摘要： A data segment of a data packet destined for an egress port of an egress node may be received at a first ingress node. An egress statement vector and an ingress statement vector may be identified at the first ingress node. A determination may be made, based on the egress statement vector and ingress statement vector, whether the first ingress node is authorized to transfer the data segment to the egress port before the other data segments of the data packet are received at the first ingress node. The data segment may be transferred to the egress port before the other data segments of the data packet are received at the first ingress node when the determination indicates the first ingress node is authorized. The data segment may be stored in a buffer of the first ingress node when the determination indicates the first ingress node is not authorized.

The data packet is associated with a packet priority level. The ingress node is configured to receive an egress statement vector from the egress node indicating whether the egress port is or is not flow controlled for data associated with the packet priority level. The ingress node is configured to determine whether the egress port is available to receive the data segment from the ingress node before other data segments of the data packet are received at the ingress node based on the egress statement vector.

摘要： A system and method for achieving lossless packet delivery in packet rate oversubscribed systems. Link-level packet rate control can be effected through the transmission of packet rate control messages to link partners of an oversubscribed system. The transmission of packet rate control messages can be triggered upon a determination that a packet arrival rate over a set of ingress ports exceeds a packet processing rate of a packet processing unit bound to the set of ingress ports. In one embodiment, the packet processing rate is artificially reduced due to a reduction in power consumption in the oversubscribed system.
