Metro Ethernet Solutions
Providing the Highest Levels of Integration and Service Densities
Xelerated provides network processors (NPUs), software and design services for metro Ethernet switching and routing platforms. The X11 and the HX families of NPUs are highly-optimized devices for the metro Ethernet environment. The MEA data plane software provides feature-rich implementation of Carrier Ethernet standards as defined by the Institute of Electrical and Electronics Engineers (IEEE), Metro Ethernet Forum (MEF), the Broadband Forum, the International Telecommunications Union (ITU) and the Internet Engineering Task Force (IETF).
Xelerated network processors and data plane software targets the complete range of Metro Ethernet systems, from aggregation and service edge to the metro core.
Xelerated’s metro Ethernet solutions include technologies by complementary solutions partners, and can be fully customized to vendor specific designs. The programmable architecture allows for custom implementations and Xelerated's data plane software can be made available in source code for feature extensions and amendments.
The architecture is control plane OS independent. Large packet buffers and memories for tables, counters and meters enable range a network services, such as stateful session policy enforcement and seamless interworking with subscriber and service provisioning tools.
Xelerated Metro Ethernet solutions target a wide range of platforms, from cost-optimized pizza boxes to service-rich Ethernet/IP/MPLS chassis-based switch/routers.
Xelerated provides Metro Ethernet solutions based on Carrier Ethernet network processors, data plane software and solution partner products, coupled with professional services.
Pizza boxes can be designed for stacking configurations, utilizing Xelerated’s QMAP protocol. Line cards to high-density chassis-based systems are designed to interface to merchant SPAUI interfaces or to existing proprietary fabrics though Interlaken.
To accommodate high aggregation capabilities at low cost, Xelerated offers a range of design options for small to medium-sized chassis. These systiems utilize NPU deterministic processing capacity for distributed switching between line cards or interface modules.

Designs Examples
Modular High-density Chassis
Chassis-based solution with flexible port interface (I/O) cards. The line cards connect with redundant paths to a centralized switch fabric. Each line card features a common design based on the HX NPU. Note: Port I/O cards in this example show a small set of possible configurations.
100 GE Line Card
100GE line card using 100G Interlaken on system fabric and line interfaces. Uni-directional NPU board design allows for wirepeed performance of 100 Gbps.
200 Gbps Line Card Design Sample
200 Gbps traffic line card with flexible I/O port cards.
50 Gbps Wirespeed Service Line Card
Service line card featuring integrated traffic management and deep packet buffers stored in DRAM memory.
Aggregation Chassis
Aggregation chassis where the system switching is performed by the network processors distributed on the line cards. HX330 features integrated traffic management.
