On-Demand Routing for Chaining Multiple Functions in ICN-Based In-Network Processing

ICN (Information-Centric Networking) originally innovated for efficient content distribution, is now discussed to be applied to edge computing in IoT (Internet of Things) environment. In this paper, we focus on more flexible network processing environment, in-network processing, which is realized with ICN architecture. In our assumed environment, multiple functions are executed on different routers widely distributed in a whole network and the end-to-end optimal route for any data processing should be selected to satisfy various IoT applications' requirement. Our proposal, an on-demand routing method efficiently chains data and multiple functions compared to an existing proactive routing method. Also, our method reactively caches routing information in the network and realize scalable routing for ICN-based in-network processing.
