Service unit based network architecture

There are some limitations of current network architectures including functional duplication, error detection in multilayers and the repetition of addresses etc. We propose a novel network architecture called service unit based network architecture (SUNA). A node in the SUNA is reduced from the current 5- or 7-layers to two layers, i.e. an application layer on the top and a service layer underneath. Such reduction enables all the redundant functions and excessive overheads in existing network architecture to be wiped off, and hence improves the network performance and flexibility. A fringe benefit of the SUNA is to bridge the gap between network architectures and programmers and to enable protocol implementation to be carried out in a way that programmers are familiar with.
