System architecture and deployment scenarios for SESAME: Small cEllS coodinAtion for Multi-tenancy and Edge services

Abstract

The surge of the Internet traffic with exabytes of data flowing over operators' mobile networks has created the need to rethink the paradigms behind the design of the mobile network architecture. The inadequacy of the 4G UMTS Long term Evolution (LTE) and even of its advanced version LTE-A is evident, considering that the traffic will be extremely heterogeneous in the near future and ranging from 4K resolution TV to machine-type communications. To keep up with these changes, academia, industries and EU institutions have now engaged in the quest for new 5G technology. In this paper we present the innovative system design, concepts and visions developed by the 5G PPP H2020 project SESAME (Small cEllS coordinAtion for Multi-tenancy and Edge services). The innovation of SESAME is manifold: i) combine the key 5G small cells with cloud technology, ii) promote and develop the concept of Small Cellsas-a-Service (SCaaS), iii) bring computing and storage power at the mobile network edge through the development of non-x86 ARM technology enabled micro-servers, and iv) address a large number of scenarios and use cases applying mobile edge computing.

Enhancing Network Management via NFV, MEC, Cloud Computing and Cognitive Features: The “5G ESSENCE” Modern Architectural Approach

“…combining the MEC and NFV concepts with SC virtualisation in 5G networks and enhancing them for supporting multi-tenancy [26]. The purpose of the Edge DC will be to provide Cloud services within the network infrastructure and also to facilitate by promoting and assisting the exploitation of network resource information.…”

The role of edge computing in future 5G mobile networks: concept and challenges

“…In this subsection we introduce the basic concept of CESC and Light Data Centre (Light DC). The design originates from the SESAME project [13].…”

Security requirements modelling for virtualized 5G small cell networks

“…Herein, we only describe the elements relevant to our security requirements modelling that will follow. More details on the SESAME architecture and the considered scenarios can be found in [8], [13].…”

“…A number of government and industry-funded R&D projects are working towards defining and developing 5G architectures, solutions, and technologies. For example, the EU-funded SESAME project [7], [8] targets innovations in the area of virtual small cells (VSCs) and the support of advanced services at the network edge by embracing the concept of mobile edge computing (MEC) [9]. The project also proposes a SDN/NFV-enabled architecture for MEC services in 5G SC networks.…”
