METHOD, SYSTEM, COMPUTER PROGRAM AND COMPUTER PROGRAM PRODUCT FOR MONITORING DATA PACKET FLOWS BETWEEN VIRTUAL MACHINES, VMS, WITHIN A DATA CENTRE

摘要

The following invention relates to methods, systems, computer programs and computer program products for supporting said method, and different embodiments thereof, for monitoring data packet flows between Virtual Machines, VMs, within a data centre. The method comprises collecting flow data for data packet flows between VMs in the data centre, and mapping the flow data of data packet flows between VMs onto data centre topology to establish flow costs for said data packet flows. The method further comprises calculating an aggregated flow cost for all the flows associated with a VM for each VM within the data centre, and determining whether to reschedule any VM, or not, based on the aggregated flow cost.

主权项

1. A method for monitoring data packet flows between at least a portion of Virtual Machines, VMs, within a data centre, said method comprises:
collecting flow data for data packet flows between the at least a portion of VMs in the data centre; mapping, based on the collected flow data, flow data of data packet flows between the at least a portion of VMs onto data centre topology to establish flow costs for said data packet flows; calculating, based on the established flow costs, an aggregated flow cost for all the flows associated with a VM for each of the at least a portion of VMs within the data centre; and determining whether to reschedule any of the at least a portion of VMs, or not, based on the aggregated flow cost.
