BROADCOM’S NEW 65 NM “SMART” SWITCH ENABLES MASS
DEPLOYMENT OF GIGABIT ETHERNET FOR THE CONSUMER MARKET
• Highly integrated, 65-nanometer (nm) process, non-blocking
5-port 10/100/1000 switch silicon that integrates:
• Five 10/100/1000 PHYs
• Two fully integrated, GMII/RGMII/MII interfaces Inband
Management Ports (IMP) for glueless connection to a CPU or
WLAN.
• Patented ease of use capabilities:
• LoopDTech™ technology provides loop detection without
running Spanning Tree Protocol (STP).
• CableChecker™ enables advanced cable diagnostics based on
the Broadcom
®
Convergence Algorithm.
• Virtual Local-Area Network (VLAN)
• IEEE 802.1Q-based VLAN with 4K entries
• Port-based VLAN
• VLAN double tagging (Q-in-Q): Supports addition and
removal of one or two tags and VLAN translation.
• MAC-based VLAN
• Quality of Service (QoS)
• Four selectable QoS per port; SP and WRR and any
combination of SP and WRR scheduling.
• Port, MAC, IEEE 802.1P, and IPv4/IPv6 DSCP-based QoS
• Performance
• 9 KB jumbo frame support; wirespeed performance for all
fame sizes.
• 4K MAC addresses with automatic learning and aging
• 64 multicast group support
• 128 KB packet buffer
• Allows data packet inspection to be offloaded from a product’s
Central Processing Unit (CPU), thereby freeing up CPU
bandwidth to provide superior performance.
• Security
• IEEE 802.1x support for secure user authentication.
• DoS prevention hardware.
• TCAM-based ACLs: 256 policy rules, rule-based filtering, and
QoS class modification; rule-based metering and accounting;
128-byte deep packet header lookup, 28-byte matching.
• Traffic control and network resiliency
• Storm control and port-based ingress/egress rate control
•
Spanning Tree support (Rapid Spanning Tree and Multiple Spanning
Trees—up to 16)
• IPv4 IGMP and IPv6 MLD snooping
•
IEEE 802.3x programmable per port flow control and
backpressure
• Port mirroring, LLDP, LACP
• Industry’s first 65 nm 5-port Gigabit Ethernet (GbE) switch
in a single chip enables ubiquitous deployment of GbE to
consumer electronic devices and home networking
equipment.
• Flexible solution enables cost-optimized consumer system
designs that require scalable interfaces to address every facet
of the consumer market segment.
•
Broadcom-patented features provide unique and easy to use
solutions to network loop and cable problems. LoopDTech
automatically detects network debilitating loops, reducing
system cost. CableChecker can be run at any time to detect
cable length and problems without interrupting live traffic
and keep consumers connected.
• VLAN feature ensures proper Layer 2 isolation and security.
• Double tagging enables carrier class devices.
• MAC-based VLAN provides wireless AP security support.
• Integrated QoS technology supports all types of consumer
connections, including VoIP, video, audio, and data. Priority
can be assigned each traffic type to ensure guaranteed
delivery of time-sensitive packets and efficient use of network
bandwidth.
• Performance enhanced architecture supports line-rate data
transfer to ensure consumer data (video, audio, pictures, and
files) are sent at wirespeed.
• Increased network security that blocks unwanted access.
• Provides an easy way to troubleshoot security problems.
• Provides enhanced network security and resiliency to keep the
home network running efficiently.
• Traffic control allows rate control, which identifies and
prioritizes different data packet types within the switch while
simultaneously assigning voice packets a higher priority for
outbound communications, in addition to Layer 2 and
Layer 3 multicast table support for IPTV.
