# Jericho4 / BCM99450

## Jericho4 — 51.2 Tb/s StrataDNX™ Scalable Ethernet Switch Router Series

Broadcom’s Jericho4 is ideal for large-scale and high-density Ethernet network switching, carrier Ethernet, edge and core routers, peering, data center and cloud applications.

Jericho4 Ethernet switch SoC packs 25.6 Tb/s of Ethernet ports at rates up to 800GE and 1.6TE, hierarchical traffic manager, scalable packet buffer memory, the Elastic Pipe™ packet processing and a non-blocking fabric interface to the Ramon fabric elements.

Integrated accelerators for carrier service management provide visibility and control for carrier networks and distributed data centers traversing a wide area network (WAN).

This unique combination enables equipment makers to revolutionize the Ethernet router equipment economics with a higher port density, lower power consumption and greater subscriber scale in a smaller physical system size.

Jericho4 supports standard implementation for Ethernet rates, scaling to 100, 200, 400, 800 and 1600 Gigabit Ethernet ports and adds built-in MACSec and IPSec encryption at line rate on all network ports, enabling secure connectivity between off-premise locations.

Jericho4 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, which are required by carrier networks to deliver on service level agreements (SLAs).

Jericho4 combines the market-leading feature-set of StrataDNX™ with high-bandwidth capacity, enabling a new generation of innovative Ethernet router systems.

The Jericho4 switch SoCs, combined with the 102.4 Tb/s Ramon4 fabric elements, create the industry-largest scalable routers and switches. The market-leading feature-set of StrataDNX™ and the high-bandwidth capacity, enable a new generation of innovative network switch systems.

Broadcom's StrataDNX family of expandable merchant silicon 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.
