BCM88650 Device Grows To Terabit Size
?Broadcom continues on its new-products roll, launching the BCM88650 series of high-density 100 gigabit Ethernet (GbE) switching solutions it says enables “the design of switching platforms with densities up to 4,000 100 GbE ports.”
The BCM88650 system on chip (SoC), when combined with Broadcom’s FE1600 (BCM88750) fabric, “enables a new generation of high-density networking solutions exceeding 100 terabits per second (Tbps),” the company adds.
According to company literature, the BCM88650 series “is the only merchant silicon solution that can process a single stream of 200 Gbps traffic at Layer 2-Layer 4 with integrated advanced packet classification and deep-buffer traffic management features to support data center, carrier Ethernet and packet transport requirements.” In addition, a carrier access switching solution with a total capacity of a few hundred Gbps can be designed with a single BCM88650 device, while a chassis with a total capacity of 25 Tbps can be designed for the core of the data center or the carrier core network.
And to get even larger, “multiple chassis of different capacities can be interconnected to create a scalable core platform and deliver up to 4,000 wire-speed ports of 100 GbE or their 40 GbE/10 GbE equivalent,” Broadcom says.
More features of the BCM88650 (available sometime during 2H12):
>> Integrates advanced packet classification, deep-buffer traffic manager and cell-based fabric interface;
>> Integrated 1/10/40/100 GbE network interfaces help eliminate additional components;
>> Programmable packet-classification engine with built-in support for data center, metro Ethernet and transport applications;
>> Large on-chip classification databases can be extended using a companion Broadcom/NetLogic processor;
>> Deep buffers with distributed scheduling scheme allowing state of the art hierarchical QOS, transmission scheduling and flow control schemes;
>> Compatible with Broadcom’s XLP multi-core processors and NL8865x knowledge-based processors for control plane and expanded L2-4 header processing performance; and
>> Supported by Broadcom’s common Application Programming Interface.
