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, policybased 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 HeadOf-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 I2C 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 nextgeneration, high-speed, embedded switching applications, such as Blade Servers and advanced TCA chassis platforms.
