Network Connectivity/Ethernet Controllers
Intel® 82579 GbE Controller
Network Connection
High-performance Gigabit Network Connectivity with Support for Intel® vPro™ technology.
Overview
The Intel® 82579 family of Gigabit Ethernet Controllers provides compact, single-port
integrated physical layer devices that connect to the Intel® 6 Series Express chipsets.
The 82579 family of products are gigabit copper networking components for mobile,
desktop, workstation, embedded and value-server designs that have critical space and
power constraints.
Key Details
Simplified installation and Maintenance:
Intel® 82579LM products also support
the Intel Stable Image Platform Program
(SIPP), which provides system image sta-
bility (both hardware and software) and
consistency for at least 12 months from
the product launch date. Helping IT better
manage their client environment.
Reduced Power and Energy Savings:
The Intel® 82579 family reduces the
power consumption in all power states
compared to previous generations of Intel
controllers. While in active-idle Intel® has
implemented Energy Efficient Ethernet
(EEE)1, a new IEEE* standard. With EEE
Intel has reduced the idle power of the
gigabit link from about 500 mW to nearly
50 mW providing a significant energy
savings. For mobile designs, Intel’s Auto
Connect Battery Saver can help reduce
the cable-disconnected power of the chip
to about 30 mW while still maintaining full
functionality. The products also support
advanced link downshifting capabilities
to provide additional power headroom for
system regulatory compliance (such as
Energy Star*) by lowering the link speed
under certain conditions to save power.
Performance-Enhancing Features: Each
of the Intel® 82579 family of network
components includes advanced interrupt-
handling features to reduce CPU over-
heard. Other performance-enhancing fea-
tures include offloading TCP/UDP (for both
IPv4 and IPv6) checksum calculations and
performing TCP segmentation. Advanced
features such as Jumbo Frame support for
extra-large packets and Receive Side Scal-
ing are also supported.
Advanced Security: The Intel® 82579LM
supports the latest Ethernet security
standard known as MACsec3 (IEEE stan-
dard 802.1ae). MACsec provides robust
security at a low level of the system by
providing MAC layer (layer 2) encryption
and authentication capability hop-by-hop.
This enables IT to fully encrypt network
traffic, but still perform traffic shaping
and analysis at the router and doesn’t
interfere with existing network protocols.
Intel® Business Client Features: The
Intel® 82579LM supports Intel® AMT2,
which is a part of Intel’s vPro™ technology
on notebooks, desktop, and workstation
systems. Intel vPro technology provides
built-in manageability, proactive security,
and energy-efficient performance for
business applications.
Flexible, Low-Cost System Design:
The Intel® 82579 family of networking
components provide a small package (6x6
mm) networking option for convenient
board layout. The Intel® 82579 has flexible
power options including sharing the 1.05
Vdc supply with the chipset or it can be
configured using the integrated switching
voltage regulator (iSVR), removing the
need for an external regulator and reduc-
ing overall cost and board space. Addition-
ally, the 82579 family of products help
to reduce board space by using a shared
FLASH design. Finally, low thermal design
power (TDP) helps improve board place-
ment flexibility.
