Disposing individual elements within a swarm by receiving location data for swarm elements, receiving network traffic data for the swarm elements, determining new location data for a swarm element according to the location data and network traffic data of the swarm element, and sending the new location data to the swarm element.

Specifying element locations within a swarm

A system having a high speed switching interface between remote buses is disclosed herein. The system includes a switch fabric to which multiple remote bus interfaces are connected. A programmable flow queue that includes multiple parallel logic flow queues is utilized for scheduling packets in accordance with protocol requirements of the remote bus interface.

Flow architecture for remote high-speed interface application

An improved data collection method and apparatus wherein the data is accumulated in groups of storage means as the data is generated, and the data in each group of storage means is transferred to another store at a rate that is determined at least in part by the rate at which data was accumulated. In the event that data is generated faster than it is being transferred, data is not lost but data granularity is reduced. After being transferred to another store, the data is available for statistical analysis by application programs.

Method and apparatus for dynamically sampling digital counters to

The flow controller utilizes intelligent adapters to connect plural resources to a bus and a central arbiter that decides which adapters have access to the bus for the next bus cycle. Each adapter has an input buffer for transmitting data onto the bus, an output buffer for receiving data from the bus and a target register that identifies the destinations of the data in the input buffer. Each adapter communicates over control lines separate from the bus the following information: if its input buffer is nearly full, if its output buffer is either nearly empty or nearly full and the contents of its target register. The central arbiter gives highest priority to those adapters having nearly full input buffers with data for non-full output buffers, next highest priority to those adapters having nearly empty output buffers with data targeted by an input buffer and lowest priority to adapters with less than full input buffers having data for non-empty output buffers.

Flow controller for shared bus used by plural resources

A central arbiter uses priority generators to determine which resource on a shared bus has priority in accessing the bus. Each resource has a corresponding priority generator. Each priority generator has a counter having inputs and outputs. A starting value is provided at the inputs and the priority value is obtained from the outputs. Each priority generator has a comparator that compares the outputs of a counter with a modulo number of the counters, N. The priority generators provide a combination of fixed priority and round robin arbitration schemes. By selecting the value of N relative to the number of resources, the rate of round robin access relative to fixed priority access can be set.
