Next generation carriers Internet backbone node architecture are proposed that offer sophisticated QoS support including real time voice, video streaming, and VPN. The backbone core node, MSN (multi-service network) Type-X, has 320 Gb/s throughput and IP V4/V6 dual stack forwarding capability and OC-192C full wire-rate forwarding performance. In addition, sophisticated DiffServ having 4096 virtual queue realizing full hardware is also proposed. In addition, Type-X has ATM emulation technique. Finally, the paper describes a high-reliability technique such as a newly structured non-stop software and firmware upgrade technique. This newly proposed technique and system offers the next generation, real time, high-QoS capability.
