描述 Description

Broadcom’s Qumran3A is ideal for carrier Ethernet, Cell Site Routers, Mobile backhaul, PON OLT, Microwave access, aggregation routers and deep buffer Top Of Rack (TOR) switching.Qumran3A Ethernet switch SoC packs in a single device 2.4 Tb/s of Ethernet ports with rates ranging from 1GE up to 800GE, hierarchical traffic manager, scalable packet buffer memory and the Elastic Pipe™ packet processing.Integrated accelerators for carrier service management as well as hardware-managed stateful flow tracking at wire-speed provide visibility and control for carrier networks and distributed data centers traversing a wide area network (WAN).Qumran3A supports standard implementation for Ethernet rates, scaling to 100, 200, 400 and 800 Gigabit Ethernet ports and adds built-in MACSec and IPSec encryption at line rate on all network ports enable secure connectivity between off-premise locations.This unique combination enables equipment makers to revolutionize the Ethernet router equipment economics with a higher port density, integrated security mechanisms and lower power consumption in a smaller physical system size.Qumran3A delivers a complete set of advanced features for the most demanding carrier, campus and cloud environments. Packet buffer over up to 4 x 32b LPDDR5x interfaces enable 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).Qumran3A and the lower-capacity Qumran3u and Qumran3n combine the market-leading feature-set of StrataDNX™ with a wide and flexible set of physical ports and varying switch capacities, enabling a new generation of innovative low power fixed form factor switch routers ranging from 360Gb per second to 2.4Tb per second of routing, with integrated security and dense connectivity of up to 80 physical ports.
