Abstract

A method and system is disclosed for provisioning of resources in a virtualized carrier network environment. The method and system includes collecting metrics about the virtualized carrier network environment. The collected metrics are provided to a forecasting module to generate future network traffic volume. Based on the forecasted network traffic volume, a decision to scale up or down a capacity of a virtual network appliance is taken.

Method and System for Provisioning of Resources in a Virtualized Carrier Network Environment

In the telecommunication industry there is a major trend for network operators to move toward a new paradigm called Network Function Virtualization (NFV). Under this paradigm core network appliances that are traditionally in the form factor of closed hardware boxes can be run as software appliances in virtual machines on generic computer platforms such as servers, blades, clusters, datacenter, etc. One of the main advantages of this approach is that as network operators are able to observe network traffic volume and can scale capacity of a network appliance accordingly . Currently, there are two main approaches in NFV that are being taken . The first approach is to report network traffic changes to a network administrator, who then provisions more capacity to the appliance by adding new VMs (or remove VMs if traffic has decreased) or change configuration of the VM. The second approach is to employ a monitoring element to detect changes in network traffic or VM resource utilization and automatically trigger addition or deletion of VM resources. The current approaches incur substantial delay to prepare, deploy, and configure VMs. In an enterprise data center space, there are methods that have been proposed to use a trend analysis technique to provision VMs and applications in advance based on the measured

workloads or resource utilization of currently deployed VMs. However, they do not have a component to estimate end-to-end network performance or integrate with network management system, operations support system when making the proactive decision .

Disclosed is a method or system for provisioning of resources in a virtualized carrier network environment. The method and system includes collecting metrics about the virtualized carrier network environment. The collected metrics are provided to a forecasting module to generate future network traffic volume . Based on the forecasted network traffic volume, a decision to scale up or down a capacity of a virtual network appliance is taken.

In accordance with the method and system, one or more metrics regarding the virtualized carrier network environment is collected. The one or more metrics include one or more of, but not limited to, network status, user experience, input from management system such as a Network Management System (NMS), Operations Support System (OSS), Business Support System (BSS), a physical server and a virtual network appliance such as, CPU, memory, I/O readings from the virtual network appliance.

The system includes a monitoring component, a predictive analysis component, a scaling decision module, an appliance management system and a virtual network appliance as illustrated in Fig. 1.
