SDN Enabled Network: What Does It Take?
It is no surprise that increasing bandwidth demands, changing traffic patterns driven by the migration of applications and workloads to the cloud, and competitive pricing pressures are driving service providers toward cost-optimized, disaggregated, programmable optical infrastructure, which are now delivering multi-terabit transmission over a single fiber pair via 100G, 200G, 400G and most recently 600G wavelengths with advanced coherent dense wave division multiplexing technology. Even though these transmission speeds are impressive, new technologies such as 5G mobile services, augmented/virtual reality and on-demand 4k streaming video mean that bandwidth demand pressure will only increase. IP traffic is expected to grow at 26% CAGR through 2022. Global cloud IP traffic is increasing even faster at 27% CAGR through 2021.
At the same time that they are addressing bandwidth requirements, service providers are also working to reduce their operational costs and manual activities by adopting software-defined networking (SDN). With SDN, network elements and functions are abstracted utilizing data models and open, programmatic interfaces. Combined with real-time data collection, performance monitoring and intelligent analytics, SDN can simplify network operations and enable closed-loop automation.
Providers are turning to vendors to provide intelligent, automated, multi-layer, multi-domain, multi-vendor control and automation. However, they are not just turning over the reins of development to their vendors. CSPs are actively participating in collaborative co-creation processes with their vendors.
Where does Fujitsu fit in this new paradigm?
Read how the changes at Fujitsu are far more extensive than the delivery of an SDN controller. Fujitsu is adopting disaggregated, programmatic infrastructure as evident in its 1FINITY™ platform. Fujitsu is adopting containerized microservices and microapplications for delivering custom solutions and automation without impacting other parts of the network or the solution. The company is also utilizing Agile development processes with co-creation to offer CSPs the opportunity to become collaborators in the innovation process. This combination adds up to a company on a mission to transform itself and its customers’ networks.
