“…One of the biggest challenges in upcoming 5G DevOps environments [3] is the validation and verification (V&V) of virtual network functions (VNFs) and network services (NSs) against different execution platforms so that service operators can be sure that VNFs and NSs behave as expected immediately after they are deployed and put into production. Such a V&V process not only includes functional testing of VNFs and NSs but also non-functional tests, such as performance measurements for gaining insights about resource requirements to fulfil service level agreements (SLAs) and to provide the expected quality of experience (QoE) [5].…”

“…Despite the expected benefits of SDN/NFV technologies, several adoption difficulties need to be overcome. Some significant difficulties are the need for interoperability between VNFs and orchestrators (which is being reduced through the open source software community, with efforts such as OSM [2] or SONATA [3]), the combination of SDN and NFV technologies (e.g. lack of flexible support for end-to-end multi-site installations), and the consolidation of the initiatives (to avoid the "additional development needed").…”

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.

“…Examples include tests of configuration mechanisms as well as the validation of scaling and placement decisions and their effects on the network service. However, these validation tasks become very complicated and resource consuming, even if they could be automated in a DevOps pipeline [5], because testbed installations for each PoP and its attached virtualization infrastructure are required.…”

Abstract-Developing a virtualized network service does not only involve the implementation and configuration of the network functions it is composed of but also its integration and test with management solutions that will control the service in its production environment. These integration tasks require testbeds that offer the needed network function virtualization infrastructure (NFVI), like OpenStack, introducing a lot of management and maintenance overheads. Such testbed setups become even more complicated when the multi point-of-presence (PoP) case, with multiple infrastructure installations, is considered.In this demo, we showcase an emulation platform that executes containerized network services in user-defined multi-PoP topologies. The platform does not only allow network service developers to locally test their services but also to connect realworld management and orchestration solutions to the emulated PoPs. During our interactive demonstration we focus on the integration between the emulated infrastructure and state-of-theart orchestration solutions like SONATA or OSM.

“…It aims to make the service platforms easier and modular to be suitable for the requirements of the different service providers. Also, it stands with the network function orchestration and provides a development model for the developers [9]. MANO is an open source project that was developed by European Telecommunications Standards Institute (ETSI) [10].…”

Abstract:One of the main design aspects of the Tactile Internet system is the 1 ms end-to-end latency, which is considered as being the main challenge with the system realization. Forced by recent development and capabilities of the fifth generation (5G) cellular system, the Tactile Internet will become a real. One way to overcome the 1 ms latency is to employ a centralized controller in the core of the network with a global knowledge of the system, together with the concept of network function virtualization (NFV). This is the idea behind the software defined networking (SDN). This paper introduces a Tactile Internet system structure, which employs SDN in the core of the cellular network and mobile edge computing (MEC) in multi-levels. The work is mainly concerned with the structure of the core network. The system is simulated over a reliable environment and introduces a round trip latency of orders of 1 ms. This can be interpreted by the reduction of intermediate nodes that are involved in the communication process.
