Provides hardware support for a number of multicast applications, such as video and audio conferencing, web training Multiple classes of service (CoS) enable the switch to prioritize latency-sensitive applications, such as VoIP and video applications Built-in 10 Gigabit Ethernet/XAUI SerDes, in addition to integrated data and address memory, reduces overall system cost and design complexity Broadcom Switch API compatibility enables software reuse and faster time to market Small package and low-power enables cost effective and high performance system design TARGET APPLICATIONS * High performance 10 Gigabit Ethernet multilayer switching applications targeting the following types of systems: * Stand-alone systems * Stackable systems * Modular chassis systems * High-end server blades * * * * Support for 128 StrataXGSTM devices using module remapping Supports port mirroring across the stack Feature parity with BCM5695 multilayer switch Low power ~4 W 10 Gbps Ethernet XPIC FFP PCI Functional Design of BCM5675-Based 48-Port GE Switch With 66 MHz GE Ports and Stacking 2 I2C x 10 ARL MMU CMIC CPU Bus IPIC 10 Gbps HiGigTM OVERVIEW Functional Design of 48-Port Gigabit Ethernet Switch Based on BCM5674 with 2x10 GbE Ports and Stacking 2x 10 GbE 2x HiGigTM SDRAM BCM5675 PCI FLASH BCM8703 BCM5674 CPU BCM5695 BCM5464 BCM5695 BCM5464 BCM5695 BCM5464 BCM5695 BCM5464 12x GbE 12x GbE 12x GbE 12x GbE The BCM5674 10-Gigabit Ethernet switch is a scalable, multilayer switch-on-chip member of the StrataXGS family. The BCM5674 is a dual-port switch, which supports a 10 Gigabit Ethernet (IEEE 802.3ae) port and a HiGigTM uplink port. The 10 Gigabit Ethernet port can be used to interface to the XENPAK module via the XAUI interface. The HiGig uplink expansion port supports explicit priority and mirroring functions across the stack. The HiGig port can be used to interconnect up to 128 switching devices, which enables high port density switching applications. The BCM5674 supports VLAN double tagging that is compatible with other StrataXGSTM devices. The switch can also be used in loopback mode enabling VLAN double tagging support for the Gigabit Ethernet ports on the BCM5695. The built-in Fast Filter Processor (FF) provides ContentAwareTM network processing. The FFP supports functions such as ToS/DiffServ mapping, rate limiting, policing, priority tagging, and metering functions. The enhanced packet classification feature of the FFP enables cutting-edge applications such as VoIP and firewalls. The BCM5674 provides hardware support for IP multicast as well as IP multicast replication. This enables a number of multicast applications, such as Web training and audio/video conferencing. The BCM5674 supports advanced packet flow control, such as head-ofline blocking prevention and IEEE 802.3x compatible full-duplex control.
