Each port supports 10/100/1000-Mbps Ethernet with copper or fibre physical interfaces. The BCM5698 has a fully integrated SerDes with an SGMII interface on the GbE ports. The flexibility and modularity of the BCM5698 switch architecture makes it suitable for a wide range of applications including fixed, blade server, and metro Ethernet switching. Advanced QoS The highly flexible ContentAware packet filtering and classification engine in the BCM5698 switch family provides a common application platform across the entire StrataXGS™ product line. It supports ToS/DiffServ, rate limiting, policing, shaping, marking, and remarking. These features enable cutting-edge voice and video applications based on the Internet Protocol. Multi-Service Intelligence Superior scalability, high availability, and performance enable network designers to meet the growing needs of mission-critical enterprise applications. Support of multi-service intelligence in the form of 10 x GbE integrated security (IEEE 802.1x), wirespeed access control lists, policybased rate limiting, IP Multicast replication, and IPv6 awareness ensures robust network design. New metro Ethernet features extend the security boundary beyond the enterprise networks into service provider networks with support for double VLAN tagging (IEEE 802.1Q) and VLAN translation. Superior Performance The BCM5698 delivers wirespeed switching performance across all ports simultaneously. The BCM5698 also introduces very low switching latency, enabling very high-quality transmission of voice, video, and data traffic. The BCM5698 supports advanced packet flow control such as head-of-line blocking prevention and IEEE 802.3x-compatible fullduplex control. Additional Information Production-ready reference design kits enable faster time-to-market for system vendors and come with extensive support documentation and software.
