BCM88480数据手册Broadcom中文资料规格书

描述 Description

Broadcom’s Qumran2a switch SoCs are ideal for carrier Ethernet, edge and core routers, mobile backhaul, data center cloud, transport and access market segments.
Qumran2a provides 800 Gb/s packet processing in a single device at high interface rates, while integrating a 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 the network.
This unique combination enables equipment makers to revolutionize the router equipment economics with a higher port density, lower power consumption and greater subscriber scale in a smaller physical system size.
Qumran2a supports standard implementation for Ethernet rates, scaling from 1 Gigabit Ethernet to 100, 200 and 400 Gigabit Ethernet ports. Built-in InterLaken interfaces enable direct connectivity to external framers and processors.
Qumran2a integrates a Flexible Ethernet (FlexE) interface. FlexE can be used in backhaul, transport and DCI applications for finer control over the transmitted traffic. 
The 16-nanometer (nm) StrataDNX switch family offers the following device options:
BCM88480 – A 800 Gb/s packet processor and traffic manager for centralized carrier Ethernet switch router, data center chassis, and enterprise campus applications Qumran2a delivers a complete set of advanced features for the most demanding carrier, campus and cloud environments. The device supports DRAM-based deep 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).
Qumran2a combines 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.
