描述 Description

Broadcom’s Jericho2c+ switch SoCs, combined with Ramon, are ideal for carrier Ethernet, edge and core routers and data center cloud networks.
Jericho2c+ provides 14.4 Tb/s packet processing in a single device at a high interface bandwidth while integrating a scalable multi-terabit switch fabric, hierarchical traffic manager, scalable packet buffer memory and the Elastic Pipe™ packet processing.
Integrated accelerators for carrier service management provide visibility and control for carrier networks and distributed data centers traversing any network.
This unique combination enables system vendors to revolutionize the router equipment economics with a higher port density, lower power consumption and greater subscriber scale in a smaller physical system size.
Jericho2c+ supports standard implementation for Ethernet rates, scaling from 10 Gigabit Ethernet to 100, 200 and 400 Gigabit Ethernet ports. 
Built-in MACSec and IPSec at line rate on all network ports enable secure connectivity between off-premise locations.
The StrataDNX switch family offers the following device options:
BCM88850 – A 14.4 Tb/s packet processor and traffic manager with DNX fabric interfaces for carrier Ethernet switch router, data center chassis, and enterprise campus applicationsBCM88690 – A 10 Tb/s packet processor and traffic manager with DNX fabric interfaces for carrier Ethernet switch router, data center chassis, and enterprise campus applicationsBCM88800 – A 4.8 Tb/s packet processor and traffic manager with DNX fabric interfaces for carrier Ethernet switch router, data center chassis, and enterprise campus applicationsBCM88790 – A high density switch fabric device providing 9.6 Tb/s throughput per device enabling over 200 Tb/s switching capacity in a single modular system when combined with the BCM88850, the BCM88690 and the BMC88800 Jericho2c+ delivers a complete set of advanced features for the most demanding carrier, campus and cloud environments. The device supports low power, high bandwidth HBM packet memory offering up to 160X more traffic buffering compared with on-chip memory, enabling zero-packet-loss in heavily congested networks. In-field reconfigurable, flexible and elastic packet processing engines allow for customer-specific forwarding paradigms or future support of new and emerging protocols.
On-chip hierarchical traffic management ensures per-subscriber bandwidth guarantees, required by carrier networks to deliver on service level agreements (SLAs).
Jericho2c+, with the BCM88690, the BCM88800 and the BCM88790, combine the market-leading feature-set of StrataDNX™ with high bandwidth capacity, enabling a new generation of innovative network switch systems. 
Broadcom's StrataDNX family of expandable products, together with the StrataXGS® Trident and Tomahawk® SoCs, provide the industry’s most comprehensive end-to-end portfolio of switching solutions across the carrier, data center and enterprise markets.
