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

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.
