- Global data center and enterprise LAN software-defined networking (SDN) market revenue—including SDN-in-use bare metal and branded Ethernet switches and SDN controllers—is anticipated to reach $15.8 billion by 2022.
- Bare metal switch revenue came to $790 million in 2017, representing 26 percent of total in-use SDN-capable Ethernet switch revenue.
- Data center SDN controller revenue totaled $1.2 billion in 2017, and is expected to hit $4 billion by 2022, when it will represent 17 percent of data center and enterprise LAN SDN revenue.
- Cisco is number-one with 21 percent of 2017 in-use SDN revenue, VMware comes in at number-two with 19 percent, Arista at number-three with 15 percent, White Box at number-four with 12 percent and Huawei at number-five with 7 percent.
The data center and enterprise LAN market is maturing. In-use SDN revenue totaled $4.4 billion worldwide in 2017, and is expected to hit $15.8 billion by 2022. Innovations continue, with bare metal switch vendors announcing 400GE switches with new programmable silicon that incorporates an on-chip ARM processor to support artificial intelligence (AI) and machine learning (ML) and allows data plane protocols to be modified without changing silicon. Also of note, Edgecore Networks contributed its 440GE switch design to the Open Compute Project (OCP).
SDN controllers for the data center also continue to add functionality, with increased support for interconnecting multiple on-premises data centers, and with support for interoperation between cloud service provider (CSP) data centers and enterprises as they build multi-clouds. Other notable enhancements include features that support container networking and integration with container management software such as Kubernetes.
Data center and enterprise LAN SDN is now mainstream and the market is expected to grow.
“Not all the $15.8 billion in revenue in 2022 is new. SDN-capable Ethernet switch revenue is existing revenue, and a portion of SDN controller revenue is displaced from the Ethernet switch market due to reduced port ASPs,” said Cliff Grossner, Ph.D., senior research director, IHS Markit. “Some network operators will elect to use bare metal Ethernet switches when deploying SDNs and rely on SDN controllers for advanced control plane features.”
