By 2028, 51.2 and 102.4 Tbps network chips are expected to enable the deployment of nearly 100M shipments of 800 Gbps and 1.6 Tbps switch ports in front-end networks. AI infrastructure build-outs, also known as “Back-End Networks”, have the potential to double these deployments.
“While Cloud Service Providers’ focus in the near term is on building AI back-end networks to support their AI infrastructure, we anticipate an accelerated pace of investments in front-end networks in the second half of our forecast horizon," said Sameh Boujelbene, Vice President at Dell’Oro Group. "Despite exponential growth opportunities in back-end networks, front-end networks are expected to continue driving the bulk of Ethernet data center switch sales over the next few years. Maintaining robust spending in front-end networks remains, therefore, essential to boosting the performance of major Ethernet switch suppliers.
“While back-end network will be the first to migrate to higher speed, we anticipate 51.2 Tbps-based switch deployment in front-end network to debut in 2024 and to enable a swift adoption of 800 Gbps. 102.4 Tbps-based switch deployments are expected to follow in 2025/2026 time frame and enable a second wave of 800 Gbps and the initial wave of 1.6 Tbps deployment,” added Boujelbene.
Additional highlights from the Ethernet Switch—Data Center 5-Year July 2024 Forecast Report:
Linear Drive Pluggable Optics (LPOs), an alternative to Co-Packaged Optics (CPOs), are expected to gain material traction during our forecast horizon.
SONiC (Software for Open Networking in the Cloud) adoption is expected to accelerate, achieving a 10-20 percent penetration rate in Tier 2/3 Cloud service providers and large enterprises by 2028.
