WinPath4

Overview

The WinPath4 continues the carrier-grade Ethernet focus of its predecessors as the fourth generation of WinPath products. Next generation protocols have been added along with a new level of performance, all the while supporting legacy applications and continuing Microsemi's proven formula as a complete networking solution.
The WinPath4 integrates control plane and enhanced data plane processing components. Control plane processing is based on two high-performance MIPS 34K multi-threaded processors. Data plane processing uses dedicated hardware accelerators for packet classification, hierarchical shaping, additional security standards and more to off-load common processing tasks. The accelerators are flexibly combined with a field-proven, fully-programmable, high-performance multi-threaded multi-core data path processor subsystem. 48 cores are available (up from 12 in the WinPath3) and operating speed has increased.
The WinPath4 leverages a broad set of supplied protocols developed over the years and hardened in production environments all over the world. These include support for interworking (MPLS, IPv4/IPv6 Routing, VLAN-aware bridging), QoS (policing, shaping, per-flow queuing, WRED), Packet Network Synchronization (IEEE 1588v2, Synchronous Ethernet, adaptive and differential clock recovery), OAM (Ethernet, MPLS, ATM), L2 and L3 termination (Ethernet, ML-PPP, IMA, CES), PWE3 (Ethernet, TDM, HDLC, ATM) and more.

Key Features

• More than 4x performance, higher integration than 3rd-generation WinPath3
• Extensive set of interfaces supporting IP and MPLS up to 10 GbE
• The ability to process and forward packet traffic (switching, routing,etc) using both internal switching mode (data buffers in internal memory) or external switching mode (large number of data buffers in external DDR memory) or a combination of both
• TDM/SDH up to OC-48 unchannelized or channelized (via companion UFE412 device)
• System bus interfaces include PCIe, integrated SERDES and Interlaken Look-aside
• Highly flexible integrated DDR3 and Flash memory controllers
• Powerful multi-threaded, multi-core acceleration with RAM-based code store supports evolving standards in Wireline (Carrier Ethernet, Enterprise Access, Mobile Backhaul, GPON, DSLAM) and Wireless (LTE, Microwave) systems
• Data path software is royalty-free and carrier-class supported with a C-language API for rapid system integration for over 60 protocols
• Available data path software supports networking at Layer 2 and above, interworking, QoS, and protocols such as MPLS, MPLS-TP, PB, PBB, EFM G.Bond, SAToP/CESoPSN, Link Aggregation, GRE, WRED, WFQ, VLAN-aware bridging and many others
• Rich suite of development tools and source code licensing options supports customer-specific requirements

Benefits
