The BCM5650 network switch is the most advanced multi-layer, single

chip solution for high density 24 x 10/100 Mbps ports and 4 x 10/100/

1000 Mbps Ethernet uplinks.

With an aggregate line rate of 9.5 Mpps, the BCM5650 offers hardware

switching on both L2 and L3 traffic. Filtering, policing, priority tagging

can be performed in real time with no impact on forwarding

performance.

Supporting the latest Metro Ethernet L2 VPN applications, the

BCM5650 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, BCM5650 also provides MPLS

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

MPLS.

With 8 Class of Service (CoS) queues via SP, RR, WFQ and WRR

distribution, the BCM5650 enables full range of service applications

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

data.

Optimized for the most demanding network switching requirements, the

BCM5650 integrates 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 frame 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 (eight links per group)

can be assigned for link aggregation (802.3ad).

Providing line-rate packet filtering and classification, the advanced Fast

Filter Processor (FFP) offers ContentAware™ 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.

Designed for increasing multicast applications, the BCM5650 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.
