Abstract: A service to provide anomaly detection receives a request to back-test the service. The request includes information for accessing a dataset of historical data. The service executes workflows to ingest the data, train a plurality of machine learning models to perform anomaly detection, and detect anomalies in the dataset. A representation of the detect anomalies is generated and presented to a user. The service receives an indication to activate the service to provide ongoing anomaly detection services.

Abstract: Systems and methods for enabling Bidirectional Forwarding Detection (BFD) over a selected reverse path are provided. A process, according to one implementation, include sending an echo request in a forward direction from an initiator node to a reflector node. For example, the initiator node and reflector node may be configured to operate in a network having no or different centralized controller that manages both the initiator node and reflector node. The echo request may be sent to the reflector node to discover a reverse path in a reverse direction from the reflector node to the initiator node. Also, the reverse path is discovered for the purpose of initiating a Bidirectional Forwarding Detection (BFD) or Multi-Protocol Label Switching (MPLS) Ping procedure.

Abstract: Systems and methods for monitoring the continuity between endpoints in a network are provided. A process, according to one implementation, includes entering a first list of one or more Segment Identifiers (SIDs) into a Bidirectional Forwarding Detection (BFD) request packet, the first list of one or more SIDs defining a Segment-Routing Traffic-Engineering (SR-TE) forward path from a source node to a destination node. The process also includes entering a second list of one or more SIDs into the BFD request packet, the second list of one or more SIDs defining an SR-TE reverse path back from the destination node that eliminates involvement of a BFD reflector of the destination node. Also, the process includes entering a revised-BFD request into the BFD request packet, the revised-BFD request having a Your Discriminator field set to a discriminator value associated with the source node.

Abstract: A tennis training apparatus suspends a tennis ball in the air to allow a player to practice striking the ball with a tennis racquet. The apparatus includes a tennis ball with a first magnetic element integrally and non-removably coupled to the tennis ball. The tennis ball includes an outer layer, an inner core and an intermediate layer positioned between the outer layer and the inner core. A panel is provided. A magnet is coupled to the panel. The first magnetic element of the tennis ball is positionable adjacent to and magnetically attractable to the magnet wherein the tennis ball is releasably couplable to the magnet. A support assembly is coupled to the panel. The support assembly is configured to support the panel above a ground surface.
