DASH Typical System Implementation Diagram
The BCM5761E Broadcom NetXtreme® controller is a fully integrated
10/100/1000BASE-T Gigabit Ethernet (GbE) media access control and
physical layer transceiver solution for high-performance network
applications. The BCM5761E combines a triple-speed, IEEE 802.3™compliant media access controller (MAC), PCI Express bus interface,
on-chip buffer memory, and integrated physical layer transceiver in a
single device. The BCM5761E is fabricated in a low-voltage silicon
process, providing an ultralow power solution. By itself, the BCM5761E
provides a complete single-chip GbE LOM solution.
The BCM5761E includes a 10/100/1000 Mbps Ethernet MAC with fullduplex and half-duplex capability at all speeds. Support for the following
IEEE 802.3 functions is featured in the MAC: VLAN tagging, Layer 2
priority encoding, and full-duplex flow control.
The BCM5761E controller offers IPsec task offload capabilities
compliant with Microsoft v2 logo requirements. This capability enables
IT professionals to deploy IPsec technology on their existing network
with no performance penalty, while maintaining low CPU utilization and
high network capacity by offloading all the cryptographic processing to
the hardware.
In-line offload architecture in the BCM5761E enables network security
at an extremely low cost. With network topologies becoming more
complex because of increased mobility and remote workers, virus and
worm security threats have become more sophisticated. IPsec protocols
operate at the network layer and enable end-to-end authentication and
encryption between clients and servers, allowing efficient network
segmentation and isolation.
The BCM5761E integrates an on-chip Application Processing Engine
(APE) with its runtime memory providing a complete Web servicesbased management functionality via Broadcom TruManage technology.
This single-chip highly integrated product offers a scalable and
centralized architecture, which, combined with a highly optimized
firmware and software, enables low-power, secure, fault-tolerant, and
cost-effective implementation.
Target applications of the BCM5761E:
• Mobile PC LOM
Software drivers available:
• Windows® 2000, Windows NT®, Windows XP®, and
Windows Vista®
• Linux® 2.2, 2.4, and 2.6
