Distributed control function selection method for service function chaining in NDN

Abstract

In this article, we discuss the function selection method in Function Chaining (NDN-FC) on Named Data Networking (NDN), which is an information-centric networking technology, in order to solve the problems caused by the increase in IoT devices. There is a previous study [10] on the function selection method in NDN-FC, but their proposal is a centralized approach and a coordinator overlooking the entire network is required. We propose a distributed control type function selection method. In order to implement this method, it is necessary to extend interest packet, data packet and forwarding of each node. We compared the existing method and the proposed method using ndnSIM, which is an NDN network simulator. The results of the proposed method are close to those of the method that requires the coordinator in terms of service execution delay and load balancing.
