User-centered end to end optimal persistent routing

In this paper we present the end to end routing feature of computer networks, having user requests as central requirements for achieving optimal communication. End to end routing is the technology making people able to communicate via user-centered p2p applications, minimizing a network´s overall workloads, while keeping track of user application demands. Considered a research topic with a lot of focus on efficiency, portability, robustness and mostly reliability, user-centered design and it´s depiction in computer networks has been made possible, through the persistent routing aspect of networking technology.
