BCM56580 System Diagram
The BCM56580 network switch is a high-density, 2.5-Gigabit Ethernet
switching chip solution with 20 ports. Additionally, the BCM56580
integrates all the SerDes required to interface to applicable copper and
fiber physical interfaces. The integrated SerDes functionality includes
10-Gbps XAUI interfaces and 2.5/1-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 80 Gbps of aggregate switching bandwidth, BCM56580 represents
a high level of Ethernet switching integration that enables embedded
switching vendors to extend the life of their existing GbE system designs
by providing a performance upgrade using the same physical enclosures
and backplanes. This ability has many benefits, including reducing the
vendor development cost and creating additional value in current
generation systems through upgradability.
The BCM56580'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 BCM56580 make it ideal for
Utility computing applications, where user segregation and network
security is critical.
In addition, the BCM56580 provides advanced security features that
improve network resiliency and reliability. Moreover, the BCM56580
features advanced load balancing functionality that uses flow
information to provide high-percentage link utilization.
The BCM56580 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 value to customers by
eliminating the hardware and management cost of having intermediate
routers.
As the latest member of the StrataXGS switch family, the BCM56580
Software Development Kit preserves software continuity with Gigabit
Ethernet switches, reducing development cost and shortening the
product time-to-market.
The BCM56580 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 BCM56580 supports an I
2
C controller for communicating with
external devices such as serial EEPROM, flash memories, and parallel
port devices.
The BCM56580 relies on Broadcom’s modular switching architecture to
provide intelligent packet processing, network security, and enhanced
manageability at a low cost. The BCM56580 is an ideal solution for next-
generation, high-speed, embedded switching applications, such as Blade
Servers and advanced TCA chassis platforms.
