High-Density and Line Rate Performance

The BCM5665 network switch is the most advanced multi-layer

scalable, single-chip solution for high density 48 x 10/100 Mbps ports

and 4 x 10/100/1000 Mbps Ethernet uplinks at aggregate line rate of 28

Mpps performance.

Ultra-Scalability

An integrated 10 Gbps XAUI HiGig port allows the BCM5665 to scale

with other StrataXGS family switches. Multiple units can be networked

for stackable or modular switch configuration in a system providing up

to providing up to hundreds of Fast Ethernet, Gigabit Ethernet and 10

Gigabit Ethernet ports. The 10 Gbps HiGig Expansion port supports all

key switch features, such as explicit priority, port trunking, mirroring

and VC label swap functions, transparently across switch elements.

Metro Ethernet L2 VPN Support

Supporting the latest Metro Ethernet L2 VPN applications, the

BCM5665 offers double 802.1Q VLAN stacking, also known as Q-in-Q.

This allows enterprise and service provider networks to breakthrough the

4K VLAN tag limitation. Further, the BCM5665 also provides MPLS

Tunnel/VC packet labeling for standards-based IETF L2 VPN via

MPLS.

Advanced QoS

With eight Class of Service (CoS) queues via SP, RR, WFQ, and WRR

distribution, the BCM5665 enables full range of service applications

such as low latency VoIP and real time video, as well as mission-critical

data.

L2/L3 Switching

Optimized for the most demanding network switching requirement, the

BCM5665 integrates both auto-learning/aging MAC and IP LPM tables.

Advanced Ethernet features, such as multiple and rapid spanning tree

(802.1s and 802.1w), flow control (802.3x), prioritization (802.1p) and

9K jumbo frames, are fully integrated. All L2/L3 traffic is switched at

line rate. For load balancing as well as redundancy purposes, ECMP and

WCMP are incorporated. Up to 32 trunk groups (8 links per group) can

be assigned for link aggregation (802.3ad).

Hardware-Based Traffic Management

Providing line rate packet filtering and classification, the advanced Fast

Filter Processor (FFP) offers ContentAwareTM network processing per

port. It supports TOS/DiffServ, rate limiting, policing, shaping,

metering, scheduling, priority tagging and remapping down to flows as

small as 64 kbps making it ideal for committed bandwidth usage and

firewall applications.

Layer 2 and IP Multicast

Designed for increasing multicast applications, the BCM5665 switches

all L2/L3 multicast packet sizes at line rate. IPMC packets are hardware

replicated up to 8 and 32 VLANs across the Fast and Gigabit Ethernet

ports, respectively. Multicast traffic can also be managed by three port

filtering modes to control the distribution behavior
