code executable by the processor. The executable code is executable to run program code to service a workload with a default instruction set of the processor, identify an instruction sequence from execution results for the workload, the instruction sequence called repeatedly during execution for the workload, and generate a custom instruction that includes the instruction sequence. The executable code is executable to write the custom instruction to a writable area of processor memory storing the default instruction set, recompile program code used to service the workload, where the recompiled program code includes the custom instruction, and run the recompiled program code to service the workload.

Abstract: An apparatus for in-band telemetry includes a node type identifier circuit that, in response to receiving an ingress/egress ID command, determines that the network node is an ingress node in response to the network node having a direct connection to a source and determines that the network node is an egress node in response to the network node having a direct connection to a destination. The apparatus includes a telemetry packet circuit that creates a telemetry packet in response to the node type identifier circuit determining that the network node is an ingress node. The apparatus includes a telemetry transmission circuit that transmits the telemetry packet in response to the telemetry packet circuit creating the telemetry packet and a packet re-router circuit that, in response to the node type identifier circuit determining that the network node is an egress node, routes a received telemetry packet to a network controller.

Abstract: A stack switch for performing pass-through forwarding operations, assigning stack switch identifiers to a plurality of stack switches, temporarily disabling supervision messages exchanged by stack switches, and electing a primary master stack switch is disclosed. In the pass-through mode, the stack switch automatically forwards packets between stack ports independent of their destination address to maintain connectivity between adjacent stack switches while conventional bridging and routing operations are disabled. The sequential identifiers are also preferably assigned in accordance with the sequential position of the various stack switches to better reflect the topology of those switches. The switch is also preferably adapted to temporarily disable the transmission of supervision messages between stack switches to prevent re-assignment of network management functions when switch resources are low.
