FACILITATING CONGESTION CONTROL IN A NETWORK SWITCH FABRIC BASED ON GROUP AND AGGREGATE TRAFFIC RATES |
摘要 |
A system for communicating packets through a network switch fabric is described. At an aggregation point in the network switch fabric, the system segregates packet flows from multiple sources into a set of quality-of-service (QoS) buckets. The system also associates packet flows from the multiple sources with a global QoS bucket. The system monitors traffic rates for each QoS bucket in the set of QoS buckets and the global QoS bucket. The system determines a state for each QoS bucket by comparing a traffic rate for the QoS bucket with state-specific thresholds. The system also determines a state for the global QoS bucket by comparing a traffic rate for the global QoS bucket with state-specific global thresholds. When a packet is received for a given QoS bucket, the system performs an action based on a state of the given QoS bucket and a state of the global QoS bucket. |

1. A method for communicating packets through a network switch fabric, comprising:
at an aggregation point in the network switch fabric, segregating packet flows from multiple sources into a set of quality-of-service (QoS) buckets; associating packet flows from the multiple sources with a global QoS bucket; monitoring traffic rates for each QoS bucket in the set of QoS buckets and the global QoS bucket; determining a state for each QoS bucket in the set of QoS buckets by comparing a traffic rate for the QoS bucket with one or more state-specific thresholds; determining a state for the global QoS bucket by comparing a traffic rate for the global QoS bucket with one or more state-specific global thresholds; and when a packet is received for a given QoS bucket, performing an action based on a state of the given QoS bucket and a state of the global QoS bucket. |
