“…The first approaches to the challenge previously described relied on Software Defined Networking (SDN)related technologies. In [4], the authors present their work on orchestrating an inter-domain L3-VPN by leveraging the OpenDaylight controller and several OpenFlow switches located in different domains. This work resulted in a prototype that enables the automatic setup and tear-down of VPNs by their end-users.…”

“…This work resulted in a prototype that enables the automatic setup and tear-down of VPNs by their end-users. To enable this, the authors of [4] developed an Agent responsible for processing the VPN creation requests from the end-users and interacting with the SDN controllers to provision the requested VPNs. The results achieved in [4] showcase that a VPN was created in no more than 10 seconds after the users requested it.…”

Inter-domain scenarios are immensely desirable in NFV since they allow network services to span across independent domains. However, providing a communication channel between the services' components in different domains is challenging, thus the need for mechanisms to simplify and automate this process. One possible approach to this problem is the employment of VPNaaS mechanisms. This work presents a zero-touch and NFV-based full-mesh VP-NaaS solution that can be used to establish a VPN mesh network encompassing different independent domains, thus enabling inter-communication between them. Furthermore, the VPN tunnels' orchestration is fully automated, being achieved without any human intervention.

“…The use of SDN and OpenFlow simplified the managment of the network, with works such as [14][15] [16] using OpenFlow to create a multi-domain and multipoint-to-multipoint VPN on-demand service (more specifically, VPLS). However, the VPNs stop at the edge of the network.…”

On-line access to information while on the move has conferred businesses with the capability to be constantly accessible and in operation, independently of geographical area or timezone. There are situations, however, that demand technical solutions for specific scenarios, such as controlled access to corporate-based content. Virtual Private Networks (VPNs) allow controlled remote access to content, supporting scenarios such as teleworking. Nonetheless, such mechanisms are not commonly associated with the highly mobile users of today, which can traverse different types of access networks, while still keeping access to content restricted to corporate network usage. In addition, as VPN mechanisms are disassociated from mobility procedures, service disruption can happen or specific mechanisms and clients can be required in end-user's equipment.This paper proposes a framework that leverages Network Slicing, enabled by Software Defined Networking and Network Function Virtualisation, to provide seamless and isolated access to corporate-based content, while moving through heterogeneous networks. This solution allows Mobile Network Operators to dynamically instantiate isolated network slices for corporate users, and handover them between 3GPP and non-3GPP networks while users move away from the corporate network. In this way, they are able to keep access to corporate-based content in a transparent way, while maintaining access requirements for the service being used. The framework was implemented and validated over an experimental testbed composed by mobile and Wi-Fi accesses, with results presenting improvements in terms of overhead signaling and data redirection without downtime nor stream reconnection.

“…In this work, they have used Openflow but not Netconf neither a set of YANG models; so this solution may not be something valid for a carrier-grade scenario. In [13] the work enables automatic setup and tear down of VPN instances via an easy to use web portal, without needing the help of network administrators to do the manual configuration of the network switches. In this work, a rest interface was exposed in the network controller to support all the OpenFlow configuration possibilities.…”

Current approaches to automate the design and configuration of transport services face several challenges. Firstly, there is a lack of open interfaces between the Operational Support Systems (OSS) and the network layer. The commercially available interfaces to Network Management Systems (NMSs) or directly to the devices are typically proprietary and with limited programmability. Secondly, for the case of IP/MPLS networks, the definition of how a service is built is particular to each operator.To solve this situation, this work presents an approach based on a hybrid SDN in which the definition of a VPN service is made with a modeling language and is not limited to a particular operator design nor a particular set of vendor devices. The IP/MPLS network topology and the VPN services are programmable via standard APIs with RESTCONF/YANG from an SDN Controller. This facilitates the operator on the one hand designing a new VPN service and its full automation. This work demonstrates, for the first time, that such automation is possible with proposed draft standards from IETF and validates its implementation, comparing the time consumed in the controller to process to different workflows from the same model.
