  • Patent number: 10817458
    Abstract: This disclosure describes techniques for extending a range of bidirectional bus communications through the use of a differential signal path. The disclosed techniques include first separating the bidirectional bus into first and second unidirectional buses that transmit and receive signals, respectively, and then communicating the signals from the first and second unidirectional buses over a differential signal path. The separation of the bidirectional bus into the first and second unidirectional buses is performed using logic circuitry that blocks or permits communication between a given one of the first and second buses and the bidirectional bus based on whichever one of the first and second buses becomes dominant first. If the logic circuitry determines that the first bus becomes dominant before the second bus, the logic circuitry permits communications between the first bus and the bidirectional bus and blocks communications between the second bus and the bidirectional bus.

  • Patent number: 10282505
    Abstract: Disclosed are methods, systems, and articles of manufacture for implementing legal routing tracks across virtual hierarchies and legal placement patterns. These techniques identify at least a layout or a portion thereof and determine one or more legal sets of routing tracks for the layout or the portion. One or more figure groups are identified or generated at a first virtual hierarchy, and the one or more first figure groups inherit respective portions of the one or more legal sets of routing tracks. A plurality of legal devices are identified in a layout or a portion thereof, and a figure group is generated at least by determining a boundary for the figure group and enclosing the plurality of layout devices within the boundary. These techniques may modify a placement row without disturbing compliance of one or more design rules with which the legal device pattern complies when generated.

  • Patent number: 10257162
    Abstract: A method is implemented by a border network gateway for enabling an end user device to access home network resources and receive subscriber services in a visited network. The method includes receiving a connection from the end user device, querying an authentication server to obtain a virtual extended local area network (VXLAN) network identifier (VNI) of the end user device, and checking for the VNI for the end user device in a demultiplexor table of the border network gateway. The process further involves determining whether the end user device is in a home network of the end user device and updating an entry in the demultiplexor table to include a media access control address for the end user device in response to determining the end user device is not in the home network of the end user device.

  • Patent number: 10230725
    Abstract: Systems and methods for edge protection for internal identity providers are provided. A first claimed embodiment of the present disclosure involves a method for edge protection for internal identity providers. The method includes receiving a service authentication request at a virtual private networking (VPN) appliance on an edge of a secure network. A client device external to the secure network can send the service authentication request. The VPN appliance can then send a synthetic service authentication request to an identity provider in the secure network. This synthetic service authentication request can be based on the service authentication request. The VPN can then receive an authenticated credential from the identity provider. The authenticated credential is responsive to the synthetic service authentication request. The VPN appliance can then send the authenticated credential from the VPN appliance to the client device.
