  • Patent number: 10594512
    Abstract: A transport network employs dual homing to an access network to provide connectivity from multiple network switches. Dual homing is a mechanism by which an access network employs pair of switches in the transport network as if it were connecting to a single device. Conventional arrangements for defining multiple paths from a transport network to an access network suffer from the shortcomings of potential routing loops, increased hops to the access network, and inability or inconsistency with forwarding to different types of access networks, and may involve redirecting traffic absent faults in the access network. The dual homed network switches identify the type of access network and perform switching logic corresponding to the access network type to provide comprehensive dual-homed support to the access network independently of the type of transport employed in the access network, and employ redirection only if there is a fault in the access network.

  • Patent number: 8565230
    Abstract: Embodiments herein include systems and methods for providing a mechanism for tunneled data transport within a dual homed access network. A tunnel manager, at a first network connectivity device in a transport network, identifies the transport network configured to interconnect at least two access networks for transporting data traffic between one or more end stations connected to the access networks. The first network connectivity device is coupled to a first access network. The tunnel manager identifies a second network connectivity device. The second network connectivity device is coupled to the first access network to provide the first access network dual homed access to the transport network via the first and second network connectivity devices. The tunnel manager creates a virtual tunnel that connects the first and second network connectivity devices to a third network connectivity device across the transport network.

  • Patent number: 8232785
    Abstract: A programmable AC/DC or DC/DC power supply adapted to compensate for voltage drop in a cable extending to a portable electronic device. The invention reduces the number and size of cable wires and tip components needed to remotely control an output voltage level and an output current limit. The voltage and current programming components are outside the compensation feedback loop.

  • Patent number: 8093875
    Abstract: A method for cable resistance cancellation. A single remote sense line and a simple cable resistance cancellation network are leveraged in a power supply unit to compensate for the total cable voltage drop, while maintaining tight output accuracy. By completely compensating for the voltage drops, the wire gauge for the main power wires can be reduced, thereby allowing the use of smaller diameter cables.
