Aiming for new high volume markets and appliances at the edge of the carrier network, Broadcom announced two new product families in its StrataDNX switch portfolio. The new devices range from 30Gbps to 300Gbps and offer similar capabilities and programming models as Broadcom’s flagship devices.
The newly announced StrataDNX switch family includes the following device options:
- BCM88476 – A 300 Gbps packet processor and traffic manager including StrataDNX fabric interfaces compatible with BCM88750 and BCM88770 Fabric Elements, plus external packet buffer and table expansion. (“Kalia”)
- BCM88470 – A single-chip packet processor and traffic manager delivering 160 to 300 Gbps of Ethernet capacity with external packet buffer and table expansion. (“Qumran-AX”)
- BCM88270 – A small footprint single-chip packet processor and traffic manager delivering 30 to 120 Gbps of Ethernet capacity with external packet buffer expansion. (“Qumran-uX”)
Each device provides high performance carrier-grade packet processing, an integrated hierarchical traffic manager, external packet buffers with enhanced buffer management and advanced packet processing with expandable tables. Select members of the product family also provide path for expansion capabilities, with the industry leading StrataDNX switch fabric interface, and external table lookup expansion for Broadcom Knowledge Based Processors (KBP).
The Kalia, Qumran-AX & Qumran-UX families of products are complementary to Broadcom’s high-capacity StrataDNX Jericho and Qumran-MX SoCs.
“With Qumran-AX & Qumran-UX we are excited to deliver StrataDNX technology to higher volume metro markets,” said Ram Velaga, senior vice president and general manager, Switch Products Group at Broadcom. “With these solutions vendors can leverage their investment in StrataDNX technology and software to span the whole carrier network with a single architecture.”
Broadcom said its StrataDNX product family now offers full-suite service-provider solutions including:
- Customer premises router / Network Interface Device (NID)
- Passive Optical Networking (PON)
- IP DSL Access Multiplexer (IP-DSLAM)
- Broadband Aggregation
- Packet Transport Node (PTN) and IP Remote Access Node (IPRAN)
- Carrier Ethernet Switching (CES) and Switch-Routing (CESR)
- Optical Transport Node (OTN) – both centralized and distributed
Broadcom’s Next StrataDNX Packs 100 Tbps of Switching Capacity
Broadcom introduced its next generation the StrataDNX (“Dune”) family of switch system-on-chip (SoC) devices for optical transport, carrier Ethernet, edge and core routers, data center cloud and enterprise campus market segments. Sampling is underway. The new switching StrataDNX silicon, like Broadcom’s StrataXGS Trident and Tomahawk switchhing families, are designed to power the next wave of network equipment with a higher port density, lower…
