A system for facilitating an integrated traffic profile for indicating congestion and packet drop is provided. During operation, the system can determine a first traffic profile indicating whether to drop a packet based on the utilization of a queue. The packets from the queue can be forwarded via an egress port reachable via a fabric. The system can also determine a second traffic profile indicating whether to indicate congestion in the packet based on the utilization. The system can then determine a third traffic profile by combining the first and second traffic profiles. The third traffic profile can indicate acceptance at the queue for a subset of packets being selected for dropping based on the utilization. Subsequently, the system can, if the packet is selected for dropping, determine whether to accept the packet at the queue and set a congestion indicator in the packet based on the third traffic profile.

Integrated traffic profile for indicating congestion and packet drop for congestion avoidance

A system for facilitating an enhanced traffic profile is provided. During operation, the system can determine a first traffic profile indicating whether to drop a packet based on the utilization of a queue. The packets from the queue can be forwarded via an egress port reachable via a fabric. The system can also determine a second traffic profile indicating whether to indicate congestion in the packet based on the utilization. The system can then determine a third traffic profile by combining the first and second traffic profiles. The third traffic profile can indicate acceptance at the queue for a subset of packets with a low-level congestion indicator or selected for dropping based on the utilization. Subsequently, the system can, if the packet is selected for dropping, determine whether to accept the packet at the queue with a high-level congestion indicator in the packet based on the third traffic profile.
