A method of searching for a shortest path from a single source node to a single destination node in a two dimensional computer network. The method is similar to Dijkstra shortest path algorithm (“Dijkstra”) in the way it builds a shortest path tree. However, instead of starting from the source node and searching through to the destination node as Dijkstra does, the method runs a shortest path search from both ends (i.e. source and destination) simultaneously or alternatively, until a shortest path tree from one end meets a shortest path tree from the other end at an intermediate node, and the concatenated path (source node intermediate node-destination node) satisfies a condition. Conditions other than those used by Dijkstra determine when the search should terminate, and whether the search has succeeded or failed. It has been verified that the new method requires less overhead and time than Dijkstra.

A satellite communications system (10) includes a hub (14), a satellite (32), and any number of remote terminals (16). Each remote terminal (16) includes a remote receiver (38), a monitor (40), and a network access controller (42). Each remote receiver (38) is configured to receive and down convert the system's entire spectrum of interest from which channels are accessed by the remote terminals (16). The monitors (40) independently perform FFT processes over this entire spectrum, but at a low frequency resolution which is no higher than needed to distinguish channels. Based on these spectral analyses, uplink / inbound channels are independently selected by the network access controllers (42) at each remote terminal (16). Remote terminals (16) immediately transmit data to the hub (14) as soon as they select an uplink / inbound channel.

A system for reducing current leakage in an integrated circuit. The system includes a first circuit component and a second circuit component in a path between a high voltage state and a low voltage state, such as ground. A feedback mechanism selectively provides feedback from an output of the second circuit component to an input of the first circuit component to selectively cutoff the path at the first circuit when the path is not cutoff at the second circuit. In a more specific embodiment, feedback mechanism preserves data in the integrated circuit via a multiplexer that selectively enables the feedback when the integrated circuit is in sleep mode. The first and second circuit components are High Voltage Threshold (HVT) CMOS inverters. The feedback path is chosen so that when the feedback path is activated, leakage paths through the CMOS inverters are cutoff.

An internal voltage generator is highly tolerant of electrical parameter changes of transistors occurring due to process deviation.

In one embodiment, the internal voltage generator of the present invention includes a comparator block and an output driving block to produce an internal voltage. The internal voltage generator further includes a reference voltage generation block, which generates at least two reference voltages to be supplied to the comparator block, and an offset section control block, which supplies a control signal for optimizing an offset section, that is, a voltage difference between the reference voltages, to the reference voltage generation block. The internal voltage generator can further optionally include an auxiliary output driving block in addition to a main output driving block to reduce the setup time for which the internal voltage is produced when voltage is initially supplied and to reduce power consumption. The internal voltage generator further includes a first control signal generation block and a control block to control operations of the main and auxiliary output driving blocks.

The present invention relates to a system for implementing resource allocation in network communication and a method thereof. It effectively solves the end-to-end QOS problem through dividing a communication network into a plurality of QOS domains and managing them. In the present invention, only end-to-end path information is maintained at the QER of the QOS domain that is directly connected with the source / destination terminal, while only edge-to-edge resource reservation information for aggregate flows is maintained at other QERs, thus significantly reducing flow state information maintained at the network nodes as well as overhead of signaling protocol processing and storage at the network nodes.
