SYSTEM USED BY CDN COMPANIES TO IMPROVE THE QUALITY OFFERED TO THE USERS AND TO OPTIMIZE RESOURCE UTILIZATION

摘要

The invention relates to the system used by CDN companies to 5 improve the quality offered to the users and to optimize resource utilization characterized as containing the following process steps: the workload automation engine (60) should be listening the instance manager (70) (S2001), the Instance Manager (70) sends the source information of the physical machine (30) to the Workload Automation Engine (60) at the 10 end of the period (S2002), number of incoming requests are sent by the load balancer (50) to the workload automation engine (60) based on the request type (S2003), the VNF (40) distribution is created by the workload automation (60) according to the new algorithm (S2004), checking whether the newly generated VNF (40) distribution is different from the 15 previous period distribution (S2005), the new VNF (40) distribution is sent by the workload automation engine (60) to the instance managers (70) (S2006), the processes to be performed with respect to each of the CDN nodes (41, 42, 43) in their own physical machines (30) are compared by from the instance managers (70) according to the decision received from 20 the workload automation engine (60) (S2007) and observations of the requests up to the end of another period and the monitoring of the source states of the physical machines (30) (S2008).
