Abstract :
Due to historical reasons, the original model of existing information networks is that one network corresponds to one main service, and this mode can´t adapts well to increasing multi-demands of networks and services. So network architecture should be redesigned urgently based on new network concept and protocols. We have studied the main issues in future information network, and give the new architecture of future information network. According to research on theories of layer division of current various information networks, we find that the structure of every network can be divided into two basic layers, one is service layer and the other is network layer. Therefore we propose a new two-layer architecture model, that is “Pervasive Service Layer” and “Switching and Routing layer”. On “Switching and Routing layer”, we conclude that the routing principles of various networks are similar. They fulfill data exchanging and forwarding and have only few differences in data formats and services supported. So we propose generalized switching and routing theory, separating and mapping of access identifier, which is the core of universal network model and theory. On “Pervasive Service Layer”, we find that the principles of various networks are similar: all services (businesses) set up link first, then the link selects routes based on the switching and routing principle, and realize data transportation. Based on this similar principle, we propose the parsing and mapping theory between “service identifier” and “connection identifier”, which is the core of pervasive service model and theory, addressing the pervasive service issue.
