BROADCOM BCM88860A0KFRBG

Overview

The Broadcom® BCM88860 scalable Ethernet Switch Router Series is the industry’s most integrated networking solution, enabling high-density 800GbE switching and routing platforms with line rate MACsec and IPsec support.

The BCM88860 is the ninth generation of the StrataDNX scalable switching product line and processes up to 28.8 Tb/s of line card traffic, supporting up to 18 800GbE ports, 72 100GbE ports, or a mix of front panel ports from 50GbE to 800GbE, operating at Layer 2 through Layer 4.

The BCM88860 series, together with the BCM88920 fabric element (FE) device, enables system vendors to build a scalable product line based on a unified architecture that addresses any density or application, such as:

• Multi-terabit core and edge routers for data center, packet transport, or carrier network applications

• Large-scale spine and leaf switches for data centers with integrated deep buffering and hierarchical quality-of-service (HQoS)

• Multiple interconnected modular systems to create a scalable core platform for switching and routing capacity multiplication

• High-capacity, fixed configuration switch for mission-critical applications

The BCM88860 Elastic Pipe™ packet processor is C++ programmable, with built-in support for data center and carrier networking applications. The large-on-chip, centralized, and fungible databases are sized to scale to the most demanding service provider and cloud applications.

The BCM88860 traffic manager integrates deep packet buffers with a distributed scheduling scheme that allows state-of-the-art hierarchical quality-of-service (QoS), transmission scheduling per-customer, perservice, as well as tunneling and overlay networks. Flexible flow control mechanisms support Priority-based Flow Control (PFC), Enhanced Transmission Selection (ETS), and Explicit Congestion Notification (ECN).
