System and methods for load placement in data centers

摘要

A system for operating information handling systems forming a network including a plurality of switches is provided. The system includes an open flow controller coupled to each of the plurality of switches; a plurality of links, each link configured to transmit data packets between two switches from the plurality of switches; wherein: the open flow controller is configured to determine a traffic flow across each of the plurality of links; and each one of the plurality of switches is configured to re-route a data packet when the traffic flow in a link associated to the switch exceeds a threshold. A computer program product including a non-transitory computer readable medium having computer readable and executable code for instructing a processor in a management unit for a plurality of information handling systems as above is also provided. A network managing device coupled to a service provider having resources is also provided.

1. A system for operating a plurality of switches forming a network, the system comprising:
an open flow controller coupled to the switches; wherein the open flow controller is configured to:
receive a notification of a start of a flow;determine traffic rates on a first link connecting a first switch and a second switch in the network; andin response to determining that the traffic rates on the first link exceed a threshold:
send a command to a forwarding top of rack switch to perform a push label operation on first network traffic in the flow so that the first network traffic is re-routed away from the first link;send a command to the first and second switches to perform a swap label operation on second network traffic to re-route the second network traffic away from the first link; andsend a command to a receiving top of rack switch to perform a pop label operation on the first network traffic.
