HX Family of Network Processors
The HX family of high performance network processors represents the third generation of Carrier Ethernet devices. Based on Xelerated patented Dataflow Architecture these NPUs raise the industry bar for performance and level of integration, empowering a new wave of high service density Metro Ethernet systems.
Line-card-on-a-chip
The HX family provides 100 Gbps at wirespeed performance with a guaranteed number of operations and classification resources per packet, regardless of packet size and type. It integrates 10GE MAC, GE MAC and PHY, switching, advanced traffic management and programmable pipeline of processor cores into a single chip. This enables a range of system designs, from cost-effective intelligently over-subscribed aggregation pizza boxes to large-scale high available chassis-based systems.
Programmability enables feature differentiation and in-service adaptation to evolving standards and new services, thereby significantly prolonging product lifetime.
The HX family comes in different, footprint-compatible flavors. There is a choice of capacity, integrated Traffic Manager, and number of I/O interfaces including 100 Gbps Interlaken.
Product Options
The HX family has five product variants: HX336, HX326, HX330 and HX320. They differ in capacity, interfaces, and traffic management capabilities.
Design Example
See Metro Ethernet, Packet-Optical Transport and Cloud Computing solution sections for more examples on how to apply the HX family of NPUs to different systems.
