    摘要: This application describes how Session Description Protocol (SDP) preconditions signaling can be enhanced to support lead role negotiation, precondition capability exchange, premature precondition attempts and concatenated preconditions processing. The application describes the use of send and receive tags in an SDP message for a given media line. In a given message, a success or failure tag may be associated with a send or receive tag in addition to an optional or mandatory condition indicator tag. A lead role indicator may also be associated with a send or receive tag to indicate a desired preference with regard to the sender or receiver taking the lead role. These additions lead to a greater chance of successful session set-up completion, reduce the number of signaling exchanges in general, and enable precondition attempts to be started earlier and to be executed in parallel.

    摘要: Various methods and apparatus are directed to providing enhanced functionality and fault tolerance in a system which distributes home agent functionality between a home agent control node and a tunneling node, referred to herein as a home agent tunneling node, which performs packet forwarding under direction of the home agent control node. The distributed home agent approach is enhanced in some embodiments to provide redundancy of home agent control nodes and/or home agent tunneling nodes. Thus, in accordance with some embodiments if a home agent control node fails, the secondary home agent control node can take over the home agent control function. Various embodiments describe various methods, apparatus, and/or messages in addition to system configurations, which can be used to maintain primary and secondary home agent control and facilitate a rapid transfer of functions between primary and secondary nodes.

    摘要: A hybrid electric vehicle with two separate drive systems. High speed operation is powered by self frequency ramping alternating current motors 107 within the wheel rims. Low speed operation is powered by hydraulic motors 102 directly coupled to the drive wheels. The hydraulic oil is pressurized by direct current motors/pumps 302 & 309 energized by a battery pack 106. The alternating current motors 107 are energized by mechanical or electronically generated alternating current. The hybrid power source is either a combustion engine 406 driving a poly-phased alternator 501 or a fuel cell 600 providing direct current. In the case of the combustion engine 406, a direct current helper motor/generator 404 will augment the engine with power from the battery pack 106 under large demands and charge the battery pack 106 under small demands. In the case of a fuel cell 600, the cell is augmented by the battery pack 106 under large demands and charges the battery pack 106 under small or no demands.
