BCM56800 System Diagram
The BCM56800 network switch is a high-density, 10-Gigabit Ethernet
switching chip solution with 20 ports. Each of these flexible ports
supports 10-Gigabit Ethernet or 1-Gigabit Ethernet. Additionally, the
BCM56800 integrates all the SerDes required to interface to applicable
copper and fiber physical interfaces. The integrated SerDes functionality
includes 10-Gbps XAUI interfaces 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.
In addition, the BCM56800 provides advanced security features that
improve network resiliency and reliability. Moreover, BCM56800
features advanced load balancing functionality that uses flow
information to provide high-percentage link utilization.
With 200 Gbps of aggregate switching bandwidth, BCM56800
represents the highest level of Ethernet switching integration in the
industry. This integration enables embedded switching vendors to
provide next-generation products at 10GE speeds that fit into the current
design form factors. This ability has many benefits, including reducing
the vendor development cost and creating additional value in current
generation systems through upgradability.
As the latest member of the StrataXGS switch family, the BCM56800
Software Development Kit preserves software continuity with Gigabit
Ethernet switches, reducing development cost and shortening the
product time to market.
The BCM56800's low power dissipation simplifies board design and
optimizes vendor board space.
In addition to a 32-bit PCI interface used to communicate with a local
CPU, the BCM56800 supports an I2C controller for communicating with
external devices such as serial EEPROM, flash memories, and parallel
port devices.
The advanced ContentAware™ engine supports ToS/DiffServ, policybased routing, priority tagging and remapping. The advanced packet
filtering and classification functions of BCM56800 make it ideal for
Utility computing applications where user segregation and network
security is critical.
The BCM56800 supports L2 switching with 4K VLANs, IPv4 and IPv6
full routing functionality, enabling it to become an direct extension of the
Enterprise Network. This provides additional value to customers by
eliminating the hardware and management cost of having intermediate
routers.
The BCM56800 implements congestion handling features such as HeadOf-Line blocking prevention and IEEE 802.3x flow control.
The BCM56800 relies on Broadcom’s modular switching architecture to
provide intelligent packet processing, network security and enhanced
managability at a low cost. The BCM56800 is an ideal solution for nextgeneration, high-speed, embedded switching applications, such as Blade
Servers and advanced TCA chassis platforms.
