The ICCLab T-Nova members are back from the 3rd and final project review meeting that was held\u00a0on March 16th in Athens, Greece. Couple of days before that, we were enrolled in the preparation and setup of the final demos at N.C.S.R. Demokritos<\/a> premises.<\/p>\n

Several demonstrations were shown to the reviewers during the demo session in order to point out the achievements in the last year of the project. Moreover a poster session was held in parallel to stress the contributions in terms of conference and journal papers published within the project’s scope, Figure 1.<\/p>\n

The involvement of the ZHAW team in the final year’s progress was related to the billing and charging model in the T-Nova Marketplace, and the Service Function Chaining support for the end-to-end multi-PoP scenario by using Netfloc<\/a> – the T-Nova SDK4SDN.<\/p>\n

Figure 2 shows the Demo3 scenario and its related components. Shortly, the demo idea is the following: A customer buys a Network Service (NS) composed by several VNFs, which has been created by the Service Provider through a Network Service Descriptor (NSD)<\/a> at the T-NOVA Marketplace<\/a>; Tenor<\/a>, the T-Nova orchestrator, takes over resource provisioning and service deployment; Netfloc<\/a>‘s Create Chain API is invoked by Tenor and Netfloc establishes the SFC VNFFGD in the network; WICM<\/a>\u00a0(the T-Nova Connectivity Manager) handles the redirection of customer’s traffic to the NFVI-PoPs transparently, as well as the inter-PoP traffic connection.<\/p>\n

Some of the achievements shown include the top-down integration Marketplace-Tenor-Netfloc that was demonstrated in two phases: the first part involved the interaction of the Customer with the Marketplace including: service purchase, billing model selection, VNFs composition and finally – PoP election for the service deployment – in this case, Athens and Aveiro datacenters. This part is shown with the video footage on Figure 3.<\/p>\n
