Architectural overview

The picture to the right (click to enlarge) depicts the generall architecture of OpenTSP NG.

The core of VSN's OpenTSP NG portfolio consists of the Cavium Octeon-based Network Processing Unit which provides considerable network processing power with MIPS64 multi- core, hardware accelerated packet processing, cryptography, TCP and QoS.

OpenTSP NG Daughterboards (like Octasic Vocallo Media Processing Board or custom built) provide flexibility for specific needs, whilst higher level libraries (like Voice/Video Transcoding) and professional services enable easier, faster development thus shortening your time-to-market.
