BCM5650 Block Diagram
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.
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).
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.
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.
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.
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.
