WP3 WinPath3
Next Generation Access Systems
Packet Processor
Released Product Brief
Product Overview
The WinPath3, with its enhanced carrier-grade software, is the third
generation of WinPath products. Building on hundreds of successful
communications systems deployments, the WinPath3 extends PMC’s
proven formula of complete protocol solutions to a significantly
higher level of performance.
The WinPath3 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 new 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-perfor-
mance multi-threaded multi-core data path processor subsystem. 12
cores are available (up from 6 in the WinPath2) and operating speed
has increased.
The WinPath3 leverages a broad set of supplied protocols developed
for WinPath1 and WinPath2, including support for L2 and L3 termi-
nation (Ethernet, ML-PPP, IMA, CES), PWE3 (Ethernet, TDM, HDLC,
ATM), Packet Network Synchronization (IEEE 1588v2, Synchronous
Ethernet, adaptive and differential clock recovery), interworking
(MPLS, IPv4/IPv6 Routing, VLAN-aware bridging), OAM (Ethernet,
ATM), QoS (policing, shaping, per-flow queuing, WRED) and more.
Product Highlights
•
Third generation family of communication processors provided with
•
•
carrier-class IP protocol and interworking software
5x performance, higher integration than 2nd-generation WinPath2
Extensive set of interfaces supports IP up to 10 GbE and TDM/SDH
up to OC-48 unchannelized or channelized (via companion
UFE412/448 device)
System bus interfaces include PCIe, integrated SERDES
Highly flexible integrated DDR 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, WiMAX, Fixed Wireless Access) 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, PWE3-SATOP, 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

Reference Boards
The WinPath3 family is supported with WDS3 reference boards for
early software development while a customer’s own board is being
developed. WDS3 boards are also valuable for verifying functionality
when migrating to new software releases and for duplicating system
conditions for support purposes. WDS3 boards are offered standalone
and in standard ATCA form factors, so they can be used with any ATCA
chassis. They are available with various I/O options and adapter cards
to provide equivalent configurations for a range of applications.
