Such an architecture enables combining centralized and distributed control with traditional VPN protocols to provision services through network slices. This paper presents the design and implementation of a Hybrid SDN-based network application to provide dynamic services. Software Defined Networking (SDN) appears as a solution to provide agile enterprise networking while reducing operators cost. VPNs are commonly based on static bandwidth allocation over MPLS tunnels, which cause over-provisioning and under-utilization of network resources. Internet Service Providers (ISPs) must therefore offer a reliable and cost-effective connectivity solution. Nowadays, companies strongly rely on Virtual Private Networks (VPNs) to deliver services between geographically distributed branch offices. The system simplifies the process to create both simple and complex environments, run simulations, and collect measurement data. The platform combines network virtualization technologies with virtual machines (VMs) running open-source and commercial operating systems VM orchestration capabilities a context-aware configuration engine and an extensible data-collection framework. This demonstration will show VIRL - the Virtual Internet Routing Lab - a platform that can be used for network change validation, training, education, research, or network-aware applications development. Testing and verifying at scale is a challenge: network equipment is expensive, requires space, power and cooling, and there is never enough test equipment for everyone who wants to use it! Network virtualization technologies enable a flexible environment for educators, researchers, and operators to create functional models of current, planned, or theoretical networks. The increasing demand to provide new network services in a timely and efficient manner is driving the need to design, test and deploy networks quickly and consistently.
