BCM56330 Block Diagram
Each of the BCM56330 family is a highly integrated 24-port multilayer
GbE switch with four ports of 10-GbE XAUI uplinks or four ports of
1-GbE/2.5-GbE uplinks. The GbE ports support SGMII as well as
integrated SerDes for direct fiber (1000BX and 100FX) connectivity.
The BCM56330 family are purpose-built for next-generation Enterprise
and Metro Ethernet access applications. This product family offers an
8-port GbE configuration with uplinks or 24-port GbE configuration
with uplinks. Two BCM56330 devices can be connected together by two
ports of 13G XAUI-over-HiGig stacking protocol to create a
nonblocking 48-port switch.
The BCM56330 family supports nonblocking L2 switching and L3
routing, which are key features for Carrier Ethernet and enterprise
networking applications.
The BCM56330 family delivers key Metro Ethernet features:
•
Standardized Services
- Q-in-Q, 802.1ad provider bridging, MPLS/VPLS, VPWS,
pseudowire, and PBB/PBT support
- L2 and L3 VPNs
- STP for control protocol
•
Scalability
- Supports platforms from 8 ports to 48 ports of GbE
- 10-GbE ports for aggregation
•
Reliability
- Hardware support of STP, MSTP, RSTP
- 802.1ag and ITU Y.1731 Ethernet OAM for link failure detection
•
Quality of Service
- Per-flow metering capability with multistage ContentAware
engine
- VLAN shaping ensures provider-class SLA
- Highly optimized packet buffer architecture for burst absorption
and multicast traffic
•
Service Management
- 802.1ag Ethernet OAM message support
- Multistage ContentAware engine enables class-based
classification
- VRF
The BCM56330 family can be managed by a host CPU via PCIe™ or
BSC.
