A disclosed method may include (1) identifying, by a PE router, a conditional advertisement policy that requires installation of at least one address of an active service appliance within a routing table to trigger advertising a route for the active service appliance to one or more additional PE routers, (2) inspecting the routing table for the installation of the address of the active service appliance, (3) determining, based at least in part on the inspection, that the address of the active service appliance is installed in the routing table, (4) determining that the PE router has satisfied the conditional advertisement policy due at least in part to the address of the active service appliance being installed in the routing table, and then in response, (5) directing the PE router to advertise the route to the additional PE routers. Various other apparatuses, systems, and methods are also disclosed.

Apparatus, system, and method for achieving shortest path forwarding in connection with clusters of active-standby service appliances

Positive logic circuits, systems and methods using MOSFETs operated in a depletion-mode, including electrostatic discharge protection circuits (ESD), non-inverting latches and buffers, and one-to-three transistor static random access memory cells. These novel circuits supplement enhancement-mode MOSFET technology and are also intended to improve the reliability of the complementary metal-oxide-semiconductor (CMOS) integrated circuit (IC) products.

Depletion-mode MOSFET circuit and applications

A system and method for detecting a phase and a frequency and an arrival-time difference between two signals (and) that minimizes delay and jitter, and has stable operation even when the two signals (and) are essentially identical. The system includes two single-ended charge-pump (), phase-frequency detection (PFD) circuits (). The first PFD is stable when a reference signal, supplied to a polarity determining flip-flop, leads the signal to be synchronized. A second, complementary, PFD circuit is stable, but has an inverted polarity output, when the signal to be synchronized, supplied to a polarity determining flip-flop, leads the reference signal. A polarity-selection logic-circuit () ensures that the first activated PFD controls the polarity a single-ended charge pump () for a time-period determined by the delay between the activation of the polarity determining and non-polarity determining flip-flops of the selected PFD.
