Investments in telecom service provider network functions virtualization (NFV) and software defined networking (SDN) are expected to grow at a compound annual growth rate of 94.3 percent until 2022 to over $168 billion according to a new report, released by research company Technology Business Research.
Of course, the range of companies involved is prodigious, including products sold by Cisco Systems, Citrix Systems, Dell Technologies, Hewlett Packard Enterprise, Huawei Technologies, Oracle, Nokia, Ericsson, Wind, Allot, Amdocs, Arista, Brocade, F5 Networks, Intel, Juniper, Metaswitch, NEC, Nakina Systems, ConteXtream, Cyan, Openwave, RAD, Opera, Mavenir, Netcracker and many others.
The report indicates that until now, the NFV and SDN market was driven by a small group of 20 to 25 tier-one operators. This group is expected to remain the key investor, with Tier two and tier three operators making their own investments at some point in the future.
NFV is seen by some researchers as encompassing much more than virtualization of communication networks, probably by including all software defined networking functions with network functions virtualization.
