“…After the service chaining, the second challenge is to find the best placement for the VNFs, considering: 1) available resources, 2) requirements of the requested NS, and 3) possible impact on the other running NSs. These challenges can be modeled whereby NP-hard optimization problems, such as Location-Routing Problems (LRP) [39] and Virtual Network Embedding (VNE) [40]. The solution to this problem will be passed to the embedded SDN controller in the VIM to instantiate the NS.…”

This paper analyzes current standardization situation of 5G and the role network softwarization plays in order to address the challenges the new generation of mobile networks must face. This paper surveys recent documentation from the main stakeholders to pick out the use cases, scenarios and emerging vertical sectors that will be enabled by 5G technologies, and to identify future high-level service requirements. Driven by those service requirements 5G systems will support diverse radio access technology scenarios, meet end-to-end user experienced requirements and provide capability of flexible network deployment and efficient operations. Then, based on the identified requirements, the paper overviews the main 5G technology trends and design principles to address them. In particular, the paper emphasizes the role played by three main technologies, namely SDN, NFV and MEC, and analyzes the main open issues of these technologies in relation to 5G.

Abstract-Next generation networks and applications have recently drawn the attention of many researchers in both academia and industry. The plethora of service orchestration, embedding and scheduling solutions being developed indicates that efficient resource utilization in the cloud and edge/fog architecture is of crucial importance in order to exploit the great economic potential of this infrastructure. In this paper we propose a novel service orchestration approach that aims for speed and quality in terms of service provisioning: our embedding algorithm instantly deploys end-to-end delay-constrained service graphs while regularly offloads the most burdened parts of the infrastructure applying a cost-aware VNF migration strategy. In this sense we propose a hybrid orchestration approach, which unites the advantages of online heuristic and offline optimizing service orchestration methods, with the goal of obtaining a system design that provides fast service placement decisions and efficient long-term operation. By an exhaustive evaluation of our orchestration system on core, cloud and edge network topologies, we show its benefits in efficiency and the collateral cost of migrations.

“…Algorithms for VNE vary according to how they perform the mapping; link and node mapping can be performed separately, as in [40], [39], [27], or in a joint manner as in [8], [7]. Approaches also vary according to their embedding objectives, and optimization strategies used; recent surveys of VNE can be found in [12], [11].…”
