Highly Integrated, Secure Offering Facilitates
IT/OT Network Convergence
SANTA
CLARA, Calif., Nov. 8, 2022
/PRNewswire/ -- Marvell Technology, Inc. (NASDAQ: MRVL),
a leader in data infrastructure semiconductor solutions, today
announced the extension of its campus networking portfolio into the
operational technology (OT) networks common to industrial and
critical infrastructure organizations. Marvell's Secure
Deterministic Ethernet solution, comprised of Prestera®
switches and Alaska®
PHYs, is designed for switch appliances used in these often-harsh
environments. By enabling the more widespread use of Ethernet in
the OT environment, the new solution facilitates the adoption
of modern IT tools and security methods in OT networks, enabling a
common management and automation approach from the cloud to the OT
network edge. According to 650 Group, the shift to Ethernet is
driving double-digit growth in this sub-segment, increasing
Marvell's addressable market.
The OT networks in which these switches operate require
precision timing and predictable latency—attributes not typically
required in corporate IT networks. Traditionally, proprietary
protocols have been required to meet these needs, known
collectively as deterministic networking. The new solution
addresses these deterministic networking requirements with a set of
Ethernet standards known as time-sensitive networking (TSN). With
TSN, virtually any kind of Ethernet traffic can share a network,
allowing siloed IT and OT networks to converge, thus reducing costs
and facilitating in OT networks the analytics, automation and
intelligence that are transforming IT networks.
In addition to being characterized by harsh physical
environments, networks in manufacturing and critical infrastructure
industries such as electric utilities, railways, and energy
production are at heightened risk of cyberattack. Risks are further
increased due to the location of some networking equipment, which
places it at relatively greater risk of physical security breach.
To better protect these networks, the new Prestera industrial-grade
switches with TSN offer industry-first device- and link-level
security, in the form of Secure Boot and MACsec.
For OEMs, semiconductor power, footprint and design complexity
are critical considerations. Unlike alternative approaches that
require a separate field-programmable gate array (FPGA) to process
TSN flows, the new switches integrate TSN functionality without
requiring an FPGA. A complete industrial networking solution
requires only a switch and one or more PHYs and, in some cases,
only a single, integrated chip. This architectural approach
dramatically reduces power, board space and device design
complexity.
The new Marvell® Secure Deterministic Ethernet
solution includes a family of ruggedized Prestera switches,
offering a comprehensive TSN feature set, and Alaska Ethernet PHYs.
The TSN standards enable reliable, deterministic real-time
communications over Ethernet by offering bounded latency, low delay
variation and extremely low packet loss. The Prestera DX1500
switch family scales from eight ports to 54 ports and is designed
to be paired with the Alaska E1781
series of 10/100/1000Base-T, octal-port copper transceivers. In the
case of the 8-port switch, the PHY is integrated.
"Ethernet-based communications technologies are increasingly
being adopted for industrial applications and devices, enabling
integration with IT. Real-time determinism and time-sensitive
networking technology, however, remain important requirements and
not features that are historically part of Ethernet," said
Anna Ahrens, senior research
analyst, Manufacturing Technology, at Omdia.
Deterministic Ethernet-based systems are expected to grow from
less than 15 percent of the Ethernet switches sold for industrial
use to nearly half by 2026, with the total industrial Ethernet
market climbing to approximately $1.7
billion, according to 650 Group.
"This new solution enables us to offer the most complete
portfolio of highly secure, TSN-capable industrial switches that
will help our customers accelerate their customers' digital
transformation and network convergence initiatives," said
John DaCosta, vice president of
marketing for the Switch Business Unit at Marvell. "As
standards-based deterministic networking gains traction, there's
new opportunity for traditional IT networking vendors to enter this
rapidly growing market."
