Method for data throughput improvement in open core protocol based interconnection networks using dynamically selectable redundant shared link physical paths

Abstract

Methods and apparatus for facilitating data throughput improvements in interconnect fabrics employing point-to-point links using dynamically selectable routing. Initiators and targets are operatively coupled to first and second fabrics. The first and second fabrics include multiple point-to-point internal links and are communicatively coupled to one another via multiple fabric-to-fabric links, including first and second links from the first fabric to the second fabric. During operations, traffic on the first fabric-to-fabric link is detected to determine if it is busy, and depending on the determination, data transfers from an initiator coupled to the first fabric destined for a target coupled to the second fabric are selectively routed via either the first or second fabric-to-fabric links.
