Network Virtualization Solutions

Fujitsu and Open Source Technology

Service providers and internet content providers require agile deployment of higher network functions, efficient and economical network upgrades, and drastic reductions in operating costs. Open source technology can help with all three requirements; industry watchers believe that the importance of open source will only grow.

Key Drivers of Open Source

There are two primary drivers of open source technology for service providers: software-defined networking (SDN) and network function virtualization (NFV.) There are more than twenty SDN/NFV private standardization groups and foundations.

Practical applications of these open-source projects include SDN control (ONOS and OpenDaylight), NFV/VNF management and orchestration, as well as Central Office Re-Architected as Datacenter (CORD) related initiatives that are more OSS/BSS centric. While SDN and NFV are all about network automation, the CORD concept provides a blueprint for using commodity access hardware with all the benefits of scale-out expandability in the datacenter. All of this requires multi-vendor connectivity and functional disaggregation of the transport network and is dependent on open APIs for software and hardware.

Another practical application of open source is the Open Compute Project that focuses on using standard data center hardware (server/rack/power module/switch/network) to capture power savings and increase knowledge sharing.

In addition to open source public projects, there are service providers and Web companies who are developing SDN/NFV solutions in house for their competitive advantage. For example:

  • Google (B4:SD-WAN, Andromeda: high-speed NFV, Jupitar: DCI, Espresso: SDN for dynamic peering point selection),
  • AWS (shifting to serverless computing by integrating micro-services)
  • AT&T (Network 3.0 Indigo: data-powered optimization)

To be competitive in the new digital business economy, service providers need to dedicate more budget and resources to service innovation. However, multi-layer/multi-vendor network design necessitates that a significant portion of any service provider's budget goes to the network itself. At Fujitsu, we are changing that: we are working with our customers to architect an entirely ‘open’ new system: disaggregated, flattened, and virtual.

Fujitsu joins more than 40 service providers and ICT vendors as a proud member of ONAP, an open source network service orchestration software. Fujitsu is also an ONOS board member and has been actively contributing to its northbound API designing/coding initiative. Finally, Fujitsu has participated in the residential CORD project of ON.Lab by providing first R-CORD POD, including an IA server, white box switch, OLT, and SDN controller.
