48-Port GbE + 10-Port 10-GbE L2/L3 Switch with BCM56801, BCM56701, and BCM56502
The BCM56801 network switch is a high-density, 10-Gigabit Ethernet
switching chip solution with 18 ports. Ten ports can support 10-GbE or
1-GbE. The other eight ports can flexibly support HiGig2/HiGig+/
HiGig/10-GbE/1-GbE. Additionally, the BCM56801 integrates all the
SerDes required to interface to applicable copper and fiber physical
interfaces.
The integrated SerDes functionality includes 10-Gbps XAUI and 1-Gbps
SGMII PHY interfaces. The integrated SerDes complies with the CX-4
standard and PICMG3.1 standard, which ensures interoperability with
Ethernet line cards in an Advanced TCA chassis.
With 196 Gbps of aggregate switching bandwidth, the BCM56801
represents the highest level of Ethernet switching integration in the
industry. This integration allows embedded switching vendors to provide
next-generation products at 10-GbE speeds, as well as an ideal fit into
current design form factors. This capability has many benefits, including
reducing vendor development cost and creating additional value in
current generation systems through upgradability.
The BCM56801's low power dissipation simplifies board design and
optimizes vendor board space.
The advanced ContentAware engine supports ToS/DiffServ, policy-
based routing, priority tagging, and remapping. The advanced packet
filtering and classification functions of the BCM56801 make it a
seamless fit utility for computing applications where user segregation
and network security is critical.
In addition, the BCM56801 provides advanced security features that
improve network resiliency and reliability. Moreover, the BCM56801
features advanced load balancing functionality that uses flow
information to provide high-percentage link utilization.
The BCM56801 supports L2 switching with 4K VLANs, IPv4, and IPv6
full routing functionality, enabling it to become a direct extension of the
enterprise network. This provides additional customer value by
eliminating the hardware and management costs of maintaining
intermediate routers.
As the latest member of the StrataXGS switch family, the BCM56801
Software Development kit preserves software continuity with Gigabit
Ethernet switches, reducing development cost and shortening the
product time-to-market.
The BCM56801 implements congestion handling features such as Head-
Of-Line blocking prevention and IEEE 802.3x flow control.
In addition to a 32-bit PCI interface used to communicate with a local
CPU, the BCM56801 supports an I
2
C controller for communicating with
external devices such as serial EEPROM, flash memories, and parallel
port devices.
The BCM56801 relies on Broadcom’s modular switching architecture to
provide intelligent packet processing, network security and enhanced
manageability at a low cost. The BCM56801 is an ideal solution for next-
generation, high-speed embedded switching applications, such as Blade
Servers and Advanced TCA computer platforms.
Together with the BCM56700 as a centralized fabric, the BCM56801
can also be used to build cost-effective high-density 10-GbE switches.
