48-Port 10-GbE Switch with BCM56700 and BCM56802
The BCM56802 network switch is a high-density, 10-Gigabit Ethernet
switching chip solution with 16 ports. All 16 ports can flexibly support
HiGig2/HiGig+/HiGig/10-GbE/1-GbE. Additionally, the BCM56802
integrates all the SerDes required to interface with applicable copper and
fiber physical fabrics.
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 192 Gbps of aggregate switching bandwidth, the BCM56802
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 BCM56802'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 BCM56802 make it a
seamless fit utility for computing applications where user segregation
and network security is critical.
In addition, the BCM56802 provides advanced security features that
improve network resiliency and reliability. Moreover, the BCM56802
features advanced load balancing functionality that uses flow
information to provide high-percentage link utilization.
The BCM56802 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 BCM56802
Software Development kit preserves software continuity with Gigabit
Ethernet switches, reducing development cost and shortening the
product time-to-market.
The BCM56802 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 BCM56802 supports an I²C controller for communicating with
external devices such as serial EEPROM, flash memories, and parallel
port devices.
The BCM56802 relies on Broadcom’s modular switching architecture to
provide intelligent packet processing, network security and enhanced
manageability at a low cost. The BCM56802 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 BCM56802
can also be used to build cost-effective, high-density 10GbE switches.
