Abstract: A cost effective congestion isolation for lossless Ethernet utilizing random selection is provided. Upon detecting congestion at one of its egress ports, a downstream device randomly selects a data packet received at one or more of its ingress ports for isolation in a congested priority queue at the ingress port. The downstream device sends a congestion isolation message, including a list of isolation hashes to an upstream device to identify data packets selected for isolation. Upon receipt, the upstream device identifies data packets selected for isolation and begins to queue such packets in a congested priority queue of the upstream device. When priority-based flow control is triggered, the upstream device ceases transmission of packets in the congested priority queue only, while allowing continued transmission of non-isolated data packets.

Abstract: A device and corresponding method are provided determining a consumed computing capacity of a first networking device exceeds the threshold for total capacity for processing monitoring data for a monitoring metric. An optimization engine determines a second networking device with unused computing capacity sufficient for processing the monitoring data generated by the first networking device. The optimization engine automatically moves the monitoring data for the monitoring metric generated by the first networking device to the second networking device and causes the second networking device to process the monitoring data.
