Principal goal: Federating Japanese and European 5G Testbeds to Explore Relevant Standards and Align Views on 5G Mobile Network Infrastructure Supporting Dynamic Creation and Management of Network Slices for Different Mobile Services. サービスに応じたスライス動的生成・管理機能の実証と標準化を目的とする日欧連携5G移動通信基盤テストベッド
5G!Pagoda represents the next evolution step in softwarized networks as supported by NFV, SDN and aimed at by the 5G network evolution. The top objectives of 5G!Pagoda are Transport and Risk Management for critical issues such as Climate Action and Secure Societies.
i) the development of a scalable 5G slicing architecture towards supporting specialized network slices composed on multi-vendor network functions, through the development of
of ii) a scalable network slice management and orchestration framework for distributed, edge dominated network infrastructures, and convergent software functionality for
iii) lightweight control plane and
iv) data plane programmability and their integration, customization, composition and run-time management towards different markets in Europe and Japan.
5G!Pagoda will develop a coherent architecture enabling research and standardization coordination between Europe and Japan. The proposed developments integrate with a common SDN/NFV based architecture and will additionally provide punctual and highly important developments of the software network architecture. The developments address the next steps of the evolution beyond the immediate NFV standardization and developments, enabling the graceful integration within end-to-end network slices of various highly customized software components, remotely controlling the data path, with specific network function flexibility and network function placement support and easy to manage through a convergent set of scalable orchestration APIs.
Besides the technological aspects, 5G!Pagoda will develop a coherent proof of concept with two playground nodes, one in Japan and one in Europe, using a uniform network orchestration and a set of in-slice software features enabling the transparent exchange of knowledge and practical implemented components for dynamic deployment and execution of virtual network functions and applications. The testbed will allow practical demonstration of the functionality and will enable the development of an aligned 5G-oriented standardization roadmap for Japan and Europe.
Objective 1: Develop a scalable 5G slicing architecture, extending the current NFV architecture towards support of different specialized network slices composed of multi-vendor virtualized network functions, taking into account interoperability within/among the network slices as well as with legacy system-based services.
Objective 2: Devise a scalable network slice management and orchestration mechanism enabling the efficient deployment of end-to-end services across a mobile edge dominated architecture.
Objective 3: Develop a convergent slice supporting mechanism including the interaction with and the chaining of the specific network functions, deciding what network functions to select for various services with heterogeneous requirements, where to place the network functions, and where to run them.
Objective 4: Develop a high programmable network control and data path supporting mechanism, along with logically centralized control state management and highly distributed software-defined data plane functionalities.
Objective 5: Develop a coherent proof of concept with two testbeds, namely one in Europe and another in Japan, using a uniform network orchestration and a set of slice-support mechanisms enabling the easy exchange of knowledge on service deployments and the dynamic deployment of virtual network functions and applications.
Objective 6: Develop use cases on IoT and human communication for representing emerging 5G applications and services that require high scalability and customization of diverse end-user requirements.
Objective 7: Develop global consensus on the 5G!Pagoda architecture and interfaces through documented contributions to 5G standardizations (e.g., 3GPP, IMT-2020, and ETSI NFV) and open source projects (e.g., OPNFV), and through participation in influential fora in Europe and Japan to disseminate the results of the 5G!Pagoda proof of concept to be developed as per Objective 5.
Objective 8: Establish long-term research collaboration between leading industry players, top research institutes and universities in Europe and Japan, i) to align views on 5G network architecture, ii) to prevent further fragmentation in 5G research, iii) to jointly create research results in terms of deliverables, scientific publications and intellectual properties, iv) to join efforts towards achieving Objective 7, and v) to ultimately help Europe and Japan retain the competitive edge in the field of mobile communication systems.
