“…The possibility of using software defined technologies to realize future networks has received broad attention from both industry [11,12,41,7] and academia [54,27,45,35,33]. Various industry players are collaborating on "re-architecting central offices as data centers" [41].…”

We present Proteus, a mobile network service control platform to enable safe and rapid evolution of services in a mobile software defined infrastructure (SDI). Proteus allows for network service and network component functionality to be specified in templates. These templates are used by the Proteus orchestrator to realize and modify service instances based on the specifics of a service creation request and the availability of resources in the mobile SDI and allows for service specific policies to be implemented. We evaluate our Proteus prototype in a realistic mobile networking testbed illustrating its ability to support service evolution.

“…In that model, the NVF platform is hosted by the ISP and forms a marketplace (see also the work in the context of the T-NOVA [7], [8] EU-funded FP7 project) where CDN operators can upload VNFs, which can in turn be chained by the ISP into different types of CDN services and under different pricing options. Business-wise, our approach is more on the telco CDN side, and, thus, more ISP-centric: The network provider fully controls both the NFV/cloud platform and the content delivery service.…”

Abstract-We present the design and implementation of a Content-Delivery-Network-as-a-Service (CDNaaS) architecture, which allows a telecom operator to open up its cloud infrastructure for content providers to deploy virtual CDN instances on demand, at regions where the operator has presence. Using northbound REST APIs, content providers can express performance requirements and demand specifications, which are translated to an appropriate service placement on the underlying cloud substrate. Our architecture is extensible, supporting various different CDN flavors, and, in turn, different schemes for cloud resource allocation and management. In order to decide on the latter in an optimal manner from an infrastructure cost and a service quality perspective, knowledge of the performance capabilities of the underlying technologies and compute resources is critical. Therefore, to gain insight which can be applied to the design of such mechanisms, but also with further implications on service pricing and SLA design, we carry out a measurement campaign to evaluate the capabilities of key enabling technologies for CDNaaS provision. In particular, we focus on virtualization and containerization technologies for implementing virtual CDN functions to deliver a generic HTTP service, as well as an HTTP video streaming one, empirically capturing the relationship between performance and service workload, both from a system operator and a user-centric viewpoint.Index Terms-Content delivery networks, experimental approaches, cloud computing, network functions virtualization, network planning and service deployment, quality of experience, virtualization.

“…Even though many NFV platforms that support the quick deployment of new network services already exist today [2], [6]- [9], concepts, workflows, and tools to create and automatically test such services are still very limited or completely missing and need to be established to fully support the DevOps methodology for NFV. Some initial approaches for this have been presented by the SONATA [8] project, which provides a set of SDK tools that support service developers to create and ship new network services.…”

Abstract-5G does not only aim at higher capacity and lower latency than current 4G in mobile broadband networks, but also to increase the level of programmability, control and flexibility to meet the requirements from innovative use cases such as IoT, smart manufacturing, and immersive media. However, several difficulties still need to be overcome for a better technological adoption. To reduce the time-to-market for networked services and to lower the entry barrier to third party developers of VNFs and network services, an integrated development and operations (DevOps) methodology is a promising way. One of the biggest challenges in upcoming 5G DevOps is the validation and verification (V&V) of individual VNFs and network services (VNF graphs) so that operators can be sure of their behavior. In this paper, we propose an NFV architecture that supports the DevOps methodology with a V&V platform and an advanced NFV catalogue. The conceptual components of the V&V platform, the foreseen methodology and the outcomes are explained. Finally, we explore some perspectives in applying such V&V approach in another 5G research project.
