Method and systems for QoS-aware flow control in communication networks, corresponding network and computer program product

摘要

Transmitting data in an Ethernet network including nodes that support differentiated queues for different Classes of Service and queue congestion handling, involves the steps of recognizing at one node in the network that a given queue for a given Class of Service is congested, and causing the node to send to another node in the network pause frames that explicitly identify that queue for a given Class of Service as congested.The node receiving the pause frames may then control the transmission rates for different outbound queues towards the first node according to the congestion information carried by the pause frames.
