Through its advanced ContentAwareTM feature set, the StrataSwitch IITM product family supports advanced applications and services, at wire speed, with nonblocking performance. The BCM5616 uses 60 million transistors with 1 MB of internal memory to integrate the functionality of large board designs into a single chip. This level of integration allows the BCM5616 to sustain line rate on all 24 Fast Ethernet and 2-Gigabit Ethernet ports for Layer 2 switching and all L2-L7 processing applications. The StrataSwitch II fast filter processor (FFP) delivers line rate packet processing to support policy management, VoIP, and firewall applications. The data packet memory can be extended from 4 MB to 64 MB using commodity SDRAM in either a 128-bit-wide interface or a 64-bit-wide interface. The StrataSwitch family supports using the Gigabit ports in a stacking link mode, giving you tremendous scalability, configuring your switching system. The BCM5616 also provides a wide range of choices in levels of manageability and solution costs. For example, the BCM5616 provides a low-cost I2C interface for unmanaged applications, as well as a 33/50-MHz PCI interface for higher management and network service requirements. The flow metering and monitoring of the StrataSwitch II enables many new applications and services. ISPs can benefit from the metering capabilities of the StrataSwitch II, eliminating unregulated bandwidth from over-consuming their network. Using the monitoring features of the FFP, IT managers can gain tremendous insight to the utilization of their current network resources and optimize those resources accordingly.
