Information Centric Networks(ICN) can employ per-node forwarding strategies to provide an optimal transport service. This paper describes the design of an ICN Forwarder that implements Application-Adaptive Forwarding(AAF): an optimized multipath forwarding strategy for differentiated services that can adapt dynamically to changing link characteristics and implement different operator policies with respect to relative Quality-of-Service for different application classes. AAF is based on classifying available interfaces into different quality classes based on permanent RTT and loss rate observations. The paper describes the problems of existing (non-ICN) solutions in that space, explains why ICN is generally a better approach to multipath communication, describes the design and implementation of our approach, and provides an evaluation based on measurements in emulated networks.
