An adaptive weighted arbitration algorithm that is user configurable is discussed. The arbitration logic and algorithm considers past arbitration history events and is dynamic to allow for losing bidders to increase their probability of being selected to access the resource based on an accumulator value and a weight value.

Method, system, and apparatus for an adaptive weighted arbiter

Multiple boards are connected within a chassis, using a multi-port Target Channel Adapter (TCA). Data is transported from a TCA on a board directly to a TCA on another board through a meshed backplane. The meshed backplane is equipped to mount boards via connectors and may consist of a fabric of copper conductors or optical fibers. Communication from TCA to TCA requires placing ports on each individual TCA along with the appropriate input and output buffering. A multi-port TCA capable of performing multiple bridging functions simultaneously i.e., bridging from a high speed serial meshed backplane to multiple local busses, i.e., Gigabit Ethernet, Fibre Channel, and TCP/IP devices, is referred to as a Fabric Interconnect Chip (FIC).
