According to IDC data, the overall 100Gb Ethernet revenue in the first quarter of 2018 increased by 83.8% to $742 million 500 thousand in the first quarter, and the first quarter port shipments increased by 117.7% over the same period. Dell 'Oro Group researchers say that the shipments of 100G Ethernet ports are expected to reach 12 million this year, compared with about 1 million on 100G Ethernet ports in 2016.
A recent study by PwC further explains why high-speed networks are needed. "As companies gradually break away from traditional enterprise data centers, workload becomes increasingly unitary. "They're becoming more decentralized, more mobile, and more like workloads typically associated with very large-scale environments," PwC writes. "In the next 1-3 years, almost all major workload will be transferred from internal deployment to public cloud. Applications will be more dependent on the network, and because of the distribution and dynamics of the workload, the network will become more important.
Roland Acra, senior vice president and general manager of CISCO's data center business group, says the demand for high-speed ports and more data driven from the dense edges of the network are pushing the backbone to upgrade.
"It is mainly driven by the evolution of the network interface card NIC on the server. Most server connections are basically between 1G and 10G. Now, the server that connects to the top switch has changed a lot from 10G to 25G or 50G, which makes the overhead uplink want to reach higher density, 100G, "Acra said.
From 10G to 25G to 100G Ethernet
"The price of 25G is basically the same as that of 10G and 100G. The use of four channel 25GE, 100GE backbone platform requires less wiring, and lower space requirements and costs. Backward compatibility provides an additional choice for simplifying conversion, while extending the value of current assets, "CISCO said.
"Cloud and software-defined architectures are shaking the Ethernet switch and router markets," wrote Petr Jirovsky, IDC's global network tracking research manager. "The continuing price decline and the growing difference between the cloud and communication service providers and the purchase preferences of the enterprises have created a challenging environment for the suppliers, as well as the opportunity for the end users."
Cisco, Juniper, Arista, HPE and HUAWEI aim at data center.
Cisco, Juniper, Arista, HPE and HUAWEI are only a handful of vendors that actively seek market opportunities for high-speed and traditional Ethernet. Juniper recently launched EX4650 High Density 25/100 Gbps Switch, which supports 48 100G Ethernet ports, or 48 25G ports, and eight 100G uplink.
But the driver of 100G is only the beginning of high-speed Ethernet. Dell Oro reported earlier this year that it is estimated that by 2020, 400G will account for 20% of the exchange revenue of data centers. It is estimated that in the next five years, the higher speed of 100G, 200G, 400G and 800G will increase significantly.
"In December 2017, Broadcom announced the launch of a 56G SerDes-based Tomahawk 3 chip with innovative technology and Nephos," Boujelbene said. "We expect commercial chips based on 56G SerDes to boost shipments of 200 Gbps and 400 Gbps, with 400 Gbps accounting for the majority. By 2020 to 2021, we expect 112G SerDes to push another speed upgrade cycle to drive 800 Gbps port shipments, plus another wave of 200 Gbps and 400 Gbps shipments.
Cisco's Accra says there are two to three years to go before the 400 gigabytes, or at least until the 400 gigabytes plummet is attractive enough. "400G is still a concern for cloud and service providers. CISCO has not taken the 400G link as a priority. "
However, Juniper seems to want to achieve faster 400G Ethernet speed than now. (Juniper is looking forward to becoming the first person in 400GbE)
