Abstract: Embodiments of the invention provide systems, devices and methods to schedule data transport across a fabric, e.g., prior to actual transmission of the data across the fabric. In some demonstrative embodiments, a packet switch may include an input controller to schedule transport of at least one data packet to an output controller over a fabric based on permission information received from the output controller. Other embodiments are described and claimed.

Abstract: A system for switching variable size packets in a network is disclosed. The system comprises at least one ingress controller which receives a plurality of packets and which segments each of the packets into fixed sized fragments. The at least one ingress controller has a time-clock. The time clocks of all ingress controllers are synchronized to within a tolerance. Each fragment is tagged with at least a unique source of ID, time-stamp, and a fragment-number to form a cell. Each cell belongs to one packet having the same time-stamp value. The ingress controller sends each of the cells through a link such that a cell's destination is reachable through that link. The system includes a fabric element which receives cells from a plurality of inputs links. The cells are ordered. The fabric element sends ordered cells through a plurality of outputs and through which the destination of the cells is reachable.
