Service Negotiation in Application-Centric Networks Leveraging ONOS Framework

Each application is characterized by a multitude of requirements, such as bandwidth, latency, encryption, etc., defining the type of connectivity Service Request (SR) that the network should satisfy. The application-centric networking paradigm proposes a novel provisioning process to take into account such application-specific requirements. ONOS offers a northbound interface used to specify a few application requirements, called intent-based interface, and is able to evaluate the SRs based on the current network state and to provision paths according to application requirements. If a path with the given requirements cannot be found on the shortest path, the SR is blocked. In this talk we demonstrate a first implementation of a resource negotiation scheme between users and a network for the provisioning of application-aware connectivity services to reduce the blocking of SR when the network does not have enough resources to satisfy the original SR. The work has been carried out within the ACINO European Project. We enriched ONOS with an abstracted human-readable provisioning interface, called DISMI that allow the high-level definition of SRs (e.g., set of connection point abstracted as a datacenter or a city). Moreover, a GUI client is provided to the users for interacting with DISMI via an HTTP RESTful API. The most significant extension has been developed within the ONOS Intent Framework to provide an advanced application-aware mechanism that leverages the ONOS Resource Manager to trigger the negotiation process in case of insufficient network resources. The negotiation proposes a set of alternative solutions that offer a degradation/upgradation of the initial service requirements, so that the user, who issues the initial SR, may choose interactively a solution that can be provisioned in the network.
