The WinPath4 continuesthe carrier-grade Ethernet focus of its predecessors as the fourth generationof WinPath® products. Next generation protocols have been added along with a newlevel of performance, all the while supporting legacy applications andcontinuing Microchip's proven formula as a complete networking solution.

The WinPath4 integrates control plane andenhanced data plane processing components. Control plane processing is based ontwo high-performance MIPS 34K multi-threaded processors. Data plane processinguses dedicated hardware accelerators for packet classification, hierarchicalshaping, additional security standards and more to off-load common processingtasks. The accelerators are flexibly combined with a field-proven,fully-programmable, high-performance multi-threaded multi-core data pathprocessor subsystem. 48 cores are available (up from 12 in the WinPath3) andoperating speed has increased.
The WinPath4 leverages a broad set of suppliedprotocols developed over the years and hardened in production environments allover the world. These include support for interworking (MPLS, IPv4/IPv6Routing, VLAN-aware bridging), QoS (policing, shaping, per-flow queuing, WRED),Packet Network Synchronization (IEEE 1588v2, Synchronous Ethernet, adaptive anddifferential clock recovery), OAM (Ethernet, MPLS, ATM), L2 and L3 termination(Ethernet, ML-PPP, IMA, CES), PWE3 (Ethernet, TDM, HDLC, ATM) and more.
