Featured Partner




Asidua, based in the UK, is PMC-Sierra's longest standing software and control plane solutions partner for WinPath based systems.  The company has been successfully delivering WinPath based solutions to our customers since the first WinPath device was created more than ten years ago. The organisation has been with us on the WinPath journey through WinPath2, WinPath3 and recently has been the first to adopt WinPath4 as the latest generation platform underpinning the Asidua WanStaX software portfolio.  Asidua's WanStaX portfolio comes pre-integrated with WinPath and uniquely makes full use of WinPath hardware accelerated features.

With WanStaX, Asidua can provide highly cost effective working access network solutions based on WinPath with a very short development, integration and test cycle. WanStaX allows our customers to create access network systems supporting DSL, Carrier Ethernet, ATM, TDM, MPLS and PWE3 based services with close to zero software effort. The portfolio includes all the functionality required by MEF standard Network Interface Devices out of the box, including timing and synchronisation functions compliant to IEEE 1588v2 and SyncE. Many of the capabilities of WanStaX are readily available as functional demonstration builds which can be run on PMC's WDS development platforms for WinPath. In conjunction with Asidua's consultancy and professional services offering, WanStaX is a sure route to successful product delivery for WinPath based devices.

In addition, PMC and Asidua work closely on developing future proofed solutions for our customers; Asidua supports PMC’s technical roadmap in facilitating a migration path to SDN via OpenFlow. Please see the jointly authored white paper on this topic here,  which describes how WinPath allows carrier applications to fully exploit its fully programmable data plane, with Asidua’s WanStaX providing the software control and integration facilities to make this vision a reality. For further information see www.asidua.com/wanstax and Asidua WanStaX OpenFlow Demo.
