Next generation Internet backbone node architectures are proposed that offer sophisticated QoS support including real time voice, videostreaming, and VPN. The backbone core node, named MSN (Multi-service network) Type-X, has 320 Gb/s throughput and IP V.4/V.6 dual stack forwarding capability. Note that, through the employment of state-of-the art VLSI technology, both V.4 and V.6, OC-192C full wire-rate forwarding performance is achieved for the first time. In addition, sophisticated DiffServ with programmable thousands of virtual queues is also proposed to realize a complete set of hardware. In addition, Type-X uses an ATM emulation technique that can into allow the new packet centric backbone to support conventional services. Finally, the paper describes high-reliability techniques such as newly structured service non-stop software and a firmware upgrade technique. These newly proposed techniques and systems will realize the next generation, real time, high-QoS capability, and VPN IP backbone network to be realized.
