IDC Finds Growth in the Ethernet Switch Market and Slight Decline in the Router Market in Q2 2021

Ethernet Switch Market Increased 10.8% Year Over Year; Router Market Declined 0.5% in 2Q21

NEEDHAM, Mass.–(BUSINESS WIRE)–#EthernetSwitch–The worldwide Ethernet switch market recorded revenues of $7.4 billion in the second quarter of 2021 (2Q21), an increase of 10.8% year over year. Meanwhile, worldwide enterprise and service provider (SP) router market revenues declined 0.5% year over year in 2Q21 to $3.9 billion. These results are from the International Data Corporation (IDC) Worldwide Quarterly Ethernet Switch Tracker and Worldwide Quarterly Router Tracker.

The Ethernet switch market’s annualized growth of 10.8% builds upon the 7.6% growth in the first quarter of 2021. For the first half of the year, Ethernet switch revenues are up 9.3% over 2020. Compared to the second quarter of 2019 – before the COVID-19 pandemic – revenues increased 3.8%.

From a geographic perspective, the 2Q21 Ethernet switch market had strong results across most parts the world. In Asia/Pacific, the People’s Republic of China revenues grew 11.6% year over year while Japan’s market increased 8.3%. More broadly in the Asia/Pacific region, excluding China and Japan, the market rose 20.5% year over year in the quarter, buoyed by the market in Singapore growing 58.2% annually.

Overall port shipments increased 28.4%, driven by strength in the non-datacenter portion of the Ethernet switch market. Non-datacenter Ethernet switch revenues grew 17.7% in 2Q21 with port shipments increasing 36.1%. The non-datacenter ethernet switch portion of the market makes up 88.6% of port shipments and 58.5% of total market revenues with the balance of revenues and port shipments in the datacenter portion of the market. In the datacenter segment, revenues rose 2.4% year over year, while port shipments declined 10.6%.

The higher-speed segments of the Ethernet switch market continue to see significant growth, driven by hyperscalers and cloud providers. Market revenues for 200/400 GbE switches grew 132.5% from the first quarter to the second quarter of 2021, with port shipments more than tripling (+206.0%) on a sequential basis. 100GbE revenues increased 15.4% on an annualized basis, while port shipments rose 11.4% year over year. 25/50 GbE revenues increased 25.6% year over year while port shipments rose 1.3%.
