One aspect of the instant application provides a system and method for generating internal traffic for a switch. During operation, the system configures a replication list comprising a plurality of replication entries, with a respective replication entry corresponding to a destination port on the switch. The system generates a seed packet to be replicated for each replication entry in the replication list, with a destination address of a respective replicated packet corresponding to a replication entry. All replicated packets are associated with a virtual local-area network (VLAN) reserved for the internal traffic. The system then forwards the replicated packets along with external packets received by the switch to corresponding destination ports on the switch.

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.

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.

In some examples, a system populates a distribution data structure useable by a switch in distributing communications of data packets across a plurality of network paths for the switch. In response to an addition of a new network path or a removal of an existing network path for the switch, the system updates entries of the distribution data structure using a process that identifies selected entries of the distribution data structure to skip as part of updating the distribution data structure.
