Ever increasing IP traffic with the resulting demand for greater capacity of the underlying Ethernet network has compelled most telecom operators to install IP/MPLS in their network core. This transfer to packet based networks brings higher throughput efficiency and lower costs, and has inevitably led to the replacement of legacy SDH/SONET circuit switched equipment. Whilst this fundamental shift has been necessary, the established operational advantages of SDH/SONET transmission – guaranteed Quality of Service (QoS), fast protection switching and minimal delay – are still essential and are becoming more vital as the range and demands of applications increase. In response for the real need of these features, packet network designers have introduced a variety of advanced networking protocols and QoS mechanisms which have inevitably increased both hardware and software complexity and correspondingly increased cost. Furthermore these techniques often result in proprietary solutions which dilute the benefits of competition. As a result MPLS networks have high CAPEX and OPEX and demand advanced levels of expertise to implement and manage, and often require sophisticated and expensive management and provisioning software.
The TransPacket Fusion approach (or “integrated hybrid network”) is a disruptive technology solving the problem of providing packet networks with the advantages of circuit switched networks. The Fusion approach combines the best of packet and circuit switching.
