Systems and methods for allocating resources by a network device
View Patent ↗Systems and techniques to set a new service rate for one or more queues of a router and a new power consumption level for a router is disclosed. The queues are configured to store data packets awaiting transmission from the router. The setting of the new service rate or rates and new power level is based on a service rate of the one or more queues and a power consumption level of the router. The techniques disclosed further include resetting a new service rate for the one or more queues of the router and a new power consumption level of the router. The resetting of the new service rate or rates and new power level is based on a service rate of the one or more queues and a power consumption level of the router. The setting and resetting steps are based differently on the power consumption level of the router.
1. A method, comprising:
setting a new network traffic service rate to be provided for traffic passing into and out of one or more queues of a router and a new power consumption level for the router, said one or more queues being configured to store data packets awaiting transmission from the router, the step of setting being based on a service rate of the one or more queues and a power consumption level of the router; and
resetting a new network traffic service rate for traffic passing into and out of the one or more queues of the router and a new power consumption level of the router, the step of resetting being based on a service rate of the one or more queues and a power consumption level of the router; and
wherein the step of setting and the step of resetting are based differently on the power consumption level of the router; and
wherein the step of setting and the step of resetting are based on an instantaneous power usage rate in said router; and
wherein the step of setting includes selecting a vector from a set, the vector defining a service rate for the one or more queues of the router and a power consumption level of the router.
2. The method of claim 1 , wherein the selecting step includes comparing values of an expression for different ones of the vectors of the set.
3. The method of claim 2 , wherein the step of resetting includes selecting another vector from the set, the selecting another vector including comparing values of an expression for different ones of the vectors of the set.
4. The method of claim 2 , wherein the expression depends linearly on the service rate for each queue of the router.
5. The method of claim 1 , further comprising:
receiving at the router a value of a length of a queue in a network node, the network node being configured to store data packets received from the router in the queue in the network node.
6. The method of claim 5 , wherein both the step of setting and the step of resetting are based in part on the length.
