Fujitsu & the Evolution of Next-Generation Networks

Executive Summary

In the evolving digital landscape, network value is centered around the exchange of meaningful information. Fujitsu is at the forefront of this transformation, building the next generation networks that can handle the rapid growth of cloud applications and IoT devices. These networks combine physical, business-oriented, and virtual resources to establish resilient, reliable, and affordable infrastructures that capitalize on artificial intelligence.

Technical Background

Historically, the value of transport networks was confined to the transference of bits of data between network elements. The emergence and sophistication of cloud technology have opened up new opportunities, connecting new devices, servers, and applications beyond simple transport. Fujitsu is leading this transition, envisioning a network where IT and CT merge into a harmonized macrocosm that delivers individualized services on-demand.

System Architecture

Next-generation networks comprise three distinct groups: business-oriented networks, virtual resources and network functions, and physical networks. Each has unique requirements and characteristics that need to be seamlessly integrated to realize the full potential of next-generation networks.

Implementation Details

These networks are designed to meet the specific requirements of different sectors. For instance, the manufacturing sector needs reliability and high simultaneous connection capacity, while healthcare depends on wide bandwidth. Virtualization of network functions, servers, and edge compute resources enable automation, orchestration, and optimization of these networks. The physical network layer, which provides end-to-end service provisioning, requires high scalability, standardized control plane interfaces, and a functionally disaggregated architecture for on-demand hardware additions.

Code Examples

While this document does not include specific code examples, it underlines the need for standardized control plane interfaces and a disaggregated architecture that supports multi-vendor hardware interoperability. This enables seamless integration of various network elements and aids in the optimization of resource allocation.

Performance Analysis

The performance of Fujitsu’s next-generation networks is contingent on their ability to adapt to rapidly evolving technological trends. Their resilient design can facilitate the hand-off of information between multiple end points, making them ideal for IoT applications and 5G adoption.

Security Considerations

Security is of paramount importance in the design of next-generation networks. This includes ensuring that the network is capable of establishing closed networks that meet the requirements of their respective industries, and implementing tight security measures for public, private, and on-premise clouds.

Troubleshooting

When challenges arise, closed-loop feedback and analysis using AI can take appropriate remedial action. This is facilitated by the virtualization of network resources, which supports automation and orchestration of the network.

Conclusion

Fujitsu’s vision for next-generation networks is one of unity – a digital transformation where IT and CT unite in a harmonized macrocosm. With a focus on resilience, reliability, and affordability, these networks are poised to redefine the ways in which we connect and communicate.
