Abstract
Various methods and systems are provided for oversubscription buffer management. In one embodiment, among others, a method for oversubscription control determines a utilization level of an oversubscription buffer that is common to a plurality of ingress ports and initiates adjustment of an ingress packet rate of the oversubscription buffer in response to the utilization level. In another embodiment, a method determines an occupancy level of a virtual oversubscription buffer associated with an oversubscription buffer and initiates adjustment of an ingress packet rate in response to the occupancy level. In another embodiment, a rack switch includes an oversubscription buffer configured to receive packets from a plurality of ingress ports and provide the received packets for processing by the rack switch and a packet flow control configured to monitor an occupancy level of the oversubscription buffer and to initiate adjustment of an ingress packet rate in response to the occupancy level.
