General Description

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 HiGig™ 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.

Scalability

Switches based on the BCM5695 offer world-class scalability, and performance,

when used along with other StrataXGS™ 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+™ stacking

port supports explicit priority, port trunking, and mirroring functions across the

switching elements.

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.

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 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.

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.

Additional Information

Production-ready reference design kits such as the BCM95695K24U and

BCM95695R24S enable faster time-to-market for system vendors and come with

extensive support documentation and software. Please contact your local sales

representative for more information.
