The active network in NASOS operating system

The role of computation within traditional packet networks, such as the Internet, is extremely limited. In an active network, however, the routers or switches of the network perform customized computations on the messages flowing through them. These networks are active in the sense that nodes can perform computations on, and modify, the packet contents. In this paper, we first introduce what an active network is, discuss the principle, the storage system hierarchy and the network of no address space operating system (NASOS), as well as the cross-domain call and file operations in NASOS. Then we discuss how NASOS implements the active network. Finally, we discuss its advantages
