Abstract
Switchless deterministic data bus networks and interfaces are disclosed. In one embodiment, a network includes a switchless shared bandwidth data bus; a plurality of nodes in communication with the shared bandwidth data bus; and a deterministic transport layer hosted on each node of the plurality of nodes, the deterministic transport layer providing message scheduling and flow control, the message scheduling using a bandwidth allocation and physical layer prioritization access protocol for scheduling a packet. An embodiment of an interface includes a packager that packages data received from the host processor into packets compatible with a switchless shared bandwidth network; an un-packager that un-packs data packets received from the network, removes payload data, and transmits the payload data to the host processor; and a deterministic bus scheduler and controller that controls and schedules the transmission of data over the switchless shared bandwidth network such that the network is a deterministic network.
