Universal Scalable Network Architecture

This paper presents new, universal, scalable network architecture, called USA, which resolves the growing tensions between the Internet architecture and routing infrastructure. USA separates the identity of end host from its location and adopts name-based addressing to achieve the end-to-end communication. USA also isolates the address space of end sites from core Internet. Each end site possesses an address space, that avoids renumbering and address exhausting, and is multi-homed without inflating the default-free zone routing table. USA is designed to scalably solve the interconnection of heterogeneous networks, and attempts to provide better services like security, mobility, multi-homing and traffic engineering.
