Abstract: A VNF controller (or module) instantiates two or more VNFs in a communication network to support a network service where the two or more VNFs include at least a first VNF and a second VNF. The VNF controller assigns a priority value to each VNF and monitors network resources allocated to each VNF. The VNF controller further determines the first VNF requires additional network resources and releases the network resources allocated to the second VNF based on respective priority values. The VNF controller further allocates the network resources released by the second VNF to the first VNF.

Abstract: A virtual network function (VNF) controller (or module) instantiates two or more VNFs in a communication network to support a network service where the two or more VNFs include at least a first VNF and a second VNF. The VNF controller assigns a priority value to each VNF base on an overall network impact, a physical location of at least one network resource allocated to the respective VNF, a type of service to be implemented by the respective VNF and a customer impact based on how many customers would be using the respective VNF. The VNF controller monitors network resources allocated to each VNF. The VNF controller further determines the first VNF requires additional network resources and releases the network resources allocated to the second VNF based on respective priority values. The VNF controller further allocates the network resources released by the second VNF to the first VNF.
