Newly emerging requirements of network application instant service bring in the challenges of a flexible, scalable, and reliable resource environment. Virtualization based resource isolation is helpful. However the internal structure of network software is often neglected in current virtualization based solutions. To improve resource sharing and utilization, the granularity of isolation should evolve from a single host to a network. NeTrOS, a virtual resource operating platform is proposed. Novel core concepts of cyber let and cyber-interrupt are introduced to express the first class runtime managed object and the evolution of virtual computing environment. Key technologies of virtual machine networks (VMNs), the implementation binding of cyber let in NeTrOS, are discussed. A programmable VMN architecture is proposed. Efficient maintenance mechanisms are involved to support the connectivity and dynamic nature of VMNs. Migrations of VMN in both LAN and WAN environment are supported. Detail implementation and deployment of NeTrOS are presented. A series of system evaluation is conducted to show the effectiveness and efficiency of NeTrOS. Experience of a mobile Internet application case supported by NeTrOS is also discussed.
