A flurry of development can be observed from open source communities, such as OPNFV and ONAP, as well as from individual efforts by telcos.
"Japan leads in the region, not only because of the desire to design resilient and reliable networks in preparation for future disaster threats, but also to prepare for the 2020 Summer Olympics," said Lian Jye Su, Senior Analyst at ABI Research. "South Korea and China are actively preparing for 5G, which requires both cloud radio access networks (C-RAN) and Cloud Core Networks. At the same time, the rest of the regions are actively catching up. Tier Two telcos, like Banglalink and Ncell, are currently deploying virtual subscriber data management platforms."
The industry has long agreed that there is no single approach to NFV and the latest market developments demonstrate just that. In July 2017, SK Telecom launched T-MANO, its own network function virtualization management and orchestration (MANO) platform. This move is contrary to major Chinese telcos, who opt to collaborate with large number of vendors and other telcos in ONAP to develop a common MANO platform. Telcos in China aim to become the catalyst for the government "Made in China 2025" strategy. Through their NFV initiatives, Chinese telcos can empower local industrial players with new capabilities, such as multi-access edge computing, massive machine type communications, dynamic cloud services and vehicle-to-everything communications.
"That is why the recent NFV interoperability test between Cisco, Ericsson, Huawei, and Nokia are important. Such collaboration allows telcos to truly embrace the multi-vendor NFV deployment and benefit from the open source nature of NFV," concludes Su. "We believe that virtualized network function onboarding, interoperability testing, and lifecycle management are becoming the new focus of the industry, as telcos seek to leverage the strengths of different hardware and software vendors."
