  • Patent number: 11516122
    Abstract: Systems and methods for detecting, testing, and validating inactive paths or backup/protection paths of Label Switched Paths (LSPs) in a Multiprotocol Label Switching (MPLS) network are provided. A method, according to one implementation, includes the step of identifying an active path defining a traffic route along which data packets are transmitted from an ingress node to an egress node via one or more intermediate nodes. The method also includes sending an echo request from the ingress node to the one or more intermediate nodes, wherein the echo request allows the one or more intermediate nodes to detect and validate one or more inactive paths. The one or more inactive paths are configured as one or more protection paths when an event is detected that impedes the transmission of the data packets along the active path.

  • Publication number: 20220070085
    Abstract: Systems and methods include receiving a traceroute packet at a relay node; responding to the traceroute packet with a first data structure inside the traceroute packet that indicates a propagation mode at the node and an operation type performed at the node, receiving subsequent traceroute packets from the initiator node with a second data structure inside the subsequent traceroute packets with data used to indicate changes in a header of the subsequent traceroute packets, and forwarding the subsequent traceroute packets with the changes to the header based on the data. The systems and methods can include utilizing the first data structure to determine the changes in the header of the subsequent traceroute packets. This can be used in Multiprotocol Label Switching (MPLS), Segment Routing (SR), and Internet Protocol (IP), where a TTL/Hop Limit propagation is limited.

  • Publication number: 20220048856
    Abstract: The present application relates to a method (I) for preparing a brivaracetam intermediate, comprising the steps of dissolving the compound represented by B-P and 1S,2S-diphenylethylenediamine in a solvent for resolution, crystallizing, filtering, and recrystallizing to obtain the compound represented by B-Q, which is then converted to the brivaracetam intermediate represented by B-R. This method can effectively resolve the compound represented by B-P. The present application also provides a method for preparing brivaracetam using the compound represented by B-R. The method can separate the effective components only through simple steps such as extraction, washing, drying, and concentration without requiring use of chiral chromatography column to separate isomers in the preparation process, and thus the separation process is simple, greatly reducing the production cost of brivaracetam.

  • Patent number: 11087071
    Abstract: Systems and methods for a self-compressed YANG (Yet Another Next Generation) model allow a model data provider (e.g., a client that provides configuration information to a server, or a server that provides response data to a query) to dynamically select either text format or compressed format using the same data model. This approach can significantly increase the YANG management performance of both network elements and servers (e.g., Operations, Administration, and Maintenance (OAM) devices). The self-compressed YANG model maintains full compatibility to existing standards/implementations, namely, the enhanced compression is available where supported.

  • Patent number: 10988842
    Abstract: A two-dimensional transition-metal dichalcogenide layer is grown by reacting a non- or low-volatile source material with a volatilized halogen or halide compound to produce a volatilized composition comprising at least one reaction product. The volatilized composition is flowed through an open chamber of a tube furnace with a temperature gradient, wherein the temperature changes along a path through which the volatilized composition flows through the open chamber of the tube furnace. Where the temperature along the path in the open chamber is in a reaction-temperature range, the volatilized composition is deposited as a two-dimensional crystalline transition-metal dichalcogenide layer.
