With an aggregate line rate of 9.5 Mpps, the BCM5651 offers hardware switching on L2 traffic. Filtering, policing, and priority tagging can be performed in real time with no impact on forwarding performance. Supporting the latest Metro Ethernet L2 VPN applications, the BCM5651 offers double 802.1Q VLAN stacking, also known as Q-inQ. This allows enterprise and service provider networks to breakthrough the 4K VLAN tag limitation. Further, BCM5651 also provides MPLS tunnel/VC packet labeling for standards-based IETF L2 VPN via MPLS. With eight CoS queues via SP, RR, WFQ, and WRR distribution, the BCM5651 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 BCM5651 integrates a 16K entry auto-learning/aging MAC. 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 switching are fully integrated. All L2 traffic is switched at line rate. For load balancing as well as redundancy purposes, link aggregation is 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. The BCM5651 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 BCM5651 switches all L2 multicast packet sizes at line rate. For L2 multicast, up to 256 multicast addresses are supported. Multicast traffic can also be managed by three port filtering modes to control the distribution behavior.
