Summary:
IoT systems tend to be silos which are built ground up for their particular applications. Fed4IoT is an EU-JP joint effort to federate IoT silos and make IoT devices and infrastructures shared among many IoT applications. This paper introduces the concept and the current architecture of Fed4IoT system. As a part of the Fed4IoT system, we are promoting to use service function chaining (SFC) to manage information to/from IoT devices within edge or in-network computing context. SFC provides a mechanism to reduce latency and distribute workload. Furthermore, Information Centric Networking (ICN) technology is adopted in addition to pub/sub communications, which is common among IoT system, to implement SFC. The name based forwarding in ICN gives us an opportunity to dynamically bind a function instance to a particular demand and consequently to meet the requirements in the demand. As an additional feature, the caching capability in ICN can be exploited to bring further reduction in latency and network load.
