Abstract

A system for regulating packet flow through a switch fabric and a system for verifying the transmission integrity of the fabric. In the first system, an ingress sends packets to the switching entity in a designated order and an egress receives packets from the switching entity, re-orders the packets in the designated order and sends an acknowledgement of receipt of the packets to the ingress upon re-ordering. The ingress receives acknowledgements of receipt of packets from the egress, maintains an indication of a number of packets for which an acknowledgement of receipt has not yet been received, performs a comparison between the number of packets for which an acknowledgement of receipt has not yet been received and a threshold, and regulates sending packets to the switching entity on the basis of the comparison. The principle behind the second system is based on exchanging marker packets at identifiable reference instant.
