    Abstract: A system and method predict risks of failure or performance issues in a network to predictively position traffic flows in the network. For a traffic flow through a network, first data accumulated in a header of packets for the traffic flow is obtained, which header is populated by network elements along a path of the traffic flow through the network. Second data is obtained about the network in general including other network elements not along the path of the traffic flow. Machine learning analysis is performed to derive rules that characterize failure or performance risk issues in the network. The rules and topology data describing a topology of the network are applied to a model to create a topological graphical representation indicating failure or performance issues in the network that affect the traffic flow. A path for the traffic flow is modified based on the topological graphical representation.

    Abstract: Systems, methods, and computer-readable media are disclosed for use of an overlay network termination endpoint as a proxy to collect telemetry data for micro-services or specific applications provided by containers in overlay data centers. In one aspect of the present disclosure, a method includes receiving, at a controller, a probe for flow statistics associated with a service path, the probe including corresponding flow identification information, extracting the corresponding flow identification information from the probe, obtaining the flow statistics from an agent based on the flow identification information, the agent being configured to manage a plurality of containers, generating a response packet including the flow statistics obtained from the agent and sending the response packet to an initiator from which the query is received.

    Abstract: Techniques for use in generating a dynamically-changing IoT device identity with robust blockchain validation are provided. When entering a communication network, an IoT device performs a procedure for registration. The procedure includes communicating, in a transaction, data associated with the IoT device to a network device (e.g. a fog router). The data includes, amongst other data items, an identity for addressing communications to and from the IoT device. A transaction number associated with the transaction is received based on a blockchain registration of the transaction. An updated identity of the IoT device is then derived based on the transaction number. In one example, the updated identity of the IoT device may be derived by combining a static address of the IoT device and the transaction number. The steps may be repeated by the device for each one of a plurality of network registrations.
