Fujitsu and the Rise of Next-Generation Networks: A Technical Deep Dive

Executive Summary

The digital transformation wave driven by the fusion of network and cloud computing infrastructure, IoT maturity, and the expansion of 5G requires a resilient, reliable, and affordable network. This white paper explores the key technologies and products on the Fujitsu Next Generation Network, designed to enable this digital transformation.

Technical Background

The Next Generation Network includes three groups – business-oriented networks, virtual resource and network functions, and physical networks. These groups are combined, rationalized, and reconciled seamlessly to establish a closed network that meets industry-specific requirements, support automation, orchestration, optimization, and provide end-to-end service provisioning.

System Architecture

Fujitsu’s Next Generation Network architecture is based on the consolidation of Business-oriented Networks, Virtual Resource and Network Functions, and Physical Networks. The architecture is designed to be highly scalable, with open and standardized control plane interfaces that support multi-vendor hardware interoperability.

Implementation Details

The implementation of a business-oriented network depends on the industry’s unique requirements. For instance, the manufacturing sector requires reliability and simultaneous connection capacity, while the healthcare sector relies on broad bandwidth and tolerance. Network functions, servers, and edge compute resources are virtualized to support automation, orchestration, and optimization. High scalability is a must-have feature for the physical network layer.

Code Examples

While this whitepaper does not provide specific code examples, the implementation of network functions and resource virtualization, orchestration, and optimization in the Fujitsu Next Generation Network involves multiple layers of software engineering, including high-level programming, scripting languages, and system administration.

Performance Analysis

Fujitsu’s Next Generation Network is designed to handle the massive data flow requirements of the digital transformation era. It delivers superior performance by blending physical networks, virtual resources, and business-oriented networks into a harmonized infrastructure.

Security Considerations

In every sector, security is paramount. The network’s design must account for unique security requirements, such as scalability and geographical coverage in the retailing sector, and broad bandwidth and tolerance in the healthcare sector.

Troubleshooting

Fujitsu’s Next Generation Network is designed for high reliability, but in case of issues, the design enables closed-loop feedback and analysis using artificial intelligence for appropriate action and remediation.

Conclusion

As digital transformation continues to evolve, Fujitsu’s Next Generation Network provides a robust and flexible foundation for delivering individualized services on-demand. The network’s design takes into consideration the unique requirements of different sectors, offering a solution that is scalable, secure, and reliable.
