A novel content-aware multipath routing concept exploiting random utility theory principles

This paper presents a novel multipath routing concept for content-aware networks, enabling better resource utilization and end-to-end QoS provision. Based on random utility theory and traffic identification techniques it delves into multinomial-type probability for efficient packet distribution among intra domain paths, by exploiting the capability of edge nodes to identify the content in transit, and proposes a network architecture where this concept may be applied. We focus on the methodology alterations that content-awareness will impose on the calculation of the utility that a corresponding packet will inherit in choosing a specific path, assuming that packets of “premium” content will have demanding QoS-centric network “taste” when they will have to choose a specific path.
