Multi-Service Intelligence
12 x GbE
The BCM5695 is an integral component of the highly modular, scalable switch architecture. Each port supports 10/100/1000-Mbps Ethernet with copper or fibre physical interfaces. The BCM5695 has a fully integrated SerDes with a XAUI interface on the HiGigTM port and an SGMII interface on the GbE ports. The flexibility and modularity of the BCM5695 switch architecture makes it suitable for a wide range of applications including stackable, fixed, chassis, blade server, and metro Ethernet switching.
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 integrated security (IEEE 802.1x), wirespeed access control lists, policy-based rate limiting, IP Multicast replication, IPv6 awareness, and advanced Layer 3 functionality 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.
Scalability
Switches based on the BCM5695 offer world-class scalability, and performance, when used along with other StrataXGSTM family components. A BCM5695-based switch fabric can scale up to as many as 1,536-GbE ports or 128 10-GbE ports in the same configuration. A multistage switch fabric using the StrataXGS family can have a bandwidth capacity of up to 1.5 Tbits. The 12-Gbps HiGig+TM stacking port supports explicit priority, port trunking, and mirroring functions across the switching elements.
Superior Performance
The BCM5695 delivers wirespeed switching performance across all ports simultaneously. The effective bandwidth of each HiGig+ interface is 24 Gbps (12 Gbps, full-duplex). The BCM5695 also introduces very low switching latency, enabling very high-quality transmission of voice, video, and data traffic. The BCM5695 supports advanced packet flow control such as head-of-line blocking prevention and IEEE 802.3x-compatible full-duplex control.
Advanced QoS
The highly flexible ContentAware packet filtering and classification engine in the BCM5695 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.
